The growth and yield of five genotypes of sunflower (Helianthus annuus L.) in the lowland of West Sumatra, Indonesia

Abstract Sunflower plants have many benefits as food, especially for vegetable oil. The development of sunflower cultivation in Indonesia has not been optimal, production. Increasing production requires superior seeds. Therefore, it is necessary to conduct field tests know the growth and yield lowlands before plant assembly. objective this study was determine five adaptive genotypes. research conducted July - September 2022 Pauh Sub-district, Padang City, West Sumatra Province genotypes were Ha1, Ha15, HU1, HU2, HU3. observed variables height, stem diameter, flowering age, main flower weight 100 seeds, percentage empty used a Completely Randomized Block Design data analysis by variance if F test on shows significant effect, then continued with Duncan’s Multiple Range Test at 5%The results showed that had effect According variable, HU3, HU1 more than others.
