Abstract

A pot experiment was carried out in 2015/2016 to study the role of organic and bio-fertilizers in the validity of mineral phosphate fertilizers and their effect on the beans grown in clay soil. The obtained results could be summarized as follows: There was a significant increase in the mean values of plant height, seed yield, the weight of 100 seeds and crude protein due to phosphorus fertilizers solely or in combination with bio and organic fertilization compared with the control. In addition, the mean values of N, P, K, Fe, Zn and Mn concentrations in the straw and seeds of faba bean plant after harvest stage were significantly increased. Using organic and biofertilizers coupled with phosphate rock or super phosphate increase the availability of plant nutrients and its productivity and reduces the soil pollution resulted from mineral fertilizers.
