Abstract: Two field experiments were laid out to assess the yield performance of cotton for four successive years i.e. 1997 to 2000 crop seasons by the application of NPK fertilizers each having three levels (50, 100 and 150). On an average, highest seedcotton yield of 2413 kg ha-1 was obtained when the crop was fertilized with 150, 50 and 50 kg ha-1f N, P and K respectively. The lowest yield of 1039 kg ha-1 was produced from the control plot where no chemical fertilization was applied. The seedcotton yield was further significantly increased with the application of boron and zinc when applied alone or in combination. The results revealed that balance use of macro as well as micro nutrient elements are essential for harvesting better yields.
