While seasonality in the consumer demand and producer supply of agricultural commodities is well understood, relatively little is known regarding seasonal variation in the adoption of farm technologies, such as hybrid seeds, whose effectiveness may vary across seasons.  Hybrid seed adoption studies in developing countries tend to suffer from a problem of temporal aggregation where data is either (1) measured in a snapshot of time, in which case seasonal variation cannot be analysed, or; (2) aggregated over the course of a year or multiple years, where cyclical seasonal variation is washed out. This study will uncover the seasonal dynamics in hybrid seed demand by analysing the case of Chili in Indonesia, which is an important commodity that is produced all year long despite seasonal variation. However, there appear to be significant seasonal bottlenecks in input markets and identifying seasonal change in hybrid seed use by farmers will be critical for improving the functioning of the seed-system. In analysis, factor demand functions will be estimated using a unique dataset of 251 chili producers. The study will test for structural change in the demand for hybrid seeds going from dry season to wet season and identify season specific constraints to hybrid seed use. Results will inform the seed research program and seed value-chains on seasonal constraints or demand for seed attributes that are important for farmers. This can improve targeting of hybrid seed diffusion programs that tend to be uniform across seasons.
