Effect of complete and calcic fertilization on the initial growth of teak (Tectona Gradis Linn F.), Siuna, RACN, Nicaragua

Abstract

In Nicaragua, the demand for wood in quantity and quality has reduced forest cover, and therefore the establishment of forest plantations represents an important economic activity for the development of the northern Caribbean Coast. This research was done in teak plantations two years of establishment in the town of Siuna, North Autonomous Region Caribbean (RACCN) in the “El Waspado” Company Norteak HEMCONIC. The objective was to evaluate the effect of complete and calcium fertilization on stem variables during plant growth teak (Tectona grandis Linn F.). Block design was completely randomized (BCA) with three replicates and fertilization following arrangements: 40g 15-15-15 (full), 40 g 15-15-15 + 454 g of CaCO3 (full + lime) 40 g Tecaplex (Tecaplex), 40 g Tecaplex + 454 g of CaCO3 (Tecaplex + lime) and 454 g of CaCO3 (lime), as a control in two stages. Growth variables were considered in an analysis of variance (ANOVA) and LSD (∞ = 0.05). Plant height, diameter and volume statistically different treatments from 12 months after planting have been established, excelling applications complete formulation and lime.
