INTER‐REGIONAL VARIATION IN THE SPEED OF ADOPTION OF MODERN CEREAL CULTIVARS IN INDIA
研究了印度现代谷物品种采用速度及其区域差异，发现盈利性和生产风险能解释小麦和水稻的采用速度，但无法充分解释高粱、珍珠粟和玉米的采用情况。
Speed of adoption of modern cereal cultivars in India is measured and its inter‐regional variation is investigated. Adoption speed varies widely across regions and between cereals. While profitability and production risk have been important determinants of adoption speed of high‐yielding wheat and rice varieties, such factors fail to explain adequately the uptake of modern cultivars of sorghum, pearl millet and maize. A comparison with the results of other studies confirms the responsiveness of Indian farmers to economic opportunities.
