Abstract

Aim: The aim of this study was to assess the performance of sesame crop (Plant Height , Moisture Content , No Capsule/ plant, Seed weight , and Mean Yield)under three water harvesting techniques(tied furrows, semi-circular bund and contour basin "traditional terraces") assigned to the main plots, and three watering practices (fully-irrigated, supplemental irrigation and rain fed systems) assigned to sub-plot.

Materials and Methods: Water was applied from a farm reservoir "Hafir" to the field by a mobile gun sprinkler. Data on plant height (cm), number of capsules per plant, seed weight (mg), and seed yield (kg/ha) were recorded.

Results: Analysis of variance indicated that both water harvesting techniques and watering application practices significantly (p<0.05) improved sesame growth attributes and grain yield. The mean seed yield obtained from supplemental irrigated treatments (467.5 Kg/ha) is significantly higher by 29% than yield obtained with rain fed system (361.3 Kg/ha) and equivalent to 72% of that obtained with full irrigation (644.3 Kg/ha).

Conclusion: It was concluded that application of supplementary irrigation in congestion with semi-circular bund could be an important climate change adaptation strategy in areas with variable rain amount and bad distribution.
