RESUMO

Compliance with feed safety standards and practices on the farm promotes sustainable livestock production and can positively affect the environment and human health. This study aims to examine farmers' on-farm adoption of feed safety practices and determine the differences in adoption according to the socio-economic characteristics of farmers. An online survey was conducted to collect the study data. The study participants consisted of 442 livestock farmers in Riyadh region, Saudi Arabia. The study findings revealed that farmers highly adopted categories of feed purchasing (77.9 %) and feed mixing and distribution (75.05 %), whereas they were considered as a moderate level adoption regarding feed storing (70.9 %). The cluster analysis results showed two main patterns of adoption- "high adopters" and "moderate adopters"-based on the average level of adoption for 25 feed safety practices examined. The cluster of "high adopters" accounted for 59.9 % of the sample and had higher average adoption in all practices examined. The findings revealed that there are significant differences between the two segments of farmers, corresponding to gender, membership in livestock association, extension contact, raising sheep, and feeding system. This study proposes the regular monitoring of farms to ensure strict adherence to feed safety regulations, with the implementation of awareness and capacity development initiatives pertaining to feed safety concerns.

RESUMO

The partnerships between agricultural cooperatives and development actors play a critical role in meeting development challenges and building cooperative sustainability. The objective of this study was to analyze the key characteristics of engagements established between agricultural cooperatives and other actors and determine their success level. An analytical framework was developed to highlight nine areas, namely partnership configuration, stakeholders, objectives of the partnerships, partnership types, partnership stages, communication methods, achieved outcomes, partnership evaluation, and partnership sustainability. The targets were all agricultural cooperatives building associations with other actors between 2016 and 2020 in Saudi Arabia. Therefore, the study covered 69 partnerships founded by 32 agricultural cooperatives. The results revealed that the cooperatives involved in partnerships essentially provide farming inputs and equipment for their stakeholders and capacity building and training purposes. The public sector was the leading actor that collaborated with agricultural cooperatives in inter-sector partnerships. The findings also showed that 55.1% of the partnerships were "strategic partnerships" in cases of both independent value formation and integrative partnerships. By focusing on mapping the partnerships, this study presents beneficial information for policy-makers working on how agricultural cooperatives dealt with the other actors and the lessons gathered to build future sustainability collaborations.

RESUMO

The issue of the agricultural cooperatives' sustainability in developing their businesses is gaining increasing prominence. Building partnerships between development actors and agricultural cooperatives has been considered an effective strategy for supporting financial capital and addressing sustainability issues collectively. Therefore, this study aimed to address the features and strengths of 33 partnerships established between the Beekeeping Cooperative Association in Al-Baha, Saudi Arabia, and other actors between 2016 and 2021. The analysis of the collaborations was based on six criteria: motivations, partnership planning, outputs, governance practices, outcomes, and sustainability of a partnership. Furthermore, we developed a weighted scoring model to control variable selection and submit the strength of each partnership. The findings indicated that most collaborations (45.5%) were signed with the private sector. Furthermore, the honey value chain development was the most frequent reason (69.7%) attracting the partners to engage in the partnerships. Some of the most critical environmental objectives targeted by the partnerships examined were enhancing bee habitat by the diversification of pasture species, management to increase the flowering period, and proper grazing management. All partners achieved their individual goals jointly in 54.5% of the partnerships analyzed. In terms of a partnership's strength, the findings also revealed that only three partnerships (9.1%) were characterized as strong partnerships. This study provides a better understanding of how agricultural cooperatives collaborate with other actors and a basis for assessing the strength of the partnerships. Such information is crucial for developing relevant policies to encourage cooperatives to engage in future sustainability partnerships.

RESUMO

The world faces a once-in-a-century transformation due to the COVID-19 pandemic, adversely affecting farmers' employment, production practices, and livelihood resilience. Meanwhile, climate change (CC) is a crucial issue limiting agricultural production worldwide. Farmers' lives, severely affected by extreme weather conditions, are resulting in the reduced production of major economic crops. The CC has drastically influenced the major agricultural sectors of Pakistan, leading to a significant decline in farmers' living standards and the overall economy. Climate-smart and eco-friendly agricultural practices can mitigate greenhouse gas emissions and ameliorate agricultural productivity under extreme environmental conditions. This paper highlights farmers' autonomous CC adaptation strategies and their influence on cash crop (maize for this study) yield under prevailing circumstances. The current study used a simultaneous equation model to examine the different adaptation impacts on adapters and non-adapters. The survey results of 498 maize farmers in rural Pakistan revealed that growers were aware of the recent CC and had taken adequate adaptive measures to acclimatize to CC. Farmers' arable land area, awareness level, and information accessibility to CC are the most crucial factors that impart a significant role in their adaptation judgments. However, most growers have inadequate adaptation strategies, including improved irrigation and the utilization of extensive fertilizers and pesticides. Using a simultaneous equation model of endogenous switching regression, the study found that farmers not adapted to CC were negatively affecting maize productivity. Therefore, this study suggests that policymakers pay attention to the countermeasures farmers have not taken to mitigate the impact of CC. In addition, policymakers should deliver appropriate adaptation strategies to assist growers in coping with climate-related natural hazards and ensure farmers' livelihood security, rural revitalization, and sustainable agricultural development.

RESUMO

The aim of this study was the isolation and molecular characterization of fungi from untreated refinery effluent by using multiple conserved genes. The Fungi isolated were characterized based on PCR amplification and genomic sequencing of the internal transcribed spacer region (ITS), partial ß-tubulin (BenA), calmodulin (CaM), and RNA polymerase second large subunit (RPB2) genes, along with morphological characterization. The obtained sequences were subjected to BLAST analysis and the corresponding fungal isolates were assigned species names after comparison with representative sequences available in GenBank. Fifteen (15) Fungi species belonging to four genera of Aspergillus, Penicillium, Fusarium, and Trichoderma with Aspergillus as the predominant genus were identified. Therefore these genes should be used as molecular markers for species level identification of fungi (especially Aspergillus and Penicillium as proven in this study.

RESUMO

Goal 17 of the sustainable development goals (SDGs) attracted attention to the importance of partnerships between governments, the private sector, and nonprofit organizations (NPOs) for sustainable development. This paper aims to analyze the processes of establishing and operating the partnerships between NPOs and other actors in terms of governance. The best practices for partnership governance were examined according to the partnering life cycle framework. A simple random sample of 184 NPOs in six regions of Saudi Arabia was selected for data collection. These organizations were analyzed according to their governance practices in 937 partnerships established during 2016-2018. The findings showed that the organizations had strongly implemented the phases of building and scoping and managing and maintaining, while their governance practices regarding phases of reviewing and revising and sustaining outcomes ranged between moderate and low levels. The results also revealed significant differences between the overall implementation of the partnering life cycle practices and the NPO's year of establishment. It was concluded that analyzing the current situation of implementing the best practices of partnership governance is useful to explore the efficiency and effectiveness of partnerships between NPOs and other actors, as well as the existing policy gaps, so as to create and implement sustainable-oriented partnerships.

RESUMO

The sustainability of organic agriculture is associated with the farmers' experience, quality of information provided, management of risks, and compliance with legislation. The objectives of this study were to identify the sources used by the organic farmers to gain information related to organic production, and to assess organic farmers' perceived attitudes towards extension services. To address the research objectives, in-depth semi-structured interviews were conducted with 10 organic farmers in central Pennsylvania. The interviews were digitally recorded and transcribed verbatim, categorized and coded, then thematically analyzed using an interpretive description methodology. The results showed that the extension services were not identified as a primary source of information that was frequently used by the organic farmers. Other organic farmers and organizationa for organic agriculture were the two primary sources of informaiton. The organic farmers were very adept at building social capital in seeking informaiton to address their issues and problems. The primary challenges faced by the organic farmers were the control of insects and weeds, and weather-related issues. The results highlighted that in addition to identifying viable information sources, factors such as adaptive capacities to climate change and certification were key to successful production in organic systems. The present study provides rich and deep information on how farmers perceive organic agriculture and extension services. The outcome of the research undertaken will enable planners, policy makers and the related Cooperative Extension personnel to better understand perceptions of the farmers to devise viable and workable policies and plans that address the concerns and challenges of the farmers.

RESUMO

Assessing farmers' satisfaction with the quality of agricultural-extension services is essential for developing extension programs that comply with farmers' needs and agroecological conditions. This study aimed to determine factors influencing farmers' satisfaction with extension services. Data were collected through a questionnaire from a random sample of 393 farmers in the Kafr El Sheikh governorate. Farmers assessed the quality of extension services by five main indicators: (1) availability, (2) accessibility, (3) diversity, (4) relevance, and (5) effectiveness. Descriptive statistics and a logistic-regression model were used to analyze the data. Results showed that farmers had lowly participated in the provided extension services. The accessibility of services was ranked first with regard to satisfaction, while diversity of services was the lowest-ranked quality attribute. Results also revealed that factors significantly influencing farmers' satisfaction included farm size, diversity of farming activities, annual income, and participation in extension services. Results provide practical implications for policy makers to support smallholder farmers by providing high-quality extension programs.

RESUMO

The inability of farmers to comply with global good agricultural practices (GlobalGAP) standards has led to food safety issues harmful to human health and sustainable agriculture. This study aimed to assess the extent of GlobalGAP compliance among orange farmers and investigate barriers associated with compliance. Data were collected with structured questionnaires from 238 orange farmers. The findings showed that the farmers' rate of adherence to the GlobalGAP standards was moderate (mean 3.58). Using factor analysis, the following four groups were identified as key barriers to compliance: personal and economic barriers, awareness and information barriers, institutional-support barriers, and infrastructure barriers. Institutional support barriers were deemed most important by farmers in compliance decisions (mean 4.29), followed by personal and economic barriers (mean 3.89). Therefore, a focus on the barriers faced by smallholder farmers would be crucial to improve their adoption of food safety standards. This can enhance the quality of agricultural commodities, customers' safety, and the livelihood of smallholder farmers.

RESUMO

A diverse group of rhizobacteria persists in the rhizospheric soil, on the surface of roots, or in association with rice plants. These bacteria colonize plant root systems, enhance plant growth and crop yield. Indigenous rhizobacteria are known to promote soil health, grain production quality and serve as sustainable bioinoculant. The present study was aimed to isolate, identify and characterize indigenous plant growth promoting (PGP) diazotrophic bacteria associated with the rhizosphere of rice fields from different areas of Jammu and Kashmir, India. A total of 15 bacteria were isolated and evaluated for various PGP traits, antagonistic activity against phytopathogens, production of hydrolytic enzymes and biofilm formation under in-vitro conditions. The majority of the isolated bacteria were Gram-negative. Out of 15 bacterial isolates, nine isolates produced IAA (12.24 ± 2.86 to 250.3 ± 1.15 µg/ml), 6 isolates exhibited phosphate solubilization activity (36.69 ± 1.63 to 312.4 ± 1.15 µg/ml), 7 isolates exhibited rock phosphate solubilization while 5 isolates solubilized zinc (10-18 mm), 7 isolates showed siderophore production, 8 isolates exhibited HCN production, 6 isolates exhibited aminocyclopropane-1-carboxylate (ACC) deaminase activity, 13 isolates exhibited cellulase activity, nine isolates exhibited amylase and lipase activity and six isolates exhibited chitinase activity. In addition, 5 isolates showed amplification with the nifH gene and showed a significant amount of nitrogenase activity in a range of 0.127-4.39 µmol C2H4/mg protein/h. Five isolates viz., IHK-1, IHK-3, IHK-13, IHK-15 and IHK-25 exhibited most PGP attributes and successfully limited the mycelial growth of Rhizoctonia solani and Fusarium oxysporum in-vitro. All the five bacterial isolates were identified based on morphological, biochemical and 16S rDNA gene sequencing study, as Stenotrophomonas maltophilia, Enterobacter sp., Bacillus sp., Ochrobactrum haematophilum and Pseudomonas aeruginosa. Rice plants developed from seeds inoculated with these PGP strains individually had considerably higher germination percentage, seed vigor index and total dry biomass when compared to control. These findings strongly imply that the PGP diazotrophic bacteria identified in this work could be employed as plant growth stimulators in rice.

RESUMO

The Asteraceae (Compositae) family is one of the largest angiosperm families that has a large number of aromatic species. Pulicaria undulata is a well-known medicinal plant that is used in the treatment of various diseases due to its essential oil (EO). The EO of both Saudi and Egyptian ecospecies were extracted via hydrodistillation, and the chemical compounds were identified by GC-MS analysis. The composition of the EOs of Saudi and Egyptian ecospecies, as well as other reported ecospecies, were chemometrically analyzed. Additionally, the phytotoxic activity of the extracted EOs was tested against the weeds Dactyloctenium aegyptium and Bidens pilosa. In total, 80 compounds were identified from both ecospecies, of which 61 were Saudi ecospecies, with a preponderance of ß-pinene, isoshyobunone, 6-epi-shyobunol, α-pinene, and α-terpinolene. However, the Egyptian ecospecies attained a lower number (34 compounds), with spathulenol, hexahydrofarnesyl acetone, α-bisabolol, and τ--cadinol as the main compounds. The chemometric analysis revealed that the studied ecospecies and other reported species were different in their composition. This variation could be attributed to the difference in the environmental and climatic conditions. The EO of the Egyptian ecospecies showed more phytotoxic activity against D. aegyptium and B. pilosa than the Saudi ecospecies. This variation might be ascribed to the difference in their major constituents. Therefore, further study is recommended for the characterization of authentic materials of these compounds as allelochemicals against various weeds, either singular or in combination.

RESUMO

The increasing number of fraudulent pesticides on the market not only constitutes a major threat to sustainable agriculture but can also have adverse consequences for the environment and human health. The purpose of this study is to assess farmers' risk perception with regard to fraudulent pesticides and to establish the determinants of their perception. Data were collected through structured questionnaires from 370 farmers from the eastern region in Saudi Arabia. The findings showed that farmers had a high perception of physical, legal, social, and physiological risks of counterfeit pesticides, while they had a moderate perception of agri-environmental risks (M = 3.47, SD = 0.72) and economic risks (M = 3.52, SD = 1.11). Moreover, 73.5% of farmers reported that they had purchased fraudulent pesticides in the last three years. The results of the t-test revealed that the number of farmers who had purchased fraudulent pesticides was significantly higher than the number of farmers who had not purchased such pesticides regarding the perception of the majority of risks, except for physical risk. Multivariate regression analyses showed that age, farm size, farming experience, extension contact, and purchased fraudulent pesticides were significantly associated with risk perception. The findings suggest that awareness campaigns on recognizing fraudulent pesticides among farmers are needed, as well as policy measures, to combat counterfeiting in the agricultural sector in cooperation with other stakeholders.

RESUMO

The purpose of this study was to investigate the needs of extension agents for training on organic agriculture (OA) in the Riyadh Region. Fifty-five percent (n = 69) of extension agents were selected to collect data through an electronic survey. Results indicated that extension agents in the Riyadh Region cited on job training as a main source for acquiring knowledge in OA. Agents expressed interest in receiving training in OA in general, OA marketing, and transitioning to OA. The most useful resources were field days at organic farms, OA training sessions at colleges, and attending OA trial plots. There were no differences in the level of interest in training; however, there were significant differences between individuals in terms of their experience in OA, job responsibility for providing information related to OA, and area of specialization in their job. This study recommends developing professional training programs based on the current knowledge of extension agents.
