Effect of Adding Urea and Organic Fertilizers on the Growth and Productivity of Faba bean (Vicia faba L.)

The experiment was conducted in pots to study the effect of adding organic fertilizer and levels of urea fertilizer and the interaction between them on the growth and yield of bean plant (Vicia faba) (plant height, number of bacterial nodes, dry weight of bacterial nodes, dry weight of vegetative total and total yield).

Organic fertilizer (decomposing poultry waste) was added at five levels, namely (0,1,2,3,4) tons/ha^-1 and five levels of urea fertilizer, which are (0, 25, 50, 75 or 100) kg/dunum to the soil before planting .

Result showed the superiority of urea fertilization treatment plants 75 kg/dunum in increasing plant height, dry weight, number of bacterial nodes, dry weight and total yield of seeds with a decrease in the degree of soil interaction compared to the comparison treatment plants that gave the lowest values of the above traits with the highest values of the degree of soil interaction. The addition of organic fertilizer (3 tons/ha) also led to the superiority of all the qualities under study plants in plant height, dry weight, number of bacterial nodes, dry weight and total yield of seeds, while reducing the degree of soil interaction compared to plants not treated with organic fertilizer. Interference treatment plants of 75 kg/dunum urea and 3 tons/ha^-1 organic fertilizer showed the highest values for the traits under study with the lowest value of the degree of soil interaction.
