0. Executive Summary
Judgment axis | detail |
| Item Identity | The accepted species of watermelon is Citrullus lanatus (Thunb.) Matsum. & Nakai, and it belongs to the Cucurbitaceae–Citrullus genus. ( Plants of the World Online ) |
| Domestic agricultural data | The Rural Development Administration's watermelon farming schedule designates the scientific name as Citrullus lanatus Matsum. & Nakai and classifies it as the Cucurbitaceae family. ( Nongsaroo ) |
| Edible parts | The main edible part is the flesh of the mature fruit, and the peel, white endocarp, and seeds are managed separately by product regarding whether they are edible or processed. |
| Harvesting stage | It is divided into the stages of young fruit → early fruit set → enlargement → maturation progress → marketability → full ripeness → overripe. |
| Cultivation temperature | The official agricultural work schedule of the Rural Development Administration suggests optimal temperatures of 28–30℃ for germination, 15–20℃ for flowering, 25–30℃ for growth, and 3–10℃ for storage. ( Nongsaroo ) |
| rhizosphere and soil | The Rural Development Administration suggests deep sandy loam with a pH of 5.5 to 6.8 as the suitable growing site. ( Nongsaroo ) |
| Climate characteristics | The Rural Development Administration suggests that watermelon is a warm-loving crop that is relatively resistant to drought but susceptible to high humidity, requiring an accumulated temperature of 800–1,000°C from flowering to maturity. ( Nongsaroo ) |
| Risk of serialization | The Rural Development Administration describes watermelon as a crop unsuitable for continuous cropping and suggests crop rotation and grafting as key management techniques. ( Nongsaroo ) |
| grafting | Grafting is utilized to improve adaptability to vine splitting disease and adverse environments. ( Nongsaroo ) |
| Quality Core | Fruit weight, fruit shape, skin color, pattern, sugar content, flesh color, hardness, ripeness, hollowness, cracking, yellowing, overripeness, decay, and seed condition are managed as a core Quality Dataset. |
| Selection Key | Since it is difficult to fully assess internal sugar content and cavities in watermelons based solely on their appearance, AX offers high value for non-destructive sugar content sorting and image/sensor-based internal quality assessment. The Rural Development Administration has been developing non-destructive sugar content sorting technology for fruits and vegetables, including watermelons. ( Nongsaroo ) |
| Shipping specifications | Data from the Rural Development Administration indicates that watermelon sorting is generally based on weight and that non-destructive sugar content sorting equipment can be utilized. Actual grading by kg is managed according to specifications specific to APCs and Buyers. ( Nongsaroo ) |
| Domestic statistics | The KOSIS "Vegetable Production (Fruit Vegetables)" includes area and production volume items for all watermelons and open-field watermelons. The currently searchable tables cover the years 1980–2024, and the data was updated on October 30, 2025. ( KOSIS ) |
| Latest production figures | The finalized values for the national watermelon cultivation area and production volume for 2025 will not be entered arbitrarily in this registration, but will be updated after verifying the latest KOSIS original table. |
| Food safety | Since watermelon is a product managed as a cucurbit fruit and vegetable, the pesticide use per Lot–harvest date–latest MRL–test report is linked. |
| AX Core | Connect Grafted Seedling–Plant–Female Flower–Pollination–Fruit–Enlargement–Ripeness–Brix–Non-destructive Sorting–Pack Lot–Buyer RFQ. |
| Final goal | Connects RFQs and repurchases from farmers, seedling/grafting, greenhouses/open fields, APCs/non-destructive sorting, distribution/food service/hotels, and Fresh-cut/juice/HMR buyers. |

3. Production, Harvest & Post-harvest
The Rural Development Administration's watermelon farming schedule suggests optimal temperatures of 28–30°C for germination, 15–20°C for flowering, 25–30°C for growth, and 3–10°C for storage. It indicates that the optimal growing site is deep sandy loam with a pH of 5.5–6.8, explaining that while watermelons are relatively resistant to drought, they are susceptible to excessive moisture and that continuous cropping should be avoided. ( Nongsaroo )
The Rural Development Administration's separate crop information also suggests a cultivation temperature of 25–30℃ and explains initial watering control and moisture management before fruit set, following sufficient watering at the time of transplanting. ( Nongsaroo )
