Performance of In-situ Rain Water Harvesting on Yield of Grain Sorghum in Gradud Soil of North Kordofan

Shortage of rainfall is one of the most severe stresses faced the crop productivity in the Sudan. The continued decrease in productivity of the crops in North Kordofan resulting from rainfall decline and drought. These necessitate application of micro-catchment water harvest methods and techniques to catch small amount of rainfall available, in order to increase crop productivity. Afield experiment was conducted during two consecutive seasons, under rain fed condition in gradud soil of North Kordofan State. The aim of this study was to investigate the effect of in-situ water harvesting technique on growth and yield of four sorghum (Sorghum bicolor L. moench) cultivars. The Strip Plot Design with four replications was used. The results showed that in-situ water harvesting treatment had significant effect on the most parameters measured. It has increased the number of seeds per panicle, 100- seed weight, panicle weight and preform a highest seed yield (t ha-1). In addition, the results revealed that the improved cultivar (Yourwasha) performed the best for most of the characters measured. It revealed a highest 100- seeds weight, seeds yield per plant and the final seed yield (approximately 3.5 t ha-1).
