Abstract
To investigate the effect of some micronutrients application and bio- stimulants on
growth, productivity, chemical compositions and quality of wheat. Two field experiment
were conducted at farm in Rosetta zone El- Behera during 2017/2018 and 2018/2019 growing
seasons.
A split plot design with three replicates was used. The treatments can be illustrated
as follows:
Main plots (Foliar application of micronutrients) were as follows
▪ Control (water).
▪ One spray of Zn + Fe + Mn (600 g/fed) at 25 DAS.
▪ Twice spray of Zn + Fe + Mn (600 g/fed/time).
While sub-plots (bio- stimulants) were as follows
T0 Control.
T1 Foliar application of Butyric acid at concentration of 2% at the rate of 100 g/fed.
T2 Soil application of butyric acid at concentration of 2% at the rate of 100 g/fed.
T3 Foliar application of fulvic acid at concentration of 70 % at the rate of 500 g/fed.
T4 Soil application of fulvic acid at concentration of 70 % at the rate of 500 g/fed.
T5 Foliar application of butyric acid (100 g/fed) + fulvic acid (500 g/fed).
T6 Soil application of butyric acid (100 g/fed) + fulvic acid (500 g/fed).
All cultural practices for growing wheat were applied uniformly as recommended.
