This study was conducted to examine the effects of coir, peatmoss, and red clay (20%) + peatmoss (80%) media on quality and drainage solution in hydroponics of Solanum lycopersicum 'Mascara'. The tomato seedlings were planted in media on 29 April, and supplied with Yamazaki's tomato solution of EC $2.0dS{\cdot}m^{-1}$ and pH 6.5. Tomato fruits were harvested from 13 June to 24 August. Drainage amount decresed when solar radiation and air temperature were high. However, drainage amount were not different among coir, peatmoss, and red clay + peatmoss media. The EC of drainage in red clay + peatmoss medium was higher than that in other media during the cultivation period. Also, soild state and available moisture content was more in red clay + peatmoss mediun than in coir or peatmoss media. The soluble solids of tomato fruits increased by 10~17% at $5.5^{\circ}Brix$ in red clay+peatmoss medium compared with $5.0{\sim}4.7^{\circ}Brix$ in coir or peatmoss media. Also, the acidity of fruits was the highest to 0.66% in red clay + peatmoss medium than the others. The total yield of fruits in red clay + peatmoss medium increased significantly by 9.1% at 8,428 kg than at 7,725 kg in peatmoss medium, and ratio of marketable yield was higher than the other media. Therefore, red clay (20%) + peat moss (80%) medium is recommend for growth and quality of fruits in hydroponics of Solanum lycopersicum 'Mascara'.

Growth and fruit characteristics of 'Duke' highbush blueberry by mixture of different organic matters in soil were investigated. The soil acidity was 4.2 to 4.8, sawdust treatment was the highest, and peat soil and peatmoss treatments were similar. The organic matter content of the soil was 2.5% for sawdust and 4.1% for soil with peatmoss and peat soil. The soil hardness of all treatment was found to be about 1 ~ 5 kgf cm^-2 which was suitable for growing crops. The number of suckers and main stems were high in the order of peat soil, peatmoss, sawdust treatment. In addition, the blueberry plants in the peatmoss and peat soil treatments had thicker and longer suckers and more shoots than those in the sawdust treatment. Among the characteristics of fruit, there was no statistical difference between the organic materials treatment in weight, diameter, length, and hardness of fruit. However, the total soluble solid and fruit yield were high in the order of peat soil, peatmoss, sawdust treatment. Therefore, as a result of comprehensively reviewing the characteristics of growth and fruits according to the soil environment, it was determined that peatmoss could be replaced with peat soil for stable production in domestic blueberry cultivation.

The main objective of this work was to identify and evaluate possible substrate alternatives or amendments to peat moss. This study involves the physical and chemical characterization and growth test of wood sawdust and wood fiber in order to evaluate their use as components of horticultural media. The carbohydrate content, C/N ratio, pH, phenolic compound, total porosity and water holding capacity were 58.9%, 425.1, 4.8, 181.8 ($mg{\cdot}g^{-1}$), 82.5% and 47.1% in wood sawdust and 41.1%, 240.8, 5.9, 29.8 ($mg{\cdot}g^{-1}$), 90.6% and 56.2% in wood fiber, respectively. Wood sawdust (K, $998.0mg{\cdot}100g^{-1}$ ; Ca, $1196.0mg{\cdot}100g^{-1}$; Mg, $105.6mg{\cdot}100g^{-1}$) and wood fiber (K, $1250.1mg{\cdot}100g^{-1}$; Ca, $1982.6mg{\cdot}100g^{-1}$; Mg, $173.1mg{\cdot}100g^{-1}$) showed adequate mineral elements properties compared to peat moss (K, $0.02mg{\cdot}100g^{-1}$; Ca, $0.57mg{\cdot}100g^{-1}$; Mg, $0.13mg{\cdot}100g^{-1}$) for their use as growing media. The mixtures of the horticultural media were prepared using different substrate as wood sawdust and wood fiber to grow Chinese cabbage (Brassica campestris L.) in a greenhouse. The seed germination, leaf area and stem height were 75%, $0.50cm^2$ and 2.8 cm in PS substrate (containing 30% peat moss, 10% perlite and 60% wood sawdust) and 95%, $0.65cm^2$ and 3.3 cm in PF substrate (containing 30% peat moss, 10% perlite and 60% wood fiber), respectively. The seed germination and stem height of the PF substrate (containing 30% peat moss, 10% perlite and 60% wood fiber) was higher than those in peat moss (control). Utilization of wood by-product can be considered as an alternative media component to substitute the widely using expensive peat moss.

Bark is a general medium for potted Cymbidium in Korea, but it is difficult to shake off or eliminate the medium from the roots before exporting the potted plants. This working process can injure the roots and then deteriorate plant marketability. This study was carried out to select the optimum medium easier to eliminate from the roots instead of bark and the optimum amount of applied fertilizer to improve the plant growth. Cymbidium young plants 'Honey Hot' and 'Desert Look' were planted in pots with bark, cocochip, and peatmoss. The plants were treated with 2, 4, and 6 g of slow release fertilizer. The plant growth characteristics were investigated in the first and second years during production period of three years. The medium characteristics and mineral nutrient content of the leaves were also examined in the second year. In the first year, the plant growth of 'Desert Look' was improved in all peatmoss treatments more than bark. 'Honey Hot' showed the highest plant growth values in the bark treatment. In the second year, the plant growth of the two cultivars was improved in peatmoss. Cocochip treatments showed the lower plant growth values than bark and peatmoss in the first and second year. There was no significant difference among fertilizer amounts in all the media. The higher CEC values of peatmoss medium resulted to higher capacity to hold more nutrients than bark, and the nutrient retention of the peatmoss improved the plant growth. The higher K and Ca contents in the leaves would contribute to improve the plant growth. Consequently, it would be possible to use peatmoss instead of bark for Cymbidium young plants, but there must be always attention to appropriately water the medium and manage the moisture.

This study was conducted to investigate the possibility of biochar as an alternative medium to peatmoss using for Aster spathulifolius. We cultivated A. spathulifolius in four potting media with different mixing rates (v/v) of peatmoss (P) and biochar (B) as follows: B0+P3, B1+P2, B2+P1, and B3+P0 with vermiculite 3 + perlite 3. Also, we analyzed the chemical properties of media and the plant growth characteristics. The results were as follows: In case of media's chemical condition, B0+P3 and B1+P2 treatments showed higher tendency (p < 0.05). Plant height on B0+P3 and B1+P2 treatments was much higher than that on other treatments (p < 0.05). Root length on B1+P2 treatment was higher than on B0+P3 treatment (p < 0.05). B0+P3 and B1+P2 treatments showed higher number of leaves and dry biomass than other treatments. Therefore, our results support that Biochar : Peatmoss : Vermiculite : Perlite (1/3 : 2/3 : 1 : 1, v/v) could be a more economical potting medium for A. spathulifolius than peatmoss : vermiculite : perlite (1 : 1 : 1, v/v).

In this study we investigated the suitability of horticultural main organic root substrate materials (peatmoss, coir) for the development proper root substrate for working with bulb onion transplanter. We investigated seedling sprout ratio, growth and characteristics (bulk density, root substrate cohesion) those are suitable for mechanical transplanting by mixing with inorganic materials(red clay etc.). Although both seedling growth and root substrate bulk density were similar in peatmoss and coir based root substrates, we found that peatmoss mixing had higher root substrate cohesion compared to coir mixing. We assume that higher cohesion properties of peatmoss based root substrate will give more weight of root part during mechanical transplanting of young onion seedlings in the field. Because of this, we suggest that peatmoss is the appropriate ingredient for developing root substrates for working with bulb onion transplanter.

Cucumbers(Cucumis sativus L. CV. SHARP 1) were cultivated by bag culture for 5 months to investigate the effect of substrates on growth, yield, and mineral contents. The substrates used in the experiment were vermiculite + perlite +peatmoss(1:1:1=V:V:V), perlite+peatmoss(1:1=V:V), perlite+carbonized chaff(7:3=V:V), rockwool, sawdust, and chaff+chaff powder under 10 mesh (7:3=V:V). The rate of moisture content was highest at chaff powder under 10 mesh as 42.5% and was lowest at perlite+carbonized chaff as 31%. Plant height, No. of leaves, fresh and dry weight were increased in vermiculite+perlite+peatmoss(1:1:1=V:V:V). Marketable fruits and yield also showed same aspect with growth. All kinds of mineral contents except K in cucumber plants were higher at vermiculite+perlite+peatmoss(1:1:1=V:V:V), but K content was higher at perlite+ carbonized chaff(7:3=V:V) than those other substrates.
