'Nongjin-go' is a new breed strain of Lentinula edodes, saw-dust bag variety. It is a cross combination of dikaryon Lentinula edodes ASI 3305mut and monokaryon L5-16 of L. edodes ASI 3305(Sanjo701ho). We crossbred them by 2011 and verified productive capacity from 2012 to 2013 in Rural Development Administration. Optimum temperature of mycelial growth is $30^{\circ}C$ and it of fruit-body primodium formation is range from 15 to $23^{\circ}C$. Nongjigo is agricultured at mid-high temperature well. Fruiting body is platy-hemisphere, light brown and centralizing. And bast is formed around edge of pileus. Yield productions per period is regular than 'Sanjo701'. Plastic bag culture medium is 1.5 kilogram and culture periods are 90~100 days. As its browning of pileus in culture is a little slow, Light and ventilation is needed a lot in light-culturing. Humidity is controlled properly for its color in fruit-body growing. Tested culture medium is consisted of 80% Oak-Tree saw-dust and 20% rice-bran.

This study was carried out to investigate the suitability of various agricultural by-products as basal substrates for the mycelial growth and fruiting body formation of Hericium erinaceum. For this aim, oak sawdust, cotton waste, sugarcane bagasse, Job's tears, rice hull, Chinese cabbage, and coconut waste were used as sole or mixed substrate(s). Corn waste and rice bran were used as nutrient supplements. The growth and density of mycelium, yield of fruiting body, and biological efficiency were compared among tested substrates colonized by Hericium erinaceum. The best measurement of mycelial growth and density, yield of fruiting body, and biological efficiency in a laboratory test was found in a spawn substrate composed with oak sawdust 80% and rice bran 20%. The suitability of this spawn substrate composition for Hericium fruiting body production was testified through practical tests in plastic bottles (850 ml) in a mushroom farm which had bottle cultivation facility. However, test in a mushroom farm which had plastic bag cultivation facility, best production of Hericium fruiting body (520 g per one bag) was observed in a spawn substrate composed of cotton waste 40%, saw dust 40%, corn waste 10%, and rice bran 10%.
