Management of plant nutrients for enhancing oil content in oilseed crops - A review

Abstract

Nutrient management is an important activity in crop production. Most of the cases, organic and inorganic sources of
 plant nutrients are advocated for enhancing the nutrient concentration in soil and uptake by plant roots. However, soil
 physico-chemical properties greatly influenced by the availability of plant nutrients in soil solution.  Addition of organic
 matter through FYM, crop residues, green manuring enhanced the fertilizer use efficiency in most of the soils.  In most
 of the oilseed crops, nutrient management is an important task for improving the soil health parameters and sustainable
 crop yield. Oilseed crops majorly require nitrogen, phosphorus, potassium, sulfur, calcium, zinc and boron based on the
 soil test values. Other advance agronomic practices also  carried out to enhance the fertilizer use efficiency in oilseed
 over a period of time. Integrated use of chemical fertilizers with organic sources improved the soil physico-chemical,
 biological properties in soil  in a long run. Soil test based management of plant nutrients are advocating for sustainable
 oilseed production without compromising the soil and environmental health. In this review, the major plant nutrients role
 in oilseed production and their efficient management through the best management practices are discussed. It also
 indicated that the climatic factors also influence the efficiency of plant nutrients during the crop growth. Increasing
 awareness about the balance application of plant nutrients in oilseed crops is a key activity in nutrient management.
