- Intervention effect Soil quality parameters were significantly influenced by management treatments in both experiments.
- Intervention effect Low tillage plus interculture and weedicide gave a greater soil quality index of 0.98.
- Intervention effect Conventional tillage plus interculture had an SQI of 0.94, at par with low tillage plus interculture at 0.93.
- Intervention effect The 100% organic nutrient source treatment gave the greatest SQI of 1.05.
- Intervention effect A half organic and half inorganic nitrogen treatment had SQI 0.92, statistically at par with fully inorganic nitrogen at 0.88.
- Association In experiment 1 organic carbon contributed 17% to SQI.
- Association In experiment 1 exchangeable calcium contributed 10% to SQI.
- Association In experiment 1 available zinc contributed 9% to SQI.
- Association In experiment 1 available copper contributed 6% to SQI.
- Association In experiment 1 dehydrogenase assay contributed 6% to SQI.
- Association In experiment 1 microbial biomass carbon contributed 25% to SQI.
- Association In experiment 1 mean weight diameter of soil aggregates contributed 27% to SQI.
- Observation Experiment 2 SQI ranged from 2.33 to 3.47.
- Intervention effect Half urea and half farmyard manure gave greatest SQI 3.47.
- Intervention effect The half urea and half manure treatment was at par with RDF plus zinc sulfate SQI 3.20.
- Association In experiment 2 organic carbon, available nitrogen, and exchangeable calcium contributed 19%, 20%, and 3% to SQI, respectively.
- Association In experiment 2 zinc and copper contributed 4% and 17% to SQI.
- Association In experiment 2 labile carbon and aggregate mean weight diameter each contributed 20% and 17% to SQI.
- Association The relation of mean pearl millet yield to relative soil quality index may permit quantitative yield prediction from soil quality change.
