In recent 10 years, mushroom cultivation area and number of cultivators have decreased, but mushroom production tends to increase. This shows that mushroom cultivation is being transformed from log and bed cultivation to bottle cultivation using automated facilities with high productivity per unit area. The bottle cultivation is possible to mechanized and automated, which can save manpower, less damage to pests, can be cultivated throughout the year, and is uniform in quality and advantageous for mass production. However, the investment in production facilities and farm materials is very large compared to the production of logs and bed cultivars, which can lead to large losses in the case of failure to grow. Therefore, it is necessary for the farmers who want to start the bottle cultivation to make careful management decisions by carefully examining the investment cost, the operating cost, and the expected income that are put into the bottle cultivation system. This study was conducted to analyze the management performance of bottle cultivation in mushroom farm and use it as farming decision making data. As a result of analysis of the management performance through farmers' survey, it was found that such as cost of spawn, substrate materials, other material, employment effort, and fuels & electricity power cost accounted for a large proportion of the cost of bottle cultivation.

A new rose variety, ‘Venus Berry’ was selected from the progenies of a cross between ‘Boy Friend’ and ‘GSR10315’ by rose breeding team of the Gyeonggi-Do Agricultural Research and Extension Services(GARES) in 2011. ‘Venus Berry’ was crossed in 2007 and seedlings were produced. After the test of specific characters from 2008 to 2011, it was finally selected and named. ‘Venus Berry’ was developed because of distinctive characters such as growth uniformity and high yielding potential. The petal of flower is so thick and has no scratch. A standard type with large sized flower, it has light pink(Red Purple Group 69C) color flower. ‘Venus Berry’ takes 45 days from pruning to blooming and cut flower productivity was 194.1 stems/m2 in a year. The length of cut flower was long with 65.5 cm. It has 10.2 cm in flower diameter and 43.6 in petal numbers per flower. Vase life of the this cultivar could be as long as 12 days.
