Effect of High Concentration of Fe and Mn as Foliar Application on Growth and Yield of Sesame Grown in Calcareous Soil

A farmer field trial experiment was conducted at growth season of 2016 in Deraluk sub-district, Amadiya district, Dohuk province, Iraq to investigate the effect of foliar application of high level of Fe and Mn on growth and yield of sesame (Sesamum indicum L. ) grown in calcareous soil. A concentration of 0.5 % of the micronutrients Fe, Mn and Fe + Mn was used as a foliar application in two splits: The first split was just before anthesis (40DAS) and the second split was after full anthesis (65DAS). The results showed no significant reduction in all studied parameters which included plant highs, number of capsules, the weight of 1000 seeds, grain yield and Straw yield (except the treatments Fe and Fe+Mn they were significantly reduced from the control). No significant values of (HI) were found between the treatments despite the superiority of Mn and Fe+Mn over the control.
