Sugarcane is one of the most important cash crops of the India. Study was carried the effect of Glucanoacetobacter diazotrophicus and PSB formulations on quality parameter on suru sugarcane. Out of seven treatment the T3 . 50% N+ Glucanoacetobacter lignite based set treatment was found most effective than other treatment as it recorded the highest NMC, Sucrose Glucanoacetobacter population at harvest stage of the crop, however, it was at par with T2 . RDF (100% N, P2O5 and K2O), T4 . 50% N+ Glucanoacetobacter liquid based set treatment, T5 . 50% N+ Glucanoacetobacter lignite based seedling treatment, T6 . 50% N+ Glucanoacetobacter liquid based seedling treatment and T7 . 50% N+ Glucanoacetobacter liquid based foliar spray treatment in most of growth, yield, microbial and quality parameter. They save 50% N (125 kg/ha) and 25% P (29 kg/ha) for suru sugarcane besides the improved yield, quality and sustenance of soil fertility. | Study the effect of Glucanoacetobacter Diazotrophicus and PSB formulations on quality parameter on suru sugarcane
