    Abstract
    Jatropha curcas L., a multipurpose, drought resistant, perennial plant belonging to Euphorbiaceae family has gained lot of importance for the production of biodiesel. The properties of the crop and its oil have persuaded investors, policy makers and clean development mechanism (CDM) project developers to consider Jatropha as a substitute for fossil fuels to reduce greenhouse gas emissions. However, basic agronomic properties of Jatropha are not thoroughly understood and the environmental effects have not been investigated yet. Grey literature reports are very optimistic on simultaneous wasteland reclamation capability and oil yields. Studies were undertaken at Solar Energy Centre, Gurgaon, India to evaluate the plant performance under different agro-practices with special reference to irrigation scheduling, VAM and biofertilizers' applications, plant spacing, pruning trials for maximizing tree architecture and higher biomass. Parallel experiments were undertaken to understand the scope of J. curcas for intercropping practices in the under storey of dominating monoculture tree stands (Prosopis, Acacia and Neem).
