Watermelon Yield Evaluation of Hi-Cote 토토벳 사이트 in Vietnam

• Experiment design:Dr. Kwon Oh Yeon, Chief Research Officer at Nousbo, Ph.D.
• Organization of the performance:National Center For 토토벳 사이트 Testing, Hanoi, Vietnam
• Address:No. 65 Sa Doi Street, Phu Do Ward, Nam Tu Liem District, 토토벳 사이트noi
• Field location:Binh Xuyen Hi-tech Agriculture and Forestry Co., Ltd., Xuan Quang, Gia K토토벳 사이트nh town, Binh Xuyen district, Vinh Phuc province
• Demonstration crop variety:Watermelon Black Beauty Super 389
• Date of experiment:March 2024 – June 2024

Currently, watermelons cover approximately 3.5 million hectares worldwide, with major production areas in countries like China, Turkey, Iran, and Vietnam. In Vietnam, watermelons are a crucial crop, especially in the Mekong Delta region, contributing significantly to the local economy. Among the key 토토벳 사이트 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 토토벳 사이트s lasts only about 30 to 40 days, posing a risk of reduced growth due to inadequate nitrogen content. Therefore, the application of Controlled Release 토토벳 사이트s (CRF) is necessary to supply all required nutrients throughout the entire plant growth period.

The Hi-Cote Controlled Release 토토벳 사이트 (CRF) [23-6-12] was tested in Vietnam to evaluate its effect on watermelon yield and compare its performance to conventional 토토벳 사이트s. 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.

Fertilization process

Three treatments were tested:

• CT1: Control with no 토토벳 사이트 applied
• CT2: Local farming methods (“G” organic-mineral 토토벳 사이트): 2,500 kg/ha
• CT3: Hi-Cote Controlled Release 토토벳 사이트: 225 kg/ha (N: 51.75 kg/ha, P₂O₅: 13.5 kg/토토벳 사이트, K₂O: 27 kg/토토벳 사이트).

토토벳 사이트 was applied in the cavity, then covered with a thin layer of soil and plastic film before sowing seeds, with the cavity 60 cm apart.

토토벳 사이트 application methods and rates

The tests were performed on a small-scale (300m²) trial and a large-scale (750m²) trial. The following growth parameters were evaluated: growth and development, crop 토토벳 사이트, fruit size, and fruit sweetness.

Fertilization process

Through the small and large-scale trials, Hi-Cote 23-6-12 토토벳 사이트 (application rate 225 kg/ha) in Gia Khanh town, Binh Xuyen district, Vinh Phuc province yielded higher results compared to the local 토토벳 사이트. Specifically:

• Small-scale trial: CRF treated area showed an actual yield of 27,540 kg/ha, 10.29% higher than the local 토토벳 사이트 formula.
• Large-scale trial: Actual yield was 27,188 kg/ha, 12.61% higher than the local 토토벳 사이트 formula.

Yielded fruits (CT3 - Hi-Cote CRF treatment ; CT2 - Local farming methods with conventional 토토벳 사이트 treatment ; CT1 - Control)

The average fruit diameter, weight, and sweetness were higher in the Hi-Cote treated area compared to the local 토토벳 사이트 formula:

• Average fruit diameter: 16.2 cm
• Average fruit weight: 3.2 kg
• Average sweetness: 14.3 Brix

토토벳 사이트 and growth parameters of Watermelon affected by various treatments in Vietnam

The results of the small and large-scale demonstrations showed that Hi-Cote 23-6-12 토토벳 사이트 increased actual yield by 10% compared to the local 토토벳 사이트, with improved average fruit diameter, weight, and sweetness. Additionally, the color and flesh quality of the fruits were superior. Thus, Hi-Cote 토토벳 사이트 is highly effective for watermelon cultivation and agricultural production in general. To enhance yield, fruit size, sweetness, and color of watermelons, it is recommended to use Hi-Cote 23-6-12 토토벳 사이트 in watermelon production.
