Abstract
In Egypt ,many farmers have adopted large quantities of P-fertilization in planting their crops ,especially faba bean plant . Although, surveying literature indicated that P-application at high rates induce imbalance between macro and micro nutrients. For this reason, afield experiment was conducted in a private farm, Borg El-Nor at Aga District, Dakahlia Governorate., under alluvial soil during the winter season of 2014/2015 to determine the effect of high doses of phosphorus fertilizer in the presence or absence of Zn foliar application under inoculation or without inoculation and investigate the interactive effects on growth parameters ,nutrient content and yield of faba bean (Vicia faba L.) Sakha1 at flowering and harvest stages. The combined effects of phosphorus, Zinc and Rhizobium were investigated by combining four P levels (0,13.08,26.16 and 39.42 kg Pfed-1) and two spraying rate of Zn (0 and 100 ppm Zn). Also, each treatment was studied twice; once in the presence of strains inoculants at the rate of 400 g / fed and the other without inoculation .The experimental design was split split plot with three replicates. The results show that the application of 26.16 kg P fed-1 (P3) with the spraying of Zn under inoculation or without inoculation produced higher plant height , number of leaves, shoots fresh and dry weight, protein of grain , seed index and seed yield than that obtained for the control treatment. Moreover, increasing P-fertilization level to 39.34 kg P fed-1 with Zn spraying, under inoculation or without inoculation, resulted in significant decrease in all growth parameters except straw yield than the levels of 26.16 kg P fed-1 . Also, the interaction between all studied treatments significantly affected chemical constituents at the two studied stages.
