Enhancing the productivity of bush snap beans (Phaseolus vulgaris L.) using organic fertilizer amendments.

Result showed that the sole application of 10 tons ha-1 of processed chicken manure provided an immediate and significant yield enhancement in bush snap beans. Its combination with biochar and wood vinegar may provide an additional improvement in yield but may require a longer period of application. The addition of wood vinegar has a significant effect in controlling bean rust disease. The use of “Bokod” variety of bush snap bean produced a highly significant pod yield. For long-term and sustainable organic snap bean production, a combined application of 10 tons ha-1 of processed chicken manure, 10 tons ha-1 of biochar, and 5 ml L-1 water of wood vinegar is used to optimize yield.
