Abstract

The study was conducted in a farmer’s orchard in the Al-Yuba/Al-Jazeera area in the north of Basrah Governorate during the 2022-2023 agricultural season. To determine the effect of proline acid and its role in reducing the negative effect of sodium chloride on the vegetative stage of alfalfa plant and its impact on the readiness of nitrogen when growing alfalfa around palm trees, using Four treatments (0, alfalfa, p1, p2). where 12 date palm trees, Al-Sayer variety, were selected as homogeneous as possible in terms of vegetative growth, height, size, and age. The results of the study showed the significant effect of the study treatments on most of studied traits of Al Sayer fruits. As the P2 treatment excelled in the weight of the fruit and seed as well as in the length, diameter, and size of the seed, as the following averages were recorded as 6.950 g, 6.233 g, 3.627 cm, 1.653 cm, and 5. 260 cm3, respectively. The P2 treatment also excelled in maturity percentage, shoot weight, and total yield, reaching 68.330%, 6.810 kg, and 40.847 kg, respectively. Adding proline to alfalfa crop around palm trees at a concentration of 30 ppm played a major role in increasing the yield.
