The aim of this study was to investigate the different combinations red (R) and blue (B) light emitting diode (LEDs') lighting effects on growth, pigment content, antioxidant capacity in lettuce, spinach, kale, basil, pepper a growth chamber. chamber equipped with R B percentages based total intensity: 83% + 17% B; 91% 9% 95% 5% control 100% R. photosynthetic photon flux density (PPFD), photoperiod, temperature, relative humidity were maintained at 200 ± 5 μmol m-2 s-1, 16 h, 25/21 2.5 °C,...

Even though the benefits from use of charcoal in agriculture have been known for a long time, little biochar is utilized agriculture. Therefore, we hypothesized that amendment to an organic potting soil improves plant without promoting root pathogens such as ultimum. Growth sweet pepper, lettuce, basil, geranium coriander grown...
The effects on plants of commercial applications biofertilizer and biocontrol agents containing planktonic rhizobacteria cells are inconsistent mainly due to an unsuccessful competition with existing endogenous microbial communities. present study investigated inoculants in the form biofilms, which dense colonies single or multi-species cells, adherent either biotic abiotic surfaces, encased a self-produced matrix composed extracellular polymeric substances. Bacillus sp., Pseudomonas mixed...

Aquaculture systems generate large amounts of wastes which may constitute a beneficial amendment for horticultural crop terms nutrients, plant promoter disease suppressiveness. This study aimed to determine (1) the nutrient value rainbow trout farming coming from two feed regimes (2) suppressiveness effects those fish on...
Floodplains are unique environments that provide a dynamic link between terrestrial and aquatic systems. Intensification of human activity – particularly agriculture urbanisation has resulted in the degradation floodplains worldwide. Restoration sustainable management requires holistic assessment compromise stakeholders to successfully balance environmental, economic, social benefits. Yet, understanding these complex systems sufficiently evidence-based recommendations is challenge. We...

Emerging contaminants were found to alter the soil microbial community composition. However, no changes observed when these compounds added containing 100 mg kg −1 HDPE microplastics.
Twenty-eight microorganisms showing in vitro antagonistic activity against Pythium ultimum were tested for their ability to reduce root rot [P. ultimum] on mature tomato plants grown a greenhouse under hydroponic conditions. Of those, Penicillium brevicompactum, solitum strain 1, Pseudomonas fluorescens subgroup G 2, marginalis, putida B syringae and Trichoderma atroviride shown strongly severity, improve the anchorage, increase marketable yields of rockwool infested with P. ultimum....
Organically grown greenhouse sweet pepper crops, as is the case with most year-around rely on pre-grown transplants. Production of adequately balanced (source and sink strength potential) healthy organic transplants a challenge often related to early total harvested yields. Liquid and/or solid fertilizers for were compared conventional liquid fertilizer. Transplants under conditions inoculated, or not, beneficial microbial agent, Trichoderma harzianum Rifai, strain KRL-AG2 (Rootshield®)....
Day-neutral (DN) strawberry cultivars are increasingly grown in Canada because they produce flowers and fruits continuously until October. Appropriate artificial lighting conditions during preparation of high-quality transplants is critical. Unfortunately, systematic evaluation appropriate transplant production limited. The objective this study was to determine how an extended photoperiod supplemented with different light quality affects the vegetative reproductive growth a day-neutral...

Pythium root rot, caused by ultimum , is responsible for important losses in geranium plant production, mainly as a result of the decrease overall quality. An organic production system plants based on fertilization using filtered suspension dehydrated hen manure was compared with conventional to evaluate their tolerance disease. Under typical greenhouse conditions, were inoculated Pseudomonas putida Trichoderma atroviride mixture both or harzianum and commercially available product,...
Untreated greenhouse effluents or leak solution constitute a major environmental burden because their nitrate and phosphate concentrations may induce eutrophication.Artificial wetlands offer low cost alternative treatment of consequently improve the sustainability growing systems.The objectives this study were to 1) characterize efficiency different types wetland reduce ion content tomato effluent, 2) by adding carbon 0-800 mg L -1 sucrose.Experiments conducted at Laval University where 30...
Field exposition showed low effects of polymer and silica-based nanopesticides on strawberries (bioaccumulation, biometrics) soils (accumulation, soil enzyme activities).
The stem and bulb nematode, Ditylenchus dipsaci, is a plant-parasitic nematode affecting over 500 plant species worldwide. Since 2012, garlic producers from Ontario Quebec have been particularly affected with economic losses caused by this pest. Reproduction of D. dipsaci on particular host depends its biological race, races are unknown for these populations eastern Canada. As polyphagous pest, can possibly be threat negative impact many crops grown in Quebec, such as field vegetable (e.g.,...
