Present expriments were conducted to determine the possibility of cultivation of Coriolus versicolor selected among the higher fungi growing in Korea. Dried apple sawdust used in this study consisted of 31.5% C, 0.54% N, 2.41 % CaO, 0.05% $P_2O_5$, 0.48% MgO and 0.81% $K_2O$(pH 5.6). Coriolus versicolor mushrooms were cultivated on the sawdust media; apple sawdust; rice bran=80:20 in 850cc polypropylene bottles. The isolate of Coriolus versicolor used was YCV collected from an Apple farm in Youngchun district. It took 34 days to make fruitbody from spawning. The fruit bodies produced the total fresh weight 28 g in a bottles, and converted to 64% of fresh weight.

A bottom-up approach has been conducted to estimate greenhouse gas (GHG) emission and to analyze the marginal abatement cost for the Korean horticulture energy sector. With the systematically derived activity and energy balance data, the BAUs have been estimated, along with the marginal abatement cost over the period 2010 through 2030. The result from the marginal abatement cost analysis may provide general guidelines and procedures for the establishment of GHG abatement polices.

In order to evaluate the effect of various cultural methods developed during last 30 years on grain yield of wheat and barley and structure of plant stand for uptake of nutrient and water, solar energy use and com-petitive capacity with weed, 10 kinds of cultural practices were compared in the clayey upland soil. Row fertilization is more effective for uptake of N,P and K than rotary fertilization. Weed occurrence was deeply related with width of non-seeded area in the row and affected yield decrease. Winter injury was more serious in the cultural practices with thick plant community than in those with isolated individual plant. Root distribution was more remarkable in drill seeding or broadcasting than row seeding and had positively correlated with water consumption of barley.
