Abstract

The presence of weeds in oil palm plantations can reduce fresh fruit bunch production by up to 80%. The applied weed control techniques affect subsequent weed composition. The purpose of this study was to assess the weed composition in oil palm plantations before and after mechanical and chemical weed control. The study was conducted on immature oil palm plantations (TBM) covering an area of approximately 1 ha. Weed vegetation analysis used the quadrat method with a sample plot size of 20 m2 and a sub-sample plot size of 1 m2. The number of sample plots was 9 with 18 sub-sample plots each in the dead stile and disc. The variables observed consisted of the number of weed species, the summed dominance ratio (SDR), and the level of weed distribution. The results showed a shift in the number of weed species before and after mechanical control in the dead stile and chemical control in the disc. There were 34 weed species in the dead stile before cutting and 30 weed species after cutting, while in the disc there were 15 weed species before herbicide application and 10 weed species after herbicide application. There was no shift in weed species with high SDR before and after cutting in the dead stile, while there was a shift in weed species before and after herbicide application in the disc. Weed species with high distribution levels in the dead stile were the same before and after cutting, while in the disc there was a shift in weed species before and after herbicide application. The weed vegetation community was relatively homogeneous before and after cutting and herbicide application.

Abstract

Edamame soybeans are a variety of soybeans that act as leaf vegetables that are rich in protein, minerals and vitamins. Edamame soybean cultivation is not yet popular, even though the need and demand is quite large. Eco-enzymes are inputs that play an important role as natural hormones and provide nutrients for plants. Eco-enzyme is an organic product that goes through an anaerobic fermentation process. A decrease in the yield of cultivated plants can be caused by competition with weeds. Several general weed control options have been developed, but appropriate weed control options are needed to ensure production and ecological sustainability. Research was carried out at the Teaching and Research Farm (1°370'129" S, 103°312'0.501"), Faculty of Agriculture, Jambi University. The research started in January and ended in March 2023 using a split plot design, as the main plot was the concentration of eco-enzymes and the weed control method was chosen as the sub-plot. The eco-enzyme treatments specified were 0 ml L-1(e1), 10 ml L-1 (e2), and 20 ml L-1 (e3). Weed control treatment consists of 2 (two) weed control methods, namely uprooted and cutting off. The parameters observed were morphological growth (plant height, number of root nodules, leaf chlorophyll content, and flowering time) and yield potential (number of pods, number of filled pods, and fresh weight of pods). The results showed that the differences in eco-enzyme concentration and applied weed control were not significantly different on morphological parameters (plant height, number of root nodules, and chlorophyll content of edamame soybean leaves 5 WAP) and yield potential parameters (number of pods, number of filled pods, and wet weight pods) edamame soybeans 65 DAP. Weed control through uprooting was able to increase the number of pods (4.39%), the number of filled pods (5.08%), and the wet weight of the pods (9.57%).Key words: eco-enzymes, edamame soybeans, weed control

Abstract

The mosaic disease caused by the Tobacco mosaic virus (TMV) potentially causes economic losses to chili, so it is necessary to be controlled. One of the ways to control mosaic disease is using chitosan. Chitosan can be obtained from animal shells. The research aims to study the potential of pensi clam shells and shrimp shells as a source of chitosan to control mosaic disease on chili. The research used a Completely Randomized Design with 5 treatments and 5 replications, each experimental unit consist of 3 plants. Treatments included healthy control (without TMV and without chitosan), diseased control (without chitosan), shrimp shell chitosan, pensi clam shell chitosan, and industrial chitosan. Chitosan can delaythe incubation period,the disease severity is reduced by up to 41.86%. Plant height and fruit weight on chitosan protected plants were significantly different from unprotected plants.The height on 28-day old plants with chitosan and without chitosan treatments was 103.39 cm and 95.98 cm respectively, and fruit weight at the first harvest was 57.10 g and 42.57 g respectively. The chitosan used in this research has the potential to reduce mosaic disease in chili. Chitosan can be combined with other control techniques in an integrated disease management. Key words: chili, chitosan, mosaic, Tobacco mosaic virus
