Analysis of collected data from 2011, in structure of used agricultural land in Serbia shows that dominated plough land and gardens and meadows and pastures, until in smaller percentage are orchards and vineyards. Almost the same relation is noticed in other republics of former Yugoslavia (meadow and pastures are the most prevalent view of using the agricultural land in Slovenia, Macedonia, B&H and Montenegro). Share of area under wheat notice smaller oscillation in all republics in the period 2008-2010, until yield per hectare is equalized for the same observed period. Share of area under corn in correlation with sown areas, for the period 2008-2012 is almost equalized for all republics. The average yield of corn per hectare records declining trend from 2008-2012, and it shows that by production Serbia is behind Slovenia and Croatia. Also, it was stated that world production of cereals grow in 2012 and in 2013, contributed by corn and wheat production in China, North America, European countries and former Soviet Union. Analysis of used land capacities is emphasized importance of land as a limited factor in production and base on that has given recommendation for alleviating problems in agriculture and food production. Conclusions are given based on calculation of percentages and their mutual comparisons for every country included in the research.
