Integrated Effects of Vermi-Compost and NPS Fertilizer Rates on Soil Chemical Properties and Bread Wheat Production in Gechi District, Western OROMIA

Information on soil fertility status and crop response to different soil fertility management is very important to come up with sustainable crop production plan. A study was conducted in Gechi District on farmers' fields to find out the combined effects of vermi-compost (organic fertilizer) and NPS (inorganic fertilizer) rates on soil chemical properties and bread wheat production. The treatments consisted of three levels of vermi-compost (0, 1.5 and 3 t ha-1) and three levels of NPS fertilizer (0, 100 and 200 kg ha-1). The experiment was laid out in RCBD design in factorial combination with three replications., laboratory analysis results of composite soil samples collected before sowing showed deficiency in soil chemical properties. However, analysis of variance of post-harvest composite soil samples collected from each plot indicated significant differences in soil pH, available P, OC, TN and CEC while, soil exchangeable acidity showed positive improvement as compared to the initial one. The analysis of variance among the treatments showed significant differences (P ≤ 0.05) on almost all the bread wheat characters tested. The highest and lowest bread wheat grain yield (5722.2 kg ha-1) and (750.0 kg ha-1 were obtained from the treatment combination of 3 t ha-1 vermi-compost with 200 kg ha-1 NPS and 92 kg ha-1 N, and control plot, respectively. Therefore, the present study revealed that combined fertilization of vermi-compost and NPS fertilizer enhanced bread wheat productivity and soil fertility status in the study area but indicated that bread wheat productivity in the study sites was reduced due to high demand for external nutrient inputs. Hence combined fertilization of 3 t ha-1 vermi-compost with 200 kg ha-1 NPS and 92 kg ha-1 N could improve crop productivity and soil chemical properties, and is recommended for the study area (Gechi District) and similar agro-ecology. The result also showed that the soils of the study sites had poor chemical fertility and integrated soil fertility management practices can improve the current situation.
