Abstract


A pot experiment was conducted in the year 2016 to evaluate the effect of seed size and burial depth of sunflower on the germination, growth and some yield components. The experiment was laid in a split plot design with seed size as main plot and burial depth as sub-plot with three replicates. The results indicated that seed size had significant effect on germination, plant height, number of leaves, leaf area, number of seeds per plant. The analysis indicated that there was no significant effect for seed size on head diameter, head weight and seed weight. A significant difference was observed between the burial depth, and the interaction between seed size and burial depth showed significant effect.


Keywords
