The Effect of Foliar Spray with Managanes and Elements and Bio-Fertilization of Some of the Elements Absorption of Wheat Plant (Triticum aestivum L.)

Abstract

A pot experiment was conducted in the autumn season 2019/2020 in a wire-house  sunshade / the Technical College / Al-Mussaib, the experiment factors include: three levels of Manganese (0,40,80)  mgm Mn.L^-1 symbolized as (Mn₀,Mn₁,Mn₂) respectively , three levels of copper (0,10,20) mgm Cu.L^-1 symbolized as (Cu₀,Cu₁,Cu₂) respectively , and  two levels of biological fertilization (with and without) symbolized as (B.F₀ , B.F₁), the results showed that manganese spray when concentrating (80 mg .Mn L^-1 ) to a significant increase in all the studied parameters, including plant height as it increased from(76.83  to 83.55 cm), flag leaf area as it increased from (31.05 to 36.41  cm²)  , dry matter weight as it increased from (13.71  to 16.51 gm), manganese concentration in leaves as it increased from(706.47 to 750.86  µg.gm^-1)  ,and copper concentration in leaves as it increased from(4.25 to5.60 µg.gm^-1)  , also spraying with copper at a concentration of (10 mg .Cu L^-1 ) to a significant increase in all the studied parameters , including plant height as it increased from(77.42 to 82.88 cm),  area of the flag leaves as it increased from(31.95 to 35.70 cm²)  , dry matter weight as it increased from (13.86 to 16.98 gm) , manganese concentration in leaves as it increased from (699.33 to 759.61 µg.gm^-1) ,and copper concentration in leaves as it increased from (4.55 to 5.20 µg.gm^-1), also the addition of biological fertilizer significantly affected all the studied parameters, including plant height as it increased from (75.39  to78.96 cm), flag leaf area as it increased from (31.71 to 32.62 cm²) ,dry matter weight as it increased from (14.39 to 15.00 gm) , manganese concentration in leaves as it increased from (699.03 to 712.91 µg.gm^-1)  , and copper concentration in leaves as it increased from (4.12 to 4.35 µg.gm^-1).
