Gypsum and lime effects on teak growth and soil chemical attributes in silvopastoral system.

A field experiment was conducted to determine the effects of limestone and gypsum application on the soil chemical properties and growth of teak in a silvopastoral system, in the Amazon biome, Brazil. The factors studied were liming; gypsum; liming + gypsum (3000 kg ha-1 each) and control (no amends). Growth and soil data were evaluated at the age of eigth years. Teak height growth followed a sigmoidal pattern. Teak height and yield were increased with the combined application of lime and gypsum. The basal area and yield were the smallest with gypsum application. The leaf nutrient content was not improved with the separate application of gypsum and lime. However, the combined application of lime and gypsum increased the macronutrient contents i.e. calcium, nitrogen, phosphrus and potasium. Liming increased the values of soil pH, the sum of base (SB), base saturation (V%), Cation Exchange Capacity (CEC), and organic matter (OM). The results obtained in the present study indicate that the combined application of gypsum and lime together improves the teak productivity in the silvopastoral system.
