| Tóm tắt: | In preventing and reversing soi degradation, the experiments were conducded at Duc Trong site - Lam Dong Province for three subsequent recent years in order to access the effect of five different phosphate source on coffee growth. In general, the results collected from the trials showed that at five studied phosphate applications (TSP, Apatite, Ferphos , Gafsa and BGC) gave high positive response in crop yeilds. Application of different phosphate fertilizers considerably improved coffee yield, increasing 5.37%from BGC treatment annd 29.97% from TSP treatment. Especially, TSP treatment produced a notable increase in crop yield of Catimor coffee (90.50%), followed by Apatite treatment (59.05%), then Gafsa (43,30%), and the lowest response was Ferphos and BGC (26.11 and 20.4%). In respect of Robusta coffee, the effect of P application was quite different. TSP and Apatite produced a lower increase (26.96 and 26.30%). The results from other treatments (Ferphos, Gafsa, BGC) were only a bit higher than control. |
