The thesis deals with the yields of fruits, wood and honey of the sweet chestnut (Castanea sativa Mill.) in Bela krajina. The study area is located in the forest management unit Črnomelj. Data on chestnut fruit yields were obtained on twenty sample plots located on a 100 × 100 m grid. Some stand characteristics and properties of trees, under which fruits were inventoried, were assessed and measured. These data enabled analyses of their influence on fruit yield. Data on chestnut honey and timber yields were also obtained or calculated. On the sample plots, an average of 390 g of healthy chestnuts was obtained, which represents a yield of 487.5 kg/ha. The lowest yield was 254 g (318 kg/ha) and the highest 649 g (811 kg/ha). According to these results and the market price, the value of fruit yield ranged between 975 and 1706 €/ha/year. The value of the final felling timber yield would represent 6087 €/ha ± 4062 €/ha. The value of the wood volume increment was estimated at 37.2 - 148.7 €/ha/year at 1 - 4 % relative volume increment of chestnut growing stock. The value of the estimated yield of sweet chestnut honey was 300-540 €/ha/year. It was concluded that even in the worst case scenario the value of the sweet chestnut fruit yield would be almost 7 times higher than the income from the annual wood volume increment.
