Recently, the demand for smart farms is increasing due to the increase in the cultivation area such as horticulture, fruit trees and special crops. However, due to the irregular weather changes and the cultivation method of the crops due to the different cultivation environment, there are frequent occurrence of diseases and insect pests and infectious diseases due to system error or carelessness, and the cycle is also very short. In addition, the Smart Farm business has been built by combining various sensors (temperature, humidity, CO2, illumination) and LED lighting, but it is costly in terms of frequent errors, lack of power supply, And thus the management can not be efficiently managed. Therefore, this paper combines real time sensing technology based on IoT Platform and high performance control technology to control pests and equipment errors and monitor the growth status of crops in real time based on big data analysis and Artificial Intelligence System.

The objectives of the research were 1) to develop the low-cost and high efficient desalination system to treat brackish water having high salt contents for irrigation at greenhouses near coast, and 2) to monitor and assess the effects of the brackish water desalination system on soil environment and growth in squash greenhouse cultivation area. The monitoring site was one of the squash greenhouse cultivation farm at Choengam-ri, Jinsang-myun, Gwangyang-si, Jeonnam-Do Monitoring results for groundwater irrigation water quality, and salinity showed a remarkable difference between control and treatment group. The salinity of soil at treatment group was less than at control group. While, the system made possible to increase the squash quantity from 4.7 ea to 6.3 ea at each and the average weight of the harvested squash was increased from 277.2 g to 295.1 g. The applied brackish water desalination system may be appled to reclaim sea or brackish irrigated area as alternative water resources, although long-term monitoring is needed to get more representative results at different level of salinity.

In recent years, the bagging cultivation of summer squash (Cucurbita moschata) is applied for surface protection during harvest and extension of storage period. In this study, the effect of plastic bagging cultivation of summer squash on improvement of quality and extension of storage period was investigated. The yield and the length of fruit didn't have no difference between bagging and control treatment but the bagging treatment significantly made more regular size and light weight of fruits, and increased the number of fruits because of the limitation of their growth. The bagging treatment decreased weight loss and fruit softening during the their storage. Therefore it showed effective means for quality improvement and storage extension of summer squash.

This study was performed to analyze the improvement of soil physical property and soil biota characteristics through cultivation of green manure crops for a one-year period before creation of a tea plantation as follows. The study revealed that the contents of available phosphate tended to decrease after sod-culture by green manure cultivation and open-pollination, when compared to the level before cultivation. The ratio soil porosity increased by approximately 30% when Crotalaria juncea and Sorghum bicolar L. Moench were cultivated, while the soil bacteria and fungi also increased. In a research on microfauna using a pit fall trap, the population number of the microfauna was 174 of 27 species in the plot of open-pollinated sod-culture and no organic matter application, and 268 of 26 species in the plot of Sorghum bicolar L. Moench. Consequently, the culturing tool of Crotalaria juncea recorded the highest level of species diversity at 2.5, the evenness index at 3.7 and richness at 4.6, with the lowest level of a dominance index. The ecological quotient of microfauna was 0.76 in the plot of Sorghum bicolar L. Moench, and 0.63 in the plot of Crotalaria juncea.

This study was conducted to find out the effects of plant cultivation activities in the village gardening program hosted by Gyeonggi-do on the psychology and physiology of participants. This study conducted a survey on 20 villagers aged 57.70±9.23 on average and collected their saliva before Session 1 and after the final Session 10. The experiment was conducted by carrying out the village gardening program once a week for total 10 weeks. Psychological assessment was conducted by measuring the level of plant cultivation experience, four elements (repose, fascination, coherence, legibility) of the Perceived Restorativeness Scale (PRS) and stress levels, and also conducting the Wilcoxon paired signed ranks test. As the result of comparatively analyzing the saliva collected before and after the program, the total cortisol level, which is a stress hormone, decreased with statistical significance after the program (t=14.521, p<.001). The level of plant cultivation activities increased with statistical significance after the program, and the PRS increased with statistical significance in the three elements of repose, fascination and legibility excluding coherence. In addition, as the result of examining the change in the stress level of participants with the sum of all item scores, it was found that the stress level decreased with statistical significance (p<.05) from 17.65 points to 15.30 points after the program. Hence, plant cultivation activities in the village community have positive effects such as attention restoration or stress relief. In addition, the activities can also contribute to mental connection and healthcare of residents.

To create an environment for growing ginseng sprouts, we developed a solar module that partially transmits and disperses light. A G to G type light transmission and dispersion solar module was developed using glass with a mist pattern applied, and the light dispersion effect of the developed module was confirmed through illuminance measurement. The output of one module is approximately 260 W, and the configuration consists of 48 cells in series in 4 strings. The cultivation system where the developed module will be installed was developed in the form of a container, and three units of 2.6 kW (260 W x 10 EA). The inside of the cultivation system consists of a shading screen, air conditioner, ventilator, plastic pot, etc. to create an environment for cultivating sprout ginseng. As a result of actually planting sprout ginseng, it was confirmed through verification that the plants were grown without any problems.

This present study was conducted to develop the domestic cultivation kit using water celery(Oenanthe Stolonifera DC.) seed. As the result of germination rates in 3 type inbred lines, the IT 232354 had the highest initial germination rate and final germination rate, and was selected as the inbred line to be used in the cultivation kit. The development of the domestic cultivation kit was carried out using the IT 232354 seeds. It was possible to cultivate up to 3 times harvest using the same root in this cultivation kit, though the growth decreased rapidly in the $4^{th}$ cultivation. As a result of investigating the effects of the type of nutrient solution on growth of water celery, the overall growth was the lowest in the nutrient solution for Oenanthe Stolonifera DC.(N.S.D.). The shoot growth was similar to that of nutrient solution for leaves and stem vegetables (N.S.L.S.) and amino acid fermentation by-product liquid (A.F.B.L.), however in the root growth, the N.S.L.S. was more effective than A.F.B.L. When it was harvested 4 times consecutively after 1 time of planting, the last survival ratio of A.F.B.L. was 100% while their ratios were 96.4% and 49.8% each for N.S.L.S. and N.S.D. For the growth by cultivation kit type, the hole type cultivation kit increased slightly compared to the 3 hole type cultivation kit in the $1^{st}$ and $2^{nd}$ harvest, but there was no difference in the $3^{rd}$ and $4^{th}$ harvest. Total yield of one cultivation kits showed the 3 hole type cultivation kit is much higher than the 2 hole type cultivation kit. According to the results of this experiment, it is possible to harvest three times by planting one times if it was cultivated using N.S.L.S. and A.F.B.L. in the 3 hole type cultivation kit.

Although sawdust cultivation of shiitake (Lentinula edodes) is becoming more common, it is insufficiently competitive in spring and autumn, the best time to breed shiitake. Thus, it is urgently needed to develop a technique for all year round cultivation of shiitake using mushroom growing beds. In the present study, the temperature changes according to the location of shiitake cultivation facilities were investigated. We confirmed that a refrigerator, an air conditioner, triple membranes, shiitake cultivation beds, fog nozzles which were installed in the shiitake cultivation facilities play an important role in keeping the low temperature. Bag cultivation of shiitake was tested in temperature variation from $14^{\circ}C$ to $29^{\circ}C$ with a $3^{\circ}C$ interval to know its cultivating temperature range in hot summer season. In summary, the sawdust cultivation of shiitake is possible when the temperature difference between top and bottom is maintained below $1^{\circ}C$. And the temperature of the shiitake cultivation facilities should be maintained below $23^{\circ}C$ in the induction period for fruitbody formation.
