Effects of different dose of nitrogen and lime on soil properties and maize (Zea mays L.) on acidic nitisols of Northwestern Ethiopia

This study was carried out on the nitisols of Burie district, Ethiopia to examine effect integrated use lime and nitrogen soil physicochemical properties maize yield. Two levels (0 0.5 t/ha) five-level (0, 46, 92, 138 184 kg N/ ha) were laidout in randomized complete block design with three replications. The results indicated that among before planting, bulk density (BD), pH, organic carbon (OC), total (TN), available P CEC 1.42 g/cm3, 5.2 (strongly acidic), 1.32% (very low), 0.12% (low), 8.86 mg /kg 19.57 cmolc (medium), respectively. except increased. lowest BD (1.21 g/m3) from plots treated t/ha ha. maximum pH (6.85) obtained ha lime. (35.38 (cmolc /kg) Level lime, fertilizer, interaction effects fertilizer (L×N) significantly affected yield (p<0.001). Indeed has positive correlations most but negative (r= -0.543). adjusted net benefits 6.4 1101.77$. Inherent are changed either by sole or combined N fertilizer. Soils tilled kg/ha found benefit. Residual long-term should be researched. Thus, liming given an emphasis acidic amelioration. Moreover, government may facilitate supply farmers.
