Studies on the assessment of seed systems (sources) in relation to seed quality are scarce. This study was carried out to assess the different seed qualities (physical purity, physiological quality, and seed health) of bread wheat seed accessed through the existing seed sources (formal and informal seed sources) in Baso Liben district of the Amhara region, northwest Ethiopia. In addition, this study assessed the experience of farmers in seed production and management. Data were collected from 108 respondents using a semi-structured questionnaire and from farmers and local experts using focus group discussions. Seed samples were collected from 58 farmers (30 farmers who sourced seed from the informal system and 28 from the formal system) for laboratory testing. Data were analyzed using descriptive statistics and t -test (pairwise comparison) using SPSS v23.0. Results showed that about 32.4% of the respondents have experience in quality bread wheat seed production under contractual seed production arrangements with public seed enterprises. Results also revealed significant differences between formal and informal seed sources for various seed quality parameters. Seeds accessed from the formal sources have better physical purity, physiological quality, and 1,000 seed weight than seeds accessed from informal sources. Seed samples collected from the informal source were highly infected with Aspergillus flavus , Aspergillus niger , Chaetomium spp., and Fusarium spp., and seeds from the formal seed source were infected with Alternata spp. and Penicillium spp. Seed quality is a major concern for the seeds accessed from both formal and informal sources. Therefore, the seed quality control mechanisms of various stakeholders, including national and regional seed regulatory bodies, government organizations, research institutes, and seed producers/companies, should be given much attention at each stage of the seed value chain.","PeriodicalId":45740,"journal":{"name":"Open Agriculture","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135319809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Six districts from two regions were purposively selected based on their potential for chicken population. A total of 176 adult local chickens of both sexes were used to estimate the body weight, linear body measurements and visual assessments of phenotypic traits. The results indicated that the predominant comb type was single (90.9%) followed by pea comb (6.8%). The dominant plumage colour was a combination of different colours (66%), followed by black (14%). Yellow shank colour (59.1%) was dominant over other colours. The estimated overall mean values of body weight, body length, chest circumference, and shank length were 1.80 kg, 39.3, 31.3, and 8.8 cm, respectively. Males were significantly heavier than females (2.2 vs 1.3 kg; p < 0.05). The values of most linear body measurement traits were significantly different ( p < 0.01). The chest circumference was not significantly different across the studied districts. The present finding suggests that indigenous chickens in the study area possess unique genetic potentials that would be used for further breeding programs for optimum utilisation of these genetic resources by the rural communities.","PeriodicalId":45740,"journal":{"name":"Open Agriculture","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135601208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The SDGs have 17 targets, one of which is to eliminate hunger. In 2050, the world’s population is expected to reach 9.7 billion people. Improved soil and water management, according to the World Resources Institute, is one of the options for feeding 10 billion people sustainably by 2050. In comparison to conventional farming, smart and precision farming produces higher productivity at a lower cost. Based on the search for literature studies related to the development of agricultural technology, it was found that communication methods and online interfaces still require further improvement. The steps for developing the system are designing the architecture and end-to-end communication flow, designing use case diagrams, designing entity-relationship diagrams, designing user flow diagrams, implementing the system through code development, and finally testing the system. Planned communication and web design for precision smart agriculture are implemented effectively. The MQTT is used to communicate with the Node.js server worker. Data from numeric image feeds and images are directly processed by the system. The server will store all received data, including numeric data and live feeds, for future use. The back end of the website has many functions such as dataset management, device management, user administration, firmware management, control management, and live image feed management are some of the capabilities available. When 100 users access the system simultaneously, the RAM usage on the server is 167 MB. RAM utilization reaches 389 MB when 400 users access the system simultaneously. The limit for simultaneous user connections to the web interface is 400 users. The maximum number of devices that can be connected simultaneously via MQTT communication is 900.","PeriodicalId":45740,"journal":{"name":"Open Agriculture","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136305534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cover crops or crop residue mulching are considered sustainable agricultural measures because they prevent soil degradation and compaction and increase the soil ecological diversity. However, the impact of these on soil quality in fruit orchards in the Vietnamese Mekong Delta is not well studied. The present work aimed to assess the effect of cover crops (grass, pinto peanut) and rice straw mulching on change in soil chemical properties and productivity of pomelo. The 3-year (2019–2021) field experiment was conducted at Phu Huu Commune, Chau Thanh District, Hau Giang Province, Vietnam. Four treatments, control (no-cover crop), grass cover crop, mulching with rice straw (MRS), and pinto peanut cover crop were used. Soil samples were collected from the depth of 0–20 and 20–40 cm for analyzing soil pH, total nitrogen (TN), total phosphorus (TP), available phosphorus (AP), and soil organic matter (SOM). Results showed that MRS or cover crop by pinto peanut significantly decreased soil acidity in the topsoil layer. Soil fertility properties (TN, TP, AP, and SOM) at the depth 0–20 cm were greatly improved after the application of the mulched rice straw and cover crop by legume, thus improving pomelo yield. Further study is required to understand the effects of the cover crop with pinto peanut and rice straw mulching on the physical and biological properties of soil as well as nutrient uptake of pomelo orchards.","PeriodicalId":45740,"journal":{"name":"Open Agriculture","volume":"8 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67231815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is clear that sufficient agricultural efficiency cannot be achieved without fertilizers, but fertilizers must cause minimal damage to the soil. Microorganisms, such as spore-forming bacteria, actinomycetes, fungi, algae, and protozoa play an important role in the soil and keep soil healthy. One of the soil substances involved in reactions that take place in plants is cellulose. This study investigated the effect of potassium dihydrogen phosphate (PDP), synthesized (via conversion between potassium chloride and ammonium dihydrophosphate) and granulated with the addition of microcrystalline cellulose (MC), on plants (winter wheat Toras, Lithuania) and soil microorganisms. The data of plants fertilized with pure KH2PO4, ones fertilized with PDP granulated with MC, and grown without fertilizers were compared in this study. Scanning electron microscopy and differential scanning calorimetry analysis were used to characterize the obtained product. One-way analysis of variance was used to evaluate the differences of the mean values between groups. In all cases, the significance level was p ≤ 0.05. The effect of pure KH2PO4 on plant indicators was found to be lower than that of granular PDP with MC. The length of the leaves was 29.63 and 31.20 cm, green mass was 0.471 and 0.763 g, ash mass was 0.015 and 0.019 g, respectively. In addition, granular PDP with MC did not adversely affect the soil microorganisms because the number of any species of bacteria (Spore b., mineral nitrogen assimilating bacteria, cellulose degrading bacteria) did not decrease and a slight increase in the number of Actinomycetes (from 8.5 × 105 to 2.9 × 106 KSV/g) and molds (from 3.0 × 104 to 1.4 × 105 KSV/g) was observed. The granular PDP with MC that we developed and used have better physical properties, higher agrochemical efficiency and cause less harm to soil microorganisms compared to pure PDP.","PeriodicalId":45740,"journal":{"name":"Open Agriculture","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45238091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These techniques appear in the frameworks of the digital transition, where smart technologies bring relevant contributions, such as improving the efficiency of the economic sectors. This is particularly important for sectors such as agriculture to deal with the challenges created in the context of climate changes. On the other hand, machine-learning approaches are not easy to implement, considering the complexity of the algorithms associated. Taking this into account, the main objective of this research is to present a model to predict fertiliser costs in the European Union (EU) farms through artificial neural network analysis. This assessment may provide relevant information for farmers and policymakers in the current scenario where the concerns are to identify strategies to mitigate the environmental impacts, including those from the agricultural sector and the respective use of chemical resources. To achieve these objectives, statistical information for the EU agricultural regions from the Farm Accountancy Data Network was considered for the period 2018–2020.

Soil bacteria play a significant role in the nutrient cycle of soil, but their presence can be affected by abiotic stress, such as salinity. This study aimed to compare the chemical characteristics of slightly saline and non-saline rice soil and examine the bacterial community structure in both rhizosphere and bulk soil. We utilized 16SrRNA gene sequencing and performed arithmetic means clustering, a type of hierarchical clustering, on the samples collected from the rice fields of Cimrutu and Rawaapu Village in Cilacap Regency, Indonesia. Although the nutrient content was similar in both soils, there was a noticeable difference in their electrical conductivity (EC) despite the two locations being less than 4 km apart. The EC value in the Cimrutu soil suggests that it is non-saline, while the Rawaapu soil exhibits a low salinity level. The study found that Proteobacteria was the most prevalent phylum in saline rhizospheric soil. In contrast, Firmicutes was the most abundant group in saline bulk soil and non-saline rhizospheric and bulk soil. Additionally, Halothiobacillus, Thioalkalispira-Slvurivermis, and Acidothermus genera dominated the saline rhizospheric soil, suggesting that halotolerant microbes play a significant role as plant growth-promoting rhizobacteria in saline soil. The study provides valuable insights into cultured or uncultured bacterial populations and structure in saline and non-saline soil to develop future strategies related to salinity by introducing beneficial microbes.","PeriodicalId":45740,"journal":{"name":"Open Agriculture","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135802003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a case study approach with qualitative analysis, the study combined primary data from in-depth interviews and secondary data derived from various studies and reports from government organizations. The results show that there is a considerable gap between the government’s fertilizer budget and farmers’ actual needs, leading to coverage of only 37%, thus forcing farmers to purchase more expensive non-subsidized fertilizers. The inefficient distribution system results in delays and scarcity. As a result, there will be market and price dualism between subsidized and non-subsidized markets, as well as subsidized and non-subsidized prices. Enforcement of pricing regulations faces hurdles due to the black market. In addition, farmers use the “foster father” system to obtain credit. To improve fertilizer management, the study recommends a multifaceted approach: increased budget allocation, efficient distribution, strong enforcement of pricing regulations, and innovative financing solutions such as the Tani Card. These strategies, along with improved inter-agency coordination, aim to address challenges and increase the effectiveness of subsidized fertilizer policies.","PeriodicalId":45740,"journal":{"name":"Open Agriculture","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135662015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
