Abstract
Results of the study revealed significant growth and yield response to both cultivation and fertilizer application. Plant population density showed no appreciable influence on either growth and yield, including the other agronomic variables observed.
Furthermore, regardless of plant population density, fertilized sunflower on properly cultivated land, exhibited better growth, produced bigger heads, heavier seeds and consequently higher yield. Percentage filled seeds and the ratio of husk to kernel were not affected by cultivation and plant population but were influenced markedly by fertilizer application.
When plants were availed of both cultivation and fertilizer, yield was further improved, indicating that these two factors had beneficial effects.
