Abstract: A field experiment was conducted during kharif season (2017) to study the “Effect of crop geometry with different levels of phosphorous on growth & yield of green gram (Vigna radiata L.) under Jatropha based Agroforestry system.” at the research farm of College of Forestry, Sam Higgin bottom University of Agriculture, Technology and Sciences, Allahabad - 211007 (U.P.), Experiment laid out in randomized block design with three levels of Cropping geometry [30×10 cm, 30×15 cm and 30×20 cm] and three levels of Phosphorus [(20kg ha^-1), (40kg ha^-1) and (60kg ha^-1)]. The result shows that application of different levels combination of crop geometry with different levels of phosphorous fertilizers increased growth and yield of green gram. It was recorded from the application of phosphorous fertilizer in treatment T₉ [30x20 +60 kg P/ha^-1] increased Pre-harvest observation viz., Plant height, No. of trifoliate leaves per plant, No. of branches per plant, increased. It was also concluded from trail that the application of fertilizers in treatment T₉ [30x20 +60 kg P/ha^-1] was found in increasing post- harvest observations viz., No. of Pods per plant, Number of grains per pod, Test weight (g) and grain yield (q/ha), stover yield (q/ha),harvest index.
