Effects of Zinc, Manganese, and Sulphur on the Growth and Quality of Onion (Allium cepa L.) cv. Nasik Red

Abstract

Optimistic and sustainable supply of nutrients to soil affects crop productivity and crop quality. In the present investigation, effects of Zinc (Zn), Sulphur (S), and Manganese (Mn) was observed on growth and quality attributes of onion (Allium cepa L. cv. NasikRed), belongs to family Alliaceae. For this, micronutrients were applied to soil in 8 combinations including 1 control (having no micronutrient). soil application of micronutrients ZnSO 4@ 10 kg/ha + CuSO 4 10 kg/ha + MnSO 4 @ 10 kg/ha in combination with 50 kg N, 40 kg P 2 O 5 and 40 kg K 2 O per hectare before transplanting the onion crop is the most beneficial treatment for obtaining higher vegetative growth and quality of onion bulbs resulted high net income and maximum benefit of per rupee invested. However, for low input technology soil application of ZnSO 4 @ 10kg/ha + recommended dose of NPK can also be followed.
