Effect of Different Quantities of Irrigation Water on Growth and Yield of Wheat (Tritcum aestivum L.)

Abstract

A study was conducted in the Demonstration Farm of the Faculty of Agriculture, University of Khartoum at Shambat area for two successive seasons 1999/2000 and 2000/200. The objectives were to study the effects of the quantity of irrigation water and varieties on wheat (Triticum aestivum L.) growth and yield. The different water amount treatments used were 300, 400, 500 and 600 mm. The irrigation treatments were calculated through calibration of the pump, using a stop watch. The varieties of wheat used were: El Neilein, Condor and Deibira. Data collected included crop growth and yield parameters of wheat. A split plot design was adopted for analyzing the parameters, with the irrigation treatments as main plots and the varieties as sub-plots. Differences in season 1999/2000 were due in wheat to uncontrollable weather conditions. Irrigation water amount significantly affected yield, the high yields were obtained from 500 and 600 mm, while the lowest was recorded by the 300 mm treatment. There were slight difference effect on growth and yield components except El Neilein which showed high grain yield with high amount of water (500 and 600 mm). Also there were differences in plant height between the two seasons, this could be attributed to the high temperatures that prevailed in the 1999/2000 season
