POTASSIUM UPTAKE EFFICIENCY OF COTTON CROP AS AFFECTED BY SOIL TYPE AND K FERTILIZER LEVELS
Soil. Dept., Fac. of Agric., Mansoura University, Egypt
Abstract
A pot experiment was carried out to study potassium uptake efficiency for cotton crop as affected by soil type (clay loam soil and sandy loam soil), and K fertilizer levels under the conditions of El-Sharkia Governorate during 2004 season. This work ended to many positive results:
Potassium additions tended to increase the dry weight of cotton plants (g pot-1) high significantly during different growth stages.
Values of potassium uptake (mg pot-1) were increased in clay loam soil more than sandy loam soil. The highest values were at harvest and at the fertilizer level K2 compared with control treatment.
Increasing potassium fertilizer level led to increasing the yield. Data reveal the relation and the correlation between the potassium, soil type, the yield and the crop yield through the equations.
