Abstract

A field investigation entitled “Effect of Nutrients and Plant Growth Regulators on Growth, Yield, Quality and Storage Life of Onion (Allium cepa L.)” was carried out at Research Farm, RARI, Durgapura (Jaipur, Rajasthan) during Rabi season 2016-17 and 2017-18. Results revealed that application of N4 and G4 notably higher yield parameters of onion over other treatments. The result also indicated the field curing considerably minimized the neck thickness and increased TSS over poly tunnel curing and curing under 60 % shade net curing. The economics of maximum net returns Rs 475439.31 /ha and Rs 466819.98 /ha were recorded with combined application of NPKSB, mepiquat chloride along with field curing (N4G4C1) and NPKSB, mepiquat chloride along with 60% shade net curing (N4G4C2) during 2016-17 and 2017-18 respectively. Maximum B: C ratio 6.11 and 6.01 was recorded with combined application of N4G4C2 treatment during 2016-17 and 2017-18 respectively.

Keywords

B: C ratio, nutrients onion, yield, plant growth regulators, and net returns.

Conclusion

Based on the results, it is concluded that application of N4G4 (N100: P50: K150: S45: B1 + mepiquat chloride @ 750 ppm) was considered as the best treatment in respect to obtain significantly higher total bulb yield (465.56 q/ha) as well as marketable bulb yield (435 q/ha) in onion crop. This treatment also gave significantly higher net returns (` 461114.98/ha) and B: C ratio (5.96:1).
