Effect of cultivars, foliar application of ascorbic acid and amino acids on some physiological parameters of okra plant

Abstract EN

This study was conducted in the Orchards Development Project, Medicinal and Aromatic Plants, which belongs to the Holy Karbala Agriculture Directorate during the summer agricultural season 2020.

To study the response of three okra cultivars (Lahaloba, Batira and Hasinawi) to foliar treatment with ascorbic acid at a concentration of 100 mg.

L-1 with total amino acids at a concentration of 4 g.

L-1 The interaction of 100 mg.

L-1 ascorbic acid was studied.

and amino acids by 4 g.

L-1 In addition to the control treatment of and interaction between them in some indicators of growth and productivity of okra, the experiment was conducted as a factorial experiment according to the Randomized Complete Block Design (RCBD) and with a split plot system and with three replications.

The averages were compared according to the least significant difference test (L.

S.

D.

).

at the 0.05 probability level.

The results showed the Hasinawi cultivar excelled in increasing the plant height to 192.62 cm and the number of leaves to 162.58 leaves.

Plant-1 and the average dry weight of the shoot total to 13.67 g.

Plant-1, while the cultivar Batira was exceled in increasing the leaves content of total chlorophyll to 81.41 mg.

100 gm-1 fresh weight.

Spraying with ascorbic acid and total amino acids had a significant effect on vegetative growth indicators and gave the interaction between 100 mg.

L-1 and 4 g.

L-1 has the highest averages in these indicators compared to the control plants.
