Onion Research Work

Onion is a sulphur loving plant and the latter is required much for proper growth and yield of earlier. Role of sulphur is particularly important in the nutrition of onion as it is constituent of allin, cycloallin and thiopropanol. The productivity of onion in Madhya Pradesh is very low. Among various factors responsible for the low yield of onion, inadequate and imbalanced use of fertilizer as well as no use of secondary and micronutrients (sulphur and boron) are the major factors. Keeping in view, the present investigation entitled "Effect of sulphur and boron on growth and yield of onion (Allium cepa L.)" was conducted during Rabi season of 2017-18 at the horticulture nursery, College of Agriculture, Gwalior with the following objectives:1. To assess the influence of sulphur and boron on morphological and post-harvest parameters of onion;2. To find out the combined effect of sulphur and boron on growth and yield of onion;3. To find out the optimum dose of sulphur and boron for maximizing the bulb yield of onion and4. To work out the economics of different treatments.
