Effects of Sole and Combined Application of Goat Manure and Urea Fertilizer on the Performance of Amaranth (Amaranthus cruentus,L.)

A field experiment was carried out at Federal College of Agriculture, Akure, Ondo State (Latitude 7108’N and Longitude 5015’E) Nigeria in 2015, to determine the effects of sole and combined application of goat manure and urea fertilizer on the performance of amaranth. The treatments applied were: Sole 6ton/ha goat manure, 6ton/ha goat manure + 50kg/ha urea fertilizer, 6ton/ha goat manure + 100kg/ha urea fertilizer, 6ton/ha goat manure + 150kg/ha urea fertilizer, sole 200kg/ha urea fertilizer and control (no treatment). Application of sole 6ton/ha goat manure, 6ton/ha goat manure + 50kg/ha urea, 6ton/ha goat manure + 100kg/ha urea and 6ton/ha goat manure + 150kg/ha urea compared with control increased marketable yield of amaranth by 43, 57.9, 58 and 60.8% respectively.  The use of goat manure at 6ton/ha with urea fertilizer reduces requirement mineral fertilizer to about 25%.
