Abstract

Growth and yield response of sweet maize ( Zea mays L. saccharata Strut.) to rates of poultry manure (PM) and NPK 20-10-10 fertilizer was studied under field condition in 2010 late growing season in Calabar, a humid forest agro ecology of south eastern Nigeria. Treatments comprised of three rates of PM (0, 5 and 10t/ha), factorially combined with four rates of NPK (0, 200, 400 and 600 kg/ha) and arranged into a randomized complete block design with three replications. Application of PM at the highest rate significantly increased plant height, number of leaves/plant, number of cobs/plant, unhusked and dehusked green cob yields and also hastened days to 50% tasselling. The highest rates of PM and NPK maximized leaf area index (LAI), number of grains/cob and harvest index (HI) whereas total dry matter (TDM), weight of grains/cob, cob yield/ha and total grain yield peaked at 10t/ha PM and 400kg/ha NPK fertilizer. The 10t/ha PM rate and 400kg/ha NPK increased TDM by 43 and 91% and total grain yield by 101 and 34% respectively, compared with the control. Poultry manure at 10t/ha in combination with 400kg/ha NPK fertilizer out-yielded other treatments in terms of biomass yield, cob yield/ha, harvest index and total grain yield.
