تأثير ملوحة مياه الري في نمو و حاصل صنفي الطماطم "سوبرماريموند" و "هتوف" المزروعين تحت الأنفاق الواطئة في المناطق الصحراوية جنوبي العراق

Abstract EN

Salinity poses a major threat to agricultural production in the studied area, therefore an experiment was conducted during winter growing season of 2010/2011 at Safwan sub district / Zubair in desert region South of Iraq in sandy loam soils to assess the effect of irrigation water salinity (8.3, 9.2 and 10.1 dS/m) on the growth and yield of two tomato (Lycopersicon esculentum L.) cultivars ("Super Marmande" and "Hattof") was studied.

The experiment explores the interaction between three levels of saline water and tomato cultivars grown under plastic tunnels at desert region.

Results indicated that growing tomatoes under 8.3 dS/m irrigation had higher values for plant length , number of leaves, lateral branches and inflorescence per plant , fruit weight and size , total soluble solid content as well as early and total yield per plant, whereas number of fruits per plant and percentage of the total acidity increased with increasing salinity to 10.1 dS/m.

Hattof cv.

gave the highest values for all studied parameter even under high salinity treatment.

However, "Super Marmande" cv.

had the highest number of inflorescence and number of fruit per plant.

It seems clear that "Hattof" cv.

is more salt tolerant than the "Super Marmande" cv.
