Abstract:
An present field experiment was conducted at the post graduate Research farm, Agronomy section, RCSM College of Agriculture, Kolhapur (MH), India. During March to April 2020 to investigate the effect of fertilizer levels and plant densities on growth attribute and yield of summer sunflower (Helianthus annuus L.). The experiment comprised three fertilizer levels viz, 45:45:45, 60:60:60 and 75:75:75 NPK kg ha-1 and three plant densities viz, 30 cm x 30 cm, 45 cm x 30 cm and 60 cm x 30 cm. The experiment was laid out in Factorial randomized block design with four replication. Result revealed that fertilizer levels and plant densities had significant effect on yield attribute and yield of summer sunflower. The yield character and yield viz, diameter of disk -1(cm), number of seed disc-1, weight of seed disc-1 (g), 100 seed weight (g), seed yield, stalk yield and biological yield (q ha-1) was recorded higher by application of fertilizer levels 75:75:75 kg NPK ha-1. All the character were recorded higher under plant density (60 cm x 30 cm). except stalk yield and biological yield. The highest stalk yield and biological yield was recorded in (45 cm x 30 cm).
