Association Sunflower seed yield per head was higher in Serbia than India.
Association Sunflower 1,000-seed weight was larger in Serbia than India.
Observation Ha-121 had the highest seed yield per head.
Association Yield rose gradually to the midpoint of the harvest period.
Intervention effect Only the first three harvest dates gave significantly lower yields than later dates.
Observation Ha-121 had the largest average 1,000-seed weight.
