 ABSTRACT

An experiment on microbial load of soil under aerobic rice based intercropping was conducted with two land configuration method and five rice based intercropping systems in Southern Transition Zone of Karnataka under drip fertigation during the Kharif 2016 and 2017 on sandy loam soils at College of Agriculture, Shimoga. Microbial population showed significant variations due to land configuration methods and intercropping systems in paired row of rice. Raised bed method of land configuration registered significantly higher microbial population of bacteria, fungi and actinomycetes at harvest (33.98 x 10-5, 31.98 x10-6, 24.33 x10-3, 23.50 x10-4, 21.15 x10-2 and 19.60 x10-3cfu g-1 of soil, respectively) and among the intercropping system aerobic rice with soybean witnessed significantly higher population of bacteria, fungi and actinomycetes (38.06x10-5, 35.95x10-6, 26.39x10-3, 25.24x10-4, 22.26x10-2 and 20.86x10-3 cfu g-1 of soil, respectively). From this experiment it can be concluded that cultivation of rice under raised bed along with intercropping with soybean and fertigation through drip can helps to enhance microbial load of the soil. 

Key words: Microbial load, Bacteria, Fungi, Actinimycities, Rice, Kharif.
