The area of Western Serbia has the highest average production raspberries and a long tradition is also recognizable for quality export raspberries. On family farms this hilly mountainous area, raspberry takes place in small areas with large labour participation. research aims to show on farm through economic analysis solve problem shortage by producing an 0.2 ha. Based real data from several such farms, most important parameters were calculated shown calculation production. gross margin...

Dairy farms generate large amounts of manure as their by-product. In tie-stall and free-stall housing systems for dairy cows, in barns with a lot or little bedding used, the solid produced is mixture dung, urine bedding. traditional cattle farming which mostly practiced on small family farms, generated solid. The amount available from an annual basis substantially dependent farm production capacity number class cattle. Manure also affected by system, management practices type This study...
