A field experiment was conducted for two years to study the effect of planting time on plant growth, biomass yield, oil yield and quality of spearmint oil (M. spicata L.) in central Uttar Pradesh. Maximum biomass yield (27,500 kg/ha) and oil yield (175.4 kg/ha) were obtained from crop planted on December 30 which was due to better crop growth in terms of plant height, leaf area index, dry matter accumulation and oil content. The quality of oil as assessed by carvone content in oil was higher in November-December plantings compared to late plantings. Planting of spearmint in second half of December is recommended under the agro-climatic conditions of Central Uttar Pradesh.
