Abstract:

A field experiment was carried out at Assam Agricultural University, Jorhat, Assam during kharif season of 2017 with a view to evaluate the biological properties of soil after cultivation of indigenous quality rice varieties under different methods of establishment. The rice varieties were kunkuni joha, amona bao, black rice and jhengoni bora and the methods of establishments were direct seeding, transplanting and System of Rice Intensification( SRI). Highest microbial biomass carbon (MBC) was recorded in SRI method (873.04μg g-1 dry soil) and lowest in transplanted rice (863.97μg g-1 dry soil). Among the varieties highest microbial biomass carbon was found in jhengoni bora (871.11 μg g-1 dry soil) and lowest in kunkuni joha and black rice (866.44μg g-1 dry soil). Dehydrogenase activity was found to be highest in SRI method (59.25 μg TPF g-1 day-1) and lowest in transplanting method (58.75μg TPF g-1 day-1). Among the varieties dehydrogenase activity was found highest in amona bao (60.44 μg TPF g-1 day-1) and lowest in kunkuni joha (56.11μg TPF g-1 day-1). Phosphomonoesterase activity followed the same trend with the highest value to be recorded in SRI method (57.09µg PNP g-1 hr-1) and lowest in transplanting method (55.12 µg PNP g-1 hr-1). Among the varieties phosphomonoesterase activity was found to be highest in amona bao (57.77μg PNPg-1hr-1) and lowest in kunkuni joha (55.58μg PNP g-1hr-1).
