Abstract
Results revealed that no significant difference exists between varieties. The different levels of complete fertilizer and the interaction between distance and levels of fertilizer were significant on diameter of head. The distance of 15 centimeters between hills exhibited significantly better growth increment, weight of seed/plot, with better oil content both actual and dry basis. At lower population rate the head size increased correspondingly with considerable increase in the weight of 100 seed andweight of seed per head. However, distance of 15 centimeters gave the highest yield.
