تأثير رش تراكيز مختلفة من نانو الحديد المخلبي و الجبرلين و السماد العضوي (أكاديان)‎ في محتوى العناصر الكبرى لأوراق نبات المورينجا Moringa oleifera Lam.

Abstract EN

An experiment was conducted by using pots that contain 20 kg soil during the summer season of 2016-2017 in the Department of Biology/ College of Education/AL–Qadisiya University.

To study the effect of foliar application of nano chelated iron, GA3 and organic fertilizer (Acadian) in macronutrients content (N, P, K, Ca and Mg) in leaves of Moringa oleifera Lam.

Using sandy mixed soil.

The factorial experiment was designed by Randomized Complete Blocks Design (RCBD) with three replicate, included five spray concentrations of nano chelated iron (0, 1, 2, 3 and 4) g.L-1 , three concentrations of GA3 (0, 200 and 400) mg.L-1 and with or without Acadian fertilizer (0,1) g.L-1 and their interaction.

After five months from seeds germination date, the mineral content were measured.

Means were compared by using Least Significant Differences (LSD) at 0.05 probability level.

Results showed that: Concentration of 2g.L-1 of nano-chelated iron achieved the highest percentage of N, P, K and Ca.

While the concentration of 1g.L-1 was superior in Mg leaf content.

The highest concentration of N, P, K, and Ca was obtained by GA3 at 200 mg.L-1.

Whilst the effect of GA3 was negative on the percentage of Mg.

Organic fertilizer had a positive effect on the increase in percentage of N, P, K, Ca and Mg.

Triple intraction of the study factors showed a significant increase for most of the studied traits, especially the combination of 2g.L-1 nano-chelated iron with 200 mg.L-1 GA3 with the use of organic fertilizer.
