The Effect of Iron foliar Nutrition to reduce Salinity Stress effect in some anatomical traits and Yield components of maiz ( Zea Mays L. )

Abstract

A field experiment was conducted during the fall season of 2015 in The Najaf Ashraf governorate by using different Concentration of NaCl ( 0 , 2 , 4 , 6 ds.m-1 ) Three concentration of iron Fe ( 0 , 1000 , 2000 ppm ) in the aim of studing the effect of foliar nutrition by iron to reduce the impact of harmal salts in some anatomical traits and some of yeild components maize. From this study it was concluded that the element of iron had effective role in reducing the impact of salinity, especially in the concentricity 1000 ppm which reduce the effect of salinity and increase the production in quantity and quality by increasing the values siqnificantly in length of earn , The numbers of rows in the earn and weight of one hundred grains in (g) . In addition to that the salinity in irrigtion water led to decrease in the number of stomata , increasing the length and width of the lower epidermis of the leaf cell , thickness of the cortex and the number of air spaces in the roots of the plant.
