Varietal turnover in potato and its effect on yield: Evidence from household surveys in India

Potato remains a crucial crop for achieving India’s food security goals and generating income for small-scale farmers. But India, the largest potato producer after China, remains behind many of its peers in attaining high yield. A low varietal replacement rate could be one of the major reasons for low yield in India. This critical issue warrants investigation, yet empirical results remain limited in the Indian context. Drawing on data from a comprehensive field survey of 892 potato growing farmers conducted in 2018–19 across five major potato-producing states in India, we find the determinants of the average area-weighted age of potato varieties used, and their impact on potato yield. The instrumental variable regression analysis establishes a negative association between varietal age and yield of potato. It also underscores the importance of access to weather forecast and linkages with agricultural organizations to achieve higher yield. Furthermore, it shows that household size, links to political party, and information about new seeds from friends, progressive farmers and input dealers are associated with lower varietal age. These insights will be instrumental for policymakers and potato breeders in promoting sustainable agricultural practices and boosting food security in India amidst the impending demographic challenges.

Welfare implications of public expenditure in Indian agriculture: New evidence from CS-ARDL Approach

This study explores the welfare implications of public expenditure at the subnational level. We empirically examine the efficiency of different categories of public expenditure on agriculture and irrigation using the novel cross-sectional autoregressive distributed lag (CS-ARDL) model and the data from 1981 to 2019 for 17 major agricultural states of India. The findings reveal the strong long-term positive effect in rural India of public sector expenditure on crop husbandry, agricultural research and education, soil and water conservation, irrigation, food storage and warehousing, animal husbandry and dairy development, and fisheries on total factor productivity (TFP), farm income, and poverty alleviation. Irrigation and electricity subsidies do not significantly affect outcome variables, while fertilizer subsidies showed a long-term negative impact on TFP, and credit subsidies had a positive effect on income and on the reduction of rural poverty. Other factors that were shown to have welfare implications included rainfall, literacy rate, and agricultural terms of trade (TOT), that is, the ratio of agriculture GDP to non-agriculture GDP. Policymakers should thus better target and rationalize government expenditure programs by removing unproductive input subsidies and reallocating those funds toward other types of public investment in Indian agriculture.
