Abstract

Evaluating the impact of agricultural practices helps policymakers and farmers in their decisionmaking. In Zambia, most households depend on agricultural activities, in particular maize production. This paper examines the impact of the adoption of residue retention on households’ maize yield in northern Zambia. We used the propensity score matching (PSM) method. By using the probit model, we also determined the factors that influence the adoption of residue retention. The results show that adopting residue retention has a positive and significant net effect on household maize yield. Residue retention traps moisture in the soil and improves soil structure. This suggests that a greater focus on this aspect is required to encourage more farmers to adopt residue retention to improve maize yield. Government policies can be structured to promote residue retention among smallholder farmers.

评估农业实践的影响有助于决策者和农民做出决策。在赞比亚，大多数家庭依靠农业活动，特别是玉米生产。本文考察了赞比亚北部采用残茬保留对农户玉米产量的影响。我们使用倾向得分匹配(PSM)方法。通过probit模型，我们还确定了影响残馀保留采用的因素。结果表明，秸秆保留对农户玉米产量有显著的正净效应。残留在土壤中的水分和改善土壤结构。这表明需要更多地关注这方面，以鼓励更多的农民采用残茬保留来提高玉米产量。政府可以制定政策，以促进小农的剩余物保留。
