Response of soil test crop response (STCR) approach on available nitrogen, phosphorus and potassium status after Wheat (Triticum aestivum L.) harvest in an acid Alfisol

Abstract

The field experiment was carried out on wheat during rabi, 2017-18 to study the prescription based fertilizer application on soil properties in a long term experiment of Department of Soil Science CSK HPKV, Palampur. The experiment was laid out by Randomized block design (RBD) consisting of eight treatments which are replicated thrice. The application of fertilizers based on soil test crop response (STCR) along with application of FYM @ 5t ha-1 recorded significantly higher available N, P and K. Further the physical properties such as bulk density, particle density, porosity and water holding capacity were observed when compared to the other treatment combination carried out during the experiment viz., general recommended dose (GRD) of NPK, control, soil test based. Overall, we concluded that the input of STCR approach had positive effects on soil properties.
