<![CDATA[Corn is one of the important food commodities after rice and wheat. Corn acts as a food, feed, and industrial ingredient. The need for corn in Limapuluh Kota Regency is very high along with the development of chicken farming businesses that require corn as the largest feed mixture. However, the need for corn has not been met by corn production in this Regency. The low corn production is more due to the low supply and use of superior corn seeds, as well as low soil fertility. One effort to increase soil fertility is the use of KoHeA+MF compost. The purpose of this study is to ascertain how the production of KoHeA+MF hybrid seeds is impacted by the dosage of KoHeA+MF compost and the quantity of inorganic fertilizer that can be substituted. The study was conducted from May to September 2024 at the seed production land of PT. AZUMA Situjuah, Limapuluh Kota Regency, West Sumatra. The study used a Randomized Block Design (RBD) with 5 treatments, including: 100% inorganic fertilizer (Control), 75% inorganic fertilizer + 10 tons/ha KoHeA+MF, 50% inorganic fertilizer + 10 tons/ha KoHeA+MF, 25% inorganic fertilizer + 10 tons/ha KoHeA+MF, and 0% inorganic fertilizer + 10 tons/ha KoHeA+MF.The application of various doses of inorganic fertilizer combined with 10 tons/ha KoHeA+MF affected soil fertility, especially the increase in soil pH (H2O), organic C, total N, P2O5, K2O, and soil Ca. The application of inorganic fertilizer + 10 tons/ha KoHeA+MF significantly affected vegetative growth, yield components and corn kernel production of JH37 corn. The optimal dosage for dry corn kernel production is 10 tons/ha of KoHeA+MF and 75% inorganic fertilizer.]]>

<![CDATA[The impact of agricultural activities such as the application of organic and chemical fertilizers will be causing a Cadmium (Cd) contamination. Information on the presence of Cadmium (Cd) both in the soil and Rice Plants in North Talang Ubi, Talang Ubi District, Penukal Abab Lematang Ilir of South Sumatera, Indonesia is still very limited and difficult to obtain for the issue of heavy metal of cadmium (Cd). This study aims to analyze the cadmium content in paddy fields with two different cultivation systems, namely organic and conventional farming systems. This research was a survey method and soil analysis conducted in two locations which were soil from Rejosari with organic farming system and other coming conventional farming system. The soil sampling was done from March 2023 to June 2023. The results of this study showed that the cadmium content in soil in the two cultivation systems is still below the cadmium quality standard, with the highest soil Cd content found 0.00478 mg/kg in the conventional cultivation system where the threshold limit is 0.5 mg/kg. The cadmium content of rice shoot and roots in the two cultivation systems was also still below the quality standards of cadmium, where the highest Cd content was found around 0.03303 mg/kg in the conventional cultivation system where the threshold limit was 0.1 mg/kg. ]]>

<![CDATA[This study examines the financial feasibility of different replanting patterns for oil palm plasma and assesses farmers’ concerns regarding replanting decisions. The research was conducted in three districts of South Sumatra (OKI, Muara Enim, and Musi Banyuasin) with plasma farmers as respondents. Three financing patterns were analyzed: self-financing through savings, insurance-based financing, and bank loans. The research used a survey method and sampling was determined with a balanced random sampling technique with 90 respondents. The research concluded that the financing pattern of oil palm replanting can be done through savings, insurance, and bank loans. The best financing pattern for replanting is conducted by using their savings because it can produce the highest net B/C value; NPV; and the shortest payback period. Sensitivity analysis showed that Fresh Fruit Bunch (FFB) price reduction is the most sensitive for the financing patterns of their savings and bank loans, however for the financing patterns of insurance, the decrease in FFB production is mentioned as the most sensitive. The government has to maintain stable FFB pricing, and it is advised that they use their funds, which are arranged by KUD, to support the oil palm replanting. Five factors -complexity, compatibility, relative profitability, trialability, and observability - will be used to gauge farmers’ concerns about oil palm replanting. ]]>

<![CDATA[Agroforestry is a land use system that integrates agricultural and forestry crops in the same area, providing a balance between production and conservation for social, economic and ecological benefits. Farmers at the Lembah Bukit Besak Village Forest Institute, Tanjung Beringin Village, South Merapi District, have implemented this system. The research aims to identify planting patterns and composition of agroforestry plants, evaluate the most optimal plants to increase income, and formulate strategies for adopting the best planting patterns. This study used a census method to collect data from 75 farmers in the Rimba Bukit Besar Village Institution group. After conducting a sampling method using a purposive stratified random sampling method, 24 farmer respondents were obtained. The research results show two main planting patterns: a random mixture, applied by 66.67% of farmers, and tree along border pattern, applied by 33.33%. The most profitable crops are coffee, rubber, jengkol, durian and eggplant (Solanum melongena). The "Tree Along Border" pattern has proven to be more effective in preventing erosion and providing shade for plantation and vegetable crops compared to random mixture patterns which focus more on forestry and plantation crops. The strategy for adopting the best planting patterns includes the development of pilot demonstration plots, intensive counseling, dissemination of information on research results, as well as the involvement of the government and related agencies in supporting superior commodities. This approach is expected to increase farmers’ income and welfare in a sustainable manner. From the adoption of additional horticultural crop types, farmers’ income increased by 9.264 to 30.83 percent when compared to the application of a combination of plant types without horticultural commodities.]]>

<![CDATA[Rice (Oryza sativa L.) is one of the main food commodities in Indonesia and has a strategic role in national food security. High quality rice production is a major factor in meeting the increasing consumption needs of the community. However, agricultural conditions in Indonesia still face various challenges, especially in rainfed rice fields which are highly dependent on rainfall and often experience problems in crop production. This research was conducted in Prabu Menang Village, East Merapi District, Lahat Regency, South Sumatra Province, from January to April 2024. The method used was quantitative research with a split plot design. The main plot was a combination of fertilizers consisting of three treatments: (1) NPK (300 kg/ha), Urea (150 kg/ha), and LOF (Liquid Organic Fertilizer) (25 ml/L) ; (2) NPK (300 kg/ha) and Urea (150 kg/ha) fertilizer; and (3) LOF (25 ml/L). The subplots consisted of two rice varieties, Nutri Zinc and Inpari 32, so there were 6 treatment combinations repeated 4 times, resulting in a total of 24 units experimental . This study aimed to analyze the effect of fertilizer combinations on the growth and yield of Nutri Zinc and Inpari 32 varieties in rainfed fields. The results showed that the combination of fertilizers had significant effect on plant height and number of tillers. Inpari 32 variety was with superior higher plant height and more tillers than the Nutri Zinc variety. The combination of NPK, Urea, and LOF fertilizers with the Inpari 32 variety produced the highest productivity of 4.67 tons/ha, while Nutri zink variety with the same fertilizer is 4.41 tons/ha. The combination of NPK and Urea fertilizers with the Inpari 32 variety is 4.60 tons/ha and Nutri zink variety is 4.35 tons/ha. The use of LOF alone resulted in a lower number of tillers and productivity, 3.92 tons/ha for Inpari 32 variety and 3.66 tons/ha for Nutri Zink variet. ]]>

<![CDATA[Agriculture is a primary source of methane (CH4), which contributes to global warming. Globally, there is a significant increase in methane emissions due to the expansion of the livestock industry. Reducing methane emissions is necessary to avert a climatic catastrophe. This article compiled and reviewed 136 published articles and online database information on greenhouse gas management from 2017 to 2024. The objective was to ascertain which technology reduces methane to the bare minimum to mitigate climate change. Mitigation systems assessed included manure acidification, animal housing systems, manure storage systems, temperature, filtration, vermicomposting, composting, biochar addition, feed additives, feeding technology, digester technology, and breed selection. It turned out that no single abatement technology can eliminate methane. Methane emissions will continue to increase if one-factor abatement is the main focus. An integrated strategy that incorporates economic and environmental assessment of livestock trade-offs, nutrition, feed quality, source, type, and breed, and feed conversion efficiency can significantly reduce methane emissions. Simulating the Earth’s carrying capacity and human demand for livestock products can reduce methane.]]>

<![CDATA[Precision of fertilizer is an approach that directs the use of fertilizers in a rational, efficient, and targeted manner, so that plants obtain sufficient nutrients for optimal growth without causing waste or negative impacts on the environment. This study aims to determining the doses of N, P, and K fertilizers that are appropriate for swampland by implementing a site-specific fertilization approach using in situ soil analysis. This research used a systematic method with 15 sample points, Soil sampling was conducted using a composite method and soil drilling with soil depth of 0-30 cm. The parameters observed were N-total, P-available, k-exchangeable, soil pH, and C-organic. The study found that the soil in Ulak Bedil Village exhibited highly acidic conditions (pH 3.80–4.47), with varied nutrient availability. Based on soil N, P, and K analysis and rice plant nutrient requirements, site-specific fertilizer recommendations were determined. The recommended fertilizer doses are 91.30 kg ha−1 for urea, 31.03 kg ha−1 for SP-36, and 109.65 kg ha−1 for KCl. This research provides a practical guideline for the application of site-specific fertilization to rice cultivation in swampland, in order to increase yields while reducing negative impacts on the environment.]]>

<![CDATA[The use of Precision Agricultural Technology (PAT) is increasingly becoming the main focus in efforts to increase the efficiency of rice production in Indonesia. This research aims to identify the benefits, challenges and environmental impacts of implementing PAT on rice fields owned by PT. Buyung Putra Pangan in Pelabuhan Dalam Village, Pemulutan, Ogan Ilir, South Sumatra. The research method used is a combination of qualitative and quantitative approaches, through literature reviews from various relevant sources as well as observations and interviews in the field. The research results show that PAT has great potential in increasing the efficiency of rice production through the use of advanced technology such as soil sensors, drones for fertilization, seed dispersal, and eradication of plant pest organisms. The main benefits of PAT include increasing productivity, reducing production costs, and preserving the environment through more efficient use of inputs. However, implementing PAT in rice fields owned by PT. Buyung Putra Pangan still faces challenges, such as high initial investment costs, training requirements for farmers, and limited supporting infrastructure. Apart from that, there are also environmental impacts that need to be considered, such as the risk of soil and water contamination due to excessive use of pesticides and chemical fertilizers. Therefore, collaborative efforts are needed between the government, research institutions, the private sector and farmers to overcome these challenges and maximize the benefits of PAT in increasing the efficiency of rice production in a sustainable manner.]]>
