Abstract

The study was undertaken to determine the effect of Resource conserving technologies (RCTs) viz., zero tillage (ZT) and bed planting (BP) over conventional tillage (CT) on different soil quality indicators under the rice-wheat cropping system. Out of 16 soil properties measured, 13 were statistically different (P<0.05) under different RCTs. Nutrient availability and microbial indicators were found to be significantly improved under zero tillage and bed planting than the conventional tillage. PLFAs, the environmental stress biomarkers were present in lower amounts under ZT and BP than in CT. Evaluation of soil quality indices (SQI) using minimum data set selection and principal component analysis revealed a higher value of SQI for ZT and BP than CT.
