The effects of four sowing dates (9th June, 23rd June, 12th July and 28th July) and six intra-row spacings (15, 20,25,30,35 and 40 cm) on sunflower performance were studied for two years in the Nigerian savanna. Sowing date was found to have significantly affected plant height at flowering in both yean. However, sowing date significantly affected grain yield in 1987 and the number of days to first flowering in 1988. Intra-row spacing significantly affected grain yield in both years and the number of days to first flowering in 1988. The interactions between the sowing dates and the intra-row spacings were significant for grain yield in 1987 and for plant height at flowering in 1988. sowing from the last week of June to the second week of July at intra-row spacings between 25 and 30 cm gave highest grain yietds.
