Abstract

, An experiment conducted at New Delhi on spring sunflower (Helianfhus annuus L.) during 1994 and 1995 revealed that low temperatures during early growth phase of the crop, sown in the third week of January delayed the germination and subsequent phenological stages. Crop sown in the 2nd week of February recorded better yield attributes and gave higher seed and oil yield. Crop sown in the wider spacing (75 x 30 cm) produced better yield attributes. However, higher seed and oil yields were recorded at 50 x 30 cm crop geometry.
