Abstract :The present study examined the effectiveness of biogas slurry insert ignore into journalissuearticles values(liquor from anaerobic digestion process); as a nitrogen source for the production of maize fodder insert ignore into journalissuearticles values(Zea mays);. Maize fodder was cultivated as a control insert ignore into journalissuearticles values(T0: 0 kg of slurry N ha-1); and with 3 different levels of biogas slurry-T1 insert ignore into journalissuearticles values(60 kg of slurry N ha-1);, T2 insert ignore into journalissuearticles values(70 kg of slurry N ha-1);, and T3 insert ignore into journalissuearticles values(82 kg of slurry N ha-1);-in a randomized block design. The parameters studied were plant height, stem circumference, number of leaves, leaf area, dry matter yield, and nutrient contents in maize fodder. Maize plant height and stem circumference were significantly insert ignore into journalissuearticles values(P < 0.01); influenced by increasing the rate of biogas slurry 14, 28, 42, and 56 days after sowing. The number of leaves in fodder plants did not differ significantly, but leaf area significantly insert ignore into journalissuearticles values(P < 0.01); differed between the treatment groups. The highest maize fodder biomass yield was observed in T2 insert ignore into journalissuearticles values(54.12 t ha-1);. In the case of crude protein, a significant difference insert ignore into journalissuearticles values(P < 0.01); was observed between the treatment groups and the highest value was also observed in T2 insert ignore into journalissuearticles values(11.91%);. A significant difference was also observed in dry matter insert ignore into journalissuearticles values(P < 0.05); and ash insert ignore into journalissuearticles values(P < 0.01); content between the treatment groups, but not in acid detergent fiber insert ignore into journalissuearticles values(ADF); or neutral detergent fiber insert ignore into journalissuearticles values(NDF);. Based on these results, it may be concluded that the application of approximately 70 kg of biogas slurry N ha-1 will improve the production of biomass and nutrient content in maize fodder.
