Abstract: The field experiment was conducted to study the “Effect of Nutrients and Plant Growth Regulators on Growth, Yield, Quality and Storage Life of Onion (Allium cepa L.)” in loamy sand soils of the Research Farm, Rajasthan Agricultural Research Institute Durgapura (Jaipur, Rajasthan) during rabi season 2016-17 and 2017-18. The experiment consisted four nutrient combination (NP, NPK, NPKS and NPKSB) and four treatment were nutrient and plant growth regulators (Control, CaCl2 @ 0.5%, ethephon @ 3000 ppm and mepiquat chloride @ 750 ppm) under three curing methods (Field curing, curing under 60% shade and curing under poly tunnel) thereby making forty-eight treatment combinations tested in factorial randomized block design with three replications. Results indicated that economics of maximum net returns Rs 475439.31 /ha and Rs 466819.98 were recorded with combined application of NPKSB, mepiquat chloride along with field curing and NPKSB, mepiquat chloride along with 60% shade net curing during 2016-17 and 2017-18 respectively. Maximum B: C ratio 6.11 and 6.01 was recorded with combined application of NPKSB, mepiquat chloride along with 60% shade net curing during 2016-17 and 2017-18 respectively.
