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.

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

Hutan mangrove memiliki tipe dan jenis vegetasi yang berbeda sesuai dengan kondisi zonasi yang berhubungan dengan faktor fisika-kimia lingkungan, di antara faktor yang menyebabkan perbedaan vegetasi tersebut adalah jenis tanah dan pasang surut air laut. Penelitian ini bertujuan untuk mengetahui bagaimana sebaran tumbuhan mangrove berdasarkan tekstur tanah dan kondisi pasang surut yang terdapat di hutan mangrove Teluk Buo Bungus Padang. Penelitian ini dilakukan dengan pembuatan dua transek penelitian yang tegak lurus dari zona depan tumbuhan mangrove sampai ke zona transisi. Ukuran plot 10x10 meter dibuat tegak lurus mengikuti transek yang telah dibuat. Selanjutnya identifikasi jenis dilakukan pada semua tumbuhan yang ditemukan pada masing-masing plot baik dalam bentuk pohon, pohon muda (sapling), anakan pohon (seedling) dan tumbuhan penutup tanah. Untuk menentukan tinggi pasang dan surut air laut digunakan pancang yang telah dibalut dengan kertas krep sedangkan untuk analisis tekstur tanah dilakukan pengambilan sampel tanah di lakuan pada setiap plot masing-masing plot diambil tiga titik. Hasil penelitian diketahui bahwa sebaran tumbuhan terbanyak ditemukan pada tanah lempung berpasir yaitu delapan jenis, pada 21 plot penelitian. Sebaran tumbuhan terkecil terdapat pada tekstur tanah liat, hanya dua jenis yang mampu hidup pada tekstur tanah ini yaitu Rhizophora apiculata dan Sonneratia caseolaris

Abstract

Agroforestry or tree crops in West Sumatra is called parak, it mostly related to rural and farmers but at some developing areas the parak is still existed with a high potential changes in structure and floristic composition due to commercial orientation. To explore the possible changes of tree community in such developing areas, 11 of 20x20 meter plots were established across parak areas in peri-urban site in Lubuk Alung district, Padang Pariaman Regency, West Sumatra Indonesia, aimed to specifically investigate tree density, stand basal area, spesies distribution and other ecological atributes of the species. We found 24 tree species from 306 trees within 0.44 ha or about 695 tree per ha. Durio zibethinus was the biggest trees, found as a top canopy but few in number and spreaded quite widely across the areas, followed by some other species such as Cocos spp., Areca catecu, Garcinia spp., while small trees, high density but only spreaded at some places was represented by Theobroma cacao. Many species and the structure were typically agroforest that vary in canopy level and economic functions except some species which may be additionally planted to suit the needs of peri-urban community.
