Impact of micronutrients foliar appliction and potassium fertilizer levels on productivity and quality of sesame under sandy soil conditions

Abstract EN

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.
