tailieunhanh - Effects of preceding scented rice varieties in combination with organic inputs on soil microbial properties in scented rice (Oryza sativa)-Lathyrus (Lathyrus sativus L.) relay cropping under organic system

A field experiment was conducted during Kharif and Rabi seasons 2016-17 to evaluate the effects of preceding scented rice varieties and carry-over nutrients on soil microbial properties (microbial biomass carbon, microbial population and dehydrogenase activity) in scented rice-lathyrus relay cropping under organic system. The nine treatments included three scented rice varieties and five organic inputs and one control which were laid out in factorial RBD with 3 replications. Among the three preceding scented rice varieties, the highest microbial biomass carbon ( TPF/g/day) and dehydrogenase activity ( TPF/g/day) was found in CR-Dhan-909 and the highest microbial population was found in kola joha [soil bacteria ( cfu/g) and fungi ( cfu/g)]. In case of carry-over nutrients, enriched compost recorded highest microbial biomass carbon ( TPF/g/day), dehydrogenase activity ( TPF/g/day), soil bacteria ( cfu/g) and fungi ( cfu/g). | Effects of preceding scented rice varieties in combination with organic inputs on soil microbial properties in scented rice (Oryza sativa)-Lathyrus (Lathyrus sativus L.) relay cropping under organic system
