Grapes are a specific crop with high economic efficiency in Ninh Thuan province. Two high-quality grape varieties NH01-48 and NH01-152 have a great prospect for growing in nethouse by using high technology to improve quality and economic efficiency. Study on growing 2 grape varieties was conducted in 3 different types of nethouses in Nha Ho. Monitoring and evaluation of growth, yield, and quality of grapes were carried out in 2 crop seasons from 2020 to 2021. The study results showed that 2 grape varieties grew better when planted in 2 types of nethouses with movable roof design, climate control system (nethouse No1) and Y-shaped nethouse in rows, with roof cover, netting around (nethouse No3) suitable for dry and hot climate conditions and high wind in Ninh Thuan compared to the traditional nethouse type. Growing grapes in improved nethouses has increased fruit setting (reducing the rate of flowers withering and falling off) due to high temperature, reducing the effect of rain during the rainy season. Two grape varieties NH01-48 and NH01-152 had yields of 32.9 - 35.6 tons and 18.6 - 20.6 tons/ha/2 crops/year, respectively
high quality grape berries (Brix và gt
