| 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 andcontrol (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 ofZn + 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 seedsper plant and 1000-seed weight, seed and oil yields/fad., as well as, seed oil % exhibited significant increase due to raisingK level up to 48 kg K2O/fad. It could be concluded that foliar application of Zn+MnorZn + Fe + Mn along with 48 kg K2O/fad.,produced the highestsesame seed and oil yields/fad. | ||
