Effect of Bio Fertilization and Boron Spraying on Growth and Green Pod Yield of Three Broad Bean (Vicia faba L.)

Abstract

Abstract The experiment was conducted in one of the fields of the Department of Horticulture and Landscape Engineering, College of Agriculture and Forestry - University of Mosul during the winter season 2019-2020 to study the effect of three factors: three cultivars of broad bean (Histal, Fava da orto, and Luz de otono) and the bacterial biofertilizer (Bacillus subtillis) at two concentrations (without spraying and 1 ml L1) and spraying with boron at three concentrations (without adding and 30 and 60 mg L1) within a randomized complete block design (RCBD) with three replicates. The results showed that the Histal cultivar gave the highest significant values in the number of branches per plant and the leaf area of the plant, while the Fava da Orto cultivar gave the highest significant values in the total pods yield. The results indicate that there are no significant differences between the biofertilization and non-biofertilization treatments in all the studied traits. The concentration of 30 mg/L boron gave the highest significant value in the number of seeds per pod. The treatment of 1 ml/L of biofertilizer with 30 mg/L of boron in the Fava da Orto cultivar gave the highest significant values in the leaf area of the plant and the total pods yield.
