تأثير التسميد الورقي ببعض المغذيات الصغرى على (Triticum aestivum L.)‎ نمو وإنتاجية القم

الملخص EN

This experiment was conducted in pots to study the effects of foliar application of microelements (Cu, Zn and Fe) on some morphological, physiological and productivity characters of wheat (Ibaa cultivar).

The experiment contained the following treatments: control (T1), iron sulfate (T2), zinc sulfate (T3), copper sulfate (T4), iron + zinc (T5), iron + copper (T6), zinc + copper (T7) and iron + zinc + copper (T8).

All microelement treatments showed significant increase in all morphological, physiological and productivity characters compared with the control treatment.

T8 treatment gave significant increase as compared to other treatments in all morphological characters (height of plant, leaf number, leaf area, branch number, total dry weight for shoots and roots).

It gave increases by 11.4, 38.5, 28.3, 38, 38.1 and 109 %, respectively compared with the control.

The T8 treatment also gave significant values in all physiological characters (chlorophyll, concentrations of N, P, K, Fe, Zn, Cu, starch and protein in grains) as compared to other treatments and the control treatment except with treatment T7, where there was no significant difference in P % and Fe % in grains.

T8 gave increases in grain yield, protein and starch in grains by 71, 63 and 11 %, respectively compared to the control treatment.

It is concluded that wheat cultivar (Ibaa) gave a clear response to foliar application with microelements Fe, Zn and Cu.

Treatments of combinations between two elements together came second while treatments with each element alone came third.

The results gave an indicator to use more than one element in foliar application in many bathes under a sprinkler irrigation system
