Abstract: Maximizing onion (Allium cepa L.) seed production through foliar application of zinc and boron in Swat Valley at Agricultural Research Institute Mingora-Swat, Pakistan was executed during 2013-14.The onion bulbs of cv.Swat-1 were used as planting material.NPK applied @ 120:60:60 kg/ha as urea, di-ammonium phosphate and potassium sulphate, respectively, while zinc was applied @ 0, 0.3, 0.7 kg/ha as heptahydrated zinc sulphate (ZnSO4.7H2O)and 0, 0.1, 0.3 kg/ha boron in the form of borax (H3BO3).Randomized complete block design was used for the experiment with factorial arrangement and replicated 3 times.3 ´ 4 m was the plot size.Results revealed that both zinc and boron significantly affected all the parameters under studied.However, maximum number of leaves/plant, maximum number of flowers/plant, maximum seeds/umbel, maximum seed weight/umbel and maximum seed yield were recorded by the combined application of Zn and B at 0.7 and 0.3 kg/ha, respectively.Moreover, maximum concentration of zinc in seeds were found in treatment plots where Zn @ 0.7 kg/ha and B @ 0.3 kg/ha were applied simultaneously.Zinc-boron concentration in leaves at flowering stage and in seeds at harvest showed significant positive linear relationship to each other.The results suggested that maximum onion seeds yield under the condition of the experiment were produced when 0.7 kg/ha Zn and 0.3 kg/ha boron were applied.
