Abstract
Phosphorus and potassium supply to leguminous crops is necessary especially at the flowering and setting stages. A 2-year field experiment was carried out at Ismailia Agricultural Research Station in 1994/ 95 and 1995/96 growing seasons to evaluate the effect of foliar application of the supernatant of soaked Ca-superphosphate (SP) and K-sulphate (KS) both at the rate of 5 kg/fed., (5 kg Sp + 5 kg KS) /fed. (10 kg SP + 5kg KS) / fed. or (5kg SP+10 kg KS)/fed. on yield and its components of lentil and lupin as well as seed contents of protein, phosphorus and potassium. Foliar spray with the solutions of SP at the rate of 5 kg/fed. or the mixture of 10 kg SP+ 5 kg KS/fed. induced significant increases in yield and yield components of both crops during the two growing seasons compared to the control, except the lupin straw yield which was not significantly affected by all studied treatments. Foliar application of 10 kg SP + 5 KgKS/fed. was superior to 5 kg SP/fed. in most cases with no significant differences. Both lentil and lupin plants were not significantly affected by the other treatments except the straw yield and seed potassium content of lentil which showed significant increases due to foliar application of KS (5 kg/fed.) and 5 kg SP + 10 kg KS/fed. Seed contents of protein and phosphorus were not significantly affected by the studied treatments.
