Effects of fertigation on yield of day-neutral strawberry (Fragaria × ananassa) cultivars grown hydroponically in high tunnels
Strawberries (Fragaria × ananassa Duch.) are one of the most common fruits produced in the world. This small fruit is grown in all provinces of Canada and Quebec is considered as the Canadian leader in strawberry production. Field-grown strawberries faced telluric diseases that limit yields. To overcome phytosanitary problems, strawberries can be grown in soilless systems. This project aims to increase the yield of soilless grown everbearing strawberries by optimizing the fertigation. We compared three nutrient solutions to determine the K/Ca and K/N ratios to obtain the highest yield. Two genetic selections were studied: 'Seascape' and 'Charlotte'. Our results showed that plants need N during the vegetative phase as well as during the flowering-fruiting phase and that strawberries react positively to fertigation during these 2 phases.
