Response of cotton to various doses of NPK fertilizers

Cotton is an economically important crop and experiments to determine its response to rates of fertilizers have always been an important part of research. Thus a field experiment was laid out to assess the yield performance of cotton under the fertilizer (NPK) treatments during 1997, 1998 and 1999 crop season. On an average, highest seed cotton yield of 2434 kg ha-1 was obtained when the crop was fertilized with 75, 50 and 50 kg ha-1 of N, P and K respectively followed by 100 nitrogen, 50 phosphorus and 50 potash kg ha-1 was produced from the control plot where no chemical fertilization was applied. The results reveal that balance use of above nutrient elements are essential for harvesting better yields.
