STUDY ON THE GROWTH RESPONSE OF PHYSIC NUT TO VARIOUS SOIL TYPES.

A field work has been conducted to study the impact of soil over the growth and seed output of Jatropha (Physic nut) for a period of three years at Krishna district of Andhra Pradesh selecting different Jatropha plantations. Various parameters like mean height, mean girth, average number of branches per plant were observed along with the phenological output with a regular interval in the study sites to compare the growth of Jatropha in varied soil conditions.Results revealed that both the physical growth and fruit yield were recorded comparatively high in the black gravel soils among all the field stations. Details of the study were mentioned here in the full paper.
