Integrated nutrient management: A sustainable approach for onion production

Abstract

Onion is one of the most commercial vegetable which belongs to family Alliaceae. It is also used as spices and medicinal crop. Onion is classified as high value cash crop and have high domestic demand and good export potential. Being a shallow rooted and long duration crop nutrition play important role in its production. It require and often respond well to additional dose of fertilizers (organic, inorganic). Inorganic fertilizers are mainly used to obtain high yield. Long term use of these fertilizers adversely affect the soil fertility and also cause environment pollution. To maintain the sustainable production and soil health integrated nutrient approach should be used. Integrated use of organic and inorganic fertilizers improve the bulb size, quality and also increases the yield in comparison with the exclusive application of any one source of nutrient.
