Abstract: For assessment of organic matter input into the soil system information on the elements of primary production by overlying vegetation is quiet essential. Hence the primary objective in this study was to investigate the primary production and organic matter input into the study sites and to estimate the organic matter. Total below ground and above ground ratio was 4.68:1 and 4.94:1 in organic and conventional farming systems, respectively. Net annual increment in productivity was found to be more in organic than in conventional one. The contribution to net production by above ground biomass was more than below ground biomass. The efficiency of energy capture was maximum in rainy for both the systems
