| dc.description.abstract | Two field experiments were conducted at the C.S.I.R Crops Research Institute Rice Research field at Nobewam during the 2014 and 2015 growing seasons. The 2014 experiment was conducted in the minor season to evaluate the effect of age of seedling transplants on the growth and yield of lowland rice. The 2015 experiment was also conducted in the major season to evaluate the best top dressing time for urea application in lowland rice. Both experiments were laid out in the Randomized Complete Block Design with three replications each. Seedlings were transplanted in the 2014 experiment at 14, 21, 28, 35 and 42 days after nursery. In the 2015 experiments all plots received NPK fertilizer at the rate of 40kg ha-1 at 2 weeks after planting. Urea fertilizer was top dressed at 90kg/ha at various split times and concentrations. All cultural practices were carried out at the right times. Data collected included plant height, number of tillers, number of leaves, number of spikelets per particle, mean seed weight and grain yield. The results showed that the best transplanting time was 14 days, and that beyond 21 days growth, tiller production, grain weight and grain yield decreased. The 2015 experiment showed that although split urea application showed greater growth in rice, mean grain weight and total grain yield were greater when urea was top-dressed in a single dose of 90kg N/ha at 2weeks after transplanting. | en_US |
