Summary : The highest emission of 1.94 E-02 kg CO2-eq of GHG was obtained from the tomato production system while string beans production showed the least at 1.60 E-02 kg CO2-eq kg-1 of vegetable. Similarly, the highest and least acidifying compound emission from fuel combustion were also found in tomato and string beans production, values obtained were 9.99 E-04 gm SO2-eq and 7.93 E-04 gm SO2-eq kg-1 of veetable, respectively. 1.05 E-02 kg PO4-eq of eutrophication compound was recorded as the highest discharge obtained from the eggplant production system; the lowest value was from string beans production system at 7.8E-03 kg PO4-eq per kg of vegetable. Eggplant has the highest human toxicity potential in terms of 1 kg of vegetable both in air and soil, 4.61 E+ 00 g 1,4 DCB-eq and 1.7 E+03 g 1,4 DCB-eq. Tomato production shows the BCA value more than 1 while the other show less. Most impacts are directly due to farmer's production practices. The LCA approach on vegetable production provides informative feedback that can help decision-makers to select the product or process that result in the least impact to the environment and human societal. The study provided improvement of crop management practices to reduce environmental impacts as well as to increase the productivity and economic viability.
