Quality characteristics of dasik were studied with varied the levels of rice grain particle size and green tea powder and compared them with commercially sold dasik. Among the samples with the same number of grinding times, the sample groups with the higher amount of green tea showed significantly the less mosture content(p<0.05). Hardness was higher in the samples containing higher amount of green tea among the ones with the same grain size (p<0.05). The M13G0.5 was evaluated to have the highest savory aroma with significance (p<0.05), and C1 to have the highest sweetness by sensory analysis. The developed dasik samples with lower rice grain particle size had significantly lower adhesiveness, chewiness, gumminess, and cohesiveness compared to those of commercial sample groups. In sensory tests, the compared groups showed significantly the higher savory aroma and flavor and very lower hardness when compared to those of commercial sample groups. With the results above, dasik with with varied the levels of rice grain particle size and green tea powder were developed with improved qualities compared to those of commercially sold dasik.

Rice has important role as a primary food resource in especially the Asia, Korea, China, India, Indonesia and Japan. After development and increasingly using artificial chemical fertilizer, rice is getting high quality and quantity to satisfy ever-increasing people. On the other hand, the earth environment is more polluted each day. Nowadays consumers are looking for the organic crops or foods that were grown with eco-friendly method and in pure farmland. With the immergence of this trend, it is time to development environmentally-friendly agriculture. One of the methods is growing green manure crops in winter or spring on the fields. For this reasons, growing rye and Italian ryegrass are useful to use green manure to enhance rice production without chemical fertilizers and make the property of the soil eco-friendly. To know how improve the quality and quantity of rice with green manures, rye and Italian ryegrass, first the characteristics of green manure corps were measured. Dry matter yields of the rye and Italian ryegrass were 2.21 and $1.81t\;Ha^{-1}$. And the percentages of the dry matter were 28 and 32%. And, analyzed mineral components in rye and Italian ryegrass were nitrogen, organic matter, $P_2O_5$, CaO, $C_2O$ and MgO. Specially, the percentages of the organic matter and the CaO between rye and Italian ryegrass have difference appreciably. the height of the rice on the Italian ryegrass-fertilized field was the highest among the variant fields. The height of the rice on the non-fertilized field was the lowest. Yield of the Italian ryegrass-, rye- and non-fertilized rice are 805.2, 639.9 and $415.3kg\;10a^{-1}$. At the result, Italian ryegrass is the most effective green manure among the 3 treated-fertilized.

This study was conducted to evaluate the nutritional value of locally produced organic agricultural by-products to substitute imported organic feeds for organic ruminant farming. Imported organic feeds (corn grain, soybean meal, soybean seed, oat grain, barley grain, wheat grain, buckwheat, sunflower seed meal) and byproducts (rice bran, grape seed meal, rice straw, soybean hull, soybean curd, rice hull, green kernel rice, and crushed rice grain) were analyzed for chemical composition and NDF, ADF, mineral, and amino acid contents and anti-nutritional factors. Dry matter, NDF and ADF contents in organic feeds were higher than those in conventional feeds. Especially, the 9.65% fat content of organic soybean meal was 6 times higher than the 1.95% fat content of conventional soybean meal. Fat contents of rice bran, grape seed meal, green kernel rice, and crushed rice grain were 25.66, 6.09, 3.57 and 1.59%, respectively. Protein contents of soybean hull and soybean curd were 14.68 and 19.87%, respectively, which are highest among organic by-products. Levels of aflatoxin in all feeds were below the safety level. Therefore, organic rice bran, green kernel rice and crushed rice as energy source, and soybean hull and soybean curd as protein source could partial replace imported feeds for organic ruminant farming.

The ${\gamma}$-oryzanol, ferulic acid esters, which are well-known for their function on cholesterol lowering and prevention of inflammation, diabetes and cancer, are found in the seeds of cereal crops such as rice, corn, wheat and rye. Among them, rice has been reported to contain the highest ferulic acid esters. Since rice cultivation with green manure as a N source is an environmental friendly agricultural practice, it is necessary to identify and quantify as well as evaluate the variations in these compounds in rice samples as affected by different green manure conditions. A total of ten components of ${\gamma}$-oryzanol were isolated and cycloartenyl ferulate, 24-methylenecycloartanyl ferulate, campesteryl ferulate and sitosteryl ferulate were identified as the major components in Korean rice cultivars, 'Unkwang' and 'Hopum'. Comparing the ${\gamma}$-oryzanol contents of these varieties, 'Unkwang' showed clearly similar pattern with conventional type. With the PLS-DA (partial least squares of discriminant analysis) using SIMCA 11.0 ver., the specific pattern and cluster of ${\gamma}$-oryzanol scores with green manure conditions were confirmed, and thus distinguishing green manure effects were possible.
