Azadirachta excelsa

Now containing plants. The plantation was established following clear cutting of two rotations of rubber in March Influence of edaphic factors and tree nutritive status on the productivity of Pinus radiata D.

From the above relationships, it can be seen that the soil characteristics that best explain the differences in growth are slope for height and volume and K for dbh. The plantation in Terengganu is located about 10 km south of Sungai Tong town 5 o 21’N and o 53’E. Thinning of small trees was carried out in December A promising indigenous plantation species? InForestry Department of Peninsular Malaysia launched Forest Plantation Compensatory Project to coverha by the year with year rotation.

Azadirachta excelsa

The sample were oven-dried 70 o C for excela h, ground and digested with sulphuric acid and hydrogen peroxide wet digestion method. Coefficients of correlation between soil properties, foliar concentrations and growth parameters.

Nitrogen and P were determined by the similar colorimetric method used for soil. Abdul Latib Senin for the technical help. Concentrations of P, Mg and K which was higher for the latter element were at the maximum level as compared to study by Ong et al.

Crop response to lime in the southern United States. Two small branches on upper canopy of each tree were collected. Weeds were cleared by herbicide application each time before fertilization, leaving no ground cover for most of the time. Wise] General Information Sentang is a large deciduous tree, growing up to 50 metres tall. Low soil pH is often associated with high concentration of exchangeable Al. Growth is slow initially but subsequently increases significantly. An examination of the degtjareft method for determining soil organic matter and a proposed modification of the chromic acid titration method.

Kamis Awang Email address: The authors thank Mr. Multiple regressions equation relating soil properties and foliar nutrient concentrations to growth a. Operational schedules for application of fertilizers are presented in Table 1. The average annual temperature varies from Foliar sampling was carried out in August Foliar concentration of N and K were positively correlated with soil nutrient concentration.


The bark is pinkish grey or pinkish brown.

Potassium, Mg and Ca in the digest were determined by atomic absorption spectrophotometry. Pemerhatian awal pertumbuhan sentang Azadirachta excelsa berumur 3 tahun di Hutan Simpan Relai, Kelantan. Methods in applied soil microbiology and biochemistry.

Thus, the objective of this study was to examine how the growth of A. Ong Tai Hock, Mr.

Use of fertilizers in the area under the previous crop Adams, and the high rainfall could have resulted in the low pH. Spacing in seedbeds is 20 cm between rows and 5 cm within rows. Forest Research Institute Malaysia. The volume calculation wzadirachta was obtained from 42 harvested trees Ong, unpublished data.

Height and volume were influenced by slope, whilst dbh was influenced by N and K.
