IMPACT OF CONSERVATION AGRICULTURE AND WEED CONTROL MEASURES ON SOIL PHYSICAL AND BIOLOGICAL PROPERTIES UNDER RICE-WHEAT-MUNGBEAN CROPPING SYSTEM IN VERTISOLS
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 53
Abstract
A field experiment was conducted during 2014-15 and 2015-16 at DWR, Jabalpur (M.P.) to assess the impacts of conservation agriculture and weed control measures on soil physical and biological properties under rice-wheat-mungbean cropping system in vertisols. The experiment consisted of fifteen treatments comprising of, five tillage as main-plot treatments and three weed control measures as sub plot treatments were, laid out in split plot design with three replications. Among the tillage treatments, maximum bulk density was found in transplanted rice-conventional tilled wheat (1.41 g/cc) followed by zero tillage in rice -wheat -mungbean without presence of previous crop residues (1.40 g/cc) after the second year of experiment. Maximum porosity (47.81 %) was observed in conventional tillage in both rice and wheat with zero tillage in mungbean with presence of previous crop residues. However, weed control measures did not affect the bulk density and porosity of soil. Zero tillage in rice-wheat-mungbean with previous crop residues had higher population of total bacterial (14.43 and 29.12 x 106 cfu/g first and second year respectively), and, fungal, (10.20 and 18.89 x 104 cfu/g, first and second year respectively) actinomycetes (9.23 and 14.08 x103 cfu/g first and second year respectively) and dehydrogenase (20.74 and 26.03 µg TPF/ soil/2hr, first and second year respectively) activity during both years. Whereas, maximum population of bacteria, fungus, actinomycetes and dehydrogenase activity (15.90 and 28.63 x 106 cfu/g, 9.46 and 21.55 x 104 cfu/g, 11.10 and 14.48 x103 cfu/g and 25.05 and 35.99 µg TPF/ soil/2hr, first and second year respectively) was found in weedy plots.
