Assessment of teak production characteristics using 1 m spacing in a plantation in Nicaragua

Popis výsledku v původním jazyce

This investigation was carried out in a forestry plantation in Central America, near the city of Diriamba in Nicaragua, where 48.9 ha of a 76.5 ha afforested area has been repeatedly planted with teak since 2006 (2006: 7.90 ha; 2007: 13.63 ha; 2008: 11.93 ha; 2009: 12.87 ha; 2010: 21.70 ha). This plantation is unusual because of the unique 1x1 m spacing of the teak trees and the limiting ecological factors of this arid tropical zone. The aim of the 1x1 m spacing was to promote the growth of tall teak stems, inhibit branching to prevent the formation of a wide crown and begin production from the first thinning with teak poles, which are suitable for some types of construction. In 2011, experimental plots were established and the growth parameters (height and circumference) of teaks in the plantation were measured. Additional data were recorded, such as mortality, or twisted and snapped trees. A field methodology was designed and the growth results recorded were formatted into tables and charts. Based on the measurements made in the experimental plots marked out in the plantation, a statistical assessment of the growth parameters was conducted. Teak seedlings planted in the same years were compared according to provenance in terms of height, circumference, yields and mortality. Altogether, 10,955 trees in 143 experimental plots were measured. The stands were 1 to 5 years of age, the total calculated growing stock was 1,287.89 m(3), the mean wood mass per hectare was 17.89 m(3), with a mean stand height of 3.03 m and mean DBH of 2.74 cm. Snapped trees amounted to 5.64%, twisted trees to 5.66% and mean mortality was 21.48%.
