Effects of motor oil pollution on soil and seedling growth of parkinsonia aculeata l.
Journal Title: Scientia Agriculturae - Year 2016, Vol 13, Issue 3
Abstract
The effect of various concentration of motor oil suspension (0, 1.25, 2.50, 3.75 and 5.0%) on soil and seedling growth performance of Parkinsonia aculeata L. was investigated. The oil pollution treatment significantly p<0.05 affected seed germination, shoot length, seedling height, number of leaves and average plant cover of P. aculeata. The significant (p<0.05) effects of oil polluted soil on root, leaves, stem and total plant dry weight of P. aculeata were also recorded. Increase in the concentration of oil polluted soil treatment exhibited higher percentage of decrease in different growth variables of P. aculeata than control. The soil analysis showed that motor oil treatment showed significant (p<0.05) increase in soil porosity (%) and concentration of soluble potassium, chloride, organic carbon, cation exchange capacity, extractable (K+) and Na+. While, a significant decrease in maximum water holding capacity of soil, bulk density, soluble potassium, exchangeable (K+) and Na+ ion concentration chlorides in the motor oil suspension treated soil as compared to control. The seedlings were grown in the same soil were analysed for the effects of motor oil pollution on the phenol and sugar contents. The amount of phenols and soluble sugar contents decreased in the seedlings of P. aculeate were significantly increased as compared to control with level of motor oil addition at 2.50%.
