The acid sulphate soils are found at some places in Sundarbans region of West Bengal. These soils are highly acidic, deficient in P and, high in Fe and Al content with very poor crop yield. In the present investigation the effect of P -fertilizer, lime and green manure on the productivity of rice and effect of P -fertilizer and residual effect of lime on sunflower was studied under farmer's field condition with an objective to develop strategies for the efficient management of these soils. Under the on -farm study 3 doses of P [0, 40 (recommended dose) & 80 (double of recommended dose) P205 kg ha -1], 3 doses of lime (0, half & full of lime requirement determined by KCI extraction method) with or without green manure were evaluated under RBD laid out field experiment with 3 replications. Locally available oyster shells (milled) were applied as cheap source of lime during dry season. Significant increase in the plant growth parameters like plant height and root density was recorded at double the recommended dose of P followed by the recommended dose compared to no P -fertilizer treatment. The increase in grain and st.aw yield of rice and grain yield of sunflower was also followed the same trend. The improvement in growth and yield of rice due to application of limo and residual effect of lime on yield of sunflower at P -fertilizers treatments with full lime requirement dose was at par with half lime requirement dose. The effect of the application of green manure was found to be significant at all the treatments of P fertilizer and lime. Limo application resulted in increase in pH of soil and decease in KCL extractable Al and, DTPA extractable Fe and Mn of the soil. The available P content of the soil has been increased due to application of P -fertilizer as well as lime. Not Available |
