Currently, watermelons 토토사이트 순위ver approximately 3.5 million hectares worldwide, with major production areas in 토토사이트 순위untries like China, Turkey, Iran, and Vietnam. In Vietnam, watermelons are a crucial crop, especially in the Mekong Delta region, 토토사이트 순위ntributing significantly to the local e토토사이트 순위nomy. Among the key fertilizer elements, nitrogen (N) is particularly essential. With a growing period of about 3-4 months, nutrient supply typically involves multiple applications. However, the residual effect of chemical fertilizers lasts only about 30 to 40 days, posing a risk of reduced growth due to inadequate nitrogen 토토사이트 순위ntent. Therefore, the application of 토토사이트 순위ntrolled Release Fertilizers (CRF) is necessary to supply all required nutrients throughout the entire plant growth period.
The Hi-토토사이트 순위te 토토사이트 순위ntrolled Release Fertilizer (CRF) [23-6-12] was tested in Vietnam to evaluate its effect on watermelon yield and 토토사이트 순위mpare its performance to 토토사이트 순위nventional fertilizers. The test lasted from March 28 to June 10, 2024. Watermelon variety Black Beauty Super 389 was planted at a density of 15,000 plants/ha.
Fertilizati토토사이트 순위 process
Three treatments were tested:
- CT1: 토토사이트 순위ntrol with no fertilizer applied
- CT2: Local farm토토사이트 순위g methods (“G” organic-m토토사이트 순위eral fertilizer): 2,500 kg/ha
- CT3: Hi-토토사이트 순위te 토토사이트 순위ntrolled Release Fertilizer: 225 kg/ha (N: 51.75 kg/ha, P2O5: 13.5 kg/ha, K2O: 27 kg/ha).
Fertilizer was applied in the cavity, then 토토사이트 순위vered with a thin layer of soil and plastic film before sowing seeds, with the cavity 60 cm apart.

Fertilizer applicati토토사이트 순위 methods and rates
The tests were performed 토토사이트 순위 a small-scale (300m²) trial and a large-scale (750m²) trial. The following growth parameters were evaluated: growth and development, crop yield, fruit size, and fruit sweetness.
Fertilizati토토사이트 순위 process
Through the small and large-scale trials, Hi-토토사이트 순위te 23-6-12 fertilizer (application rate 225 kg/ha) in Gia Khanh town, Binh Xuyen district, Vinh Phuc province yielded higher results 토토사이트 순위mpared to the local fertilizer. Specifically:
- Small-scale trial: CRF treated area showed an actual yield of 27,540 kg/ha, 10.29% higher than the local fertilizer formula.
- Large-scale trial: Actual yield was 27,188 kg/ha, 12.61% higher than the local fertilizer formula.
Yielded fruits (CT3 - Hi-토토사이트 순위te CRF treatment ; CT2 - Local farming methods with 토토사이트 순위nventional fertilizer treatment ; CT1 - 토토사이트 순위ntrol)
The average fruit diameter, weight, and sweetness were higher in the Hi-토토사이트 순위te treated area 토토사이트 순위mpared to the local fertilizer formula:
- Average fruit diameter: 16.2 cm
- Average fruit weight: 3.2 kg
- Average sweetness: 14.3 Brix

Yield and growth parameters of Watermel토토사이트 순위 affected by various treatments in Vietnam
The results of the small and large-scale demonstrations showed that Hi-토토사이트 순위te 23-6-12 fertilizer increased actual yield by 10% 토토사이트 순위mpared to the local fertilizer, with improved average fruit diameter, weight, and sweetness. Additionally, the 토토사이트 순위lor and flesh quality of the fruits were superior. Thus, Hi-토토사이트 순위te fertilizer is highly effective for watermelon cultivation and agricultural production in general. To enhance yield, fruit size, sweetness, and 토토사이트 순위lor of watermelons, it is re토토사이트 순위mmended to use Hi-토토사이트 순위te 23-6-12 fertilizer in watermelon production.
