Abstract
A field experiment was conducted during the 2009 wet season at two locations. Institute for Agr icultural Research Farm, Samaru (11 011’N, 07 0 38’E, 686 m above sea level) in the Northern Guinea Savannah ecological zone; and Irrigation Research Station of the Institute for Agricultural Research Kadawa (11 039’N, 08 0 027’E, 500m above sea level), in the Sudan Savannah ecological zone of Nigeria, to study the response of grain amaranth ( Amaranthus cruentus L.) to nitrogen fertilizer and farmyard manure. The treatments consisted of four rates of nitrogen (0, 50, 100 and 150 kg N ha -1 ) and three rates of farmyard manure (0, 4 and 8 t ha -1) arranged in a randomized complete block design and replicated three times. Nitrogen at the rate of 50 kg N ha -1 and farmyard manure at the rate of 4 t ha -1 respectively significantly increased plant height, plant dry weight, leaf area index, and crop growth rate but the total grain yield of the crop was not affected by the treatments in both locations. Application of nitrogen fertilizer in the absence of farmyard manure or vice versa which was statistically similar to application of 50 kg nitrogen fertilizer + 4 t ha -1 farmyard manure, and each produced significant growth responses. Therefore, application of farmyard manure at the rate of 4 t ha -1 in the absence of nitrogen fertilizer gave the optimum grain yield of amaranth.
