Reverse all the legumes crops, the nitrogen (N) fertilizer requirement of snap bean plant is high, due to it is weak in the fixation of atmospheric N. Using organic fertilizers; chicken manure and biofertilizer, can serve as an alternative to use mineral N fertilizer. Two greenhouse experiments were carried out in factorial randomized complete block design with three replicates. Each experiment included eight treatments; four rates of chicken manure (CM) as a source of organic N; 0 (CM0), 50 (CM1), 100 (CM2) and 200 (CM3) kg N per ha applied singly or in combined with biofertilizer (Halex-2). The application of CM2, significantly, increased the number of leaves and branches, leaf area index and pods number per plant, as well as pods yield, dry mass and N uptake per ha compared with CM0. Moreover, inoculating seed of snap bean by biofertilizer significantly increased all studied parameters of snap bean plants. The dry matter and N uptake were mainly distributed in pods, followed by leaves, and stems. The pods yield of snap bean plants was highly positively correlated with the number of branches and leaves, leaf area index, flower clusters number, dry mass, number of green pods, pod weight and N uptake characters, orderly. Generally, the best significant vigorous of the growth and yield traits of snap bean plants, was achieved with the dual treatment of CM2 (100 kg N per ha) and inoculate the seed with biofertilizer, which considered as one of the effective agriculture practices in organic farming and environmentally safe procedure.
