RESPONSE OF FABA BEAN TO LEVEL AND PLACEMENT METHODS OF POTASSIUM APPLE CATIONS IN SANDY SOIL AT NORTH SINAI
Applying K fertilizer into drip irrigation system is not routinely practiced for faba bean under desert conditions. Vegetative growth, seed and straw yield, K contents in tissues and soil as affected by application of K through drip irrigation system compared to side dressed application was studied under field experiment at EI- Maghara Research Station of Desert Research Center - North Sinai. The experimental treatments included 1) six levels of K (0, 30, 60, 90, 120,150) kg K20/fed. added each two weeks where all plots were drip irrigated and 2) two placement methods (fertigated and side dressed) were compared for growth and yield
characteristics. .
Increasing rates of K through drip irrigation system increased significantly plant height number of branches I plant, number of podsl plant and straw & seed yield I fed. where, the application of 120 kg K20/fed. produced the highest response. The adequate range of K content in faba bean tissues is ranging from about 2 to 3%. The repeated application of K through drip irrigation system was significantly more effective than side dressed application where considerable amount of K can be lost by leaching in sandy soil. Movement of K below drip irrigation system is expected if application is concentrated by applying the fertilizer to small volume of soil under drippers. An increasing necessity is encourage to introduce faba bean cropping with fertigated system under desert conditions of North Sinai.
