Effects of Seeding Rate on the Yield Components of an Enhanced Rice Cultivar (DTPMFe+) Oryza sativa Linn.

M. Oziegbe and J.O. Faluyi    

Abstract: This study was conducted to investigate the comparative effects of seeding rates of two plants per hill and one plant, per hill on the yield components of DTPMFE+, an enhanced rice cultivar. The design of the field experiment was Randomized Complete Block with replications on a fenced plot of 18.00x4.00 m. A potted experiment was carried out in ten four litre buckets. At maturity panicle characteristics and number of tillers of plants randomly selected were measured. In the field population, there was no significant difference in total number of spikelets, number and length of primary branches, number and length of secondary branches, panicle length, panicle density and number of tillers. Significant differences were observed in grain length and grain width one plant per hill had higher values than two plants per hill. In the potted population, there was significant difference in total number of spikelets, length of primary branches, number and length of secondary branches, number and length of primary branches and panicle length; one plant per hill still showed higher values. Two plants per hill could not influence the yield components for better yield.
