Abstract:
The desired goal of this investigation was to study the effect of eight micronutrients foliar application [Zn, Fe, Mn, Zn + Fe, Zn + Mn, Fe + Mn, Zn + Fe + Mn and control (tap water)] and three potassium fertilizer levels (check, 24 and 48 kg K2O/fad.) on yield, their attributes and seed quality of sesame grown in sandy soil. The obtained results revealed that, foliar application of Zn + Fe + Mn led to a significant increase in most yield attributes, seed and oil yields/fad., as well as seed oil % during both seasons. Plant height, fruiting zone length, No. capsules per plant, No. and weight of seeds per capsule, weight of seeds per plant and 1000-seed weight, seed and oil yields/fad., as well as, seed oil % exhibited significant increase due to raising K level up to 48 kg K2O/fad. It could be concluded that foliar application of Zn + Mn or Zn + Fe + Mn along with 48 kg K2O/fad., produced the highest sesame seed and oil yields/fad
