Abstract

Dai Minh pomelo is grown a lot in Yen Binh district, Yen Bai province, and Doan Hung district, Phu Tho province. EMINA product is a mixture of many beneficial microorganisms: Lactobacillus spp, Trichoderma spp, Bacillus spp, Streptomyces spp, and Rhodobater sp. Experimental study on Kha Linh pomelo variety 25 years later planted in Dai Minh commune. EMINA product research materials, research formula spray concentration: 0% - 1% - 2% and 3%, repeat three times, each formula 15 plants. The study was conducted for two years. The experiment was conducted from November 2018 to December 2019 on 180 trees, building a demonstration model from December 2019 to December 2020 with a scale of 02 hectares. The results showed that spraying at a concentration of 3% gave the highest yield, quality, and the lowest rate of black spot disease on leaves and fruits. The yield was 178.68 kg/plant, and fruit and foliar diseases showed the least (20.3% and 8.4%), respectively. In a 3% EMINA spray demonstration model with a yield of 47,255 kg/ha, the total revenue was 589.570 million VND/ha, and the profit was 343.02 million VND/ha. At the same time, the control had total revenue of 533.876 million VND/ha and a profit of 290.926 million VND/ha.
