Mow and cover: Cover crop management using no-till practices in a market garden

Benjamin Alles, 2022

  • Key result: Covering a mowed cover crop with a tarp instead of tilling reduced time spent weeding in mulched organic cabbage plots.

Mustard seed meal, black soldier fly frass, spent mushroom manure compost, and Metarhizium brunneum for wireworm management in Hakurei turnips

Chelsea Allison, 2021

  • Key result: No reduction in wireworm damage to turnips was seen after soil treatment with black soldier fly frass, spent mushroom compost, defatted mustard seed meal, or Metarhizium brunneum fungus.

Effects of wood compost on soil health indicators in an organic loam

Sabrina Anderson, 2019

  • Key result: Wood-based compost boosts active carbon in soil, supporting larger microbial populations and more fungal colonies.

Effect of mowing on Sphagnumregeneration in a disturbed peat bog

Rue Badanic, 2022

  • Key result: Mowing cessation could promote Sphagnum moss regeneration in the degraded peat bog on Garden City Lands.

Spent mushroom compost as a replacement for peat in growing media

Alex Bisset, 2021

  • Key result: Aged spent mushroom compost can partially replace peat in seedling growing media without compromising yield. Soil blocks work as well as plastic plug trays.

Growth substrate effect on lion’s mane (Hericium erinaceus) mushroom yield

Steph Bulman, 2022

  • Key result: Growth substrate did not affect yield of lion’s mane mushrooms.

Do black plastic mulch and Metarhizium brunneum interact to protect beets from wireworm feeding?

Rachel Cassidy, 2022

  • Key result:Metarhizium brunneum increased beet yield when used with black plastic mulch. No yield benefit was observed when M. brunneum or plastic mulch were used alone.

Potential of halophyte phytoextraction for saline soil remediation

Sarah-Jane Copeland, 2020

  • Key result: Salsola, a salt-tolerant salad green, did not reduce salinity associated with spent mushroom compost application any more than salt-sensitive vegetable crops.

Effects of laser irradiation, organic fertilizer, and adjuvant on corn and cucumber yield

Nikita Ershov, 2020

  • Key result: Both laser treatment and fertilizer improved yields on their own, but benefits were not additive. Laser benefits were only observed in nutrient-poor environments.

Effect of Metarhizium brunneum application method on wireworm damage to potato

Jenna Graham, 2019

  • Key result: M. brunneum did not reduce wireworm damage or increase potato yield, regardless of application method.

Effect of Ascophyllum nodosum seaweed extract and powder on vegetative growth characteristics and foliar nutrient content of Vitis spp. hybrid cv. L’Acadie Blanc

Rob Hines, 2020

  • Key result: Grapevine growth was inhibited by high doses of seaweed powder but not seaweed extract.

Spent mushroom substrate for water conservation in squash production

Maria Jose Santander Mercado, 2020

  • Key result: Mulching with spent mushroom compost retains moisture and boosts spaghetti squash yield.

Seed and oil yield from canola in Richmond, BC

C. J. Nyereyegona, 2021

  • Key result: Excellent canola seed and oil yields were obtained from early, mid, and late spring planting dates.

Fresh spent mushroom compost mulch effect on bean, broccoli, salsola, and squash growth, weed suppression, and broccoli yield

James Oswald, 2020

  • Key result: Spent mushroom compost mulch suppresses weeds but not vegetables.

Early application of Metarhizium brunneum for management of wireworm in popcorn, Zea mays var. everta

James Reinert, 2020

  • Key result: Soil treatment with Metarhizium brunneum fungus before planting did not reduce wireworm survival or improve popcorn yield.

Leaf mold as renewable alternative to peat in seed starting media

Rosina Rodighiero, 2019

  • Key result: A blend of leaf mold, compost, and vermiculite successfully replaced the peat and vermiculite blend commonly used in vegetable transplant production.

Efficacy of fungicides available for powdery mildew control in certified organic squash production

Jordan Roper, 2019

  • Key result: Baking soda, milk, and Bacillus subtilis all slowed the spread of powdery mildew on organic squash.

Effect of pre-germination laser treatment on lettuce cultivated in a controlled environment

Ethan Simonyi-Gindele, 2021

  • Key result: Pre-germination laser seed treatment does not affect lettuce growth in a vertical farm.

Yield effect of flax (Linum usitatissimum) and chickpea (Cicer arietinum) intercropping

Moira Tarry, 2022

  • Key result: Dual purpose flax and chickpea had greater land output in mixed plantings than in monocultures. Flax dominated mixtures.
