Onion (Allium cepa L.), a member of Alliaceae family, is one of the most important commercial vegetable crops grown in almost all parts of the world and believed to be originated from Central Asia and Mediterranean region and commercially grown in China, India, U.S.A., erstwhile U.S.S.R., Japan, Spain, Turkey, Brazil, Egypt, etc. In the world, Onion crop is grown in about 5.30 million hectare area with an annual production of 88.48 million tons with productivity 16.70 tons per hectare. China stands first in the onion production (22.61 million tons from an area 1.03 million hectares area) in the world with productivity 21.85 tons per hectare, followed by India. In the world production of onion, India has second place after China. In the foreign exchange point of view, onion ranks first in vegetables. Yellow type onion constitutes a bulk (80%) of the world trade particularly in European market, red coloured constitutes 20% of the world trade, major share of the market being in the Asian countries.in this book, we get to know, how to grow a non-toxic and eco-friendly technique of farming of onion and the natural way for disease pest management.

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.
