概括

干直接种子大米 (dDSR) 的采用通过降低成本增加了印度农民的收入,尽管产量影响不同. 政策应该鼓励更广泛地采用dDSR,以获得经济效益.

科学领域:

农业经济学农业经济学
农业学是一种农业学.
可持续农业可持续农业

背景情况:

池移植大米 (PTR) 面临着劳动力,用水和成本方面的挑战.
干直接种子大米 (dDSR) 提供了一个潜在的替代品,但其在不同农业气候区的经济可行性对于采用至关重要.
了解dDSR的经济影响是其在印度大米种植中广泛实施的关键.

研究的目的:

评估采用干直接种子大米 (dDSR) 对印度四个主要大米种植州的种植成本,大米产量和净收入的经济影响.
通过使用地块和家庭数据,比较dDSR与传统水池移植大米 (PTR) 的性能.
为决策者提供基于证据的建议,以促进dDSR的采用.

主要方法:

倾向性得分匹配 (PSM) 用于分析经营种植成本,米产量和净收入.
使用内源切换回归 (ESR) 来估计采用dDSR的产量效应,控制观察到的和未观察到的异质性.
分析使用来自印度四个米种植州的地块和家庭数据进行.

主要成果:

dDSR的采用显示了Uttar Pradesh,Andhra Pradesh和Telangana的米产量增长的潜力,而Madhya Pradesh则出现了下降.
在所有四个研究的州,来自种植的净收入显著增加,从5009卢比/英到8134卢比/英.
发现采用dDSR可以降低资源贫困农民的米生产成本.

结论:

干直接种子大米 (dDSR) 是提高印度大米种植农民收入的可行策略.
尽管产量存在区域差异,但采用dDSR的整体经济效益是巨大的.
建议政府的政策和战略鼓励非采用农民采用dDSR.
