Abstract

Crop phenology and yield are highly influenced by prevailing weather condition during the crop growth phases. A research work was carried out at Agro Climate Research Centre, Tamil Nadu Agricultural University, Coimbatore during June to August 2022 to determine the suitable sowing window for Greengram. The field experiment was laid out in CO 8 Greengram variety with two sowing windows of D1 - 15 June 2022 (24th SMW) and D2 - 22 June 2022 (25th SMW). The best time of sowing was established by using Growing Degree Days (GDD), Helio thermal Units (HTU), Photo thermal Units (PTU) and Heat Use Efficiency (HUE). The study revealed that the 25th Standard Meteorological week (SMW) recorded higher yield due to higher values of GDD, HTU, PTU and HUE at different crop growth stages.
