The research was carried out during January to February, 2021 under shade net condition, Department of Horticulture, SHUATS, Prayagraj, Uttar Pradesh. The experiment was conducted in Randomized Block Design (RBD), with eight treatments and replicated thrice in hydroponic system with Spinach beet variety All-green. It was found that the T₇ (Epsom salts and micros (17.5 ml/10 L) (MnSO₄, ZnSO₄, CuSO4, B, Common Salt) + Iron Chelate (17.5 m1/10 L) + Mono Ammonium phosphate (17.5 ml/10 L) N:P:K 11:48:00 + Calcium Nitrate (27.5 ml/10 L) N:P:K 15:00:00 + Potassium Nitrate (27.5 ml/10 L) N:P:K 13:00:44 was found superior over other treatments in terms of yield and economics of spinach beet under hydroponic system. Maximum gross return (Rs. 973.32/structure) and net return (Rs. 292.38/structure) with highest benefit cost ratio (1:1.67) was also obtained in T₇.
