Boron deficiency is second most dominant micronutrient problem around the world and it is an important micronutrient required for plant growth and development. So a field study was conducted to explore the potential of boron seed priming on yield and quality of sunflower hybrids at Agronomic Research Farm, University of Agriculture, Faisalabad. The achenes of two different sunflower hybrids i.e. Hysun-33 and FH-331 were subjected to different priming treatments including hydropriming, osmopriming (with 1, 0.1 and 0.01 mM B) using boric acid as a source of B. The experiment was laid out in randomized complete block design with factorial arrangement in triplicate run. Results from the experiment revealed that all the seed treatments significantly improved achene yield, yield attributes and oil contents of sunflower. However, seed priming with 1 mM B solution was the best treatment in improving achene yield and oil contents of sunflower hybrid. While in case of hybrids HYSUN-33 performed significantly better than FH-331 for all studied parameters except for oil contents. However, the interaction between sunflower hybrids and seed priming treatments was non-significant for most of the traits.
