The effect of pollution with heavy metals resulting from oil fields in some physical properties of fruits and the yield of date palm Phoenix dactylifera L. Hillawi cv. in Basrah Governorate.

Abstract

This study was conducted during the growing season 2018, with the aim to study the effect of pollution of heavy metals resulting from the combustion of fuel from oil wells in the Nahran bin Omar region in some physical properties of fruits and the yield of date palm trees Hillawi cultivar, in four sites with different dimensions are A (207 m) and B (2500 m), C (4000 m) and D (7,000 m) from the source of pollution, as well as a site for control (35,000 m). The results of the study showed that the fruits in the site closest to the source of pollution A recorded the highest mean in the weight, length and diameter of the fruit and reached (8.65 g and 3.54 cm and 1.39 cm) respectively, with a significant difference compared to other sites, while the lowest mean was found in the fruits of site B, which were (5.37 g and 2.76 cm and 1.19 cm) respectively. The results also showed that the highest tree production was at the control site of 42.82 kg with a significant difference compared to other sites, while the lowest was at site A and reached 14.17 kg. The results of the study showed that the proximity to the source of contamination with heavy elements negatively affects the total yield of date palm trees, but it was positive in influencing the physical characteristics of one fruit.
