Field experiments were conducted at Tamil Nadu Agricultural University, Coimbatore during winter 2016 and summer 2017, to study seasonal variation on phenology and productivity of groundnut (Arachis hypogaea) along with red gram (Cajanus cajan), maize (Zea mays) and castor (Ricinus communis) as intercrop at different irrigation levels. Groundnut pod yield was higher under winter season (2214 kg ha-1) against summer (2033 kg ha-1). The microclimate parameters like leaf temperature, canopy temperature, soil surface temperature and the soil temperature were higher during summer as compared to winter. Harvest index of 0.34 noticed during summer, it was found that the harvest index was 0.50 during winter.
