Abstract
A study was carried out at Igboora, South-western Nigeria from 2010-2011 to examine the effect of sole use of poultry and pig manures and their fortification with N fertilizer on performance of maize. The treatments were poultry manure (P) 5 t/ha, Swine manure (S) 5 t/ha, P 2.5 t/ha + 0.2 t urea/ha, S 2.5 t/ha + 0.2 t urea/ha and control. Poultry manure was higher in nutrients than Swine manure. The manures significantly (P<0.05) increased growth parameters. Combined application of manure and urea gave highest values of yield components such as number of grains, grain weight, number and length of cobs, other effects were significant. The poultry manure at 2.5 t/ha + 0.2 t/ha urea gave highest values. Fortification of manures with urea enhanced crop growth. The study showed that poultry manure had an added advantage over swine manure in Soil restoration but both could effectively be used in combination with chemical fertilizers to improve soil productivity for maximum maize production in the region.
