Author(s): Tu Trinh CongTu Trinh Cong
Coffee trees have high nutrient requirements, including boron (B). A field experiment with 2 factors of applying methods (leaf and root) and doses (0, 1, 2 and 3 kgs B ha-1 y-1) was implemented on basaltic soil in Central Highlands of Vietnam during 2015-2016. The results showed that supplying B remained appropriate B content in leaves, reduced in curly leaves and dropped fruits and increased in coffee productivity by 2.3-10.2% in comparison with control. The treatments of supplying 3 kg ha-1 got highest productivity, 3.87 t ha-1. In addition, the efficiency of B to coffee was quite clear, 76.7- 85.0 kg coffee kg B-1 in the cases of root applying and 95.0-123.3 kg in treatments of leaf spraying. Leaf spraying increased in yield of 0.11-0.23 t ha-1, corresponding the profit of 94.5-247.3 USD ha-1 in comparison with root applying. .. View More»
