Title: Effect of Water Quantity and Irrigation Intervals on Vegetative Growth and Yield Of Black Cumin (Nigella Sativa L.)
Author: Elsafi, Higran Hamid
Abstract: This study was carried out at the Demonstration Farm of the Department of Horticulture, Faculty of Agriculture, University of Khartoum, Sudan, during the season of 2000/2001 to investigate the effect of irrigation quantity and intervals on growth, yields and oil content, of the black cumin (Nigella sativa) so as to determine the optimum water quantity and interval under the prevailing environmental conditions of Khartoum State. The different treatments were arranged in split plot design. The different treatments included three amounts of water per season 400 mm, 500 mm and 600 mm and three irrigation intervals 7, 10 and 14 days. Data collected for vegetative and reproductive growth included plant height, number of branches, dry matter, number of pods/plant, number of mature pods/plant, number of seeds/pod, 1000 seeds weight, seed yield (ton/hectare) and oil content of the seed. The results showed considerable variation in growth and seed yield of the black cumin. There were no significant differences among the interaction between the water quantities and intervals. The results indicated that the vegetative growth was affected significantly by irrigation intervals, the lowest amount of water gave the highest value of vegetative growth. The continuous 14 days irrigation intervals had resulted in significant increase in the vegetative growth and yield components. The dry matter content was affected significantly by the amount of water, while there are no significant effect on number of pods. The number of seeds per pods was not affected by water quantities and intervals. Oil content of seeds was affected significantly by irrigation treatments, high amount of oil was obtained from the 4 00mm amount of water and 14 days irrigation intervals.
