H. 8200038A field experiment was laid out to assess the yield performance of two cultivars under ten fertilizer (NPK) treatments during 1992, 1993 and 1994 crop seasons at CRS, Ghotki Sindh. On an average, highest seed cotton yield of 2062 kg ha1 was obtained when the crop was fertilized with 112, 56 and 50 kg ha1 of N, P and K respectively followed by 112 nitrogen, zero phosphorus and 50 potash kg ha1 where seed cotton yield of 1933 kg ha1 was obtained. The lowest yield of 1283 kg ha1 was produced from the control plot where no chemical fertilization was done. The highest yielding variety GH-3 produced 1751 kg ha1 seed cotton followed by Shaheen (1657 kg ha1).]]>Colakoglu, H.,19801239Khan, M.A., A.W. Soomro, R.U. Khan and A.S.
