VEGETATIVE PARAMETERS AND CHLOROPHYLL CONTENTS OF OKRA (Abelmeschus esculentus L.) AND MELON......

In a crude oil polluted soil amended with cow dung and hydrogen peroxide, the vegetative parameters and chlorophyll concentrations of Okra (Abelmeschus esculentus L.) and Melon (Citrulus colocynthis L.) were examined. A 5kg soil sample was polluted with 200 ml of crude oil (4 percent v/w) and a control sample (no pollution). T1 (polluted soil + 1.2 kg cow dung), T2 (polluted soil + 1000 ml H2O2), T3 (polluted soil + 0.6 kg cow dung +500 ml H2O2), T4 (polluted soil without amendment), and T5 (Unpolluted soil without amendment) were employed in a completely randomised design. Each therapy was divided into two groups (A and B). After one month of post-remediation, okra and melon were planted in each pair of A and B and monitored for eight weeks. The chlorophyll content and vegetative parameters (germination %, plant height, leaf numbers, leaf area, fresh weight, and dry weight) were investigated. The addition of the amendments greatly increased the vegetative metrics and chlorophyll content of the plants, according to the findings. T1 > T3 >T5 > T2 >T4 was the sequence of vegetative improvement for the two crops. T2 > T1 > T5 > T3 > T4 was the chlorophyll content. Cow dung and H2O2 have been shown to be excellent remediation materials in crude oil polluted soil for improving okra and melon performance, and cow dung alone is the best treatment option.
