تأثير الأسمدة الخضراء و التسميد العضوي في نمو و إنتاجية صنفين من الزيتون (الصوراني و القيسي)‎ تحت ظروف الزراعة المروية

Abstract EN

This research was carried out in Mohasaa region, Homs province during the growing seasons of 2008 and 2009 to determine the suitable green manure compared with an organic fertilizer and control to improve growth and productivity of two local olive cultivars (Sorani and Kaissy) under irrigated agricultural condittions.

This study included six treatments: planting a mixture of legumes viz.

Vetch (Vicia paleastina L.), Grass pea (Lathyrus sativus L.) and Alfalfa (Medicago sp.) with barely (Hordeum vulgare L.), in addition to add fermented animal manure, with the presence of control.

It was noticed that the average shoots growth was significantly the highest in Grass pea (Lathyrus sativus L.) treatment in Sorani, and the mixture of legumes and barely in Kaissy.

(13.7, 9.24 cm respectively).

The average of leaf surface area was significantly the highest under Medicago treatment in Sorani, and the treatmment of legumes and barely mixture in Kaissy (4.150, 4.694 cm2 respectively).

At the same time, it has been noticed that there was a significant increase in the canopy volume by 15% in Sorani in Grass pea (Lathyrus) treatment during the second growing season, while the increase rate was about 17.5% in Kaissy in the legumes and barely mixture treatment during the same season.

The productivity and fruit weight were significantly higher when the animal manure was added in Sorani and Kaissy (20.59, 37.33 Kg.tree-1 and 4.25, 6.10 g respectively) Finally, the pulp pit ratio was the highest in Medicago treatment, and the mixture of legumes and barely in Sorani and Kaissy (6.01, 6.47 respectively).
