    EFFECT OF OSMO-REGULATORS ON GROWTH AND PRODUCTION OF PEPPER (CAPSICUM ANNUUM) UNDER SALINE CONDITION
    (2023-08-08) Lama Omar Ahmad Omar
    Abiotic stress factors are the most limiting for plant growth and production. Drought caused by water shortage is among the most impacting factor. Palestine has most of the limited renewable water resources. The agricultural sector depends on 51.5% of the total water consumption. Thus, is highly affected. Another major factor that limits productivity is high salinity mainly in arid and semi-arid region like Palestine, the deleterious impact of salinity is associated with water stress as well as nutritional imbalance. Therefore, this study was conducted to evaluate the use of DISPER as an osmoregulator on pepper growth under saline condition. Three levels of Osmo-Regulators (DISPER Osmotic GS) with (0, 0.5, and 1 g/plant) combined with three salt concentrations (0, 100, and 200 mM) of sodium chloride were used. The experiments were conducted in Tulkarm in northern Palestine. Pepper seedlings (Capsicum annuum) variety (Sharbaty) were grown in a greenhouse under natural light condition during the period from 14th October, 2021 to the 22nd January, 2022. One plant was grown in each pot (30 X30cm diameter and height). Filled with a soil mixture of 2:1 sand to peatmoss. The results revealed positive effect of adding DISPER Osmotic GS on plant growth and production of pepper plants under salinity stress. DISPER Osmotic salinity levels of saline water irrigated (100, and 200 mM) saline water, the researcher obtained the best result on chlorophyll content of pepper leaves by (53.775, 41.175 mg/m³) and flower parameters by (12.500, 6.500) respectively, compared to the controller. In addition, the results showed a higher fresh weight of root (14.090, 9.250 g) and the average length of fruits (12, 6 cm) for all measurements respectively. The of DISPER Osmotic GS at 0.5 and 1 gm increased the average area of leaves (179 cm2, 169.632). As a result, DISPER application can be used to alleviate the salinity harmful effects on plant growth and development of pepper plants under saline condition.
