Biological features of growing tomatoes in closed agroecosystems

Researches were conducted in 2019-2020 the department of closed artificial agroecosystems for plant growing on basis Federal State Budgetary Scientific Institution “Federal Agroengineering Center VIM”, Moscow. The object study was seeds tomatoes Solanum lycopersicum L. aim research to effect a biostimulant (succinic acid) biological characteristics and productivity grown substrate hydroponics climatic chamber. As result researches, there identified most effective method using succinic acid as biostimulator – inoculation seeds, which contributed an increase yield with significant rise relation control 64.1%. average fruit weight this variant 114.1 g, exceeds by 37.0%. complex application provided 18.6%, addition nutrient solution is 4.1%.
