Abstract:
An experiment was conducted at the College of Agriculture, Vellayani to
study the effect of different spacings on the yield of sunflower varieties. The
results revealed that closer spacing decreased the head diameter and number of
seeds per head, but significantly increased the total yield of seed. Closer spacing
of 30x20 cm gave a maximum yield of 2163.1 kg seeds per hectare. The varieties
did not show any difference in yield potential.
