Soil‐test crop response correlation studies on postrainy season sorghum (Sept/Oct‐Dec/Jan) based on yield goal approach were conducted in a vertisol. The results indicated that 2.07 kg N, 0.34 kg P and 2.00 kg K were required to produce one quintal of grain sorghum (cv. CSH 8 R). The contribution of N, P and K from soil and fertilizers was 34, 31.87, 16.66 and 44, 17.03, 60 percent, respectively. The results of the 19 yield goal trials showed that about 75% of the yield goal of 60 q/ha were achieved within ± 10% variation. From the test of significance, the differences between the yield goal of 60 q/ha and the actual yield of sorghum obtained were nonsignificant indicating that yield goal of 60 q/ha was achieved. The results indicated higher utility of yield goal approach in making sound fertilizer recommendations for sorghum in vertisols.
