Head Size of Sunflower as an Indicator of Plot Yields¹

The accuracy of plot yields of sunflower is often reduced by bird depredation. To find a substitute for harvested yields of plots, the head size of two varieties of sunflower was correlated with yield per head. The high correlation obtained (r = 0.95) indicates that, in plots which have considerable bird damage, yield estimates based on head size would be more accurate than actual seed weights.

Key Words: Sunflower • Helianthus annuus L. • Seed yield • Seed size
