The biogas technology is the only promising renewable energy source attributed with dual benefits in the form of supply of a clean and high calorific fuel to meet the domestic fuel needs of rural areas. It also emphasis with a provision of anaerobic treated bio digested slurry with high manure value. The poultry dropping and manure component of this waste has a high nutritional value and traditionally used as application on soil in open field as an organic manure. The present study was carried out to evaluate the effect of biodigested poultry litter slurry as a nitrogen source and compost generated by a biogas reactor. Field experiments were carried out with biodigested slurry supplemented with chemical fertilizer for the bhendi crop with five different treatments and replications with biodigested slurry direct application and biodigested slurry compost application. Among the treatments, application of 12.5 t ha-1 of biodigested compost showed maximum yield of 19.55 t ha-1 followed by the application of 9.37 t ha-1 of biodigested compost yield 18.78 t ha-1. Similarly results were obtained for the direct application of biodigested poultry slurry in the field with the maximum yield of 19.86 t ha-1 followed by 19.60 t ha-1 with the application rate of 75 % slurry + 25 % RDF nitrogen and of 25 % slurry + 75 % RDF nitrogen respectively. The study was concluded with the findings that supplementing the liquid slurry with fertilizer can save up to 75 % of N fertilizer cost and 12.5 t ha-1 of biogas compost will improve the productivity of bhendi. The biodigested slurry from poultry droppings was found to be better alternative way of organic farming instead of direct application in rural areas. This may pave a way to utilize the local available resources to increase the income of the organic farming farmers.
