An experiment on soil test crop response (STCR) correlation studies was conducted in Inceptisols of Varanasi, Uttar Pradesh during rabi 2010-11. Using the basic data, fertilizer adjustment equations have been developed for prescribing optimum fertilizer doses to attain different yield targets. The requirement of N, P2O5 and K2O for wheat was found to be 23.2, 7.2 and 19.2 kg t-1, respectively. The per cent nutrient contributions from soil were 19.1, 31.7 and 19.8; from fertilizers 54.9, 68.5 and 73.1, and from organic manure 6.83, 4.12 and 12.1 for N, P2O5 and K2O, respectively. The fertilizer adjustment equations at varying soil test values for attaining yield target of 3.5 and 4.5 t ha-1 of wheat have been calibrated based on the targeted yield concept. Â The targeted yield equations and the fertilizer ready reckoners developed for wheat will be useful for large scale recommendation by the soil testing laboratory of eastern Uttar Pradesh.Downloads
