Abstract: An experimental set up comprising of organic, primary, secondary and micro-nutrient combinations [FYM (15 t/ha), NPK (125:100:100 kg/ha), sulphur (40 kg/ha), boron (0.2%) and zinc (0.05%)] were tried out to study the field response of onion cv. Sukhsagar under Red and lateritic zones of West Bengal, India. Results revealed that additional application of Sulfur, Boron and Zinc alone or in combinations with FYM and recommended dose of fertilizer increased the plant height, neck diameter and bulb diameters in onion. Maximum bulb weight and bulb was recorded with the application of FYM, NPK and sulphur with or without addition of boron and zinc. For quality parameters like dry weight, total and reducing sugar and TSS, no definite trend was noticed for nutrient application in onion. Overall interpretation of the gathered data suggests that soil application of FYM @ 15 t/ha and NPK @125:100:100 kg/ha along with sulphur 40 kg/ha &/or foliar application of B (0.2%) &/or Zn (0.05%) twice at 30 and 50 days after transplanting increases onion bulb yield.
