12 pages., Purpose
Pervasive use of poor quality seed remains an important reason for low yields throughout the developing world. We explore ways to increase the quality of the local stock of seed tubers among a sample of Ugandan potato farmers.
Design/methodology/approach: Using videos, we provide agricultural extension information on (i) how to select the best seed tubers and (ii) how to properly handle and store seed tubers until the next planting season. The relative effectiveness of the information interventions is tested using an individually randomized controlled trial where we model spillovers using a randomization-based framework for estimating causal effects under interference between units.
Findings: Especially the video on seed selection translated into increased awareness and adoption of recommended practices, increased probability of using improved inputs, as well as higher consumption.
Practical implications: Interventions aimed at improving seed quality are important in the absence of access to high-quality seed. Video messages are becoming increasingly useful as a complementary tool in agricultural extension.
Theoretical implications: Randomization-based inference can be used to take into account spillover effects in the analysis rather than the design phase of an experiment.
Originality/value: This is the first study to address seed quality of potato tubers in a real-world setting using videos.
Agricultural Economics (Amsterdam, Netherlands), The study aims to track adoption of improved chickpea varieties, and assess their on-farm benefits in some remote and backward tribal villages in Gujarat, India, where few newly developed varieties were introduced by a non-government organization. It also determines key factors which were influencing their adoption. The study found that adoption of improved chickpea varieties was gradually increasing by replacing a prominent local variety. Duration of crop maturity, farm size, yield risk, and farmers' experience of growing chickpea crop were significantly influencing their adoption. The on-farm benefits as a result of improved varieties were realized in terms of increased yield levels, higher income and labor productivity, more marketable surplus, price premium and stabilized yields in fluctuating weather. Breeding short duration varieties with stable yield levels under varying weather, and organizing seed multiplication and dissemination in regions, where moisture stress is a problem during maturity of chickpea, are the major suggestions.
