Influence of Organic and Inorganic Nutrient Sources on the Yield and Uptake of Major Nutrients in Soybean

A field experiment was conducted to study the effect of different organic sources of nitrogen with inorganic fertilizers on crop yield, yield attributes and uptake of major plant nutrients in the soya bean-maize cropping system. The highest soybean yield of 12.9qt-1 was obtained with the application of 75% of the recommended dose of nitrogen along with 100% recommended dose of phosphorus (P)& and potassium (K) through inorganic fertilizers+25% recommended dose of nitrogen through vermicompost and the lowest values of all the parameters were obtained from the control treatment. The uptake of nitrogen (N), P&K increased with treatments that received integrated use of organic manures in combination with the recommended dose of nutrients.
