تأثير الري بالمياه المالحة في إنتاجية محصول اليانسون Anisum Pimpenella L. و تقدير عتبته الملحية في ظروف حوض الفرات الأدنى سورية

Abstract EN

A field experiment was implemented to study the impact of saline irrigation water on the productivity of Anise and estimate its saline threshold.

A randomized-complete-block design consisting of (four treatments and three replications) four different levels of saline irrigation water was used over two seasons (2009/2010 and 2010/2011).

The soil analysis for each individual plot area was conducted before cultivating and water analysis for each water treatment was conducted.The productivity of grain and straw was estimated.

The study showed no significant decrease of the productivity of Anise compared to the blank with the use of irrigationwater which electrical conductivity value is 2.54 dS/m.

Anise is considered moderately sensitive to salinity, and its salinity threshold is about 2.54 dS/m and gets 1.31ton/ha offruit production which is about 80% of the production of the crop irrigated with fresh water.

Accordingly, it is recommended to disseminate the cultivation of the irrigation Anise under conditions of the lower Euphrates basin (Syria) and similar areas and using irrigation water with salinity amounting to 4.34 dS/m to obtain about 59% of the production of the crop irrigated with fresh water.
