Abstract

Black gram and green gram are important pulse crops in India, but their production has faced fluctuations and stagnancy in yields over the last few decades. The Government of India has implemented several measures to enhance crop yield, including recommending and promoting the adoption of crop‐specific agronomic practices. However, there is limited empirical evidence on the determinants of the adoption of these practices and their impact on yield and income. In this context, this study analyses the determinants of the adoption of climate and plant management practices among black gram and green gram farmers and their impact on yield, crop revenue and net income across four major crop‐producing Indian states using a multinomial endogenous treatment effects model. Our analysis shows that information, contact with government extension services and access to off‐farm activities are crucial in adopting climate and plant management practices. The results strengthen the view that the adoption of knowledge‐intensive practices happens via formal information sources and plot‐level demonstrations. In addition, the results indicate that farmers who experience frequent crop loss exhibit an aversion towards adopting climate and plant management practices. While adopting these practices had a positive impact on crop yield and crop revenue, the impact on net income was observed only in the case of climate management.
农艺措施的采用及其对作物产量和收入的影响:对印度黑糯米和绿糯米的分析
黑糯米和青糯米是印度重要的豆类作物,但在过去几十年里,它们的产量一直处于波动和停滞状态。印度政府已采取多项措施提高作物产量,包括推荐和推广采用针对特定作物的农艺措施。然而,关于采用这些做法的决定因素及其对产量和收入的影响的经验证据却很有限。在此背景下,本研究采用多项式内生处理效应模型,分析了印度四个主要作物生产邦的黑禾和绿禾农民采用气候和植物管理方法的决定因素及其对产量、作物收入和净收入的影响。我们的分析表明,信息、与政府推广服务机构的联系以及参与非农活动的机会对采用气候和植物管理方法至关重要。研究结果进一步证实,知识密集型实践的采用是通过正规信息来源和地块示范实现的。此外,结果表明,经常遭受作物损失的农民对采用气候和植物管理方法表现出反感。虽然采用这些做法对作物产量和作物收入有积极影响,但只有在气候管理情况下才会对净收入产生影响。
