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…

Dinh Thi Nha Truc, M.Sc Division of Agriculture System  According the survey result on intercropping systems in coffee farms in the Central Highlands (Vietnam), there were four popular plants used to intercrop with coffee, such as durian (Durio Zibethinus), black pepper (Piper Nigrum L.), avocado (Persea Americana) and cashew (Anacardium occidentale L.). Because of the high intercropping density, coffee yield could only get less than 3 tons per hecta per…

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…
