Abstract

A study was conducted to observe the effect of spacing on the height and diameter relationships of tree species planted as shelterbelts in hot arid areas under irrigated conditions. Generally, spacing of 3m × 3m was found to be suitable for getting good height for the trees at a given diameter. Among all the species and spacings studied, E. camaldulensis at 3m × 3m spacing is found to be most appropriate for raising shelterbelts in the study area to diffuse the upper wind flows.

Abstract

In this article volume tables of Neem based on data collected by felling 25 sample trees from different plantations in Gandhinagar Division of Gujarat State are presented. Different models were tried. Equations having the best fit on the basis of minimum Furnival Index, minimum standard error of estimate and maximum correlation coefficient have been selected for volume calculations.

Abstract

An experiment was conducted to assess the effect of solid content of urea formaldehyde (UF) adhesive on the compression parameters of finger jointed sections of Eucalyptus wood. Three concentrations designated as UF1, UF2 and UF3 had solid contents of 36.8 %, 44.9 % and 57.6 % respectively. All three concentrations showed good efficiency under compression parallel to grain when small sections were joined with finger jointing. The study illustrated that a UF concentrations at 36.8 % to 57.6% solid content range can perform equally well when eucalyptus sections are joined with the finger profile used in the study.
