平衡肥料使用的产量收益
Shi Jie Yin Hang· 2025-05-29 23:15
Investment Rating - The report does not explicitly provide an investment rating for the agricultural sector in Eastern India, but it suggests potential productivity gains through optimized fertilizer use, indicating a positive outlook for agricultural investments [5][15]. Core Insights - The report highlights that rebalancing fertilizer use, specifically increasing the potassium-to-nitrogen (K-to-N) ratio, can lead to significant yield improvements, estimating a 4.8% increase in yields if the K-to-N ratio is doubled while keeping expenditure constant [5][14][54]. - The study emphasizes the importance of balanced fertilizer application for enhancing agricultural productivity, particularly in rice cultivation in Eastern India, where current practices show a significant imbalance favoring nitrogen [11][30]. - The findings suggest that knowledge constraints among farmers regarding the benefits of potassium fertilizers are a major barrier to achieving optimal fertilizer use, indicating a need for educational interventions [63][64]. Summary by Sections Introduction - The introduction discusses the role of inorganic fertilizers in improving agricultural productivity and the negative consequences of over-reliance on nitrogen fertilizers, including environmental degradation and reduced future productivity [10][27]. Data - The analysis utilizes detailed farmer-level surveys from rice fields in Andhra Pradesh, Bihar, and Odisha, focusing on the application rates of different fertilizers and their impact on yields [19][22]. Empirical Strategy - The report employs a two-stage least squares (2SLS) approach to estimate the causal impact of K-to-N ratios on agricultural output, using geographical variations in fertilizer supply chains as instruments [37][50]. Results - The results indicate that a one-standard-deviation increase in the K-to-N ratio can lead to a 16% increase in rice yields, significantly higher than estimates derived from ordinary least squares (OLS) methods [53][54]. - While yield increases are evident, the report notes that the impact on farmer revenue is less clear, potentially due to measurement errors and market dynamics affecting prices [55][56]. Conclusion - The conclusion underscores the potential for policy interventions aimed at optimizing fertilizer use to enhance agricultural productivity, suggesting that improving farmers' knowledge about nutrient diversity could be a cost-effective strategy [64][65].
