Mucuna bracteata is a Legume Cover Crop (LCC) which has many advantages compared to other LCC. The generative propagation of M. bracteata is very difficult because of the seed coat is hard and thick, so that it has a long dormancy period and low germination. Germination without seed treatment, the germination ability only 12% to 18.33%. The efforts are made to break the seed dormancy by soaking the seeds in the sulfuric acid (H2SO4) to remove the lignin layer in the seed coat. The present study objective was to determine the appropriate concentration of H2SO4 for breaking dormancy of M. bracteata seeds. This research was conducted at the Laboratory of the 3rd Campus Andalas University, Dharmasraya, in April to June 2019 using a Completely Randomized Design (CRD) consisted of 3 treatments with 4 replications. The seed treatments were some concentrations of H2SO4 namely 3%, 4%, and 5%. The observed variables were T50 break dormancy period, germination ability, abnormal germination, dead seed, first count test, index value, and maximum growth potential. The observation data were analyzed by an F test at a 5% level, followed by the Duncan’s New Multiple Range Test (DNMRT) at a level of 5%. The results showed that soaking of M. bracteata seeds in H2SO4 with a concentration of 3% was the best treatment, a T50 value of 8.75 days after planting with a germination capacity of 78.50%.

Cameroon and Angola, accession palms oil, were two plants with different flower architectures such as bunch size, bunch length, number of spikelets and flowers, and volatile compounds produced. The difference in flower characteristics was thought to affect the presence of flower-visiting insects in the two palm oil accessions. The study aimed to determine the insects that visit Cameroon and Angola palm oil flower accessions. Insects that visit flowers were collected directly, using yellow pan traps, swing nets, and aspirators. Collected flower-visiting insects were identified as species. Diversity and evenness were calculated using the Shannon diversity index and the Simpsons’ evenness. The total number of flower-visiting insects collected was 2039 individuals. In the Angola accession, 150 individuals were found consisting of 5 orders, 10 families, and 14 species. Insects that visited Cameroon’s accession of palm oil flowers were 1889 individuals consisting of 8 orders, 16 families, and 22 species. Angola accessions’ diversity and evenness index were higher than Cameroon’s, namely 1.50; 1.14 and 1.14; 0.52. Flower-visiting insects that act as pollinators were Elaeidobius kamerunicus, Pyroderces Sp, and Thrips hawaiiensis.

Organic matter has a very important role in determining the level of soil fertility, especially in marginal soils such as Oxisol which is widespread in Indonesia. Organic matter that is commonly used requires large amounts and has the ability to react relatively slowly in the soil. Therefore, it is necessary to make efforts to obtain organic material that reacts quickly in the soil, such as humic material extracted from lignite. In this study, cocoa (Theobroma cacao) was used as an indicator plant. Cocoa is one of the plantation commodities that has a fairly important role in the national economy, especially as foreign exchange for the country and has a relatively stable price. This research was conducted in the form of a pot experiment using a 2 x 4 x 4 factorial design with 3 replications in a divided plot design, so that 32 treatments and 96 experimental units were obtained. From the research results obtained data that the addition of humic materials and compost up to a dose of 4% C-organic combined with artificial fertilizers can increase the availability of nutrients for cocoa seedlings in Oxisol. The best dose of each treatment was the addition of humic material at a dose of 4% C-organic combined with artificial fertilizer 50% of the recommendation and the addition of compost at a dose of 4% C-organic combined with artificial fertilizer 50% of the recommendation. The addition of organic matter can reduce the use of artificial fertilizers up to 50% of the recommendation. The addition of humic materials from unproductive coal can increase the availability of nutrients in Oxisol. Unproductive coal has the potential to increase Oxisol soil fertility.

This study was conducted to determine the composition of weed vegetation in Acacia mangium plants and to see differences in the composition of weed vegetation in several age classes of Acacia mangium plants in industrial plantations (HTI). This research was conducted in June to August 2018 in the industrial plantation of PT. Bukit Raya Mudisa (BRM) main road Km 13.7, Jorong Lubuk Mansagu, Kenagarian Koto Nan IV Di Bawah, Sub-district IX Koto, Regency Dharmasraya, Province of West Sumatra. The method used in this research is survey method by laying out the plot by purposive sampling in A. mangium gardens that are 2, 3 and 4 years old. At each age of the plant 2 observation plots were made measuring 40m × 40m in the plot. There were observational sub-plots measuring 1m ×1m in 10 plots of observation on a diagonal line with a total of 60 plots of observation. Based on the results of the analysis, there were 15 species belonging to 10 families. The number of weed species found in class 2, 3 and 4 respectively were 11, 9 and 11 species. The family of weeds that have the most species is the family Poaceae. Weeds are dominant under A. mangim plantations age 2, namely A. gangetica (38.26%), P. crinitum (14.81%) and I. cylindica (14.37%), almost the same as weeds under A.mangium plantations age 3 years namely A. gangetica (31.54%), A. compressus (20.49%), A.sessilis (19.50%), and P. crinitum (14.41%). The dominant age of 4 years weeds are A.gangetica (43.11%), A. sessilis (15.50%), and P. crinitum (15.36%). Weeds that dominate the A.mangium plantations are included in the group of broad-leaved weeds, so weed control is recommended in A. mangium plantations against broadleaf weeds.

One of the obstacles faced in oil palm cultivation, especially in the immature plant phase, is weeds, weeds can inhibit oil palm growth. So that weeds require special attention during cultivation, the presence of these weeds will become competitors for oil palm plants in fulfilling nutrients, light and water. This study aims to determine the composition of the types and vegetation structure of weeds in immature oil palm plants in large plantations so that the dose of herbicide with active ingredient Methyl Metsulfuron 20% is effective in controlling weeds in immature oil palm plantations in large plantations and studying the phytotoxicity of herbicides made from 20% active Methyl Metsulfuron in immature oil palm trees in large plantations. This study used a randomized block design (RBD), which consisted of 7 levels of treatment, 5 of which used the herbicide methyl metsulfuron 20% at a dose of 87.50 g / ha, 75.00 g / ha, 62.50 g / ha, 50.00 g / ha, 37.50 g / ha. ha and 2 including mechanical and control weeding which is repeated 4 times. Data analysis was performed with the F test, followed by the DMRT test at 5% level. The results showed that there were two species of weeds that dominated the research area, namely B. mutica and A. gangetica weeds with SDR values of 33.13% and 24.73%. The application of herbicides made from 20% methyl metsulfuron as active ingredients in controlling weeds in immature oil palm plantations is able to control 2 types of weeds, namely weeds including Melastoma malabathricum, Clidemia hirta with the best dose of 50.00 g / ha and 37.50 g / ha from the first 4 weeks up to 12 Weeks After Application (MSA).
