MagsiM. R. 9200039Cotton 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 ten fertilizer (NPK) treatments during 1997, 1998 and 1999 crop seasons. On an average, highest seedcotton yield of 2434 kg ha1 was obtained when the crop was fertilized with 75, 50 and 50 kg ha1 of N, P and K respectively followed by 100 nitrogen, 50 phosphorus and 50 potash kg ha1 where seedcotton yield of 2403 kg ha1 was obtained. The lowest yield of 1053 kg ha1 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.]]>Bisson, P., M. Cretenet and E.
