Intervention effect Gypsum at 30 kg/ha gave the highest bulb yield, 245.34 q/ha.
Intervention effect Gypsum at 30 kg/ha gave the highest benefit cost ratio, 2.43.
Intervention effect Gypsum at 30 kg/ha gave relatively less physiological weight loss, 20.34%.
Intervention effect Gypsum at 30 kg/ha gave relatively less rotting, 8.32%.
Intervention effect Gypsum at 30 kg/ha gave relatively less sprouting, 15.24%.
Intervention effect The response to 30 kg/ha gypsum was not significantly different from 45 kg/ha sulphur.
Intervention effect Onion bulbs under 30 kg gypsum/ha had maximum uptake of nitrogen, phosphorus, potassium and sulphur.
Recommendation The authors recommend gypsum at 30 kg/ha for onion nutritional status and economic return in sandy loam soil.
