Abstract:

Field experiment was undertaken to evaluate the response of sugarcane variety CoC 24 to application of bioinoculants, viz., Gluconoacetobacter diazotrophicus, AM fungi and Azophos (Azospirillum and phosphobacteria), under different levels of N, P2O5 and K2O inorganic fertilizer. The results revealed that the application of mycorrhizae, G. diazotrophicus, Azospirillum and phosphobacteria significantly produced higher cane yield in plant crop. The application of Gluconoacetobacter diazotrophicus @10 kg + AM fungi @ 50 kg/ ha + Azophos @10 kg + 75 % NPK recorded higher germination (87.36 %) and maximum tiller population (1,94,185/ha). The soil samples were collected before planting and after application of inorganic fertilizers and bioinoculants and were analyzed for the microbial population count and also for the dynamics in the soil nutritional status. The bacterial, fungal and diazotrophs population was also maximum with the application of G. diazotrophicus+ AM fungi + Azophos + 75 % NPK. It also significantly enhanced the total nitrogen content, available phosphorous, potassium and organic carbon content in the soil. We have also recorded the maximum mean millable cane population of 1.32 lakhs /ha, cane yield (137.45 t/ha) and sugar yield (16.96 t/ha). Applied bacterial sources helped in nitrogen fixation. Continuous mobilization and solubilisation of nutrients and their persistence and colonization in soil was an added advantage which also enhanced the soil fertility.
