Effect of Different Seed-sizes on the Yield and Some Quantitative Characters of Sunflower (Helianthus annuus L.)

Abstract

A study was conducted to understand the effect of different seed-sizes on quanti. tative characters like plant-height, girth of stem. number of leaves, days to flower. days to maturity, diameter of head, yield per plant. yield/ha, shelling percentage and 100 seed weight. Significant differences were observed for all the ten characters studied. The largest seeds had more plant height. stem girth, number of leaves. head diameter. shelling percentage 100 seed-weight, yield per plant and yield per hectare. The plants grown from largest seeds flowered and matured earlier. The present study revealed that graded and bold seeds should be used for obtaining maximum yield.
