Abstract:
A field experiment was carried out during the Zaid season of 2021 at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences (SHUATS), Prayagraj (U.P.). Foliar application of different micronutrients (zinc, iron and boron) either single or with combinations were applied. The experiment was laid out in Randomized Block Design with eight treatments replicated thrice. The application of treatment NPK + B @ (0.3%) + Zn @ (0.5%) was found significantly higher in Plant height (223.53 cm), dry weight (59.67 g/plant) and crop growth rate (14.14 g/m2/plant), as compared to other treatments. Maximum number of seed yield (1036.67 kg/ha), stover yield (28.91 t/ha) and test weight (37.33 g) were found significantly higher with the application of treatment NPK + B @ (0.3%) + Zn @ (0.5%). Maximum Gross return (1,03,933 ₹/ha), Net return (80,736.35 ₹/ha) and B: C ratio (3.48) were recorded in treatment with application of treatment NPK + B @ (0.3%) + Zn @ (0.5%). From the findings of present study, it is concluded that application of Treatment No. 7: NPK + B @ (0.3%) + Zn @ (0.5%) as compared to other treatments among all other treatments has given the best results for growth and yield of sunflower. Therefore, application of NPK + B @ (0.3%) + Zn @ (0.5%) will improve growth and yield of sunflower as a result of which the growers will be economically benefited.
