| Abstract | ||
| Two field trials were conducted at ismailia Agricultura’ Research Station ¡n 2001/2002 and 200212003 growing seasons to study the effect of foliar spray and seeds soaking application of 2% super-phosphate and 2% potassium sulphate (singly or in combination) on faba bean yield and its seed protein, phosphorus and potassium content under sprinkler ¡rrigation system in sandy soil. The obtained results indicated that: 1- The application of P and /or K as foliar spray or seeds soaking treatments induced significant increases ¡n seeds and straw yield of faba bean as well as seed protein, P and K contents during the two growing seasons compared with the control treatment. 2- Seed index (weight of 100 seeds) was not significantly affected by all studied treatments. 3-. Foliar application of 2% super-phosphate was the best treatment used for increasing the quantity and quality of faba bean yield, followed by the mixture of (2% P + 2% K) foliar spray treatment with no significant differences in most cases. 4- Under the same conditions, faba bean plants should be foliar sprayed 2 times (45 days after planting and 15 days later) with 2% super-phsphate singly or ¡n combination with 2% potassium sulphate with the addition of recommended soil fertilization. | ||
