ABSTRACT:

The present study aimed to evaluate the efficiency of using the effluent from anaerobic co-digesters on water spinach yield. All experiments were set up onsite at the farmer household with 13 treatments (triplicate for each) including 10 treatments applied effluents from digesters composing of pig dung, rice straw, water hyacinth, or co-digestion; 2 treatments applied inorganic fertilizer and 1 control treatment. The results showed that treatments fertilized by effluent front digesters got the yield of 21.9-25.71 ton/ha that was not significantly different from that of with inorganic fertilizer of 23.93 ton/ha. Applying organic fertilizer source from biogas digester for planting is an optimum way of saving money to buy inorganic fertilizer, reducing the environmental pollution and direct to a green agriculture development.

Keywords:Biogas technology, co-digestion, digester's effluent, inorganic fertilizer, organic fertilizer, water spinach
