Green leaf extract of jatropha inhibited wheat seed germination.
Dry plant parts acted as manure and improved biomass and grain yield of wheat.
In agroforestry system with jatropha it could cause shading effects on intercrops.
During winter shading is minimized due to complete shedding of leaves in jatropha.
Wheat could be grown as an intercrop under wide spacing of jatropha plantation.
