Abstract
The experiment was conducted at crop research farm in Department of Agronomy during Rabi, 2022 on sunflower crop. The treatment consisted of 3 levels of foliar application of zinc (10 kg/ha, 0.5%, 10 kg/ha + 0.25%) and foliar application of boron (3 kg/ha, 0.3%, 3 kg/ha + 0.15%) and control (80,40,40 kg/ha). The experiment was laid out in Randomized Block Design with 10 treatments and replicated thrice. Foliar application of Zinc at 10 kg/ha + 0.25% with foliar application of Boron at 3 kg/ha + 0.15% recorded maximum plant height (122.58 cm), Plant dry weight (46.82 g/plant), head diameter (19.20), Seeds/capitulum (311.59), Test weight (53.92 g), Seed yield (1.79 t/ha), stalk yield (4.31 t/ha), Harvest index (29.35 %), gross returns (Rs.1,07,472.00/ha) and net return (Rs.74,608.00/ha). Maximum Benefit Cost Ratio (2.27) was also recorded in the same treatment no. 9 in sunflower crop.
