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

This study aims to study the interaction between varieties and the correct dose of potassium fertilizer, determine the right dose of potassium fertilizer and the appropriate variety of sweet potato in Ultisol. In this study, the research design used was a completely randomized block design (RAKL) with two (2) factors with three replications. The first factor is three varieties of sweet potato, namely Cilembu, Atin 3, and Beta 1. The second factor is the dose of KCl fertilizer which consists of 4 levels of dosage, namely 0 kg ha-1, 150 kg ha-1, 300 kg ha-1, and 450 kg ha-1 KCl fertilizer. The results showed no significant interaction between the dose of KCl fertilizer and the three varieties of sweet potato. The Antin 3 variety produced the most extended tendril length compared to the other two varieties. The lowest number of branches was produced by Beta 1 variety. The Cilembu variety produced the most significant tuber weight per plot and estimated weight per plot. The Cilembu variety is proven to have the highest level of sweetness.

Abstract

Understanding the relation of agroecosystem types, ages, and soil properties are vital in maintaining good quality soil. This study aims to explore the variation of selected soil properties with agroecosystem types and ages. The research has been conducted in North Bengkulu, Indonesia. Soil properties on agroecosystems of 5-yr, 10-yr, 15-yr oil palm plantation, 5-yr, 10-yr, 15-yr rubber plantation, food cropland, and scrubland were evaluated. The study found that soil in oil palm and rubber plantations of any age have a similar texture, bulk density (BD), and actual soil moisture (ASM). All plantation agroecosystems and scrubland have higher clay and lower silt content than that in food cropland. In addition, the scrubland has the highest ASM content among the agroecosystems. On the other hand, both agroecosystems enhances soil chemical properties than food cropland and scrubland as indicated by the improvement of organic-C, total-N, available P, exchangeable K and CEC of Ultisols. Older plantation also provides higher soil chemical improvement than younger one. This finding is significant for management of sub optimal soil mainly Ultisols for oil palm and rubber plantation.

Abstract

Soybean is a type of secondary crop that is widely cultivated and used as raw material for tofu, tempe, milk, and so on by the people of Indonesia. Soybean consumption is always increasing but soybean production has decreased. This study aims to obtain the optimum dose of Bokashi fertilizer on plant growth and yield in Ultisol. The study was carried out in Medan Baru, Kandang Limun Village, Muara Bangkahulu District, Bengkulu City from December 2018 to April 2019. This study used a Completely Randomized Block Design (RCBD) with one factor, namely the dose of Bokashi fertilizer with five levels, namely 0 tons ha-1, 25 tons ha-1, 35 tons ha-1, 45 tons ha-1, and 55 tons ha-1. The results showed that the optimum dose of Bokashi fertilizer was not found in the growth component or yield component. The dose of Bokashi fertilizer had a significant effect (p<0.05) on the growth of Bokashi and the number of leaves.

Abstract

The research aimed to determine the optimal population ratio at each frequency of weeding for the growth and yield of maize. It was carried out from February to May 2020 in the field. There are 2 treatment factors tested arranged in a splite plot design, which was repeated 3 times using a completely randomized block design (CRBD). The first factor is the frequency of weeding as the main plot (Main Plot) consisting of no weeding, 1 x weeding (21 DAS), 2 x weeding (21 DAS and 42 DAS). The second factor is the ratio of the population as sub-plots, consisting of 100% corn + 0% peanuts, 80% corn + 20% peanuts, 60% corn + 40% peanuts, 40 % corn + 60% peanuts, 20% corn + 80% peanuts. The results showed that the growth and yield of maize in the intercropping system with peanuts gave the same response to the population ratio at all weeding frequencies. The planting density of 40% maize + 60% peanuts produced the highest response on the variables of stem diameter (24.675 mm), plant fresh weight (667.51 grams) and biomass weight (79.924 grams). While the highest response to weeding frequency was 2 times (21 DAS and 42 DAS) only on plant fresh weight (588.08 grams).

Abstract

Application of organomineral fertilizer (OMF), which is the product of the inclusion of zeolite and  palm oil compost in urea needs to be studied to determine its appropriate dose for the growth and yield of shallots and N substitution. This pot experiment was conducted from October to December 2020 at the Teaching and Research Field of Agriculture Faculty and consisted of five treatments arranged in a completely randomized design with five replications. The treatments were (1) 1.0 g urea, (2) 0.5 g urea + 1.15 g OMF, (3) 0.5 g urea + 2.30 g OMF, (4) 0.5 g urea + 3.45 g OMF, and (5) 0.5 g urea + 4.60 g OMF. The results showed that combined application of 0.5 g urea + 4.60 g OMF produced the highest values of plant height (30.60 cm), number of leaves (30.90), fresh weight of tubers per clump (30.90 g),  dry tuber weight per clump (24.3 g), and tuber diameter (16.25 mm). The incorporation of zeolite and palm oil compost in urea reduced the application rate of urea up to 50% without reducing the growth and yield of shallot. Thus, N fertilizer use can be enhanced if urea is co-applied with zeolite and palm oil compost.
