Abstract:
This study examined the grow ability of chilli pepper (Capsicum frutescens L.) seedlings in crude oil contaminated media with several different concentrations. This study used a completely randomized design (CRD) with 1 treatment of 5 crude oil concentrations (0, 1, 2, 3, and 4 ml/kg). Seeds were sown for 35 days in germination tubs containing a mixture of top soil with chicken manure (1: 1), then 25 individuals were moved into polybags containing 2 kg of top soil treated with (1, 2, 3 and 4 ml) crude oil. Vegetative parameters observed included root length, number of branches, number of leaves, leaf area, and number of fallen leaves. The observations for 16 weeks after planting on chilli pepper contaminated with crude oil on several parameters showed that root length, number of branches, number of leaves, and leaf area tended to decrease to a concentration of 3 ml/kg compared to controls, while the number of deciduous leaves concentrated at 4 ml/kg increased as a form of crop adaptation to stress
