RESPONSE OF SESAME YIELD (SESAMUM INDICUM L.) CHARACTERS AND ITS COMPONENTS TO SOME AGRICULTURAL TREATMENTS

Abstract

One field experiment was carried out at the farm of Nasser's Faculty of Agricultural Sciences, the University of Aden in Lahej governorate during the two seasons 2011 and 2012 to study the response of sesame (Sesamum indicum L.) cultivar (Balady Red) to sowing dates, Nitrogen levels and plant density on growth, yield and its components characters and its interactions.

1. It could be concluded from this study that sowing dates had a significant effect on all yield and components characters. The highest values of all yield and its components characters were obtained from the early sowing date (15 August) during the two seasons.
2. Increasing nitrogen levels up to (160 kg N / hectare) significantly increased all yield and components characters during the two seasons.
3. Increasing plant density up to (250000 plant/hectare) gave a significant increase in seed yield/hectare, oil yield/hectare, and yield of crude protein/hectare.
4. Plant density up to (133333 plant/hectare) increased significantly the number of capsules/plant, seed index, seed yield/plant, seed oil content %, and seed crude protein content %.
5. Plant density up to (222222 plant/hectare) increased significantly seed crude protein content % and crude protein yield (Mt/hectare).
