Abstract
The first experiment studied the response of snap beans to 50% of the recommended inorganic N fertilizer combined with some strains of rhizobium leguminosarum biovare phaseoli and 2Biofertile3. The combination between inorganic fertilizer and the mixed inoculum of biofertile plus and the multi-strain rhizobial inoculum supported maxima plant vegetative growth, green pods yield and pod NPK percentages. The second experiment dealt with the effect of biofertilization with effective strains of rhizobium leguminosarum biovare phaseoli and a rhizobacterial preparate 2Biofertile3 accompanied or not with one type of organic fertilizers 2Botanical-waste compost (Compost1) or animal botanical-waste compost (Compost 2)3 or inorganic fertilizer (N) 75% of the recommended doses i.e., 60, 60, 45 kg fed⁻¹ of NPK fertilizers respectively. The obtained results indicated that inorganic nitrogen fertilizer enhanced some measured plant growth parameters. plant-1 as branch numbers, leave number, leave area, root length. Biofertilization improved nodulation and significantly increased yield compared with uninoculated control. Maximum vegetative growth was scored of snap bean plants particularly those received mixed inocula of Biofertile plus and multi-strain rizobial inocula
