Integrated nutrient management practices in summer groundnut

Abstract

Groundnut is an important oilseed crop of Odisha grown in Kharif, Rabi and summer season and average yield is well below the national average. It is an exhaustive crop and reported to remove higher quantity of nutrients from the soil than a normal rice crop does. This problem is more visualized with increased use of high yielding genotypes across the state and country. Use of high analysis fertilizers containing no micronutrients, little or no use of organic manure and imbalance and injudicious application of nutrient fertilizer create problem of multi nutrient deficiencies which result in low yield. Information on yield reduction due to omission of any nutrient and their interaction effect is very much limited. Keeping in view the above facts, the present investigation was aimed to maximize the yield in groundnut through integrated nutrient management practices.
