Khon Kaen University has made headlines with its groundbreaking research, which was showcased as one of the top 10 highlighted studies at the prestigious Farm Expo 2024. This event, the largest indoor agricultural exhibition in Thailand, was held under the theme “REVOLUTIONISING FARM BUSINESS” and featured over 14 innovation zones and 60 highlights, with more than 300 booths. The expo aimed to transform the agricultural industry, create new market opportunities, and drive sustainable growth for the Thai economy and its farmers. The event took place at the Bangkok International Trade & Exhibition Centre (BITEC) from October 3-6, 2024.
Among the standout innovations was the “Water Demand Estimation Program for Economic Fruit Trees,” developed by Assoc. Prof. Dr. Supat Isarangkool Na Ayutthaya from the Department of Horticulture, Faculty of Agriculture, Khon Kaen University. This research was selected by the National Research Council of Thailand (NRCT) for its potential to revolutionize water management in agriculture.
Dr. Supat expressed his excitement about the recognition, noting that the NRCT, a leader in post-harvest technology and fruit processing, selected this research from 18 institutions. The program aims to enhance Thai fruit exports by providing farmers with precise water management tools, thereby improving both the quantity and quality of their produce. This innovation not only reduces costs but also minimizes environmental impact, drawing significant interest from expo attendees.
The research addresses a critical issue for fruit farmers: determining the optimal amount of water for their crops. Insufficient water leads to low yields, while over-watering can wash away essential nutrients, increasing fertilizer costs. Funded by the NRCT, Dr. Supat’s program helps farmers deliver the exact water needed, ensuring robust yields and reducing energy costs. The program’s success has led to further funding for developing a similar tool for durian cultivation.
The study focused on four key fruit types: jujube, Thong Dee pomelo, Nam Dok Mai mango, and golden banana. Using advanced technology, the program calculates water needs based on weather conditions and tree characteristics. Farmers can easily input data into the program via a dedicated website, receiving precise daily water requirements for their crops.
For instance, the program suggests that a Thong Dee pomelo tree with a 65 cm trunk circumference, at 35 degrees Celsius and 40% humidity, requires 78 liters of water per day. This precise approach to irrigation promises to transform agricultural practices.
Looking ahead, Dr. Supat is collaborating with the Department of Agricultural Extension to further develop the program and train farmers nationwide. This initiative is set to empower farmers with cutting-edge technology, ensuring sustainable and profitable agricultural practices.
