 en Growth response of Taro ( Colocasia esculenta check for this species in other resources L.) in soil polluted with Abura petroleum oil
Bamidele, J.F. & Esan, Sijuade

Abstract

Field experiment was conducted to evaluate the effect of crude petroleum oil on cocoyam ( Colocasia esculenta check for this species in other resources L.). Plants were grown in substrates exposed to 0, 1, 2 and 3 L/m2 of Abura crude petroleum oil. There was significant growth stimulation (p≤ 0.05) in terms of number of leaves, petiole length, leaf area, plant dry weight, and chlorophyll content in plants subjected to 1-2 L/m2 oil. The dry biomass as well as other plant growth attributes showed significant reductions in plants grown in soil polluted with 3 L/m2 oil. The highest applied oil dosage also adversely affected the leaf chlorophyll content. The experiment demonstrated that cocoyam is sensitive to crude petroleum oil pollution.
