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

Abstract

Selection of optimum fertilizers is very important for the production of a crop. Micronutrients play various important roles in plants for their proper growth and development. In the present study, the effects of some micronutrients viz. Zinc (Zn), Sulphur (S) and Manganese (Mn) was observed on growth and yield of Onion (Allium cepa L. cv. Nasik Red). These micronutrients were applied in soil in different combinations alone and with combination of N, P, and K. Bulb weight, diameter of bulb, neck thickness of bulb, and bulb yield were observed in the produced plants and economic importance of treated plants were calculated. The result revealed that presence of all the micronutrients along with N, P, and K in soil enhanced all the above-mentioned factors in the plants when compared to control plants significantly. Treated plants were also found more economic to farmers.
