Effects of spacing on rate of machine planting of Radiata pine

Abstract: A study is described which examined the effect of a wide range of initial density and rectangularity (the ratio of between row to within row spacing) on the rate of machine planting in Pinus radiata. A factorial design, employing three levels of density (749, 1683, 4305 trees per hectare) and three levels of rectangularity (1:1, 2:1, 4:1), was replicated three times in each of two well separated localities.It was found that the cost of planting falls as spacing at given density becomes more rectangular or as d… Show more

“…For example, in some situations the cost to establish a pine plantation might be cut in half by doubling the width between rows ( Table 3). This is, in part, because the costs of machine planting (and banded herbicide treatments) are directly related to the distance between rows [24]. In theory, the cost of hand-planting is also related to row spacing.…”
