تأثير نوعية مياه الري و الرش بالتوكوفيرول في نمو و حاصل الباميا Abelmoschus صنف محلي esculentus Moeneh

Abstract EN

The experiment was carried out in a private orchard at Shat-Al-Arab District, Basrah Governorate during the summer seasons of 2011 and 2012 in order to study the effect of irrigation water quality and spraying with Tocopherol on growth and yield okra plants tolerance to salinity resulted from irrigation by salinity water and its effect on the yield parameters .

Treatments included three sources of water i.e.

tab water, tab water + river water and river water and spraying plants with Tocopherol at four concentrations 0, 50 ,100 and150 mg.

L.-1).

Treatments of this experiment were distributed in Split Plot Design with three replicates, was Main Plots represents water sources, spraying with tocopherol represents Sub- Plots.

Means were compared according to L.S.D.

Test at significant level of 0.05.

Result could be summarized as follows : - Plants irrigated with tab water had a significantly higher vegetative growth parameters (plant height, leaf number.

Plant-1, number of lateral branches.

Plant-1, and.

plant-1), pod weight, pod number.

Plant-1, plant total yield (268.6 and 204.8 g) and hectare productivity (4.20 and 3.20 ton) for both seasons, flower number.

Plant-1 in the first season and fruits set percentage in the second season.

Plants sprayed with Tocopherol 150 mg.

L.-1 had a significant increase in plant height, number of lateral branches.

Plant-1, and leaf area.

Plant-1, flower number.

Plant-1, fruits set percentage, pod number.

plant-1, plant total yield (179.3 and 178.5 g) and hectare productivity (2.80 and 2.79 ton) for both seasons.

Leaf number in the second season and pod weight in the first season.

The interactions between the studied factors were significant in all stuided parameters for both seasons.
