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

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

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

Abstract

Sweet corn is a food crop that has a sweeter taste than ordinary corn. It has high economic value and has a shorter harvest time. The demand for corn is increasing in Indonesia but corn production is not sufficient to meet it. For this reason, efforts to increase sweet corn production are needed to consume the people. The purpose of this study was to determine the effect of oil palm bunch ash and cow manure ameliorants on the growth and production of sweet corn (Zea mays saccharata Sturt) on peat soil. The pot experiment was conducted in Bandar Agung Village, Lalan District, Musi Banyuasin, South Sumatra of Indonesia dated from December 2022 to March 2023. This study used a Randomized Factorial Block Design which consisted of 2 factors which were the first factor was dose of oil palm bunch ash consisting of control, oil palm bunch ash at 20 tons ha-1 and 60 tons ha-1. The second factor was dose of cow manure at control, 42 tons ha-1 and 84 tons ha-1. Total treatment was 9 combinations and it were repeated 3 times. For each treatment was left 2 plant samples. The results showed that no significant effect for plant height, number of leaves, plant fresh weight and plant dry weight. Application of 60 tons ha-1 of oil palm bunch ash + 42 tons ha-1 of cow manure showed the best combination results on sweet corn growth because it has the highest found on each variable observed. Keywords: Ameliorant, cow manure, oil palm bunch ash, peat, sweet corn

Abstract

Mustard greens are one of the vegetable commodities plants. The part used is the young leaves, which can be processed into traditional medicinal and vegetable ingredients that benefit human health. This research aims to determine the level of shade tolerance on the growth and yield of mustard plants and determine mustard varieties that are tolerant of minimum sunlight conditions. This research was carried out in experimental fields using artificial fields in June – July 2023. This research used a split-plot design with 2 factors. Tafif shade as the main plot consists of no shade 0%, 55%, 70%, and 95%. The sub-plot varieties consist of the Tosakan variety and the Kumala variety. The results of the research indicate that sunlight intensity reduction negatively impacted the growth and yield of mustard plants. However, under 55% shade conditions, there was no significant difference observed in the growth and yield of mustard plants compared to those grown without shade. The Tosakan and Kumala varieties did not show any differences in the growth or yield of mustard plants.

Abstract

Tidal lowland is a marginal land characterized by low pH, deficient  nutrients, and salinity. Despite these challenges, El Niño phenomenon often occurs during the second planting season, resulting in long droughts. However, tidal lowland must be used for cultivation due to the need for rice and the land should be treated accurately. Therefore, this research aimed to address the issues by improving the efficiency of rice cultivation on tidal lowland through precision farming practices. A survey and land analysis were conducted in tidal lowland of B typology in Delta Saleh, Indonesia, from March 2023 to June 2023. In this precision farming practice, water management was highly prioritized, starting from tertiary channels such as optimizing sluice gate operations and monitoring water levels in channels and groundwater. Additionally, pH, CEC, and C-Organic analysis were also carried out in rice cultivation, as showed by the  equation Y = 0.15 - 0.001 pH + 0.000 CEC + 0.000 C-Organic. The highest production yield was 2.05 tons/ha in P5, with the SEW-10 value during cultivation activities being 778 cm and the number of days above -10 reaching 84. Moreover, the efficiency of rice cultivation was improved through precision agricultural practices by using valve sluices and levees.

Abstract

Recently, people have suffered from many serious illnesses, such as  kidney, cancer, osteoporosis, etc. One of the triggers is that the food eaten by human is not free from heavy metals. These heavy metals enter through the food chain during the crop cultivation. These heavy metals can come from artificial agrochemical inputs (such as synthesis P fertilizers and pesticides). One way to avoid the entry of heavy metals into plant is by implementing organic farming. Organic farming is an agricultural system that does not use synthetic chemical. The implication of organic farming are (1) maximizing the use local resources, (2) minimizing the use of chemical inputs, (3) ensuring biological functions, (4) maintaining a diversity of plant and animal species, (5) creating an attractive overall landscape that provides satisfaction for local communities, and (6) increasing the intensity of plants and animals in the form of polyculture, agroforestry, crop/animal systems integrated livestock etc. If organic farming principles are followed consistently then the food produced will be healthy and safe for humans and animals and save for land sustainability to support smart farming. Another benefit of organic farming is that natural resources will be sustainable and the environment will be protected from pollution and damage. To convince the Indonesian and global community, the organic products produced must be certified independently, the basis of which is SNI 6729-2016.

Abstract

Sorghum (Sorghum bicolor L. Moench) plant is native to tropical and subtropical countries with high suitability for planting on marginal land. Therefore, this research aimed to determine the use of dolomite and vermicompost in tidal swamp soil for the growth and yield of sweet sorghum plants at the Experimental Garden and the Chemistry, Biology and Soil Fertility Laboratory, Department of Soil Science, Faculty of Agriculture, Sriwijaya University. A factorial randomized complete block design (FRCBD) consisting of two factors was used. The first factor was dolomite namely 0 ton.ha−1, 6 ton.ha−1, 9 ton.ha−1, and 12 ton.ha−1, while second factor was vermicompost including 0 ton.ha−1, 3 ton.ha−1, 6 ton.ha−1, and 9 ton.ha−1. The results showed that the application of Dolomite had a very significant effect on soil pH, N-total, P-available, and potassium exchangeability. In addition, dolomite increased plant height, number of leaves, chlorophyll content, fresh and dry weight shoot, number of grains, and weight of 1000 grains.

Abstract

This study investigates the adoption of Climate-Smart Agriculture (CSA) practices among predominantly traditional rice farmers in South Sumatra, Indonesia, and proposes strategies for enhancing resilience to climate variability. A total of 98 farmers across nine districts participated in  structured surveys and in-depth interviews. The results showed a reliance on modern machinery for land preparation (62.8%) alongside a considerable use of traditional tools (26.5%). High awareness of climate change (87.9%) and its impacts, along with a substantial understanding of the negative effects of chemical fertilizers (67.7%), were observed. The use of weather forecasts by 34.7% of respondents highlighted the importance of reliable climate information in agricultural decision-making. Adaptive practices for drier conditions include water management (40%) and crop management methods (25%), while improved drainage (40%) and other flood prevention measures (35%) were commonly adopted for wetter conditions. Despite these efforts, 50% of farmers reported decreased productivity during dry seasons due to the significant impact of irregular rainfall, while approximately 42% managed to increase productivity during wetter conditions through adaptive practices. To enhance CSA adoption, continuous education and awareness programs, promoting energy-efficient machinery and organic farming methods, and improving access to accurate weather forecasts are recommended. The development of resilient crop varieties and the provision of financial and technical support are also essential. Implementing these strategies can facilitate the integration of CSA into the farming system, ensuring a resilient and sustainable agricultural sector in South Sumatra that supports both productivity and environmental preservation, contributing to long-term food security and sustainable development in the region.

Abstract

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.
