Improving nutrient efficiency of soil using urea coats by mustard byproducts in wheat

Abstract

Urea applied to soil was leached out or vaporize to an extent of 60%, which can be reduced by nitrification inhibitors. The study was conducted to know the byproduct utilization of mustard as urea coating material in turn studied soil properties and additional effect on weeds in wheat. It was found that addition of botanical byproducts like mustard and karanj had increased the N (2.33%), P (0.14%) and K (1.21%) content. However, each nutrient enhancement was different in different products. N content recorded highest in coat with mustard and karanj (2.33%), P content in coat with mustard byproduct (0.16%) and K content recorded highest in coat neem oil and karanj byproduct (2.30%). The coated urea also recorded to enhance the organic matter content ranged from 1.21 to 2.30%. Per cent organic carbon was highest in coat with neem oil and karanj byproduct (1.03%). The application of urea coated with botanical byproducts and neem oils has an influence on weed, Eragrotis tremulo. The least weeds were observed in urea coated with mustard byproduct (26.60 weeds per plot).
