These investigations were conducted to study the influence of N and K drip fertigation along with boron foliar spray on growth, seed yield and seed quality of onion (Allium cepa L.). The experiments were carried out during two consecutive years (2014-15 and 2015-16) at experimental farm of Department of Seed Science and Technology, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan-173230 (H.P) using randomised block design. N and K fertilizers were applied through drip irrigation at three different levels viz; 100 %, 80 % and 60 % of RDF as twenty different combinations in 10 equal splits at 15 days interval along with boron foliar spray. The results revealed that N and K fertigation along with boron foliar spray treatments gave significant results on plant growth, seed yield and quality parameters. Among all the treatments N100K100B1 (48.34 cm) exhibited maximum plant height, minimum days to 50 % flowering (151.00), number of flowering stalks per plant (7.73), number of umbels per plant (5.72), number of umblets per umbel (992.50), number of seeds/umbel (5143.27), seed yield /hectare (862.07), 1000 seed weight (4.39 g), germination %age (96.00 %), seedling length (15.18 cm), seedling dry weight (20.42 mg) and seedling vigour index I and II (1456.99 and 1961.01).
