Research on the suitable dose of controlled release fertilizer for Robusta coffee in mature stage on reddish brown basalt soil in Dak Lak(30/08/2020)

Nguyễn Thị Hồng Hạnh, Đinh Thị Nhã Trúc, Phan Việt Hà The Western Highland Agriculture and Forestry Science Institute In coffee intensive farming, most farmers use soluble chemical fertilizers. However, when facing unfavorable conditions, a large amount of fertilizer will be lost; leading to reduces cost-effectiveness and increases the risk of environmental pollution. Therefore, the experiment “Research on the suitable dose of controlled release fertilizer for Robusta coffee in mature…

Nguyen Xuan Hoa, Ph.D and Nguyen Thi Thien Trang, BA. Division of Agriculture System This study was carried out to evaluate the effectiveness of biopreparation against Fusarium oxysporum in coffee. The experiment was conducted on an 8-year-old coffee, arranged in a randomized complete block design (RCBD) with 4 formulas, 3 replications, 9 coffee trees per plot; between two plots, there is a row of coffee to separate. One liter of…

This study used methanol solvent to extract active ingredients from cinnamon bark. After geting cinnamon bark extract, added chitosan powderto create biological preparations to protect coffee roots from harmful nematodes. Experimental results showed that preparations and extracts have had no effect on stimulating growth plants of aerial parts. Treatment formula for concentration of 0.2% of preparations got the highest efficiency in anti-nematicidal activity compared to other treatments. The efficiency of…

Truong La, Ph.D Division of Research Management and International Cooperation      Using 18 Brahman crossbred bulls from 19 to 20 months for an experiment to examine their Average Daily Gain (ADG) while using diets of Total Mixed Ration (TMR). The bulls were allocated into 6 lots, each of 3 heads. Bulls were fed in 3 different rations by starch foods (maize meal, rice bran, cassava meal) with the same…

The role of Saccharomyces cerevisiae in coffee fermentation in order to improve the green coffee bean quality(12/08/2019)

      Tran Thi Tham Ha (M.Sc) Division of Post-havest Studies       Saccharomyces cerevisiae is a species of yeast that is commonly used in food industry such as winemaking, baking and brewing. The yeast is able to secrete pectinlyase and polygalacturonase enzymes, which help the degradation of coffee mucilage and pulp. Saccharomyces cerevisiae is essential for coffee fermentation as it can contribute to accelerating the rate of fermentation,…
