A
3 x 3 factorial pot experiment was conducted to determine the effects of
different kinds of vermicompost on soil chemical properties of an acid soiland
to evaluatetheir influence on the growth and yield of tomato var. Diamante max.There
were nine treatment combinations from three types of amendments: (A1=Urea,
A2=Vermicompost 1, A3=Vermicompost 2) and three levels of
nitrogen: (B1 = 0 kg ha-1,B2 = 45 kg ha-1,
B3 = 90 kg ha-1) which were laid out in Randomized
Complete Block Design (RCBD) with three replications.The results of the study
showed that addition of two different kinds of vermicompost at a rate of 45 and
90 kg ha-1significantly (P ≤ 0.05) increased the chemical properties
acid soil such as soil organic matter, total N, extractable P, exchangeable K
and Mg compared to soils in untreated pots. However, the addition of two types
of vermicompostresulted in the decrease on soil pH. Growth and yield of tomato were
also significantly increased with application of vermicompostsat rates of 45
and 90 kg ha-1.In addition, application of 45 and 90 kg ha-1
urea also increased some of the chemical properties of acid soil andthe growth
and yield of tomato. The result of the
experiment revealed that addition of vermicomposts had positive effects on the
soil chemical properties and on the growth and yield of tomato.
