This study was conducted to evaluate the influence of crown diameter on plant growth after planting and fruit yield. All nursery plants were classified into three classes: A, > 9 mm; B, 8~9 mm; C, < 8 mm. The A-class nursery plant plot showed better root and plant growth after planting compared to the B-class and C-class nursery plants. The A-class nursery plant plot was 10 days faster in first flowering time then those of the B-class and the C-class. Also, the A-class nursery plant plot was 2~3 days faster in the mean flowering time. The accumulative yield of the A-class nursery plant plot was 481 g per plant, that of the B-class was 445 g, and the C 422 g, which the nursery plant plot of A-class yielded more 8.1% and 13.9% respectively than B-class plot and C-class plot per plant. In early yield of to February; A-class nursery plant plot showed 23.3% higher yield than B-class nursery plant plot, and 39.1% higher the C-class nursery plant.

The effect of biological control on the severity of hot pepper wilt disease was evaluated in the vinyl house with plants cultivated in the nursery soil containing chitin and chitinolytic microorganisms. The chitinolytic microorganisms, Trichoderma harzianum and Chromobacterium sp. strain C-61, were well survived in the nursery soil containing chitin. The hot pepper damping-off was markedly suppressed in the nursery soil containing chitin and chitinolytic microorganisms. The survival of chitinolytic microorganisms and suppression of damping-off were superior as the amounts of chitin added to the nursery soil increased, but growth of hot pepper was inhibited in the 10％ (w/w) chitin treatment. When the plants cultivated in the nursery soil containing 1％ chitin and chitinolytic microorganisms were transplanted in the vinyl house, the vegetative growth increased and the wilt disease was reduced as comparison with those of control.

The experiment was carried out to investigate the optimum nursery periods on bolting responses and fresh leaf yield in Solidago virga-aurea. The result were as followings: growth characteristics as affected by nursery periods was promoted at the 60 and 70days without cultural years. Bolting responses by nursery periods of first year was respectively 14.5 and 13.5% in 40 and 50days, but the plant showing bolting reponse was not appeared at the 60 and 70 nursery periods. The highest fresh leaf yield was 60 nursery period as 2,750kg per 10a. The more bolting rate was increased, the more fresh leaf yield was decreased. As a rusult, the optimum nursery period to produce high fresh leaf yield of this crop plant was 60days.

This study was carried out to determine the effect of various period of nursery on the growth, yield and labor saving of work by truncation on floral axis of Alisma plantago in the southern coastal areas of Korea. The growth characteristics such as p]ant height, number of leaves were more increased at 20 days of nursery period plot them that of nursery periods. The dried-root yield was highest then but the floral axis was lowest at the 20 days of nursery period plot then that of other nursery periods. Therefore optimum period on nursery of Alisma plantago was 20days of nursery period in southern areas of Korea.

Earthworm cast was investigated in this study in order to domestically develop inexpensive and safe plug nursery soil. 20,30,40 and 50% of earthworm cast were added to the nursery soil as vegetable plant growth media, in which peatmoss and vermiculite constituted the rest of the soil. The effects of earthworm cast on the growth of pepper (Capsicum annuum L.) seedling were obtained as follows. 1. According to the growth stages, significant differences(p=0.001) were recorded in number of leaves, leaf area and biological dry matter yield per plant(shoor or root dry matter yield per plant). In view of mixing ratios in the nursery soil, number of leaves, leaf area and stem weight per plant showed differences significantly at 1% level and leaf weight, root weight and biological dry weight per plant at 5% level, respectively. 2. The nursery soil with earthworm cast showed increased number of leaves and leaf area per plant compared to the commercial nursery soil particularly in the later stage of this study than in the earlier stage 3. Through the total period of seedling growth, leaf weight, stem weight and root weight per plant in the nursery soil with earthworm cast were genrally higher than those in the control and this trend was apparant in the treatment of more than 40% of mixing ratio with earthworm cast. 4. Although leaf weight per plant was higher than stem weight per plant till the 3rd week, from the 4th week stem weight per plant was getting higher. In the later stage of seedling growth, the stem weight was higher in the earthworm cast mixed treatment than that in the control. 5. There was no significant difference on biological dry matter yield in the earlier stage of this study, however in the later stage, it was higher in the earthworm cast mixed treatment than that in the control.

To survey the incidence of plant-parasitic nematode in strawberry nursery, 117 soil samples were collected from main producing area of strawberry nursery plants in 2016. The incidences of two major problematic nematodes such as root-lesion nematodes (Pratylenchus spp.) and root-knot nematodes (Meloidogyne spp.) were 11% and 3%, respectively. Strawberry nurseries using upland soil either in fields or in plastic-houses showed were higher infection rates of Pratylenchus spp. or Meloidogyne spp. than others. On the other hand, a strawberry nursery using pots filled with bed soil in plastic-house was the lowest infection rate with 0%. Phylogenetic relationships and distance analysis were performed for identification of Pratylenchus spp. and Meloidogyne spp. detected from strawberry nurseries. As the results, they were identified as Pratylenchus penetrans, Pratylenchus vulnus and Meloidogyne hapla. Meanwhile, when nursery plants of strawberry infested with P. vulnus transplanted to pots filled with sterilized soil, P. vulnus was detected from soil in pots as 33% frequency. Thus, P. vulnus can be spread through nursery plants of strawberry infested with that. These studies suggested that Pratylenchus spp. and Meloidogyne spp. were ploblematic nematodes in major areas of strawberry nursery plants and P. vulnus could be spread through nursery plants of strawberry.

This experiment was conducted to determine the effect of nursery soils and seeding density on seedling growth characteristics in automatic facility for raising of rice seedlings. The seedling characteristics were evaluated for the 10-day and 15-day old seedlings grown in six different nursery soils including farm-made soils. Two levels of seeding amount, 250 g and 300 g/tray ($60{\times}30{\times}2.5$ cm), were applied to compare the seedling characteristics according to seeding density on different nursery soils. There were wide difference in soil components among the nursery soils tested. In acidity of nursery soils, 'Bunoog 2' was the highest, pH 5.1, and 'Samkyung' was the lowest, pH 8.6. The content of available phosphate was the highest value, 843 ppm, in 'Bunong 1' and the lowest (74 ppm) in farm-made soils. The total nitrogen content of 'Bunong 1, 2, 3' and 'Weonjo' soils was higher than there of 'Samkyung' and farm-made soils. There was no difference in plant height among three types of 'Bunong' soils (Bunong 1, 2, 3), but the seedling height grown in farm-made soils was shorter than there in other nursery soils. The plant heigh was slightly taller as the increase of seeding amount from 250 g to 300 g/tray, and the difference in plant height was larger in 15-day old seedlings as compared with 10-day old seedlings. Dry weight of seedlings grown for 15 days in three 'Bunong' soils was heavier than those in other nursery soils. Based on the growing characteristics of seedlings grown in different nursery soils, the heat result was obtained from a nursery soil, 'Bunoog 2', among six marketing nursery soils tested.

This experiment was carried out to investigate the effect of runner development based on production period and to investigate the yield in different cropping type to nursery plant age. In runner development experiment, heating + lighting + $GA_3$ + cluster removal treatment increased the number of runners by 13.1 times higher in spring season than control(heating only) in overwintering mother-plant. Treatment of 20ppm $GA_3$ was the most effective for runner production in autumn. In nursery plant age experiment, 60 days old nursery plants produced more flower cluster than 40 days old ones. This result indicated that the yield potential was so low that overwintering runners would be adaptable for spring or summer cultivation.
