In field trials at Sakha in 1980-1, cotton Giza 75 was grown at hill spacings of 15, 20, 25 or 30 cm and given 40, 60 or 80 kg N/feddan. Seed cotton yields increased with increasing N rate in 1981 from 6.92 to 7.62 kentars/feddan but showed no trend in 1980. Boll wt. was not affected by N rate or hill spacings. Seed cotton yields increased with decreasing hill spacing in both yr. to max. of 9.78 and 8.18 kentars/feddan at the 15 cm spacing in 1980 and 1981, resp.
