دور الزراعة الحافظة في تحسين الكفاءة الإنتاجية لمحصول القمح المزروع ضمن دورة زراعية مع الحمص تحت نظام الزراعة الجافة

Abstract EN

A field experiment was conducted in Jeleen Research Station, Dara’a governorate, Syria during the Two Consecutive growing seasons ( 2008/2009 – 2009/2010), in order to evaluate the performance of two wheat varieties (Acsad1105, and Acsad885) under conservation agriculture compared with conventional tillage system, in rotation with chickpea or without crop rotation.

The total number of grains per plant was significantly higher during the first growing season, under conservation agriculture system, with crop rotation, for the durum wheat variety (Acsad1105) (121.5 grains per plant).

The 1000-kernel weight was significantly higher during the second and first growing season, under conservation agriculture system, with crop rotation, in the durum wheat variety (Acsad1105) (41.40, 41.17 g respectively) No significant differences.

The average grain yield, biological yield, and the harvest index were significantly higher during the first growing season, under conservation agriculture system, with crop rotation, in the durum wheat variety (Acsad1105) (309.3, 822.2 Kg .

Donnem-1, 37.63% respectively).

These results assure the importance of implementing of conservation agriculture as an integrated cultural practices to increase the productivity of Wheat under dry farming systems
