The study presents a comparison of an effect of greenhouse gas emission load on the environment caused within the production of crops (rye, wheat, potato, carrot, cabbage, onion and tomato) under conventional and organic farming system in the Czech Republic. For evaluation, the simplified LCA analysis focused on evaluation of greenhouse gas emission load, expressed in carbon dioxide equivalents, was used. Outputs were converted into 1 kg of agricultural production. Within the evaluation of agricultural phase, total emissions from the cultivation of crops and emissions from particular parts of agricultural phase (agricultural engineering, fertilizers, pesticides, seeds and seedlings, field emission) were surveyed. The results show that except for onion growing, there is a reduction of emissions for all studied crops.
