استجابة نمو و نوعية حاصل ثلاثة اصناف من الذرة الصفراء للرش بالمحفز الحيوي Triplex Amino

الملخص EN

Two field experiment were carried out in the spring and autumn lugs of 2019 in Abu Gharib research station of the Agricultural Research Department / Ministry of Agriculture.

To know the response of growth, yield and quality of maize to spraying with bio-stimulator.

The experiment was applied in the order of split - plot according to the design of RCBD with three replications.

The main plot included four concentrations of Triplex amino (0, 3, 6, 9) gm.

L-1, While the secondary plot included three varietiesof maize (Sarah, Fajr1 and 5018), The results showed that the varieties 5018 gave the highest mean for each of: plant height, leaf area 5526 and 5955 cm2, number of grains in the row, grain yield 6.07 and 9.19 t.

h-1 and the percentage of oil 4.24 and 3.99% For the two lugs respectively.

While the varieties Sarah gave the highest mean for number of rows in the ear and the percentage of protein 8.98 and 9.03% for the two lugs respectively.

The concentration 9 gm.

L-1 of the bio-stimulator gave The highest mean for each of the plant height, leaf area 5787 and 6415 cm2, number of rows per ear, number of grains per row, grain yield 6.02 and 9.29 t.

h-1 and percentage of oil 4.56 and 4.00% .

While the concentration 6 gm.

L-1 gave the highest mean of protein percentage 9.43 and 9.66% for two lugsrespectively.

The interaction between varieties 5018 and concentration 9 gm.

L-1 from bio-stimulator was significant in plant height, leaf area in the spring lug, grain yield and oil percentage.

While interaction between the varieties Sarah and the concentration 6 gm.

L-1 of the bio-stimulator was significant in the percentage of protein.
