摘要

目的了解杂交水稻技术采用率低的原因。本文还评估了采用杂交品种和现代品种对作物产量的影响,对比-à-vis传统品种和传统品种。设计/方法/方法利用大规模农户调查(19877户)的单位数据,运用多元回归法了解杂交水稻种植的影响因素,运用工具变量回归法估计其影响。研究结果表明,在印度,杂交水稻通常种植在相对贫瘠的土壤上,导致灌溉成本和化肥等其他投入成本更高。此外,农民难以获得关于杂交水稻特性和相关农艺实践的信息,以及难以获得财政资源,这些都阻碍了扩大采用杂交水稻的努力。更重要的是,研究结果表明,杂交水稻相对于开放授粉的现代品种的产量优势还不够大,不足以激励人们迅速采用杂交水稻技术。考虑到杂交品种比自交系品种成本更高,增加水稻种植者获得财政资源的机会可以加速杂交水稻在印度的采用。独创性/价值该研究基于一项大规模的、具有全国代表性的农户调查的单位数据,该调查包括分布在印度各邦的19877名水稻种植者样本。

Adoption and impact of hybrid rice in India: evidence from a large-scale field survey
Purpose This paper aims at understanding the causes of low adoption of hybrid rice technology. The paper also assesses the impact of adoption of hybrids and modern varieties on crop yield, vis-à-vis the old or traditional varieties. Design/methodology/approach Using unit-level data from a large-scale survey of farm households (19,877 paddy cultivators), the authors applied multi-nomial regression method to understand the factors for adoption of hybrid rice and instrumental variable method of regression to estimate its impact. Findings The findings demonstrate that in India, hybrid rice is often grown on relatively poor soils, resulting in greater irrigation costs and for other inputs, such as fertilizers. Further, farmers' poor access to information on the traits of hybrid rice and the associated agronomic practices, as well as poor access to financial resources, hampers efforts to scale up its adoption. More importantly, the findings reveal that the relative yield advantage of hybrids over open-pollinated modern varieties is not large enough to incentivize the rapid adoption of hybrid rice technology. Research limitations/implications Given the higher cost of hybrids than the inbred varieties, enhancing paddy cultivators' access to financial resources can accelerate the adoption of hybrid rice in India. Originality/value The study is based on unit level data from a large-scale, nationally representative survey of farm households, comprising a sample of 19,877 paddy cultivators, spread across states in India.
