ORGANIC AMENDMENTS ON LIGHT TEXTURED SOILS IN GANGES FLOOD PLAIN (AEZ-10) FOR UPLAND CROP PRODUCTION

The experiment was conducted in a charland located in Charharirampur union under Faridpur district in the physiography of Active Ganges Floodplain (AEZ-10) during 2011-2014. The Crops selected were BARI Wheat-24 (Prodip) and Porangi, a local variety of B. aus. Fertilizer treatments in wheat were: T₁= Farmer´s fertilizer practice=130%N-70%P-55%K-100%S-0%Zn-100%B+Cowdung@6t/ha; T₂=100%NPKSZnB of Recommended Doses; T₃=90%N-87%P-67%K-100%SZnB+Cow dung @ 3t/ha and T₄=88%N-55%P-77%K-100%SZnB+ poultry manure @ 1.5 t/ha. Fertilizer treatments for Broadcast Aus were: T₁=Farmer´s practice=154%N-71%P-90%K-100%S-0%Zn+Cow dung @6ton/ha; T₂=100%NPKSZn of Recommended Doses; T₃=62%N-60%P-0%K-100%SZn+ Cow dung @ 3 t/ha and T₄=50%N-00%P-19%K-100%SZn+Poultry Manure @ 1.5 t/ha. Inorganic fertilizers P, K, S, Zn, and B applied in full dose at final land preparation. Fertilizer N fertilizer applied in three splits. The yield of wheat was found maximum in case of T₃ treated plots (3.82 t/ha) followed by T₂ treated plots (3.70 t/ha), then T₄ treatment (3.67 t/ha) and the lowest yield was obtained from farmer´s own practice (T₁, 3.30 t/ha). The yield of B. Aus was found maximum in case of T₃ treated plots (2.91 t/ha) followed by T₄ treated plots (2.87 t/ha), then T₂ treatment (2.85 t/ha) and the lowest yield was obtained from farmer´s own practice (T₁, 2.53 t/ha). Organic amendment with cow-dung (IPNS) (T₃) and poultry manure (IPNS) increased wheat yield performance compared to farmer´s practice. But it did not perform better than T₂. In case of B. Aus organic amendments gave better results than T₁ and T₂. T₃ treatment has positive impact for N, P, S over T₂, and T₁ but the differences were not significant. T₄ treatment has positive impact on P and Zn over T₂ treatment but it was statistically not significantly higher. Different treatments affected on soil OM and pH and significant difference lies between T₁ and T₄. T₃ treatment is significantly higher than all other treatments. This means organic amendment with cow dung has positive and statistically significant impact on soil organic matter. T₄ also has positive impact on OM over T₂, but the difference is not statistically significant. Land use and soil survey was done in char Harirampur union. This area is under the physiography of Active Ganges Floodplain (AEZ-10) and crops grown in the site in two seasons viz. Rabi (winter) and Kharif-1 (pre-monsoon).
