Fly ash application with a rate of 0, 50, 100, $150Mg\;ha^{-1}$ in clay loam paddy, which had properties of pH 5.3 and low contents of silicate and boron, gave a strongly positive effects on the growth and yields of malting barley showing better responses in bituminous coal fly ash(BCFA) than anthracite fly ash(AFA). Especially, soil chemical characteristics improved greatly by fly ash were pH, available phosphate, exchangeable calcium, available silicate, and boron. Shoot length and the number of tiller till defrosting season appeared the most positive responses by application of BCFA $50Mg\;ha^{-1}$ and AFA $100Mg\;ha^{-1}$. However, the number of spikelet per panicle at heading stage was proportionally increased to the rates of each fly ash. As a result, the grain yields of malting barley were increased to $13.8(4.221Mg\;ha^{-1}){\sim}37.7%(5.106Mg\;ha^{-1})$ by application of BCFA and to $1.1(3.75Mg\;ha^{-1})-20.6%(4.473Mg\;ha^{-1})$ by application of AFA. Protein contents in the grain was the highest in $150Mg\;ha^{-1}$ plot, showing 10.5 and 10.8% by BCFA and AFA application, which were suitable for malting. At harvesting, plants showed 49 and 58% of lodging indices by application of BCFA 100 and $150Mg\;ha^{-1}$, respectively, which were equivalent to two fold values of those by AFA.

In order to determine the optimum harvesting time based on grain filling and physico-chemical qualities for malting, three cultivars were harvested at every five days from 30th day after heading date at two experimental sites in the southern part of Korea. Starch accumulation and kernel weight increment were remarkable until 45th day after heading, but negligible after that. Content of ash, crude protein and polyphenolics and ${\alpha}-amylase$ activity decreased with maturation of grains and reached to the lowest value at 45th day after heading date. Germinative energy and capacity were good enough for malting from 40th day after heading date. The optimum harvesting time were estimated at 45th day after heading date in the increment of starch accumulation and kernel weight. At this time matured and immatured kernels were in the ratio 93 : 7. However, it is estimated that early harvesting time was at 40th day after heading date.

From November 5th to December 5th in 1984. this study was carried out to find the effects of the prechilling and predrying treatment on the germination rate, the plant rate, the plant height, and the seedling growth rate in some varieties of barley and malting barley. The result obtained were as follows: In germination rate, barley varieties were the highest at the prechilling treatments for five and eight days and malting barley varieties were the highest at the prechilling treatment for eight days. In predrying, the seven days' treatment revealed higher germination rate than other in all varieties except Sacheon-6, Sacheon-6 showed the highest rate at the five days treatment. The growth rate in all varieties was the greatest at the prechilling treatments for five and eight days. In predrying treatments, the growth rate in Oweolbori and Hyangmaek was more effective at the predrying for three days, in Sacheon-6 for five days, and in Albori for seven days, respectively. The highest plant height was revealed at the prechilling treatment for five days in barley varieties and for eight days in malting barley varieties.
