“…Third, daily air temperature and relative humidity reflect other key environmental factors due to their high correlations. Ahn et al (2021) and Jo et al (2021) showed that the trend in air temperature was similar to that of soil temperature and photosynthetic active radiation, and the trend in relative humidity was related to vapor pressure deficit. Lastly, in our previous study, the correlation coefficients between daily air temperature and relative humidity and strawberry fruit yield were 0.82 and −0.93, respectively ( Sim et al, 2020 ).…”

Advanced information and communication technologies (ICTs) have made data collection more efficient for agricultural studies. Using publicly available database in South Korea, we estimated the relationship between the management of air temperature and relative humidity and the strawberry yield during two harvest seasons. Longitudinal data of multiple greenhouses were merged and processed, and mixed-effects models were applied to account both observed and unobserved factors across the greenhouses. The averages of air temperature and relative humidity inside each greenhouse do not take volatility of the time-varying variables into consideration, so we assessed the management of each greenhouse by the percent of time that air temperature between 15 °C and 20 °C (denoted as T%) and the percent of time that relative humidity between 0% and 50% (denoted by H%). The statistical models estimated that the strawberry yield decreases with respect to the number of days since harvest began and the rate of decrease is slower when T% and H% are higher. This study used large-scale multilocation data to provide the practical suggestion that air temperature and relative humidity should be maintained within the optimal ranges to mitigate the loss of strawberry yield especially at the later phase of a harvest season.

Advanced information and communication technologies have made data collection more efficient, and crop growth, yield, and environmental data of multiple farms can be used for various purposes. Using the publicly available database in South Korea, we investigated the correlation between the management of greenhouse environments and the pattern of strawberry yield during harvest seasons. Location-specific datasets were merged and processed, and mixed-effects models were applied to account for both observable greenhouse conditions and unobserved factors associated with farm locations. Instead of using averaged temperature and relative humidity inside greenhouses, we estimated the percent of time that air temperature has been between 15°C and 20°C, denoted by T%, and the percent of time that relative humidity has been between 0% and 50%, denoted by H%. The strawberry yield tends to reduce with respect to time during a harvest season, but the reduction rate is slower when the T% and H% are higher. This study provides empirical evidence for the practical significance of maintaining air temperature and relative humidity within an optimal range, and we conclude that growers can mitigate loss of production by the maintenance of air temperature and relatively humidity particularly during the later phase of a harvest season.

“…The prospects for this technology is high promising, given its demonstrated ability to double farmers' earnings outside the rainy season. The success in chili cultivation, yielding 6.75 t/ha and generating substantial income, serves as a compelling model for other crops and regions facing similar challenges (Alam et al, 2010;Burney et al, 2010;Jo et al, 2021;Portugal et al, 2020). The economic viability of the system, which indicated by its positive NPV, high IRR, favorable PI, and short PP, makes it an attractive option for farmers and investors alike.…”

Rainfed rice is a farming field whose watering or irrigation availability merits rainfall, so then the farming activity only occurs in the rainy season. Based on the cultivation calendar of rainfed rice each year, farming activities are consequently taken 2 times and even worst only once. This condition directly impacting to the sustainability of rainfed rice farmers. If they carry out farming then they have earnings, if not then they get nothing. The application of solar-powered automatic irrigation means to perform efficient watering systems to the field and also for the water conservation treatment in horticulture farming during the dry season of rainfed rice as an alternative solution so that farmers can increase their income by carrying out one or two times cultivation. The method used in this activity is the discussion group forums (FGD), training, constructing solar panel automatic irrigation, and chilli cultivation using automatic irrigation. Using solar-powered automatic irrigation can increase farmer income to 100% in the dry season. More than 90% of farmers replenish a strong will to implement automatic irrigation in farming whether independently or by farmer group. Through this community service, the horticulture cultivation activity increased to 90%
