White yam (Dioscorea rotundata Poir.) is an important tropical tuber crop which contributes to food and nutritional security for millions of people in many countries in Africa, South America and Asia. There exists large variability in the yield of white yam and one of the ways to bridge the gap is by managing the spatial and temporal variability in soil characteristics. The site specific nutrient management (SSNM) using QUEFTS model is very successful in increasing the yield, income and nutrient use efficiency. On station experiments were conducted to evaluate the performance of 8-year-old continuous SSNM on soil quality. Normalised SQI showed significant difference among the treatments which was significantly higher in SSNM treatment compared to present recommendation. The percentage of contribution of indicators to soil quality score showed that available iron is the major contributor followed by phosphatase activity and available phosphorus. The final normalized PCA based soil quality equation is Normalized SQI = 0.636 (Spnitrophenol/3) + 0.192 (SFe/2) + 0.173 (SP /1). Keywords Not Available |
