The nutrient value and protein content of vegetable soybean makes excellent source for enriching human diet. However the productivity and production of vegetable soybean is low due to lack of nutrient management specific to vegetable soybean leading to considerable variability in yield and quality. In this regard an experiment was conducted to study the response of vegetable soybean to fertilizer levels in northern Karnataka. Fertilizer levels significantly the nutrient uptake with 125 per cent Recommended Dose of Fertilizer (RDF) recording significantly higher nutrient uptake particularly vegetable soybean Swarna vasundhara. However JS 335 showed significantly higher K uptake resulting in pod number and Harvest Index (HI). Sustainable nutrient management must be efficient and effective. Increased level of fertilizer resulted in increased nutrient uptake by Swarna vasundhara, but internal nutrient utilization (IE) was low compared to JS 335 indicating the nutrient imbalance or other stresses. Among the treatments JS 335 with 125 per cent RDF recorded maximum post-harvest soil nutrient status with positive net gain indicating the balanced nutrient for soil health sustainability. On the other hand Swarna vasundhara with all the fertilizer levels showed low post harvest soil nutrient status with negative net gain for all nutrients indicating the need for evolving the separate fertilizer dose for vegetable soybean for the northern dry zone of Karnataka.
