 In: Samaru Journal of Agricultural Research v. 3, no. 1/2, p. 31-3888-042559Summary: Response of irrigated wheat to N, P and K fertilizers was evaluated at three different locations in the Nigerian savanna. Wheat responded significantly to applied N up to 50 kg/ha at Kaduna and 150 kg/ha at Hadejia. The low N requirement at Kaduna was due to high natural fertility of the alluvial soil where the zero (control) yield was quite high. Low yields and poor response of wheat to N at Bakura were a result of magnesium deficiency and possibly some trace element deficiency in the soil. It was shown that quadratic response curves based on a few points from a few trials overestimate the N requirement of wheat. The limited trials reported here indicate that
