Abstract
Soybean is the principle oil seed crop in India. Blanket recommendation of fertilizers for soybean over large area irrespective of soil type has lead to indiscriminate use of costly inputs. This has also resulted in imbalanced use of fertilizers and environment related problems. Hence to economize the fertilizer use soil testing should play important role. Therefore, a study on the soil test for improving soybean productivity was performed as a part of mandatory program of Agriculture Science Center, Rewa in Madhya Pradesh (MP) of India. Soils of study area had pH 6.8 to 7.4, EC 0.17 to 0.23 dSm−1, organic carbon 0.33 to 0.71%, available nitrogen 105 to 214 kg/ha, phosphorus 7.30 to 16.80 kg/ha and potassium 173 to 325 kg/ha. Experiment were conducted in rainy season of 2009–10 with two treatments, farmers practice -T1 (50 kg DAP/ha only) and application of fertilizer on the basis of soil test value -T2. Higher grain yield was observed in T2 (1830 kg/ha) than T1 (1180 kg/ha). The maximum increase in soybean yield was noted due to applied fertilizers on the basis of soil test values in T2. The highest Benefit Cost ratio (B:C ratio) 4.05 was registered in T2.
