The Effect of the Inoculation with the Mycorrhizae and Spray with FeSO4 and Anti-Transpirant on some Growth Characters and Yield of Okra Abelmoschus esculentus L. Moench

الملخص EN

The present experiment was carried out at one field of the research station (B) belongs to Horticulture Department/College of Agriculture/ Baghdad University during the summer season of 2017 in order to study the effect of the inoculation with the mycorrhizae and spray with FeSO4 and Anti-Transpirant (Armurox) on some growth characters and yield of okra Abelmoschus esculentus L.

Moench.

The experiment was lay out as a factorial experiment (2x3x2) in randomized complete block design (RCBD) with three replications.

The total number of treatments was twelve.

The three factors of the experiment included; the inoculation with mycorrhizae (M) (0 and 10 g.

plant-1), spray with FeSO4 (F) (0, 0.5, and 1g.

L-1), and the Anti-Transpirant 'Armurox' (A) (0 and 5 ml.

L-1).

The results showed that the three factors and their interactions had significant effects on most of the growth characters measured.

The inoculation with the mycorrhizae was superior in giving higher values of plant height, number of branches and total number of leaves per plant; 139.97 cm, 15.00 branch.

plant-1 and 165.85 leaf.

plant-1, respectively.

The M1F0A0 combination treatment recorded the highest number of branches per plant (16.50) while the M1F2A1 treatment recorded the highest values of plant height (145.66 cm), total leaves number (170.33 leaf.

plant-1), leaf area (731.36 dcm-2.

plant-1), number of pods (19.20 pod.

plant-1), and plant yield (809.40 g.

plant-1).
