Abstract

Rice fields that were intensively cultivated by the application of chemical fertilizers for a long time may experience declining rice production, as the soil ages. Therefore, it is necessary to assess the fertility of the paddy soil for rice cultivation. Site-specific balanced fertilization is determined based on soil test results that represent the in situ soil chemical properties. This study aims to analyze the fertility level of paddy fields and determine the optimal amounts of nitrogen (N), phosphorus (P), and potassium (K) fertilizers for rice growth, considering the soil fertility status in Marga Cinta, Belitang Madang Raya District, Ogan Komering Ulu Timur of South Sumatra, Indonesia. The study employed a random sampling method, with a total of 6 samples collected by drilling at a depth of 0 - 30 cm, and then composited. The results revealed that the fertility of the paddy soil at the study site was relatively low, with an average pH of 5.32, organic carbon content (C-Organic) of 0.67%, cation exchange capacity (CEC) of 9.85 cmol/kg, base saturation of 21.05%, total nitrogen (N-total) of 0.10%, available phosphorus (P-available) of 1.87 mg/kg, and exchangeable potassium (K-exchangeability) of 0.10 cmol/kg. Based on these findings, the recommended fertilization amounts are 199.89 kg/ha of urea, 147.91 kg/ha of SP-36, and 28.45 kg/ha of KCl.

Abstract

Trigona bee (Trigona spp.) is a species of honey-producing bee that does not have a sting (Stingless bees). This bee is small in size and plays an important role as a pollinator of flowering plants. Research was conducted from June to July 2021 in Baturaja City, Ogan Komering Ulu Regency, South Sumatra. The purpose of this research was to study the species of Trigona bees (Trigona spp.) visiting various flowering plants and the species of flowering plants visited by these bees. The research method involved purposive sampling and direct observation in the field. Observations were made by identifying bee species present on several flower plants. Trigona bees predominantly used plants in the flowering phase as a food source due to their abundant nectar and pollen production. The field observations revealed 11 species of flowering plants favored by Trigona bees, namely Kembang kertas (Zinnia elegans), Jambu air (Syzygium aqueum), Air mata pengantin (Antigonon leptopus), Kelengkeng (Dimocarpus longan), Melinjo (Gnetum gnemon), Cabai (Capsicum annuum), Seri (Muntingia calabura), Palem (Dypsis lutescens), Matahari (Helianthus annuus), Santos lemon (Xanthostemon chrysanthus), and Belimbing (Averrhoa carambola). The most commonly found species of Trigona spp. was Heterogona itama, observed on the bridal tears flower (Antigonon leptopus).

Abstract

The aim of the study was to examine the effect of adding acidifier with inulin and papain enzymes in the ration on the differential leukocytes in turkeys during the growth period. The research material consisted of 80 male turkeys aged 12 weeks with an average weight of 1165 ± 62.24 g, an acidifier consisting of a mixture of lactic acid, propionic acid, and formic acid, and inulin sourced from dahlia tuber extract and the enzyme papain. The feed ingredients used in this study were corn, soybean meal, fish meal, rice bran, premix, CaCO3, lysine, and methionine. The research design used a completely randomized design with 5 treatments and 4 replications. The treatments applied included T0 (control diet/RK), T1 (RK + 1% acidifier), T2 (RK + 1% acidifier + 1.2% inulin), T3 (RK + 1% acidifier + 0.5% papain enzyme), and T4 (RK + 1% acidifier + 1.2% inulin + 0.5% papain enzyme). Parameters measured included heterophiles, lymphocytes, leukocytes, and total plasma protein. Data were analyzed using variance at the 5% level and Duncan's test of significant differences at the 5% level. The results showed that the addition of acidifier with inulin and papain enzymes had a significant effect (p<0.05) on the differential leukocytes (heterophiles, lymphocytes, leukocytes, and total plasma protein). The conclusion is that the addition of 1% acidifier + 1.2% inulin + 0.5% papain enzyme (T4) can maintain the health condition of the body, as observed from the differential leukocytes in male turkeys during the growth period.

Abstract

One of the factors of soil pollution in paddy soil is the heavy metal lead (Pb). Lead is an element that is not essential for plants, with a content ranging from 0.1 - 10 µg/kg, and in various plants, it normally ranges from 0.5 - 3.00 µg/kg. This study aims to determine the content of lead (Pb) in soil and rice plants, as well as some of the chemical properties of the soil in the central rice area located in Marga Cinta, Belitang Madang Raya District, East Ogan Komering Ulu, South Sumatra, Indonesia. This study used a detailed survey method with a working map scale of 1:9,000. The paddy field studied covered 96 hectares divided into 6 locations, which were sampled using a random sampling method. Each location had 5 soil drilling points, and composite samples were created. Soil sampling was carried out by augering at a depth of 0-30 cm. The results showed that the content of lead (Pb) in paddy soil ranged from 9.90 – 12.18 µg/g with an average of 10.56 µg/g, while the content of lead (Pb) in rice plants was below the detection limit of the tool, with a value of <0.0002 µg/g. The conclusion from the study was that the content of the heavy metal lead (Pb) in paddy soil and rice plants at the study site was still below the threshold.

Abstract

Mixing urea with natural materials that can reduce the rate of urea dissolution is known to increase the N availability replenished by inorganic fertilizers which absorbed by plants for growth and production.This study aimed to examine the effective of application of pellet N fertilizer prepared by coal fly ash- azolla and urea on the response of corn planted in acidic Ultisol. This pot experiment was performed in the greenhouse and soil analysis was conducted in the Laboratory of Chemistry, Biology and Soil Fertility, Soil Science Department, Faculty of Agriculture, Sriwijaya University. The research was arranged using a completely randomized design with nine treatments and three replications. The treatments applied were a mixed composition materials (w/w) of 50% coal fly ash + 50% azolla, and 40% coal fly ash + 60% azolla respectively. Each composition (w/w) of 70% coal fly ash- Azolla mixture was then incorporated by 30% urea and compacted as pellets using a manual screw extruder. In addition, to compare the effect of pellet, it was done the other treatment by granular urea fertilizer only applied by immersing and sowing on the soil surface. The results showed that the application of N slow release using the pellet forms significantly increased N availability, plant N uptake, plant height and dry weight of corn. The N slow release as a pellet can reduce the dose of N inorganic fertilizer as urea by 25%. The response of corn at a dose of 0.75 times is not significantly different from the dose of 1 times the recommended dose of N.

Abstract

Maize crop is one of the agricultural commodity crops that have an important role in the agricultural sector because corn plants are needed in the supply of food, feed, livestock and other industrial needs. The condition of corn plants with high rainfall can result in the risk of flooding of corn plants, if the corn plants are always flooded continuously it will result in a decrease in corn production. Stagnant water is an abiotic stress that must be considered because it can result in an increase in H2O and a decrease in O2 in stagnant plants. Stagnant water or excessive water stress can result in decreased plant development and decreased production. The aim of the research was to look at the growth conditions of maize plants at various high groundwater levels. The best expansion was achieved in treatment P5 (groundwater table 30 cm from the soil surface) that is 212.67 cm and the lowest results were in treatment P2 (groundwater table 5 cm from the soil surface) with a plant height of 61.50 cm

Abstract

The utilization of wetlands as agricultural land requires specific processing techniques, which are relatively expensive and unaffordable for local farmers. The optimization of wetlands as agricultural land by local farmers is usually made by elevating a certain part using the adjacent soil material known as Surjan system. The land management using Surjan system increases the diversity of agricultural products and deals with inundation problems. However, its environmental impact has not been widely studied. The research was conducted by observing the land with Surjan system in Kulonprogo area to determine its characteristics. Interviews with farmers were conducted to determine land management techniques. Soil and gas emissions samples were taken based on the age of the crop. The characteristics of land with Surjan system and conventional rice field were then compared to determine the difference, and the implications of the two agricultural lands on the environment are discussed. Surjan system can increase land productivity, and it can be adopted easily by farmers in other areas with inundation problems. This system is a planting system consisting of mound (the raised beds) and tabukan (the sunken beds that remain inundated). The mound part can be planted with secondary crops, horticulture, and other dryland crops, while the tabukan part can be planted with rice and used for mina padi (rice-fish) farming system. Surjan system provides benefits for environmental management through the prevention of floods and eutrophication, as well as reduction of greenhouse gas emissions in the atmosphere. Land management through Surjan system affects soil pH, redox potential, and organic matter. Land with Surjan system produces lower methane gas emissions than conventional rice fields. It produces methane gas of 4.06 - 45.73 µg / m2 / minute, with soil pH, redox potential, and organic matter of 6.65 - 7.69, (-) 49 - 10 mV, and 1.28 - 3.59%, respectively

Abstract

In Indonesia, onion cultivation uses bulbs, which disrupts stocks of consumtion and trade quite significantly. One way to reduce the need for bulbs from onions is to use True Shallot Seed (TSS). Onion of TSS can reduce production costs, and is practical in shipping compared to bulbs. One of the activities in the cultivation of TSS is the preparation of strong, uniform and healthy of seedling. This study aims to examine the appropriate composition of organic matter as a planting medium to accelerate the germination time of various cultivars of TSS. The planting medium tested was a mixture of soil, rice husk, cocopeat and sawdust. This study used a complete randomized block design which was arranged in factorials. The first factor was the variety and the second factor was mixing of organic matter. Mixing organic matter with the soil before planting onion seeds led to an increase in soil pH from 0.77 to 1.51. Mixing soil with organic matter before implementation increased the pH of the media, CEC, WHC, and decreases the bulb density. After germination, the husk and cocopeat mixture showed a pH (5.9), CEC (1.62 mS.cm-1), bulb density (0.3 g/cm3) and WHC (162%). The combination of rice husk and cocopeat as the growing medium (4,9 days), the Sanren cultivar (7,3 days) exhibited the fastest germination and seedling growth rate compared to other cultivars and mixed growing media.

Abstract

Agriculture serves as a critical sector underpinning the livelihood of the Indonesian population.. Thus the implementation of this sector involves the use of fertilizers as inputs. However, A prevalent misconception among farmers is that increased fertilization invariably leads to enhanced yield. Excessive fertilization using inorganic compounds, such as phosphorous (P) can elevate levels of Cadmium (Cd), which is a potentially toxic metal for the environment and humans. Therefore, this study aimed to investigate the concentration of the heavy metal cadmium (Cd) in both soil and rice plants in Marga Cinta, Belitang Madang Raya District, East Ogan Komering Ulu Regency, South Sumatra, Indonesia. The method involved a comprehensive survey approach and spanned across 96-hectares of paddy fields, which were divided into six distinct locations. Each location comprised 16 hectares of rice fields, with five sample points drilled to a depth of 0-30 cm. The results showed that the content of Cd in paddy soil and rice plants had exceeded national food safety standards. Hence, farmers were advised to balance their use of phosphorus-rich fertilizers with organic ones, mitigating the rise in soil Cd content. This balance necessitates a reduction in the usage of other chemical fertilizers, favoring organic fertilization methods to promote phytoremediation
