A field study involving nine treatments comprising STCR-based integrated nutrient management modules to improve soil health, fertilizer-use efficiency and productivity of wheat crop (Triticum aestivum L.) was conducted in randomized block design during 2021-22 and 2022-23 at Rajasthan College of Agriculture, Udaipur, Rajasthan, India. STCR based integrated nutrient management study was conducted to examine its importance in attaining target yields, improving soil nutrient status and nutrient utilization in wheat (Triticum aestivum L.). The experiment was carried out for two consecutive years in the wheat crop. The nitrogen (N), phosphorus (P) and potassium (K) requirement for attaining targeted yield of wheat (50 q/ha) were estimated following soil test crop response-based target yield equations (TYE). Results indicated that the 75% STCR + vermicompost (2 t/ha) (T6) recorded highest grain (5321 kg/ha) and straw (7048 kg/ha)yield of wheat, which were 21.37 and 21.66 % higher in terms of grain and straw yield over 100 % RDF (T2), respectively. 75% STCR + vermicompost (2 t/ha) was remained statistically at par with the treatment 75% RDF + vermicompost (2 t/ha) (T4) with respect to grain and straw yield of wheat. The available N, P2O5 and K2O content in post-harvest soil were significantly improved with 100% RDF through vermicompost + Azotobacter (T8)and it was found statistically at par with the application of treatments 75% STCR + vermicompost (2 t/ha) (T6)and 75% RDF + vermicompost (2 t/ha) (T4). The two year study based on STCR under INM clearly demonstrated that STCR based integrated use of fertilizers can produce target yields and save the fertilizer without destroying soil fertility and soil health

Application of 75% Soil Test Crop Response (STCR) along with vermicompost at a rate of 2 tons per hectare (T6) not only produced the targeted yield of wheat but also improved the soil fertility as compared to application of chemical fertilizer alone. Thus, 75% Soil Test Crop Response (STCR) along with vermicompost at a rate of 2 tons per hectare can play a vital role in exploiting high yield potential of wheat crop through its beneficial effect on nutrients supply and soil properties
