Planting methods for easyleaf type lettuce 2023 Research Project soil-health
Description

To optimize labour associated with planting of easyleaf lettuce, farmers at Fresh City Farms compared transplanting, direct seeding and a step-in method.

 

In a Nutshell
  • Among four succession plantings, there was a lot of variability and we were unable to discern clear differences between the three planting methods.

  • Trends and observations support that transplanting has the potential to be highest yielding; and, depending on soil conditions, the step-in method may reduce labour time.

  • The process of conducting a trial on the farm highlighted other areas for optimization, such as bed preparation, which ultimately led to greater yields in 2024.

Cover crops to regenerate fallow fields for vegetable production 2022 Research Project cover-crops, soil-health
Description
Over two years, Eric compared five methods of preparing fallow land for vegetable production with respect to soil regeneration and cost of implementation.

 

In a Nutshell

  • Cover crops with micronutrient amendments increased active carbon, a sensitive indicator of soil health and soil regeneration potential.

  • Micronutrient amendments alone did not increase active carbon.

  • Eric saw some added benefit of adding chicken manure and woody compost to the diverse cover crop, with respect to yield and cost effectiveness per unit biomass of an indicator crop of sorghum sudangrass.

  • Moving forward, whether Eric uses cover crops with or without manure and compost will depend on the return on investment of the following cash crop.

Farmer knowledge as formal knowledge: A case study of farmer-led research in Ontario, Canada 2023 Manuscripts community, cover-crops, disease-pest-control, seed-production-selection-breeding, soil-health, weed-control
Description
Abstract

Farmer-led research (FLR) is a process of inquiry wherein farmers use scientific methods to address their own on-farm curiosities and challenges in ways that are compatible with the scale and management style of their operations. With its flexible, adaptable, participatory, grassroots-oriented nature, FLR has typically been employed by farmers interested in ecological farming techniques and technologies, and evidence shows that it contributes to the adoption and improvement of ecological management practices across a range of contexts. Engagement in FLR initiatives has also been linked to positive social outcomes, including community building, farmer empowerment, and enhanced capacity for leadership and collective action. In this paper, we present a case study of the Ecological Farmers Association of Ontario’s (EFAO) Farmer-Led Research Program (FLRP), which is currently one of relatively few FLR initiatives in North America. We draw on data from a participatory, mixed-methods research project. Our results highlight how the FLRP is enabling farmers to feel more knowledgeable, confident, motivated, and inspired to adopt and/or improve ecological practices on their farms, in part by supporting them in building robust social networks that align with their farming values and priorities.

Description

The growers’ objectives were to document the best iceberg lettuce varieties for successional head production across different farms in southern Ontario; and to assess the viability of the varieties for seed production in Zone 3 in northern Ontario.

In a Nutshell

  • Iceberg can be a difficult lettuce to grow and market because of the variability and inconsistencies in head development
  • Due to issues with replication, no concrete recommendations can be made on which iceberg variety is best for successional head production in southern Ontario
  • Two varieties that rose to the top for growers were Laibacher Eis 4 and Marius, both of which came from a co-operative organic breeding network in Germany
  • Due to disease pressure, no seed was produced in Zone 3 from any of the iceberg varieties

Red pepper variety trial for Ontario and British Columbia 2022 Research Project seed-production-selection-breeding
Description

Mike and the other farmers wanted to document the best red pepper varieties for production across different farms in southern Ontario and on one farm in British Columbia.

In a Nutshell

  • Ace F1 is still the red pepper to beat in terms of productivity and flavour
  • Some growers around Guelph experienced extreme levels of pepper maggot infestation, which prevented some data collection for the trial
  • Most Ontario growers mentioned that they would not likely grow these varieties of red peppers outdoors again, but instead would stick to poly tunnels or hoophouses as yields and quality are better
  • Ace F1, Sprinter, and Crimson Carillon surfaced as favourites for the unreplicated hoop house trial in British Columbia

Screening of quinoa transplant date and viability 2022 Research Project
Description

In a continuation of his 2021 quinoa variety screening trial, Dean screened the viability of transplanting quinoa for five seeding dates and two transplant dates.

In a Nutshell

  • Quinoa can be successfully grown from transplants and this method offers excellent weed control under organic management
  • The efforts and cost of transplanting labour appears to be feasible with the high price of organic quinoa
  • Dean believes that with no difference in germination and transplant survivability, earlier transplanted quinoa would be easier to manage with a longer harvest window and less possibility of head sprouting in the fall

When is intensive too intensive? The production of table beets in three vs. four row spacing Research Project weed-control
Description

Ann wanted to know if there was a yield benefit to growing four-row compared to three-row beets in a three foot bed system. She also wanted to investigate whether there is a difference in labour required for weeding and disease pressure between the two systems.

In a Nutshell

  • Using an Earthway seeder with no thinning, Ann found no difference in beet yield between three-row and four-row plantings.
  • Ann observed three-row beets were less labour intensive for weeding and that she could use time-saving tools like a wheel hoe longer into the season.

Quantifying plant available nitrogen from cover crops 2022 Research Project cover-crops, soil-health
Description
Jesse and Meghan wanted to understand the contribution of spring legume cover crops
towards the nitrogen requirements of the following cash crop. They established a randomized
block design with low- and high-legume cover crop treatments. They sampled cover crop
biomass and used lab analyzes paired with a free online calculator from Oregon State
University to estimate plant available nitrogen (PAN) from the cover crops, and also tested
an in-field method to estimate PAN. Finally, they took soil nitrate samples throughout the
growing season to better understand the best tools to manage his fertility.

In a Nutshell

  • Legume cover crop mixes can supply a lot of PAN, potentially in excess of the needs of some vegetable crops.
  • Cover crops act as an effective catch crop by reducing soil nitrate early in the season.
  • Legume content in a cover crop mix moderates in-season PAN as indicated by soil nitrate.
  • Cover crop biomass sampling coupled with lab analysis and the online calculator provided a simple, cost effective tool for quantifying PAN contribution of cover crops.
  • Both pre-plant and mid-season soil nitrate-nitrogen sampling were effective tools for predicting PAN availability when Jesse and Meghan compared their results to the literature.

Assessing methods for nutrient application to prevent chlorosis in chestnuts 2020 Research Project disease-pest-control, soil-health
Description

To prevent chlorosis in chestnuts, Derick compared broadcasting and localized application of nutrient amendments to no amendment controls. After a year of growth, he measured tree height and leaf nutrient status.

In a Nutshell

  • Derick detected no difference in plant health or leaf nutrient status between the two amendment methods. Given the extra labour involved with the localized treatment, he will not broadcast any amendments moving forward.
  • He detected higher leaf potassium levels in the amended trees, which is important for iron availability in the plant.

Direct seeding into compost mulch 2020 Research Project soil-health
Description

To reduce tillage for crops that are direct seeded, Jason tested different composts in a no-till deep bed system in one trial each of lettuce and carrots.

In a Nutshell

  • The substrates for deep compost mulch differed with respect to growing lettuce and carrots, but bare ground control produced the highest seedling count for lettuce and the greatest yield for carrots.
  • Optimizing the use of deep bed compost requires a systems approach since seeding depth and irrigation rate, etc. differ by substrate. It was not practical, however, for Jason to test each substrate in a systems- context which limits the applicability of these results.

Efficacy of mycorrhizal inoculants on vegetable transplants 2020 Research Project disease-pest-control, soil-health
Description

Given the incredible importance of fungi in our world, Dianne was curious if inoculants improved lettuce and onions yields, as these two species are known to grow in relationship with arbuscular mycorrhizal fungi (AMF).

In a Nutshell

  • In 2019, she used AMF inoculants for the first time and observed particularly large, healthy lettuce and onions.
  • In 2020, she set-up a randomized and replicated trial comparing two inoculants to uninoculated controls for Ariana, Cantarix, Nevada and Skyphos lettuce and Patterson onion. While they were also large and healthy, Dianne detected no effects of the inoculants yield.
  • She wonders if the design of the trial was flawed because she unsuspectingly inoculated and/or resuscitated the mycorrhizal community of her whole garden in 2019.

No-till tomatoes 3-ways 2020 Research Project cover-crops, soil-health, weed-control
Description

To further explore no-till techniques, Matt compared no-till tomatoes three ways: compost + landscape fabric, compost + cover crop + landscape fabric, and compost + cardboard + landscape fabric.

In a Nutshell

  • He detected no difference in cumulative or monthly tomato yield among the three methods.
  • He also detected no difference in water infiltration, an indicator of soil health, among the three methods.
  • This data indicates that adding cardboard or cover crops to compost and landscape fabric does not improve yield for no-till tomatoes; and cardboard and cover crops may be a useful means of further building soil without negative effects on yield.

No-till fall broccoli in northern Ontario 2020 Research Project cover-crops, soil-health, weed-control
Description

Ryan and Isabelle tested whether a crimped cover crop of rye and hairy vetch reduced tillage, cultivation and irrigation for their fall broccoli crop.

In a Nutshell

  • Compared to tillage, the cover crop residue provided sufficient mulch to significantly reduce weeding time and increase soil moisture throughout the growing season by 11%. There was adequate rainfall, so they didn’t need to use irrigation in the tillage plots.
  • Broccoli grown in crimped cover crop mulch had around half the marketable yield compared to the tilled plots.
  • The yield loss combined with no difference in total labour made this no-till system as tested unviable for broccoli production.

Description

Ryan et Isabelle ont testé si une culture de couverture sertie de seigle et de vesce velue réduirait le travail du sol, l’entretien de la culture et l’irrigation pour leur récolte de brocolis d’automne.

En Bref

  • Par rapport au travail du sol, les résidus de culture de couverture ont fourni suffisamment de paillis pour réduire consid rablement le temps de d sherbage et augmenter l’humidité du sol tout au long de la saison de croissance avec 11% plus d’humidité que la parcelle de contrôle.

Grafting for organic low-tech greenhouse tomatoes 2020 Research Project seed-production-selection-breeding
Description

As a follow-up to their 2019 multi-farm trial, we compared 5 large tomato varieties and 4 cherry tomato varieties grown by grafting onto four different rootstocks and an ungrafted control.

In a Nutshell

  • The best choice of rootstock was specific to the scion, with some rootstocks producing no improvement
    or even reducing yield for some varieties of scion.
  • Compared to ungrafted plants, Caiman F1 large tomatoes had great yield and profitability when grafted DR0141TX rootstock.
  • Preliminary data suggest that only Sakura cherry tomato may benefit from grafting on Fortanimo or Estanimo, but more replicates are needed to be confident.

No-till broccoli with landscape fabric in northern Ontario 2021 Research Project soil-health, weed-control
Description

As a continuation of their no-till broccoli trial in 2020 using cover crops, Ryan and Isabelle tested no-till broccoli using landscape fabric in 2021.

In a Nutshell

  • Broccoli grown using the no-till treatment of landscape fabric had lower yield and required more labour.
  • Despite poor performance of no-till broccoli using mulches, Ryan and Isabelle still believe that fall broccoli in northeastern Ontario can be grown successfully in a no- till system, and will likely try no-till broccoli without a mulch system (cover crop or fabric) in 2022.

In search of short season northern grain amaranth varieties: A variety trial of grain amaranth (Amaranthus spp.) 2021 Research Project seed-production-selection-breeding
Description

The growers’ objective was to document the best short season northern grain amaranth variety for production across different farms throughout southern Ontario during the 2021 growing season.

In a Nutshell

  • Golden Giant, Opopeo, and Atitlan Dorado all performed well and were overall favourites among the growers.
  • The Grain Amaranth from Richters Herbs was the growers least preferred variety and didn’t perform as well as the other varieties but ranked top in flavour for growers.
  • Despite this, growers are interested in adapting this variety because of its good flavour, early flowering, and wide genetics which they hope means they can work with the population to create an ideal variety for their farm.
  • Growers’ enjoyed learning about grain amaranth production and its story but more work is needed to determine if production at the small and mid-sized scale is feasible with the harvesting and processing labour time.

Quinoa screening trial 2021 Research Project seed-production-selection-breeding
Description

In 2021, Dean assessed 6 varieties of quinoa under organic management practices. The goal was to choose the best suited variety for future large-scale production and direct market sales to local consumers.

In a Nutshell

  • Quinoa is a slow growing, non-competitive plant that can be a finicky crop to produce!
  • It’s hard to differentiate between closely related weeds such as lamb’s quarters during the first 8 weeks of production.
  • In a direct seeded quinoa crop, traditional large scale organic weeding practices were challenging, and the use of a rotary hoe was deemed impractical.
  • Buffy and Brightest Brilliant Rainbow were the best performers in this trial under 2021 conditions.

Do soil covers differ in their efficacy for production of organic greens? 2019 Research Project community, soil-health, weed-control
Description

As a follow-up to Brent and Gillian’s tarp trial last year, these growers evaluated the difference among tarp, landscape fabric and clear plastic for greens production.

Key Findings

  • Occultation worked consistently for weed and residue management. Between tarp and landscape fabric, landscape fabric is much easier to manage.
  • Clear plastic was not effective during shoulder seasons, when temperatures aren’t warm enough.
  • The soil covers did not affect crop yield differently.
  • Soil moisture retention was better with occultation, and soil moisture was highest under landscape fabric.
  • Depending on farm and time of year, soil temperature peaked under all covers and uncovered soil, suggesting that occultation does not increase soil temperatures to a point that negatively affects soil biology.

Management sensitivity, repeatability, and consistency of interpretation of soil health indicators on organic farms in southwestern Ontario 2019 Manuscripts soil-health
Description
Abstract
Assessment tools are needed to evaluate the effect of farming practices on soil health, as there is increasing interest from growers to improve the health of their soils. However, there is limited information on the efficacy of different soil health indicators on commercial farms and perhaps less so on organic farms. To assess efficacy, three organic growers in cooperation with the Ecological Farmers Association of Ontario’s Farmer-Led Research Program tested management sensitivity, measurement repeatability, and consistency of interpretation of different soil health indicators. On each farm, we compared permanganate-oxidizable carbon (active carbon), organic matter, wet aggregate stability, phospholipid fatty acid analysis, Haney soil health test, and Haney nutrient test on one field of grower-perceived high productivity, one field of grower-perceived low productivity, and one reference site (undisturbed, permanent cover). Our results were consistent with previous research that showed grower perception of productivity and soil health associated with management-sensitive soil health indicators. Of the indicators tested, active carbon was the only indicator that was sensitive, repeatable, and consistent across the three farms, and soil organic matter was highly repeatable and consistent to detect differences greater than 0.5% organic matter. This study highlights differences among soil health indicators on commercial farms, and it concludes that active carbon and organic matter were the most useful soil health indicators for these organic farms. Participating growers intend to use results to benchmark current soil status and to help guide land management decisions towards improved soil health.

To compare different varieties for fall growing, these farmers – in consultation with Johnny’s, High Mowing and Fedco seed companies – selected 11 lettuce varieties of interest. Each grower chose a subset and everyone committed to planting two replicates of each variety in their last two plantings of lettuce.

Key Findings

  • Magenta, a red/green batavian, and Ruby Star, a red leaf, were the top performers with respect to overall vigor, flavour and germination.
  • Adriana was the growers’ least favourite.

Is no-till planting spring cereal grain into winter-killed cover crops worth it? 2019 Research Project cover-crops, soil-health, weed-control
Description

Spring cereals are integral to diverse rotations; however, it is often hard to get them planted early enough. One strategy to get into the field early is to no-till plant into cover crop residue, which provides soil cover in the winter and generally helps improve soil health. To investigate this approach, Ken no-till planted oats and barley into replicated plots of four different cover crops and plots that received fall tillage. 

Key Findings

  • Grain yield and relative net return were highest when no-till planted into daikon radish.
  • Weed control was best with daikon radish and the fall tillage control.
  • There was no soil erosion in the cover crop plots, and moderate rill erosion in the fall tillage plots.

Do grafted tomatoes pay off in high tunnels in Ontario? 2019 Research Project community, seed-production-selection-breeding
Description

Grafting is a proven way to incorporate disease resistance into tomato transplants. However adoption of this practice to high tunnel production is relatively new, so these four growers were curious about the economic viability of grafting tomatoes for production in high tunnels in southern Ontario.

Key Findings

  • Grafted tomatoes had greater total marketable yield regardless of scion variety.
  • Grafted tomatoes had greater overall plant health.
  • Grafted tomatoes had higher net returns on average but the degree of economic benefit varied by farm.
  • Yield advantage for grafting likely depends on scion variety and scion and rootstock compatibility.

Toward community food security through transdisciplinary action research 2019 Manuscripts community
Description
Abstract

To solve the world’s most complex problems, research is increasingly moving toward more transdisciplinary endeavors. While a lot of important work has explored the characteristics, challenges, opportunities, and operationalization of transdisciplinary research, much less is known about the circumstances that either facilitate or hinder the research process, particularly from the perspectives of graduate students who often participate in them. In this paper, we aim to address this gap by contributing our own experiences as a team of four graduate students and one community partner that collaborated on a food security project. To support our collaboration, we develop and apply an analytical framework that integrates transdisciplinarity and action research. Through principles of reflexivity, participation and partnership, methods and process, and integration, we find that the framework facilitated the development of shared purposes, mutual responsibility, and meaningful relationships, resulting in the cocreation of a guidebook for farmer-led research. Our main concern with the framework is not achieving the full integration of our disciplines and practices. Transdisciplinarity together with action research holds significant promise in a food security context, but only in the “right” circumstances, where considerable time is spent building relationships, opening communicative space, and reflecting on the work with collaborators.

Agroecology in Canada: Towards an Integration of Agroecological Practice, Movement, and Science 2018 Manuscripts community
Description
Abstract

This article surveys the current state of agroecology in Canada, giving particular attention to agroecological practices, the related social movements, and the achievements of agroecological science. In each of these realms, we find that agroecology emerges as a response to the various social and ecological problems associated with the prevailing industrial model of agricultural production that has long been promoted in the country under settler colonialism. Although the prevalence and prominence of agroecology is growing in Canada, its presence is still small and the support for its development is limited. We provide recommendations to achieve a more meaningful integration of agroecology in Canadian food policy and practice.

Does tarping between succession plantings reduce the amount of tillage and labour required for organic salad production? 2018 Research Project soil-health, weed-control
Description

With the goal of regenerative farming, Brent and Gillian want to minimize tillage for their organic salad greens production. To do this, they trialed tarps to kill residue between succession plantings and recorded the management needed to direct seed. They also tracked labour, including time moving and placing tarps and hand weeding.

Key Findings

  • Tarping soil, without tilling before tarping, reduced tillage by 82% and resulted in faster growing crops.
  • It also reduced total labour 60% for lettuce and spinach crops because of fewer weeds.
  • It increased total labour by 65% for mustard greens, which do not require weeding.

Does ultra high density grazing as part of adaptive multi-paddock grazing have merit in Ontario? 2018 Research Project pasture-regeneration, soil-health
Description
Adaptive multi-paddock (AMP) grazing uses short grazing intervals followed by long rest periods. By doing so, this system allows for plant recovery, promotes optimal plant communities, protects against erosion and leads to net carbon storage in the soil (Stanley et al 2018). To optimize his grazing, Tony assessed the benefits of ultra high density grazing as part of his AMP approach. Specifically, he tested whether a single pass of mob grazing would provide a “hit and boost” to his pastures. Key Findings:

  • The amount of forage consumed was the same, irrespective of standard or ultra high density grazing.
  • Tony found no difference in pasture recovery between standard and ultra high density grazing.
  • Tony will graze these areas in a similar way next year to see if a second year of a “hit and boost” has benefits.

Is lettuce seed production in northern Ontario improved using a hoop house? 2018 Research Project seed-production-selection-breeding
Description

Northern Ontario faces specific challenges compared to other parts of the province when it comes to seed production, including late springs and early frosts (as early as end of August), followed with a wet fall. The demand for lettuce and greens seed is high, but these growing conditions make producing lettuce seed outdoors very difficult. This means that northern seed producers cannot produce regionally adapted varieties. As a potential solution to lettuce seed production in northern Ontario, Peggy compared seed production in a hoop house and uncovered.

Key Findings

  • In the hoop house, Peggy grew sellable lettuce seed from 4 of 5 varieties, and sales of the seeds would recoup hoop house material costs in 2.21 years.
  • When grown uncovered, none of the 5 varieties produced viable seed.

Pasture-raised chicken breed comparison 2016 Research Project livestock-breed-selection, nutritional-quality-of-food
Description

Jason Hayes raised groups of Nova Free Ranger and White Rock chickens on pasture and measured feed intake, carcass yield, taste and nutritional quality.

Key Findings

  • From one successful replicate, the Nova Free Ranger group had a lower (better) average feed conversion ratio and greater return to labour ($5.30/kg vs. $5.05/kg).
  • Blind taste tests suggest the taste and texture of Nova Free Ranger meat is preferred by culinary professionals but that the average non-chef customer may prefer the smoother texture of White Rock meat.
  • Average OMEGA 6:3 ratio of one White Rock and one Nova Free Ranger was 9.5:1, higher (worse) than previously published results from pasture-raised chickens but lower (better) than previously published results from non-pasture-raised chickens. Vitamin content was higher than all previously published results.
  • Delayed arrival of Nova Free Ranger chicks allowed analysis of only one replicate in 2016, so additional replicates are needed to draw conclusions​.
  • Evaluating the nutritional quality and profitability of alternative breeds on pasture helps producers choose breeds that are better suited to integrated, pasture-based farming.

What is the best variety of sweet pea to grow in southern Ontario? 2018 Research Project seed-production-selection-breeding
Description

Much of the flower seed being produced and used by cut flower growers across Canada is grown internationally in the Netherlands, Israel, and various South American and African countries. This means that varieties are not adapted to the Canadian climate and flower growers can’t support local seed houses. Jessica wanted to assess different varieties from local seed houses to find the best one for her farm, and she enlisted the help of other flower growers.

Key Findings

  • There was not a detectable difference in plant quality among blush or white varieties.
  • While there was not enough data to analyze statistically, Jessica recorded differences in bloom period and vase life. In doing so, she gained insight into the importance of these factors – especially in hot southern Ontario – for future variety trials of Sweet Peas.

This project compared yield and labour for garlic planted into established oats, garlic and oats planted together, and garlic without a cover crop.

Key Findings

  • Garlic survival and proportion of medium garlic was highest when garlic was planted with oats or into bare soil (control); and lowest when garlic was planted into an established oat cover crop.
  • Garlic planted into an established cover crop required more planting labour and delayed emergence.
  • Delayed emergence, in turn, delayed weeding and allowed perennial species to establish.

Quick turnaround cover crops before brassicas 2016 Research Project community, cover-crops, soil-health, weed-control
Description

Part of a multi-farm trial on five farms asking the research question: Do spring planted cover crops benefit the production of late season brassica cash crops?

Summary

  • Organic vegetable growers use cover crops to improve soil fertility and tilth and control weeds.
  • Five growers evaluated summer cover crops to determine benefits to N-demanding late season brassicas.
  • Specific cover crop comparisons included bell/fava bean (legume) vs. no cover crop control; cocktails containing a legume (bell/fava bean, peas, white clover) vs. buckwheat control.

Key Findings

  • Dry conditions in the spring impeded germination resulting in “lacklustre growth [that was] not nearly competitive
    enough to deter weeds” or mature enough to effectively mow, resulting in very little meaningful cover crop or

Do organic sprays differ in their efficacy against disease in black walnut? 2018 Research Project disease-pest-control
Description

Joseph and Jazmin compared organic sprays for managing disease in their young orchard, with the goal of discovering the best organic approach to care for their black walnuts.

Key Findings

  • Disease and insect pressure was low on the young trees measured this year.
  • While there was no statistical difference between the two treatments (neem oil vs copper and biological insecticide). They will continue measurements for a second year.
  • The most significant indicator of fungal infection is early defoliation in the fall. Therefore, observations next year at the end of the season could strengthen their overall conclusions.

Living and dry spring mulches in garlic 2017 Research Project cover-crops, weed-control
Description
Garlic on small organic farms is typically either dry mulched (e.g. straw) or grown in bare soil and cultivated for weed control. Farmers would like to see the soil covered to prevent erosion, increase water retention, and improve soil nutrition. However, water retention could increase nematode pressure and green mulches could compete with garlic. Ken set out to see if there was a difference in yield of marketable garlic between cultivation and spring mulches.

In search of short season northern sweet potato varieties: Selection and evaluation of new sweet potato (Ipomoea batatas) crosses 2019 Research Project seed-production-selection-breeding
Description

As demand for sweet potatoes grows in Canada, breeders are working to create sweet potatoes that are adapted to eastern Ontario. In the first year of the project, Kate selected sweet potatoes that are best suited for low input, organic systems in eastern Ontario.

Progress to Date

  • Kate evaluated nearly 60 genetically unique and
    diverse sweet potato tubers.
  • After final evaluations of taste and storability, Kate
    will choose 15 varieties and trial them in 2020.
  • Kate collected seeds from the vines that produced
    seed, which is germplasm for future breeding.

Cabbage seed production 2017 Research Project seed-production-selection-breeding
Description
Rebecca and Nicola compared two methods of cabbage seed production:

  • The “Fruition” or “pyramid” method, learned from Petra and Matthew at Fruition Seeds, where the head is trimmed like a pyramid such that leaves are usable but not sellable and;
  • An alternative “Meadowlark” or “chop” method, learned from Beth and Nathan at Meadowlark Hearth Biodynamic Seeds, that removes the head in a way that it can be sold at winter or spring markets.
