چکیده

The experiment was carried out in the green houses research station (B) in the College of Agriculture / University of Baghdad / Aljadrya campus during the spring season of 2016 to study the response of nitrogen fixing bacterial biofertilizers including Rhizobium phaseoli, Azotobacter chroococcum, and Azospirillum brasilense and molybdenum on growth and yield of green beans in The plastic house . The experiment was conducted according to the randomized complete block design (RCBD) with three replications each included 11 treatments represent the interactions between nitrogen fixing bacteria isolates, molybdenum solo application, molybdenum and bacteria isolates interactions, in addition to the recommended nitrogen application and control treatment. Results were analyzed using the least significant differences (LSD) test at 5% level of significance. Results showed T7 significantly increase N % in the pods ( 2.73 (%, Treatment included all bacteria isolates and Mo (T11) gave the most significant percentage of p in the pods (0.21%) and root nodular fresh weight of 2920.00 mg.plant-1 , treatment (T5) gave the highest K % in the pods (1.46% (, As for the T10, results showed significant concentration of Mo in the pods (0.63 ml.kg-1 ( , Moreover, T3 significantly increased percentage of carbohydrate (3.74%) , As for the T9, results showed significant percentage of Dry material 21.38% , T6 gave the most significant T.S.S (8.17 %) . solo treatment (T2) gave the highest concentration of Fe in the pods (55.58 ml.kg-1 (, root branches ( 11.56 branch. plant-1 ) , root dry weight (9.11 g. plant-1) , shoot branches per plant , leaf area and leaf chlorophyll concentration that reached 4.00 branch. plant-1 , 63.15 dm2. plant-1 and 210.97 mg.100g-1 fresh weight respectirely, weight of pods (9.76 g.pod-1) , and total production (633.74 Kg . house-1) with an area of 418.5 m2.
