Targeted yield equations of wheat crop for acid Alfisol soil of Jharkhand

Abstract

An experiment was conducted in the experimental plot of Birsa Agricultural University Ranchi in the year on wheat crop. Soil type of the site was acid Alfisol. Three strips each of 24 sub-plots were created to develop 3 distinct fertility gradients, low medium and high during Kharif season to take test crop as wheat during Rabi season. Soil Test Crop Response (STCR) equations were developed for Targeted yield of wheat, cultivar K1006 in the acidic soil. Available nitrogen, phosphorus and potash along with uptake of NPK were estimated to before calculation of STCR fertilizer prescribed equations for targeted yield. A Ready Reckoner for different Soil Test Value for targeted yield of 50 q/ha and 60 q/ha of wheat crop, cv. K 1006 in acidic soil of Jharkhand were estimated.
