摘要

With the aim of reducing negative effects of climate change on crop production and to minimize the loss of soil by erosion, thereby enhancing farmers’ resilience to climate change, climate smart agricultural interventions (CSA) were initiated at Bona Dibero landscape of Soro district. Understanding the effect of CSA practices is crucial for scaling up effective practices as it could provide substantial economic benefit and create favorable conditions for better ecological stewardship. This study evaluated the effects of CSA practices on soil properties and wheat yield in cultivated lands of Bona Dibero. Data were collected from four different fields with CSA interventions were implemented for: 2 years, 5 years, 9 years and land without CSA practices (control). The result indicated that bulk density of the soil (Bd) (g cm−3), pH-H2O, OC (%), TN (%) and Av. P mg/kg were significantly influenced by CSA practices. The highest and lowest average values of the soil parameters were found in fields with 9 years of CSA practices and fields without CSA practices respectively. Analysis of agronomic data also indicted that CSA practices significantly (p ≤ 0.001) improved plant height, tiller formation, spike length, thousand seed weight, biomass, and grain yield of wheat. CSA practices for 9 years improved grain yield of wheat by 15.02% than control. Thus, it is concluded that CSA practices have assured positive effects on soil properties and wheat yield, the influence increases with duration of establishment.
