Abstract

Two field experiment were carried in the winter seasons of 2006/2007 and 2007/2008. To study the interaction effect of P and K fertilization on growth, yield, nodules formation, proteins%, phytic acid% and nutrients uptake of faba bean plants grown under salt affected soils. The experimental soils used represent nonsaline (2.36 dS·m−1 EC) and saline (5.6 dS·m−1 EC). The effect of three P levels (0%, 50%, 75%, 100% from recommended dose as superphosphate 15.5% P2O5), the foliar K levels (0%, 1%, 2% from recommended dose in the form of potassium sulphate 48% K2O) and seeds (Skha1 cultivar) before sown inoculated by ryzobium. A split-split plot design with four replicates were used. The main findings could be summarized as follows: 1) Saline conditions decreased the plant height, No of branches/plant, seed weight/plant, 100-seed weight, seed yield (ardab/fed.), straw yield (ton/fed.) No. of nodules/plant, protein % and nutrients uptake (N, P, K Kg·fed−1) in both seasons. And the heights results were obtained from normal soils, while saline conditions increased significantly phytic acid%. 2) Adding 2% K(foliar) significantly increased all studied factors under study in both seasons except phytic acid%, where adding 1%K(foliar) casing rising values of phytic acid in both seasons. 3) 100% P treatment gave the highly significant increase in all factors in both seasons. 4) The interaction between all studied treatments on faba bean characteristics under study had a significant effect, which, the best results were obtained from the interactions of normal soils with 2% K and 100% P treatment at all studied factors except the interaction of saline soils with 0% K and 100% P gave the highest results for phytic acid%. 5) It can be noticed that, ryzobium can not act their roles well in nodules formation under saline conditions.
