Effect of adding organic fertilizers and foliar application of humic acid and seaweed extract in growth and green pod yield of broad bean ( Vicia faba L. ).

Abstract

A simple experiment was conducted to study the effect of thirteenth treatments of organic fertilizer included the addition of chicken and cattle manure , granular humus and some combinations sprayed with humic acid and seaweed extract in to growth and green pods yield of broad bean. . The experiment was conducted in the farm of Agric. college, Babylon at 2012-2013 growth season as simple experiment according to Randomized complete block design (RCBD) with three replications. The results were summarized as follow: Chicken and cattle manure were superior in increasing plant height , branches number, leaf area, pods .plant-1 and pod weight compared to control, and its combinations with humic acid or seaweed extract enhanced the positive impact of increases in these parameters. Adding granular humus , humic acid or seaweed extract alone had a significant effect in increasing leaf area, pods no.plant-1 and pod weight. Chicken manure whether alone or strengthened by foliar spraying of humic acid or seaweed extract were superior significantly on chemical recommendation fertilizer treatment, and it gave an increase percentage in green pods yield (when added alone) 107% and 61.3% compared with control and chemical fertilizer recommendation, respectively.
