Abstract
Studies were undertaken to evaluate the response of autumn planted sunflower (Helianthus annuus L.) hybrids to
different planting patterns at the Agronomic Research Farm, University of Agriculture, Faisalabad during, 2004
and 2005. Treatments comprised of two hybrids (FH-314 and FH-245) grown under six different planting patterns
viz., 60 x 15 cm, 60 x 22.5 cm, 60 x 30 cm, 75 x 15 cm, 75 x 22.5 cm, & 75 x 30 cm. Data collected on achene
yield and yield components were subjected to standard statistical analysis. The average data showed that hybrid
FH-314 produced significantly higher achene yield (2487.24 kg ha-1) than that of FH-245. The highest achene
yield (2821.89 kg ha-1) was obtained when the crop was sown with the planting pattern of 60 cm x 22.5 cm.
