Watermelon is one of the most popular fruits during the hot summer months in many countries around the world, including Korea. These refreshing fruits are cultivated in regions with tropical to temperate climates, requiring temperatures above 25°C (77°F) to thrive. In Korea, watermelons are particularly popular, with an annual per capita consumption of about 10kg. This article will describe the farming methods of growing watermelon in Korea, with a focus on the use of Nousbo's 사설 토토사이트 technology and insights into key cultivation regions like Haman, Buyeo, Nonsan, and Jeollabuk-do Gochang.

Standard Product Sizes for 사설 토토사이트s (S~L Size)

The standard sizes for 사설 토토사이트s in Korea follow the specifications set by the National Agricultural Products Quality Management Service (NAQS). There is a preference for medium to large 사설 토토사이트s.

Characteristics of High-Quality 사설 토토사이트s

High-quality 사설 토토사이트s are distinguished by their color, freshness, ripeness, and the absence of major and minor defects.

1. Color: The rind should have a vibrant, glossy color unique to 사설 토토사이트s. 2. Freshness: The stem should be fresh and not wilted, and the rind should be firm. 3. Ripeness: The flesh should have a distinct color characteristic of the variety and be appropriately mature. 4. Major Defect Fruit / Minor Defect Fruit: There should be no major or minor defects. In Korea, 사설 토토사이트s command the highest prices from April to May. In regions like Gochang, 사설 토토사이트s are shipped year-round. The 사설 토토사이트 surveyed for this study was a large-scale operation with over 10 greenhouses.

Cultivation Schedule for 사설 토토사이트s in Korea by Growth Period

Watermelons can be grown throughout the year depending on the cultivation method, resulting in diverse growth schedules. In this case, farms using Nousbo's “Hi-Cote” Controlled Release 사설 토토사이트 (CRF) aimed for an early July harvest. Like most facilities utilizing cultivation under structure, where Electrical Conductivity (EC) levels often exceed 7, the use of Hi-Cote was notably different as the initial understock did not perish, deemed safe by the farm's representative.

Even at a glance, locations using Hi-Cote Controlled Release 사설 토토사이트 (on the left) display more intense leaf density and richer leaf colors compared to those using conventional 사설 토토사이트s (on the right). Conventional 사설 토토사이트s have high Electrical Conductivity (EC), often leading to plant death even after transplanting and fertilization, especially during flowering and post-fertilization periods. In contrast, Hi-Cote Controlled Release 사설 토토사이트 withstands high salinity effectively during early growth stages.

Characteristics and Advantages of Hi-Cote 사설 토토사이트

1. Characteristics of 사설 토토사이트 CRF

A. Improved Early Growth: Contains more than 20% nitrate nitrogen, promoting rapid early growth and ensuring safety from nutrient deficiencies. For watermelons, vigorous 사설 토토사이트 efficiency is crucial in the early growth stages to secure the number of stems and support development. Additionally, with the recent understock's strong nutrient absorption ability, it is beneficial for the 사설 토토사이트 to have a rapid initial effect and a somewhat slower release during the female flowering and fruit set periods.

B. Maximized 사설 토토사이트 Use Efficiency: Applying the 사설 토토사이트 directly to the crop's rhizosphere maximizes 사설 토토사이트 use efficiency. By targeting the understock's rhizosphere, the efficiency of 사설 토토사이트 utilization is significantly enhanced.

C. 100% Coated Controlled Release 사설 토토사이트: All components (nitrogen, phosphate, potassium) are coated using unique advanced coating technology. This ensures stability against 사설 토토사이트 damage and nutrient loss.

D. Designed to Meet Crop Nutrient Requirements: The 사설 토토사이트 is formulated with Linear and Sigmoid release technologies to match the crop's growth period and nutrient needs. This design promotes fruit thickening growth and maximizes the leaf area index (LAI) throughout the development of the watermelon.

2. Advantages of 사설 토토사이트 CRF

A.Reduced Fertilization Labor: By applying 사설 토토사이트 only once at planting, nutrients are supplied throughout the entire growth period, eliminating the need for additional fertilization. This reduces the frequency of injected fertilization and thereby decreases additional labor requirements.

B.Reduced 사설 토토사이트 Usage: 사설 토토사이트 is applied directly to the crop's root zone, minimizing application to areas like interrow and hill spacings where crops are not planted. This reduces overall 사설 토토사이트 usage, as plants absorb the Hi-Cote 사설 토토사이트 in the root zone and any 사설 토토사이트 accumulated in the interrow and hill spacings.

C.Maximized 사설 토토사이트 Utilization: Nutrients are released when needed by the crop, reducing losses due to volatilization and eluviation. Continuous 사설 토토사이트 efficiency prevents deficiencies during fruit maturation, promoting watermelon growth and quality.

D.Alleviation of Salinity in Controlled Environments: Reduced 사설 토토사이트 usage decreases salinity issues in greenhouse cultivation. Slow nutrient release allows for effective EC absorption, mitigating salinity problems.

E.Minimized Environmental Impact: Reduced 사설 토토사이트 usage significantly lowers greenhouse gas emissions and reduces water pollution from non-point sources, thereby improving water quality.

Recently, watermelon cultivation in Korea has expanded significantly, with over 80% being grown in controlled environments. The trend is to produce 2-3 fruits per plant. Under traditional cultivation methods, watermelons weighed around 8-10 kg. However, with the use of Nousbo's 사설 토토사이트, the weight has increased to 12-14 kg, and the brix (sweetness) has also improved.

A test watermelon was cut open, revealing high sweetness and a potential weight of over 13 kg, likely qualifying for the highest grade. The farm representative plans to use Hi-Cote on over 10 hectares in the future. Farmers have also tried other companies' controlled release 사설 토토사이트s but are satisfied with the cost-effectiveness of the Nousbo’s CRF.
