تأثير رش مستويات مختلفة من الحديد و الزنك في نمو و حاصل الشعير Hordeum vulgare L. تحت ظروف منطقة البصرة

Abstract EN

Field experiment was conducted during growing search of–year 2012 to determined three levels of concentration 0 , 50 and 100 mg / L of each of Fe and Zn on growth and yield of barely .

Time of application were twice the first time was applied after 30 days after planting and the second at flowering stage .

A factorial Experiment in R.C.B.D was used .

The results showed that there significant response in leave area , no.

of spikes / m2, no.

of seed / spike, 1000 seed weight and grain yield when Fe and Zn applied compared to the control .

Application on of 100 mg / L Fe.

The highest Fe level gave the highest seed yield ( 3.362 tan / ha ) , similar result was found by application of Zn (3.031 t / ha) .

The interaction of Zn and Fe was significant on all traits under the study and application of 100 mg / L of Fe and 100 mg / L of Zn gave the highest values.
