ABSTRACT
Yield is a quantitative trait, controlled by polygenes and highly affected by environment. Foliar application of nitrogen constitute the environment believed to greatly influence the contribution of different attributes to yield when applied at different clusters. The experiment was laid out in a randomized complete block design using soybean TGX1440-E variety in a plot size of 2m x 2m, replicated three times to investigate the yield response dynamics. Nine clusters; R0, R1R2, R1R2R3, R2R3, R2R3R4, R3R4, R3R4R5, R4R5, R4R5R6 of different vegetative stages of development were adopted as treatments, urea was dissolved in water and applied. Correlation to establish the relationship of the yield components to the yield was also carried out. Significant differences were observed for all the traits at 5% probability level and treatment stage R4R5 presented the highest grain yield of 1965.6Kg/ha. Yield was positively correlated with hundred seed weight, number of seeds per pod and number of pods per plant. Cluster stage R4R5 may be adopted as most appropriate for N-application especially when foliarly applied.
