| Abstract | ||
| The study was carried out to investigate effect of Nitrogen and Potassium fertilizers on yield and yield components of cotton (Gossypium hirsutum L.) var. lachata . Field experiment was condected during summer season 2008 , at two location using (R.C.B.D) design with three replications while the Nitrogen fertilizer added at four levels(0, 320, 400, 480 ) kg urea /h. Potassium fertilizer (0, 240 , 360 , 480 ) kg K2SO4 /h, Nitrogen and Potassium fertilizer were added in two doses ,first one at sawing and the second half after Month of seedling stage . Data obtained in this investigation indicated by fallowing: Application of nitrogen and Potassium fertilizer resulte significant differences in yield and yield components in both locations ( number of bolls / plant , total number of bolls , mean weights of bolls , seed index , total yield of cotton seed , percentage of early ripening and net ginning except seed index in second location from Potassium fertilizers . the interaction between Nitrogen and Potassium fertilizers levels was significant in third level of nitrogen and potassium application resulted highest yield of cotton (2620, 45 and 3717,95 kg/h) in the first and second location respectively . | ||
