Abstract

Among the crops that can potentially be used to provide the raw material needed for liquid biofuel production Jatropha curcas L. is the one that generates most interest in many development projects. The aim of this study is to evaluate the production and development of 3-year-old J. curcas L. seedlings in 2012. The results showed that after three years of planting, subsoiling and provenance have no effect on growth variables and on the major part of foliar functional traits. However, the number of branches in bloom (p = 0.0041) and in fruiting (p = 0.0091) varied significantly under the effect of subsoiling. Branching is significantly higher in the prepared plot than in the control. As a conclusion, tillage has increased branching, while provenance has improved growth in height of J. curcas L. plants.
