Gendy, A. A. S.; I. E. Nasr El-Din and A. S. Antar.( 2009). Effect Of Irrigation, Potassium Application And Distance From Drain Line On Wheat Crop In Clay Soil.J. Agric. Res. KafrEl-Sheikh Univ., 35 (3) 897-908 (2009)
Abstract: Two field experiments were carried out at Sakha Agricultural Research Station. The field is provided by tile drains network spaced at 20 m with 1.2 m depth in order to study the effect of distances form drain line, potassium application and holding the last irrigation on yield and yield components of wheat crop. The experiments were conducted in a split-split-plot design. Results showed that:Decreasing distance from drain line L/2 to L/4 resulted in a significant increase in the dry matter at tillering and booting stages and grain yield at harvest. The values of dry matter at tillering, booting stages and grain yield near the drain were higher than that far from it by about 34, 139 and 53 kg/fed and 63, 123 and 65 kg/fed, for the first and the second seasons, respectively. Grain and straw yields significantly decreased by withholding the last irrigation by about 1.22 and 1.50 (ardab/fed.) and 1.17 and 0.55 (heml/fed.) in the first and second seasons, respectively.K-fertilization application realized favorable effect for yield and yield components of wheat in two seasons. The interaction between distance from drain line and K-fertilization was significant decrease under zero K-fertilization in the dry matter at tillering stage, while, it was significant at booting stage under conditions of with and without k-fertilization, but grain and straw yields were insignificant. Withholding the last irrigation resulted in a significant decreases with and without potassium in 1000 grain weight and grain yield. Dry matter at tillering and booting stage were significantly decreased with increasing the distance from drain line with both irrigation treatments. Also, the increase of distance from drain line and irrigation regime gave a decreases in 1000 grain weight, grain and straw yields.

Keywords: (drain line, potassium, irrigation regime, wheat crop, clay soil.)
