Abstract:
To enhance productivity and food safety Indian Agriculture become more mechanized and science based by using nutrients, plant growth regulators and curing are among of them; These treatment are quicker impact on yield as well as quality of the crops. 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 randomized block design with three replications. Results indicated that application of NPKSB and mepiquat chloride@750 ppm significantly higher yield and quality attributes of onion over other treatment. The result also indicated the field curing significantly minimized the neck thickness and increased total soluble solids over poly tunnel curing and 60% shade net curing.
