Abstract:
Field trials were conducted during the rainy seasons of 2005, 2006 and 2007 to study the contributions of some yield attributes to the seed yield of sesame. The experiments consisted of four levels of poultry manure (0, 5.0, 10.0 and 15.0 t ha-1), three levels of nitrogen in the form of urea (0, 60 and 120 kg N ha-1 ) and three levels of phosphorus in the form of single super phosphate (0, 13.2 and 26.4 kg P ha-1). The thirty six treatments were laid out in a split-plot design with three replications. The factorial combination of N and P were assigned to the main plot while poultry manure was assigned to the sub-plot. All yield attributes measured (number of capsules plant-1, capsule yield plant-1, seed yield plant-1 and seed oil-content), correlated positively and significantly (p = 0.01) with the yield throughout the years of experimentation and the mean of the three years. Path coefficient analysis revealed that the highest contribution among the yield components was made by seed yield per plant (0.5866a) followed by number of capsule per plant, capsule yield plant and seed oil content. The combined effect of two factors on the yield was observed to be inconsistent when the individual year is being considered but when the three year data was combined, the combined contribution of number of capsules per plant and seed yield per plant was found to be the highest (0.3989). The highest percent contribution to seed yield was made by and via seed yield per plant (34.4042 and 21.2104%) when the data is combined. Seed yield plant-1 should therefore, be considered as the most important traits in the determination of seed yield per unit area and selection of parents.
