OLUJIDE, M. G. and O. I. OLADELE, 2007. Economics of Amaranthus production under different NPK fertilizer regimes. Bulg. J. Agric. Sci., 13: 225-229
This paper examined the economics of Amaranthus production under different NPK fertilizers regimes. This is predicated on the fact that the increasing production of vegetables among farmers necessitates the need for optimum use inputs for increased production. The main objective of this study is to examine the gross margin analysis of the different level of N.P.K. (15:15:15) fertilizer on the yield of Amaranthus hybrids and specifically the yield of Amaranthus hybrids under different level of N.P.K. (15:15:15) fertilizer was determined. The experiment was conducted at the school farm of Lagos State Polytechnic Ikorodu campus Lagos State. The experimental site is located in the tropical rain forest zone of Nigeria. The experiment design was randomized complete block design replicated three times. The result of the analysis shows that the revenue realized from the sale of Amaranthus hybrids followed the trend of quantities of was realized from treatment two with the sum of N564.50k while treatment one with the sum of N372.60k and treatment three which is the control having the lowest revenue of N280.80k. The average yield of treatments 1, 2 and 3 are 24.84 kg, 37.64 kg and 18.72 kg respectively which means that the availability of nutrients to each treatment differ in terms of quantity, although the nutrients requirement are the same for the three treatments. Treatment 2 has the highest gross margin of N303.40. The study recommends that the drilling method of planting be adopted, to facilitate easy application of fertilizer for maximum utilization by the crop.
