Abstract

The present study aims to determine mangrove community structure in the mangrove tourism area of Pariaman City. This study has been conducted in October to December 2019 using the purposive sampling method and belt transect in three stations. A total of 21 mangrove species, 20 genera and 19 families was identified in this area. The tree level vegetation of mangroves was dominated by Sonneratia caseolaris (INP = 140,23%). The sapling level vegetation of mangroves was dominated by Dolichandrone spathacea (INP = 174,39%). The seedling and understorey level vegetation of mangroves was dominated by Acanthus ilicifolius (INP = 58%). The diversity of mangrove species in this study area is relatively low to middle (H? = 1,574 ? 2,212).

Abstract

The research of the effect of liquid organic fertilizer to the soybean growth on podzolik merah kuning soil has been held. The aim of the research is to know the effect of fluid organic fertilizer to he growth of soybean on podzolik merah kuning soil. This research is complete randomized design (RAL) about this research in 6 treatment and 4 repetation. Those are A = 0 ml/polibag, B = 60 ml/polibag, C = 120 ml/polibag, D = 180 ml/polibag, E = 260 ml/polibag, F = 300 ml/polibag. The data is analyzed by various investigation and continued test with DMRT. The result of research shows that it?s giving the positive effect of soil?s pH, the plant?s heigh, plants aged 7, 14, 21, 28, nd 35 days number of leaves, total wet weight?s plant, dried weight?s plant and number of nodule of these plants shows positive effect of the soybean?s growth. Key word : Soybean, liquid organic fertilizer, growth

Abstract

Long term period of using fertilizers is not beneficial for soil fertility due to decreasing soil organic matter content. Otherwise, the source of organic matter widely available as waste in the environment are not used optimally because the naturally decomposition quite long time. This problem can be overcome by utilizing various types of microbes, such as Trichoderma. This research conducted to determine the effect of organic fertilizer from the decomposition result of T. harzianum in enhancing growth of spinach plant. This study used a completely randomized design (CRD) with 6 treatments and 4 replications. The treatments were doses variation of decomposition of organic material; 0 g, 15 g, 30 g, 45 g, 60 g and 75 g. Data were analyzed with ANOVA and continued with Duncan New Multiple Range Test (DNMRT). The results showed that the application doses  of organic fertilizer from decomposition result influences height, number of leaves, leaf area, fresh weight and dry weight of spinach plants. Optimal dose for all growth is 45 grams/polybag.
