Morphological characters analyzed to identify the lizards were snout vent length and tail length. In three types of forests in Sungai Ambawang district, a total of 68 lizards of suborder Sauria were recorded, which consisted of 48 lizards from family Scincidae, 5 lizards of Gekkonidae, 3 lizards of Lacertidae, and 12 lizards of Agamidae. The result showed that the dominance index (C) in primary forest was 0,0865, secondary forest was 0,1046 and 0,1462 in Tembawang forest. Evenness index (E) of types of lizards was relatively low, with a value of 0,2248 in primary forest, 0,2644 in secondary forest and 0,2663 in Tembawang forest. The similarity index (SJ) in the three locations was around 0,5-1 where the three locations had the similarity in the species of lizards

Pertumbuhan Tanaman Kacang Tanah (Arachis hypogaea L.) pada Tanah Gambut yang Diaplikasikan dengan Bokashi Jerami dan Pupuk Petrhikaphos
Get PDFThe low fertility and high soil acidity make the peat soils require processing before being used as a medium for plant growth. Peat soil improvement efforts need to be done on an ongoing basis. This study aims to determine the effect and the optimal dose on the using of bokashi straw and petrhikaphos fertilizer on the peanut plant growth (Arachis hypogaea). This study used Factorial Completely Randomized Design (FCRD) with 2 factors namely petrhikaphos fertilizer (A) and bokashi straw (B). Each factor consists of 4 levels, they are: control, 5g; 15g and 25g for petrhikaphos fertilizer and control, 18,75g; 37,5g and 56,25g for bokashi straw fertilizer. The findings of the research showed that the using of bokashi fertilizer up to 56,25g dosage /plant has not been able to give a noticeable effect on the growth and yield of peanut crop production. Based on those four-dose treatments which were given, the dose of 25g /kg of seed showed the best result for the parameter root dry weight, number of pods, seeds, seed weight, number of nodules and the total number of effective root nodules. There were no interactions between bokashi and petrhikaphos fertilizer on to all observations A. hypogaea growth
