Impact of Different Approaches of Nutrient Recommendations for Aerobic on Soil Fertility of Alfisols of Eastern Dry Zone of Karnataka

A field experiment to study the impact of different approaches of nutrient recommendations for aerobic on soil fertility of Alfisols of Eastern Dry Zone of Karnataka was conducted during Kharif 2020 at Zonal Agricultural Research Station (ZARS), GKVK, Bengaluru. The experiment was laid out in RCBD comprising twelve treatments replicated thrice. The results revealed that significantly higher grain yield (68.85 q ha-1) was recorded in treatment receiving fertilizer nutrients based on Soil Test Crop Response (STCR) inorganic approach for the targeted yield of 65 q ha-1 based on predicted soil test values which was superior compared to Low-Medium-High (LMH) approach and Blanket recommendation The higher post- harvest soil available nutrient status was registered in STCR integrated approach based on predicted soil test values compared to package of practice and LMH approach.
