Visualizing nutrient synergies: STCR approach towards NPK balancing and yield targeting in barnyard millet

Key Points

This research aims to evaluate the STCR approach for balancing NPK nutrients and targeting yields in barnyard millet.
Utilized the STCR (Soil Test Crop Response) approach
Incorporated FYM (Farmyard Manure) into the nutrient management system
Assessed soil fertility and nutrient-use efficiency
Evaluated targeted yield achievement in different agroecological settings
Increased nutrient-use efficiency compared to traditional methods
Achieved targeted yields within ± 10%
Enhanced soil fertility and system resilience across various conditions

Abstract

The STCR approach with FYM integration enhances soil fertility, nutrient-use efficiency (higher RE and PFP for NPK vs. GRD/soil rating), and system resilience while achieving targeted yields within ± 10%. This provides a viable pathway for sustainable millet intensification across agroecological conditions.
