A field experiment was conducted during Kharif season 2021 at Dryland Farm, S.V. Agricultural College, Tirupati, Andhra Pradesh, ANGRAU. To know the effect of weather parameters on proso millet crop under three dates of sowing i.e. first fortnight of June (D1), second fortnight of June (D2) and first fortnight of July (D3) and three varieties i.e. CO 5 (V1), TNAU 202 (V2) and GPUP 8 (V3) with three replications. Proso millet sown on I FN (* first fortnight) of June and variety GPUP 8 utilized more Growing Degree Days, Photothermal Units and Heat Use Efficiency compared to II FN of June and I FN of July. Among the three sowing windows crops sown in II FN of June (D2) and cultivar, CO 5 (V1) produced significantly higher straw yield, total dry matter, grain yield and monetary returns.
