Abstract

Due to the absence of an appropriate plant spacing that related to sesame branching habit in the study area; an experiment was conducted to evaluate the effects of row spacing on yield, oil and protein content of sesame varieties in randomized complete block design with three replications.  The experiment consisted of five sesame varieties (S, T-85, Argane, Mehado-80, Serkamo) and four rows spacing (30, 40, 50, 60cm). The results showed that the difference between varieties were significant at 5% probability level in all traits except number of capsules plant-1 and number of seeds capsule-1. Serkamo variety had the highest 1000- weight seed (3.52 g), seed yield (205.8 kg ha-1), oil yield (94.0 kg ha-1), protein yield (43.9 kg ha-1) and number of seeds capsule-1 (61.67). Except 1000- weight seed, all traits were affected at 5% probability level by row spacing. Highest seed yield (205.3 kg ha-1), oil yield (96.4 kg ha-1), protein contents (22.29 %) and protein yield (45.8 kg ha-1) were obtained at 40cm row spacing whereas number of capsules plant-1 (99.65) and number of seeds capsule-1 (63.34) were at 60cm row spacing. Interaction effect of variety x row spacing was affected number of capsules plant-1, seed yield, oil yield and protein yield. The highest seed yield (242.3 kg ha-1), oil yield (112.3 kg ha-1) and protein yield (53.8 kg ha-1) was obtained from Sekamo variety at 30cm row spacing.
