Abstract:

Baby corn is the ear and diversified product of maize plant harvested young, especially when the silks have either not emerged or just emerged, and no fertilization has taken place. Field experiments were conducted during October-March, 2012-13 and 2013-14to study the impacts of thermal regime on phenology and yield of baby corn. Thermal environment during reproductive phase of baby corn contributed more towards the yield formation process, as compared to that during vegetative phases. Among yield components, ear diameter showed consistently negative correlation with thermal environment whereas cob and fodder yield showed consistently positive correlation with the thermal environment. Among weather variables during vegetative stage, maximum temperature was found to be best indicator of cob yield. The difference in heat use efficiency (HUE) values among the dates of sowing was statistically significant. Baby corn sown at 15th February recorded highest HUE vis-a-vis baby corn yield, which might be associated with the exposure of average maximum temperature beyond 35oC that favoured the crop yield level to its maximum. The growth and yield parameters of baby corn are clearly indicative that they are thermo- sensitive and the crop performs better at higher thermal regimes.
