The Effect of Biogas Slurry Application on Biomass Production and Forage Quality of Lolium Multiflorum

The development of ecological circular agriculture has been highly encouraged to recycle agricultural wastes, reduce mineral fertilizer input, and protect the environment. Biogas slurry (BS), a by-product biogas production generated from anaerobic digestion animal waste crop residues, is often considered substitute input. Being cheap source organic matter plant nutrients, its application may improve soil fertility yield quality quantity. field experiments were conducted in 2016 2017 study growth responses forage by applying replace chemical synthetic (CSF). Results revealed that combination with significantly (p < 0.05) improved Italian ryegrass on treatment T2, dry was increased more than 9.00%, while stem-to-leaf ratio decreased 12% (second cutting), comparison only group. In case quality, crude protein (CP) fiber (CF) content had significant difference observed between T0 T2 Compare group, CP 10.35%, CF about 10.00%. Based these results, it concluded 37.5 kg/ha CSF + 100.5 t/ha BS could biomass ryegrass.
