Effect of Zinc Application on available N, P, K and Zn content of Soil under Wheat Crop

Abstract: The present investigation was conducted during Rabi season of 2019. A pot experiment was conducted in net house with 12 treatments ; 6 zinc levels (0,10,20,30,40,50 kg Zn / ha) as soil application and 6 levels of zinc (0,10,20,30,40,50 kg / ha) as soil application + 0.5 % foliar application. Standard methods of observation, analysis of soil and plant samples and appropriate statistical methods for the analysis of data were used. Soil pH, EC, Organic C, available N, P, K and Zn content in soil were analyzed. It was observed that available nitrogen, phosphorous and potassium content of soil were not affected by zinc application but zinc content was enhanced by zinc levels.
