【 摘 要 】

Trial was carried out at Federal University of Agriculture, Abeokuta, Nigeria between 2010 and 2012 to determine response of lowland rice-ratooned rice-fluted pumpkin sequence to fertilizer. Experiment was laid out in Randomized Complete Block Design arranged in split-split plot in three replicates. Three rice genotypes constituted the main treatments sown in May and harvested in August. Split fertilizers application constituted sub-plot treatments were 90:45:45 (single dose), 45:22.5:22.5 & 45:22.5:22.5 (1:1), 30:15:15 & 60:30:30 (1:2) and 60:30:30 & 30:15:15 (2:1) NPK ha -1 at tillering and heading. N-fertilizer rates were  sub-sub plot treatment and applied to ratooned ‘NERICA L-42’ had the tallest plants compare to others. ‘Ofada’ had the lowest number of days to 50 % flowering for main and ratooned rice, while ‘NERICA L-42’ had the highest number of days to 50 % heading. ‘NERICA L-41’ variety had the highest grain yield in main and ratooned rice. Based on this study, ‘NERICA L-41’ plus its ratooned rice obtained from single dose NPK and zero N-fertilizer plots produced grain yield of 4.69 t ha -1 .
