Abstract:
The onion (Nasik Red) field study, which comprised 10 different treatments laid out in a split plot design with three replications at ARS-SKRAU, Beechwal, Bikaner Zone Studies, clearly showed that application of inorganic fertilizer’s at N, K and S levels significantly increased all the growth, yield and quality characters viz. Shelf life, TSS, Allyl propyl disilphide of onion. Similarly, N levels of @ 80 kg N ha^-1 (soil application) + 20 kg N ha-1 (4 foliar sprays) produced the highest bulb yield (227.62 q ha^-1), closely followed by N2 (210.45 q ha^-1) and N fertilization @ 80 kg N ha^-1 (soil application) + 20 kg N ha^-1 (4 foliar sprays), which was significantly higher than control. Application of 80 kg N and K ha^-1 (soil application) + 20 kg (4 foliar sprays) and 40 kg sulphur ha^-1 produced a significantly superior crop, and this treatment combination was recommended for maximum bulb production of onion.
