Abstract
A field trial was conducted to compare the performance of sunflower varieties under different fertility regims had significant influence on days to flowering, days to maturity, plant height, head diameter, seeds per head, seed index and seed yield, while treatment interactions exposed non-significant influence on all the growth and yield components except plant height. Varieties Ho-1 and Cargll-206 with the fertility regime 120-45 kg N-O/ha produced late flowering and maturity in tall plants, maximum head diameter, seed per head, seed index and seed yield per hectare. Among the tested varieties Ho-1 and Cargil-206 seemed to be better fertilizer responsive and performed well under higher fertility regimes. It was deduced that Ho-1 and Cargil-206 could be satisfactory high yielders if supplied with 120-45 kg N-P per hectare.
