The method of ‘path coefficients’ has been used for analyzing correlation coefficients between yield of Wheat and its other biometrical characters under four different tree species. This technique helps in establishing the relative importance of various biometrical characters of Wheat, viz. plant population, plant height, number of tillers per plant, grain weight per earhead, and number of effective tillers as determiners of Wheat yield under different Multipurpose Tree Species (MPTs) in agroforestry system. It is observed from the correlation components that number of tillers and number of effective tillers exerted a greatest influence both directly and indirectly upon the yield of Wheat crop under all the four tree species.
