Abstract: A field experiment was conducted at Annamalai university experimental farm Chidambaram during kharif 2014 to study the effect of micro nutrient management in hybrid sunflower on growth and yield. Application of 150% RDF (60:90:60 kg NPK ha-1) along with micro nutrient @250 g ha-1 at 25 &45 days after sowing, recorded higher plant height (64.88, 145.26 and 166.24) at 30,60 and harvest stage, respectively over control. Similar trends was also noticed in days to 50 per cent flowering (56.05), early where notice application of 150 per cent RDF +foliar spray of micro nutrient @250 g ha-1 at 25 &45 days after sowing, recorded higher yield attributes and yield data like capitulum-1 diameter (20.85 cm), total number of seeds for capitulum-1, (1040.96) filled seeds for capitulum-1 (925.25), per Cent of filled seed for capitulum-1 (88.88), test weight (5.9), seed yield (2195.3 kg ha-1), stalk yield (3556.3 kg ha-1) and harvest index (38.16 %) over control. The quality parameters were also recorded significant higher oil content (43 %) and oil yield (943.97 kg ha-1) over control. And benefit cost ratio (3.12) recorded. Following with 125 % RDF + foliar spray of micro nutrient @ 250 g ha-1 at 25 and 45 days after sowing.
