Effect of Different Levels of NPK and Micronutrients for Plant Growth, Bulb and Quality of Onion (Allium cepa) in NFT System of Hydroponics

Aims: To evaluate the effect of different levels NPK and micronutrients for plant growth, bulb quality Onion (Allium cepa) in NFT system Hydroponics. Study Design: Randomized Block design. Place Duration Study: The experiment was carried out 2022 at shadenet Department horticulture, Naini Agricultural Institute, SHUATS, Prayagraj. Methodology: conducted Design with 7+1 (Control) 3 replications. treatments were T0 Tap water, T1 (8.12ml NPK/Pl), T2 (9.37ml T3 (10.62ml T4 (11.87ml T5 (13.12ml T6 (14.37ml T7 (15.62ml NPK/Pl). From present investigation it is found that treatment )15.62ml NPK/Pl) to be best terms Plant length, Number leaves, diameter weight bulb, girth days maturity, Days flowering, average fresh weight, neck thickness sensory evaluation, TSS, ascorbic acid, dry matter content, moisture content cost benefit ratio. Results: current study indicates maximum growth yield observed Treatment 7
