Abstract

Soybean is one of the most popular food crops for the community, but the needs for soybeans have not been fulfilled by soybean production. To meet the needs of soybeans, it is necessary to intensify agricultural land in Ultisol. This study aims to obtain the optimum concentration of humic acid and dosage of the Arbuscular Mycorrhizal Fungi (AMF) to increase soybean plants' production in Ultisols. This research was conducted from January to April 2020 in Beringin Raya Village, Muara Bangkahulu District, Bengkulu City, at an altitude of 10 m above sea level. The research design used a Randomized Complete Block Design (RCBD) two factors with three replications, arranged factorially in experimental units. The first factor is the concentration of humic acid, consisting of 4 levels: 0, 15, 30, and 45 mL L-1 . The second factor is the dose of AMF, consisted of 3 levels, namely: 0, 2.5, and 5 g plant-1. The results showed that the maximum soybean growth and yield in Ultisols were obtained from the humic acid concentration at 45 mL L-1 at the dose of AMF at 2.5 g plant-1 . The resulting production potential is 1.99 tons ha-1 . The administration of humic acid or AMF independently at this research stage had not yet given a maximum response to the growth and yield of soybean in Ultisol.

Abstract

Soybean (Glycine max (L.) Merill) is the third most important food crop after rice and corn which contains protein and other nutrients essential for the body. Ultisol soil is a less fertile soil that has many limitations on its physical, chemical, and biological properties. Efforts that can be made include the use of liquid organic fertilizer (LOF) and arbuscular mycorrhizal fungi (AMF). This research was conducted from February to May 2020, in Beringin Raya, Muara Bangka Hulu District, Bengkulu City with an altitude of + 10 m above sea level. The purpose of this study was to explain the growth and yield of soybeans due to the application of liquid organic fertilizers and arbuscular mycorrhizal fungi in Ultisols. The research design used was a randomized complete block design (RCBD) with 2 factors with three replications. The first factor is the LOF dose which consists of four levels, namely: 0, 20, 40, and 60 mL L-1. The second factor is the AMF dose with three levels, namely; 0, 5, and 10 g plant-1. The results showed that there was no interaction between LOF and AMF. Giving a LOF concentration of 60 mL L-1 gave the highest yield on the growth and yield of soybeans, as well as the optimum concentration for seed/plant weight, which was 28.114 mL L-1, and the number of seeds was 37.589 mL L-1. AMF dosage of 10 g plant-1 gave the best growth and yield of soybean plants.

Abstract

Soybeans are the third most important commodity after rice and corn. Soybeans are also a commodity rich in protein. Soy serves as a very important source of vegetable protein to improve people's nutrition because in addition to being safe for health is also relatively cheap compared to animal protein sources. Ultisol has a wide distribution but has constraints to be used as a medium of cultivation plants. The addition of some types of ameliorating or soil reformers such as chicken manure, cow manure, and composting oil palm bunches (OPB) is expected to overcome ultisol fertility. The purpose of this study was to compare the influence of varieties on the growth and component of soybean crop yields in Ultisol, compare the influence of ameliorating type on the growth and component of soybean crop yields in Ultisol, and get the interaction between the type of varieties with the type of amelioration to the growth and components of soybean crop yields in Ultisol. The research was conducted from February to May 2019 in the experimental garden of Integrated Agricultural Zone of the Faculty of Agriculture UNIB Medan Baru, Bengkulu City. This study used a Complete Randomized Design (CRD) that was compiled factorially with 3 times. The first factor is the variety type Anjasmoro and Gepak Kuning, the second factor of amelioration type is control (without amelioration), chicken manure 15 tons ha-1, cow manure 15 tons ha-1, husks burn 15 tons ha-1, and compost oil palm bunches (OPB) 15 tons ha-1. The results showed that the Gepak Kuning variety showed better growth than the Anjasmoro variety while the Anjasmoro variety showed better results than the Gepak Kuning variety. Chicken manure is the best type of amelioration compared to cow manure, rice husks, and compost OPB against the growth and component of soybean yields in Ultisol, and there is interaction in the Gepak Kuning variety with chicken manure amelioration and compost OPB.

Abstract

The application of a wed-based liquid organic fertilizer can increase the production of black soybeans (Glycine Max L. Merril). The study aimed to identify the best source and dose of liquid organic fertilizer (LOF) for black soybean growth and yield. The researchers used a three-times-repeated Completely Randomized Design (CRD) using a factorial layout. The first factor was the source of LOF, which included Siam weed (Chromolaena odorata, L.), Goat weed (Ageratum conyzoides L.), and yellow creeping daisy (Wedelia trilobata L.). The second factor was the concentration of weed-based LOF, consisted of water (control treatment); 12 ml/L; 16 ml/L; 20 ml/L. The results of the study show, weed-based LOF, namely LOF Yellow creeping daisy, Goat weed, and Siam weed, resulted in no significant difference in the growth and yield of the black soybean. Except for the variables of root fresh weight and number of pods per plant, the variation in concentration of weed-based liquid organic fertilizer had no significant effect on plant growth and yield.

Abstract

Cultivation problems on marginal Ultisol involved low soil organic matter content, low water holding capacity and low soil aggregate stability. These constraints determined cabbage growth because of root crop development limited and plant nutrient uptake inhibited. Application of chicken manure could overcome the marginal constraints through improving soil aggregate stability and soil moisture content on the marginal Ultisol as well as the cabbage growth increased. The purpose of this study was to evaluate the soil aggregate stability and soil moisture in Ultisol as affected by the chicken manure applied and the cabbage growth improvement. This study was conducted from December to February, 2021 at Agriculture Station, Faculty of Agriculture, University of Bengkulu lying on ±100 m above sea level. The experiment design used was Completely Random Block Design (CRBD) with the chicken manure applied involved 5 doses; 7.5 tons ha-1, 15 tons ha-1, 22,5 tons ha-1, 30 tons ha-1, and without the manure as a control treatment. From the variance analysis (ANAVA) in the level of 5%, the chicken manure applied was significantly influence the improvement of soil aggregate stability and soil moisture content as well as the cabbage growth. With Duncan Multiple Range Test (DMRT), the dose of 7.5 tons ha-1 gave the highest value of the soil aggregate and soil moisture improvement. Furthermore, the chicken manure application of 7.5 tons ha-1 improved significantly the cabbage stem diameter at the age of 15 days, 30 days, and 45 DAP. The 7.5 tons ha-1 manure applied also gave significantly a number of leaves at the age of 15 days and 30 DAP. The height of plant was significantly influenced when the cabbage growth 15 DAP with 15 tons ha-1. In short, the chicken manure applied with 7.5 tons ha-1 gave the soil aggregate stability, the soil moisture, and cabbage growth improvement.

Abstract

Vermicompost is one of increasingly applied organic fertilizer to many vegetable crops in order to reduce the dependency on synthetic fertilizer, including the use of urea as nitrogen source. This experiment aimed to determine the best dosage combination of vermicompost and synthetic urea on growth and yields of mung bean grown in Ultisols. This experiment was arranged in a randomized complete block design  with three replicates. Treatments consisted of  (1) control, no urea and no vermicompost, (2) 50 kg/ha urea + no vermicompost, (3) 40 kg/ha urea + 3 Mg/ha vermicompost, (4) 30 kg/ha urea + 6 Mg/ha vermicompost, (5) 20 kg/ha urea + 9 Mg/ha vermicompost, (6) 10 kg/ha urea + 12 Mg/ha vermicompost, and (7) 0 kg/ha urea + 15 Mg/ha vermicompost.  Results indicated that the combination of urea and vermicompost increased plant height, leaf number, branch number, number of nodules/plant, shoot to root ratio, number of pods/plant, number of pods/plot, grain dry weight/plant, grain dry weight/plot, and total yield /ha, but not days to flowering and weight of 100 grains. The best combination to increased growth and yields of mung bean was 12 Mg/ha of vermicompost in combination with 10 kg/ha of urea.  This combination  produced the highest grain yields/ha (2.1 Mg/ha).
