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.","PeriodicalId":32740,"journal":{"name":"Caraka Tani Journal of Sustainable Agriculture","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136099075","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}

To support its future development, there is a need to obtain essential information on the morphological and nutritional characteristics of these bananas for domestic needs and the tourism market. Therefore, this study aimed to analyze the fruit morphology and nutritional composition of six local Balinese banana cultivars mainly consumed on Bali Island, namely Pisang Mas (AA), Buluh (AAA), Lumut (AAA), Susu (AAB), Raja (ABB) and Kepok (ABB) genomes. The observation of fruit morphology followed the guidelines of the International Plant Genetic Resources Institute method for bananas. The nutritional composition was analyzed using standard methods by measuring the proximate composition, vitamin C and concentrations of minerals K, Ca, Fe and P. Based on the morphological relationship coefficient values, it was discovered that all banana cultivars were closely related. Dessert bananas of Pisang Mas, Buluh, Lumut and Susu shared a close relationship with their ancestor Musa acuminata, which contributed to the ‘A’ genome. Meanwhile, Pisang Raja, which could be employed as a dessert or cooking banana, and Pisang Kepok as a cooking banana, exhibited a closer relationship. Various cultivars showed different nutritional compositions in their fruits. In every 100 g of edible portion, the nutrient values of the six bananas contained high carbohydrates and total energy, abundant vitamin C and K, moderate total fibers and protein, as well as low fat and Fe. Based on the nutritional composition, six Bali banana cultivars were found suitable as valuable ingredients in alleviating food insecurity or as dietary components.","PeriodicalId":32740,"journal":{"name":"Caraka Tani Journal of Sustainable Agriculture","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136099074","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}

This research aimed to determine the composition of the carbon fraction, nitrogen fraction and soil carbon stock in different land cover. There were six types of land cover with vegetations of 10-year-old bamboo, 30-year-old bamboo, 50-year-old bamboo, bulrush, a mixture of brushwood and bulrush, and a mixture of Albizia falcataria and brushwood, each of which was sampled three times. Soil samples were used to determine microbial biomass, particulate organic, humic acid, fulvic acid and soil carbon stock. The six land cover types showed significant differences in all fractions and soil carbon stocks. Fifty-year-old bamboo vegetation has the highest carbon storage of 0.029 g g-1 soil. The stable carbon fraction, in the form of humic acid and fulvic acid, in 50-year-old bamboo vegetation is more excellent than that in other vegetation. This study shows that 50-year-old bamboo vegetation has the potential to sequester carbon and store carbon in forms that decompose slowly, namely humic acid and fulvic acid, in the soil for a longer period.","PeriodicalId":32740,"journal":{"name":"Caraka Tani Journal of Sustainable Agriculture","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136377595","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}

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.","PeriodicalId":32740,"journal":{"name":"Caraka Tani Journal of Sustainable Agriculture","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136377593","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}

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.

This study used a nested design with three replications. The factors tested were the shade level (0%, 25%, 50% and 75%) and the genotype of hybrid corn. The results showed that most of the hybrid corn genotypes tested showed an increase in production at 25% shade, while at 50% and 75% shade, they showed a decrease in production. Based on relative production at 25% shade, the genotypes can be split into three groups: sensitive, moderate and tolerant. The tolerant genotype including F1 T8-2A x SM12-2 (G6); Exotic (G13); Talenta (G15); Golden boy (G16); F1 SM12-2 x T9-2 (G20) provided the highest increase in morpho-physiological characters and yields compared to the moderate and sensitive. In all genotype groups, morphological variables (number of leaves, leaf area, stem diameter and relative growth rate), physiological variables (stomata conductance, photosynthetic rate, and total dissolved solids (TDS)), and yield variables (length, diameter, number, weight and unhusked weight of ears) were significantly higher in the no-shade than in the shaded conditions.

Field measurements of N2O fluxes were conducted in agricultural fields growing corn, peanuts, and cassava in Bogor Regency, West Java Province, as well as in peatland areas with Acacia plantations and natural primary forests in Bengkalis Regency, Riau Province. The study assesses the total N2O fluxes for each crop and land type, revealing significant variations in N2O emissions among different crops and land uses. Peatland areas exhibit higher emissions compared to mineral soils, emphasizing the need for targeted mitigation measures in these ecosystems. The findings highlight the importance of considering the type and age of land use when evaluating N2O emissions. Land management practices, such as fertilizer use and soil disturbance, emerge as critical factors affecting N2O emissions.

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.","PeriodicalId":32740,"journal":{"name":"Caraka Tani Journal of Sustainable Agriculture","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135164698","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}
