Abstract

Sustainable agriculture in arid and semi-arid regions faces unique challenges that require targeted assessment and intervention. Addressing the knowledge gap in this context, the current study evaluates the sustainability performance of 50 rainfed farms in the Zaër Region of northwestern Morocco using the innovative Indicateurs de Durabilité des Exploitations Agricoles/IDEA method (indicators of farming systems sustainability), which encompasses agro-ecological, social and economic criteria to assess the three pillars of sustainability. Customized assessment criteria and a tailored scoring system, specific to the region’s context, are employed, resulting in a comprehensive grid with 18 indicators across nine components. Data analysis and visualization were facilitated using statistical methods and an Excel macro. The findings reveal limitations in the sustainability of the surveyed farms. Socio-territorial factors, including issues with product quality, insufficient farmer training, limited workforce mobilization and low social involvement, contribute to the overall sustainability challenges. Agroecologically, low crop diversification, inadequate space management, and excessive reliance on chemical inputs are identified as areas of concern. On the economic scale, low specialization levels hinder economic viability despite some financial autonomy. The study emphasizes the need for interventions to enhance sustainability in rainfed agrosystems. Recommendations are provided to address socio-territorial constraints, improve agricultural practices, and promote economic viability. The findings have implications for policymakers, farmers and stakeholders, offering valuable insights for prioritizing strategies and actions to achieve sustainable agriculture in arid and semi-arid regions.

Abstract

Anthracnose caused by Colletotrichum gloeosporioides is a prevalent disease that poses a significant threat to shallot production in Indonesia. To mitigate this issue, the use of biological agents presents an alternative for disease control, reducing the inherent risks associated with the use of chemical pesticides. Therefore, this study aimed to determine the potentiality and mechanism of the biological agents (Rhizophagus intraradices and Bacillus thuringiensis) combined with silica. These agents were evaluated both individually and in combination to suppress the development of anthracnose in Tajuk variety shallot. The study was conducted in the laboratory and greenhouse, arranged in a completely randomized design with six treatments and three replications. The ability to suppress pathogenic fungi was determined based on in vitro antagonism tests of B. thuringiensis, disease severity, area under disease progress curve (AUDPC), plant height, number of leaves, number of tillers and the percentage of mycorrhizal fungal infections. Furthermore, the mycorrhizal infection on plant roots was observed using staining methods. The results showed that the Bt BMKP isolate was included in the B. thuringiensis strain RC9 group with the capacity to inhibit C. gloeosporioides in vitro by 18.88%. The combination treatment of R. intraradices, B. thuringiensis and silica reduced infection from anthracnose by 15.52% compared with control. These three treatments also significantly increased the agronomic performance of shallot up to six weeks after planting compared to control and other treatments.

Abstract

Impatiens hawkeri x platypetala rooted cuttings are typically cultivated using rice husks as a substrate. However, due to the poor water-holding capacity of this medium, Impatiens grows slowly in this environment. A viable alternative is the cocopeat perlite mixture which has a better water-holding capacity compared to the rice husk. Currently, there is no sufficient information available regarding the best growth medium to improve the quality of I. hawkeri x platypetala rooted cuttings in Indonesia. Therefore, this study aimed to obtain the best medium for quality rooted cuttings I. hawkeri x platypetala. The method employed was a randomized complete block design with two factors. The first factor was the Impatiens varieties consisting of Impala Agrihorti, Imadata Agrihorti, and Lavender, while the second was the growth medium, comprised of four levels namely rice husk (control), as well as a mixture of cocopeat with 3%, 5% and 8% perlite. The result showed that there was no interaction between varieties and growth medium. The mixture of 3% perlite in cocopeat exhibited better outcomes compared to other treatments. This medium increased the number and length of roots, stem diameter, plant height, leaves thickness, leaves number and survival rate. Therefore, the addition of 3% perlite in cocopeat could replace the rice husk as a rooted cutting growth medium for I. hawkeri x platypetala.

Abstract

Mount Merapi, one of Indonesia’s most active and dangerous volcanoes, experienced a devastating eruption in 2010, causing numerous fatalities and widespread damage to homes and land, especially in areas vulnerable to the volcano’s activity. Despite the inherent risks, many farmers continue to cultivate the region’s land. This study examines the resilience of farmers in the Mount Merapi area in light of the persistent volcanic activity. Employing a qualitative methodology, including in-depth interviews and field observations, the research reveals that farmers’ resilience is shaped by their individual experiences and the contributions of government, private sector, and community actors. Long-term residence in the area has equipped farmers with the knowledge and confidence required to navigate the risks and hazards associated with the volcano. Farmers prioritize their safety but also focus on safeguarding their livestock and other essential resources, which are integral to their livelihoods. The local community is instrumental in supporting farmers and residents in disaster-prone zones, while external organizations offer additional advantages to farmers’ lives. The study proposes that a collaborative effort among all stakeholders is essential for maintaining farmers’ livelihoods in areas susceptible to volcanic activity.

Abstract

The livestock subsector especially broiler production plays a significant role in the livelihood and food security in Ghana. Several researchers in developing nations have employed value chain methodologies to investigate the linkages and the interactions of the various actors in the poultry sector. However, none of these studies comprehensively captured each actor’s strengths, weaknesses, opportunities and threats, as well as the governance structure and profitability of the broiler industry. This paper fills this gap by analyzing the governance structure, value addition, determinants of profitability and prospect of the broiler industry using 290 respondents (180 broiler producers, 65 distributors and 45 retailers) from the Greater Accra, Ashanti and Bono Regions of Ghana. The study adopted the scoring analytical technique, net farm income (NFI), the modified Cobb-Douglas function and the SWOT (strengths, weaknesses, opportunities, threats) matrix for the analyses. The results revealed producers as the key governors with the highest value addition and return on investment. Distributors and processors on the other hand form informal cartels to monopolize their activities to increase bargaining power. Whilst credit access, education, business training, age and feed type influenced profitability, the broiler industry is threatened by high importation of frozen chicken, high taxes, lack of capital access and high cost of operation. The study recommends that the government should pursue measures to minimize the cost of operations through input-tax exemptions and reduce the importation of chicken products. Stakeholders should invest in input supply, processing technologies and transportation facilities to boost local production for profit gains.

Abstract

Winged bean is a remarkable climbing plant, distinguished by its multiple segments that serve as growth sites for shoot, leaf and flower. Several studies have shown that the plant requires shoot pruning to increase the production of its flower buds, pods and seeds, but this practice can inhibit the generative phase. To overcome this challenge, the application of additional fertilizer is needed to provide the required nutrients. Therefore, this study aims to determine the effects of shoot pruning and additional fertilizer on the growth, yield and bioactive compounds of winged bean seeds. The determination of the proper rates of fertilization was important for plant production and to support sustainable agriculture. The study procedures were carried out at IPB experimental station in Leuwikopo, IPB University, Bogor. A Randomized complete block design (RCBD) was utilized with two factors and three replications, namely leaf pruning (without shoot pruning, 15 cm, and 30 cm from the ground) and additional fertilizer (0, 6.25, 12.5 and 18.5 g NPK 16-16-16 plant-1). The parameters observed included plant height, leaf nutrient, root length, yield, leaf number, as well as protein and fatty acid profile of seeds. The results showed that shoot pruning treatment and additional fertilizer had no interaction effect on plant growth and seed yield. Shoot pruning caused an increase in leaf number, fatty acid and linoleic acid content by 17% to 20%, 10%, and 16% to 19%, respectively, compared to the control. The use of additional fertilizer at a concentration of 6.25 to 12.5 g NPK (16-16-16) plant-1 increased leaf number, nutrients, and seed yield. Based on the findings, the highest seed yield (2.56 tons ha-1) was achieved with the application of additional fertilizer at the rates of 6.25 g NPK (16-16-16) plant-1, but shoot pruning was not required.
