摘要

社会经济影响是基于2021/2022年间在泰米尔纳德邦Tenkasi和Tirunelveli地区对200名中国马铃薯生产商进行的农户调查得出的。采用logistic回归模型识别决定采用“SreeDhara”的因素,并采用逆概率加权回归调整(IPWRA)方法评估采用“SreeDhara”对产量和收入的影响。“SreeDhara”收养者的种植成本、总收入和净收入分别比非收养者高7%、37%和87%。受教育年限、农场收入、获得推广服务的机会和块假对采用该品种有显著的积极影响。IPWRA结果显示,“SreeDhara”采用者的产量和收入分别比非采用者高23.65%和24.99%。种植中国土豆的最大制约因素是缺乏对“sredhara”的认识,难以获得信贷,以及无法获得作物保险。因此,认识到其较高的营养价值和潜在的农业收入,需要加强以更好的推广联系、信贷设施和作物保险形式向中国马铃薯种植者提供的机构支持。

Socioeconomic impact of improved variety of Chinese potato in Tamil Nadu
The socioeconomic impact was based on a farm household survey conducted in Tenkasi and Tirunelveli districts of Tamil Nadu among 200 Chinese potato producers during 2021/2022. A logistic regression model was employed to identify factors determining the adoption of ‘SreeDhara’, and the Inverse Probability Weighted Regression Adjustment (IPWRA) method was used to assess the impact of the adoption of ‘SreeDhara’ on yield and income. The cost of cultivation, gross income, and net income for ‘SreeDhara’ adopters were 7, 37, and 87% higher than for non-adopters. Years of schooling, farm income, access to extension services, and block dummies had significant, positive effects on adopting the variety. The IPWRA results indicated yield and income of ‘SreeDhara’ adopters were higher than non-adopters by 23.65 and 24.99 %, respectively. The most significant constraints to adopting Chinese potatoes were lack of awareness about ‘SreeDhara,’ inaccessibility to credit, and the non-availability of crop insurance. Thus, recognizing its higher nutritional value and potential farm income, institutional support in the form of better extension linkages, credit facilities, and crop insurance to Chinese potato growers needs to be strengthened.
