Growth, productivity and nut quality of some Macadamia clones in Lai Chau provin
Keywords:
Quality of nut,, Macadamia, Lai Chau,, growthAbstract
The study has shown that there was a significant difference of diameter at ground level, height and crown diameter of mixed Macadamia forest at the age of five in Tam Duong District, Tan Uyen District and Lai Chau City, it was showed the best growth of Macadamia in Lai Chau City. There wasn’t a significant difference of growth and productivity of mixed six clones of Macadamia at the age of 6, the clones H2, OC, 816 had the average diameter at ground level of 10,1 cm, height of 4,6 m and crown diameter of 3 m at the surveyed time. The average productivity of the clones H2, OC, 816 was above 4 kg per tree. The fruit quality of 246, H2, 816 and 842 were the best with the balance of lipid, protein and cellulozo. The practice of Macadamia plantation in the province wasn’t concerned so much, the practice of fertilizing, watering and pruning is limited so fruit yield is low and unstable
