Improving the growth traits and yield of several varieties of sesame by the effect of planting distances between the lines

Abstract

A field experiment was carried out using Design (RCBD) in the arrangement of split-plot design with three replications. The plants of the Hade variety outperformed significantly in giving the highest means for traits of plant height, number of branches per plant, number of capsules per plant, and seed yield. While Rafedain variety plants achieved the highest average weight of 1000 seeds, and Sumer variety plants took the least number of days to reach the 50% flowering stage, The highest mean of the plants planted at a distance of 80 cm between rows was in the traits of plant height and plant yield, while at a distance of 40 cm between the rows achieved the highest means of the traits of the number of branches, the number of capsules, and the weight of 1000 seeds. The highest average for interaction between plants of the Hade cultivar at a distance of 80 cm was in plant height and seed yield traits. Compared to other interactions, the highest mean for a distance of 40 cm for the number of capsules. Keywords: sesame, planting distances, growth, varieties (Sesamum indicum L.)
