Abstract EN

The experiment aimed to study the effect of different concentrations (10 and 20) % of Nerium oleander L.

leaves extract and proline (20 and 30) ppm on growth and yield of Cicer aeitium L.

The field experiment was conducted during the growth season of 2012-2013.

The results showed that the best concentration of N.

oleander extract leaves was 10 % that showed significant increasing in plant height, branches and leaves number and dry weight during first and second periods measurement as well as the chlorophyll containing in leaves, crop growth ratio (CGR), number of pods, weight of 100 seeds, percentage of seed carbohydrates.

The results revealed that two concentrations of proline (20 and 30) ppm showed a significant increase in the chlorophyll contained in leaves, number of pods comparing with control plant, but the same concentrations led to significant decrease in dry weight and CGR.
