摘要

新的农业技术,如抗逆性水稻品种(strv),可以降低产量风险,从而改变农民的生产决策。本文探讨了在非干旱年份采用STRV如何影响尼泊尔农民的决策和生产力。strv的培育是为了高产和耐气候冲击,如干旱。为了评估投入测量对治疗效果的影响,我们收集了900户家庭关于STRV采用和投入使用的信息。我们还进行了一项调查实验,其中一半的抽样家庭被随机分配回答有关农业投入的额外、更详细的问题。与传统品种(TVs)相比,农民在种植strv的地块上施用更多的总化肥、农药、早季化肥和整地劳动。详细的投入数据增强了我们对STRV采用与其他高产品种相比对投入使用的“挤进”效应的理解。虽然农民在其他改良品种(如杂交品种)上增加了这些投入物的一部分的应用,但结果表明,拥挤效应对strv最为一致。在没有干旱的情况下,与其他非抗旱性改良品种相比,strv也提供了类似的增产和减少产量方差的效果。结果表明,改良品种的采用,特别是STRV的采用,可以提高家庭生产力和农业现代化。

Measuring the impact of stress-tolerant rice variety adoption: Evidence on input use and yield in Nepal

New agricultural technologies, such as stress-tolerant rice varieties (STRVs), that reduce yield risk can modify farmers’ production decisions. This article explores how STRV adoption affects farmer decision-making and productivity in Nepal in a non-drought year. STRVs are bred to be high-yielding and tolerant to climate shocks such as drought. To assess the effect of input measurements on treatment effects, we collected information from 900 households on STRV adoption and input use. We also conducted a survey experiment in which half of sampled households were randomly assigned to answer additional, more detailed questions on agricultural inputs. Farmers apply more total chemical fertilizer, pesticides, early-season chemical fertilizer, and land preparation labor to plots planted with STRVs compared to traditional varieties (TVs). Detailed input data enhances our understanding of how this “crowding-in” effect of STRV adoption on input use compares with other high-yielding varieties. While farmers increase application of a subset of these inputs on other improved variety types such as hybrids, results suggest that crowd-in effects are most consistent for STRVs. In the absence of drought, STRVs also provide a similar yield boost and yield variance reduction over TVs compared to other, non-stress tolerant improved varieties. Results suggest that improved varietal adoption, and STRV adoption in particular, can improve household productivity and modernization of agriculture.

期刊介绍: Agricultural Economics aims to disseminate the most important research results and policy analyses in our discipline, from all regions of the world. Topical coverage ranges from consumption and nutrition to land use and the environment, at every scale of analysis from households to markets and the macro-economy. Applicable methodologies include econometric estimation and statistical hypothesis testing, optimization and simulation models, descriptive reviews and policy analyses. We particularly encourage submission of empirical work that can be replicated and tested by others.
