Summer and Fall Head Lettuce Variety Trials 2020 Research Report Seed Production, Selection & Breeding
Description
IN A NUTSHELL The growers’ objective was to document the best summer and fall head lettuce across different farms throughout southern and eastern Ontario during the 2020 season.
  • Magenta, Muir, and Nevada were the top varieties with respect to overall vigor, flavour, and germination in the summer.
  • Green Star was the growers’ least favourite variety overall in the summer.
  • Magenta, Ruby Sky, and Red Mist (from Vitalis Organic Seed) were the top varieties with respect to overall vigor in the fall.
  • Encino was the growers’ least favourite variety overall in the fall.
  • Red Mist (from another seedhouse) had poor germination rates, demonstrating that seed source – and not just variety – matters.

Effects of liquid and biological amendments on emergence and yield of no-till planted spring cereals 2020 Research Report Soil Health
Description
N A NUTSHELL To try to hasten emergence and improve yield of no-till planted spring cereals, Ken compared liquid amendment, biological amendment, a combination of amendments and a no-amendment control.
  • There was no observable difference in emergence due to amendments.
  • There was no significant difference in yield among the different treatments.

Assessing methods for nutrient application to prevent chlorosis in chestnuts 2020 Research Report Soil Health
Description
IN A NUTSHELL 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.
  • 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.

No-till fall broccoli in northern Ontario 2020 Research Report Cover Crops
Description
IN A NUTSHELL Ryan and Isabelle tested whether a crimped cover crop of rye and hairy vetch reduced tillage, cultivation and irrigation for their fall broccoli crop.
  • 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.

Direct seeding into compost mulch 2020 Research Report Soil Health
Description
IN A NUTSHELL 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.
  • 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.

Brocoli d’automne sans labour dans le nord de l’Ontario 2020 Research Report Soil Health
Description
EN BREF 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.
  • 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. Les pluies étaient suffisantes, de sorte qu’ils n’avaient pas besoin d’irriguer les parcelles de labour.
  • Le brocoli cultivé dans le paillis créé par la culture de couverture serti avait environ la moitié du rendement commercialisable par rapport aux parcelles labourées.
  • La perte de rendement combinée à l’absence de différence dans la main-d’oeuvre totale a rendu ce syst me sans labour, tel que testé, non viable pour la production de brocoli.

L’impact de l’utilisation des inoculants mycorhiziens pour sur les transplants de légumes 2020 Research Report Disease & Pest Control
Description
EN BREF Compte tenu de l’importance incroyable des champignons dans notre monde, Dianne était curieuse de savoir si les inoculants améliorent les rendements de la laitue et des oignons, ces deux espèces étant capable de grandir en relation avec les champignons mycorhiziens arbusculaires (AMF).
  • En 2019, elle a utilisé pour la première fois des inoculants AMF et a observé des laitues et des oignons particuli rement gros et sains.
  • En 2020, elle a mené un essai randomisé et répété comparant deux inoculants à des témoins non inoculé s pour la laitue Ariana, Cantarix, Nevada et Skyphos et l’oignon Patterson. Bien qu’ils soient également grands et sains, Dianne n’a détecté aucun effet sur le rendement des inoculants.
  • Elle se demande si la conception de l’essai était viciée parce qu’elle a inoculé et / ou ressuscité sans m fiance la communauté mycorhizienne de tout son jardin en 2019.

Assessing chronology of soil nutrient status in pastures across a topographic gradient 2020 Research Report Pasture Regeneration
Description
N A NUTSHELL To help him optimize pasture growth, Andy assessed soil nutrient status from the top slope, side slope and bottom slope of a 50–year old pasture and a hay field that he will start grazing in 2021.
  • Organic matter was higher in the older pasture but did not change significantly with topography.
  • Potassium, phosphorus and iron were also higher in the old pasture and potassium was higher on the top slope. Andy observed variations in manganese and copper for reasons that are unknown.
  • Andy’s observations of better soil health at the top of the hills weren’t supported by the basic assessment of soil nutrient status used in this study.

In search of short season northern grain amaranth varieties: A screening trial of grain amaranth (Amaranthus spp) 2020 Research Report Seed Production, Selection & Breeding
Description
IN A NUTSHELL Amaranth is climate-resilient and nutrient-dense, and is an important Indigenous plant of the Americas. To learn which varieties of amaranth are best suited for their region of southern Ontario, Ronaldo and Myriam compared five varieties of amaranth in an unreplicated screening trial.
  • They observed differences among the varieties in germination, flowering times, flowering patters and yield and think that Grain Amaranth from Richters Herbs and Atitlan Dorado from IMAP Guatemala merit consideration for a replicated trial.

Performance of Chantecler chickens on a reduced protein grower ration 2020 Research Report Livestock Feed
Description
IN A NUTSHELL Heather compared a standard protein ration with 16% protein to a reduced protein ration with 13% protein to see how her heritage Chantecler chickens responded during the grow-out period.
  • In 2019, Heather tracked the weight of three cohorts of chickens, taking more than 1,000 weight measurements of individual chickens.
  • There were no consistent differences in the weight of chickens on the two protein rations throughout the grow-out period.
  • There was also no detectable effect of reduced protein on finished live weight or dressed weight.
  • In 2020, Heather continued to use the reduced protein ration and would like to continue the trial over several seasons for more confidence.
