Present investigation entitled “Impact of weather parameters on yield of kharif sunflower (Helianthus annuus L.) Under different growing environments in scarcity zone of Maharashtra.” was carried out during 2013-17 at Zonal Agricultural Research Station, Solapur, Maharashtra State (India). The experiment was conducted in split plot design with three replications. Nine treatment combinations were formed considering different cultivars viz., V1 Bhanu, V2 MSFH-1 and V3 Phule Bhaskar and sowing windows viz., (S1) 2nd fortnight of June (25th-June), (S2)- 2nd fortnight of July (27th-July) S3-2nd fortnight of August (24th-August). Among the three pearl millet sowing window crop sown in second fortnight of July (S2) produced significantly highest grain yield (1708.2 kg ha-1) and total monetary returns (56320 kg ha-1), (CUM) (320 mm), (MUE) (5.3 Kg ha-1 mm), (GDD) (10420 days) , total dry matter (400.8 g m-2), LAI and RUE July (1.31 & 1.63 g MJ-1) than other dates of sowing. Among the genotypes Phule Bhaskar produced significantly higher grain yield (1446.8 kg ha-1), total monetary returns (Rs. 47590 ha-1), CUM (293.1 mm), MUE (4.8 Kg ha-1 mm), mean number of days to attain physiological stages (92 days), GDD (8460 days), mean total dry matter (404.1 g m-2) than other cultivars. The correlation study revealed that the wind speed had significant positive correlation at emergence phase (P1) and 3 leaf stage (P2). Tmax had significant positive influence and RH-1, RH-II and RF has significant negative influence at button phase (P3).
