In this study we surveyed the preferences of consumer packaging for mini pot flower plants to improve the flower market application in Korea. The surveys were consisted of the consumers residing in Seoul metropolitan (221), Gyeonsang (70), Jeonla (29), Chungceong (19), Gangwon (7), other provinces (3). A total of 349 eligible respondents (male 173, female 176) were surveyed with a self-administered questionnaire asking on the general characteristics for residents, packaging material, packaging design, type of flower pot, degree of transparency, convenience, consumer's demand for packaging development, a significant point when purchasing the flower pot product. The collected date was analyzed using a chi-square (${\chi}^2$) statistical test in SPSS program. Most residents prefer for mini pot flower plants packed with packaging characteristics of plastic material (56.4%), packaging design of separated type (76.2%), angled type (62.5%), and transparency (48.6%). The other question results showed that major consumer's demand for mini pot flower plants is maintaining the freshness quality and stability structure for them. Transparency of packaging can also affect directly the preferences for purchasing the mini pot flower plants. The packaging structure with a proper shape design may protect the fresh mini pot flower plants from shock or any other damage during distribution. The results of this study help to provide consumer's demand for packaging development and to give the greatest advantages in terms of production and marketability of mini pot flower plants.

Plant growth-promoting effects of rhizobacterial inoculation obtained in pot experiments cannot always be dependably reproduced in fields. In this study, we investigated the effect of inoculation with Azospirillum brasilense and Methylobacterium oryzae, which have displayed growth promoting effects in several pot experiments, on growth and fruit yield of red pepper under field condition in a plastic-film house. Four rows spaced 90 cm apart were prepared after application of compost ($10Mg\;ha^{-1}$), and red pepper seedlings (Capsicum annum L., Nocgwang) were transplanted in each row with 40-cm space. Experimental treatments were consisted of A. brasilense CW903 inoculation, M. oryzae CBMB20 inoculation, and uninoculated control. Twelve plots, 10 plants per plot, were allotted to the three treatments with four replicates in a completely randomized design. At the time of transplanting, 50 mL of each inoculum ($1{\times}10^8cells\;mL^{-1}$) was introduced into root zone soil of each plant, and re-inoculated at 7 and 14 days after transplant. Plant growth and fruit yield were measured during the experiment. Both A. brasilense CW903 and M. oryzae CBMB20 could not promote growth of red pepper plants. All growth parameters measured were not significantly different among treatments. There were large variations in fruit yield recorded on plot basis, and no statistically significant differences were found among treatments. The failure to demonstrate the expected plant growth promoting effect of the inoculants is possibly due to various environmental factors, including weather and soil characteristics, reducing the possibility to express the potential of the inoculated bacterial strains.

This study was carried out to investigate the effects of T-P concentrations in irrigation water on the growth, yield, and grain quality of rice. It acquire fundamental knowledges to set up irrigation water quality standards. The pot experiment was conducted with 5 treatments using irrigation waters. It consisted of various total phosphorus concentrations(control, 1, 2, 5, 10mg/L) and replicated four times with randomized block design. The results of this study showed that as T-P concentrations in irrigation water increases, plant height tended to increase. Dry weight of rice plant at T-P 10mg/L was significantly higher than the control. However, T-P in irrigation water did not affect plant height, tiller number, plant dry weight, yield, and quality of rice.

This study was aimed to determine effects of soil organic amendment as plant growing media component on restoration of planting ground. The changes of soil physical and chemical properties and germination and growth of kentucky bluegrass (Poa pratensis L.) were investigated. For treatments, soil was excavated at depth of 0-50 cm (referred as $S_1$) and at depth of 50-100 cm (referred as $S_2$). Then the half amount of $S_1$ soil was mixed with the soil organic amendment (coir dust 40% (v/v), bottom ash 25%, leaf mold 25%, vermiculite 5%, carbonized rice hull 5%) at a rate of 6% (v/v) (referred as $S_1CC$) and also the half amount of $S_2$ soil was mixed with the soil organic amendment at a rate of 6% (v/v) (referred as $S_2CC$) on pot in a 16 cm diameter and 14 cm height. The experiment was replicated 3 times with 3 pots per replication in randomized block design, and 100 seeds were planted per pot. In results, there was no significant difference in soil pH among the treatments with a slight decrease in soil hydraulic conductivity. However, in the $S_1CC$ treatment, positive increases in soil chemical properties, including electrical conductivity, organic matter, phosphoric acid, total nitrogen, exchangeable cation, and cation exchange capacity. Also, the germination rate, plant height, and number of leaves were higher in the $S_1CC$ treatment than those in other treatments. These results suggest that the addition of organic amendment to the soil at depth of 0-50 cm might be proper for restoring planting ground.

The present agricultural water quality standards are set by a policy goal. This is intended for water quality management of public water resources, but not for the use of water resources. These standards were not determined by considering the influence of water quality on the safety of agricultural produce and the growth, yield and quality of agricultural crops. Thus, this study was carried out to investigate the influence of irrigation water quality on the growth, yield, and grain quality of rice and acquire fundamental knowledges to set up irrigation water quality standards. The pot experiment was conducted with 4 treatments using irrigation waters with various total nitrogen concentrations (control, 1, 5, 10, 20mg/L) and replicated four times with randomized block design. The results of this study showed that plant height, number of tiller, plant dry weight, the uptake of N, P, and K, and rice protein contents tended to increase as the T-N concentration in irrigation water was increased. In addition, grain yield at T-N 20 mg/L was significantly higher than in the control, but the percentage of head rice was slightly lower due to the increase of green kernel and white belly/core kernel.
