Abstract

Red-picking is the key to good coffee quality and is essential for increasing farmers’ income, added value, competitiveness, and development. Knowledge-sharing is one solution to improve the knowledge confidence of farmers and the reach of dissemination of red-picking practices. This research aims to determine the diversity of knowledge-sharing behavior related to red-picking practices according to farmers’ socio-economic status. This research was conducted in a constructivist paradigm with a qualitative approach and case study strategy. According to specific characteristics, seven primary informants were determined by staged, purposive, and peer group discussions. Temanggung coffee stakeholders take part as supporting informants. Interviews, focus group discussions, social media and document observations, expert discussions, peer group discussions, literature reviews, and documentation were used to collect research data. The data were analyzed qualitatively using the NVivo 12 Plus. Research has found that diversity of knowledge-sharing tends to encourage red-picking practices. The research findings also stated that group farmers with an area of land ≤ 1 ha, younger generation group farmers, group farmers with roles as gathering traders, and group farmers who use social media have more diverse knowledge-sharing behaviors. The practice of red-picking can be encouraged by supporting farmers in carrying out knowledge-sharing activities with other farmers with different characteristics. This study implies that the resulting findings will enrich the concept of knowledge-sharing by describing how people utilize social and offline media in sharing knowledge to encourage red-picking practices.

Abstract

Black rice (Oryza sativa L. var. Jeliteng), known for its health benefits compared to white rice, faces challenges in productivity. Among varieties, this black rice is popular in Indonesia but shows low yield. Research on improving black rice through genetic manipulation with antimitotic substances is limited. Therefore, this study aims to compare the effects of colchicine and Bio-catharantin on the germination rate, DNA relative content, and stomatal structure of O. sativa L. var. Jeliteng. Seeds were treated with colchicine (0.1%, 0.2%, and 0.3%) and Bio-catharantin (0.1%, 0.2%, 0.3%, 0.4%, and 0.5%) at soaking durations of 12, 24, and 48 hours. Germination was assayed, ploidy was determined using flow cytometry, and stomatal traits, including size and density, were examined microscopically. The results showed that Bio-catharantin did not exhibit any toxic effects on germination rates, whereas colchicine reduced germination starting at 0.2% concentration. Both chemical agents modified the DNA relative content of Jeliteng black rice. Colchicine generally increased stomatal length and width while decreasing stomatal density, with significant changes at 0.3% concentration for 24 hours. Bio-catharantin also altered stomatal traits, enhancing length and width in most cases but significantly reducing density under certain conditions. Bio-catharantin emerged as a promising alternative to colchicine for inducing chromosomal mutations in plants, offering benefits in altered stomatal structures without the toxic effects on germination, compared to colchicine.

Abstract

This study portrays the roles of Traditional Ecological Knowledge (TEK) in the mitigation of natural hazards. Menoreh Hill in Kulon Progo experienced more than 200 landslides in 2022 and its communities implemented TEK to mitigate them. Hence, this research quantitatively analyzes the role of agriculture-related TEK, especially those applied in hilly areas, to support household resilience to natural hazards. Authors surveyed 106 farm households and interviewed eight key informants in Banjararum and Sidoharjo Villages, Kalibawang and Samigaluh Sub-districts, Kulon Progo Regency, D.I. Yogyakarta. The data were then analyzed using descriptive statistics and binary logistic regression. The descriptive statistics showed that farmers in both villages are highest in practicing alley cropping and integrated farming, while also applying mixed cropping, multiple cropping and locally based planting schedule (pranata mangsa). From binary logistic regression, authors found that TEK practices of multiple cropping, alley cropping and pranata mangsa support farm household resilience to natural hazards, especially landslides. The TEK practices serve as sources of buffer and adaptation capacity in the development of farm household resilience. Interestingly, mixed cropping and membership in farmer groups tend to weaken resilience, as mixed cropping often complicates the recovery efforts in the farmlands, and farmers’ groups are not conditioned to act promptly during hazards or disasters. While TEK has been proven to take roles in the mitigation and adaptation to natural hazards, there is a need to integrate scientific knowledge to improve its optimum benefits.

Abstract

The assessment of nutrient potential is crucial for enhancing tea production and achieving sustainable agricultural goals. Thus, the present study was carried out to assess and map the soil nutrient potential for tea plants through laboratory and geostatistical methods. A total of 74 random soil samples with 3 replications were collected from 0 to 9 cm (topsoil) and 9 to 18 cm (subsoil) depths from Oodaleah Tea Garden (OTG) which belongs to Fatikchhari Upazila of Chattogram District in Bangladesh. All the laboratory analyses were done following standard procedures and maps of individual soil indices were prepared through the Inverse Distance Weighted (IDW) interpolation technique using ArcGIS 10.7 software. The integration of maps for nutrient potential was performed following the Analytic Hierarchy Process (AHP). The mean concentrations of organic matter (OM), total nitrogen (TN), available phosphorus (AvP), available potassium (AvK), and available calcium (AvCa) were found higher at 0 to 9 cm compared to 9 to 18 cm soil depth with significant (p < 0.05) difference among the sampling sites. The maps of individual soil parameters revealed distinct spatial differences at 0 to 9 cm and 9 to 18 cm soil depths. The total study area covered 5.99 km2. Integrated nutrient potential mapping showed that moderately suitable (44.15%) accounted for the largest proportion, followed by highly suitable (26.03%), generally suitable (21.67%), marginally suitable (7.06%), and unsuitable area (1.08%) of the tea plantation suitability evaluation. The integrated map of nutrient potential will aid in better management of the tea soils.

Abstract

Wheat (Triticum aestivum L.), a vital cereal, faces significant challenges from common root rot and spot blotch diseases caused by Bipolaris sorokiniana. This study aimed to explore the potential of plant growth promoting rhizobacteria (PGPR) to enhance wheat growth, reduce fertilizer input, and combat Bipolaris diseases. Two PGPR isolates, selected for their superior antagonistic properties, were identified as Stenotrophomonas koreensis RB11 and Bacillus amyloliquefaciens RB12. These PGPR strains displayed multiple plant growth promoting and biocontrol attributes, including phosphate solubilization, indole-3-acetic acid production, nitrogen fixation and antagonism against B. sorokiniana and other fungi. Wheat seed priming with the PGPR significantly improved germination, plant growth, nutrient content and biomass carbon accumulation in the rhizosphere soil. Importantly, the application of RB11 and RB12 allowed for a 25% and 50% reduction in nitrogen fertilizer usage, respectively, without compromising the yield. RB11 and RB12 also demonstrated potent inhibitory effects on B. sorokiniana conidial germination and significantly controlled common root rot and spot blotch in wheat, similar to those observed with the fungicide Protaf 250EC. Overall, this study underscores the multifaceted roles of S. koreensis RB11 and B. amyloliquefaciens RB12 in promoting wheat growth, reducing fertilizer inputs and effectively suppressing wheat pathogens. These findings contribute to the development of PGPR-based strategies for sustainable crop production and disease control.

Abstract

The current food crisis has become a serious threat to humanity. Other issues such as climate change, farmer regeneration, and excessive use of chemical inputs at the producer level threaten sustainability in agriculture. The sustainability of agricultural practices among farmers remains questionable due to the small number of organic farmers in Indonesia. The purpose of this study was to determine the level of sustainability of rice cultivation and the factors that influence the sustainability of rice cultivation in various types of cultivation in Yogyakarta. Research on farm sustainability that is analyzed in a multidimensional (5 dimensions) and compares 3 types of cultivation has not been widely carried out in Indonesia. This research was conducted in Bantul and Sleman with 90 respondents. The analysis method used Multidimensional Scaling-RAPFISH and Tobit regression. The results showed interesting findings where the 3 types of rice cultivation are in the sufficient (moderately sustainable) category even though the 3 have differences in the use of inputs, especially in the ecological dimension. The factors of education, frequency of attending extension and activity in farmer groups, the use of good agricultural practices, land ownership, and type of cultivation had a positive effect on increasing the sustainability of rice cultivation in various types of cultivation in Yogyakarta. The results of this research have an impact on agricultural extension field education provided by the government to increase the sustainability of rice cultivation in Yogyakarta. It is recommended that the 3 types of rice farmers to pay more attention to the use of Good Agricultural Practices (GAP) to increase sustainability.

Abstract

The application of pectinase in industries will continue to be developed. To broaden the applicability of enzyme manufacturing in new industries, more research to investigate pectinolytic microorganisms with high activity and stability is still required. Therefore, this study aimed to obtain pectinolytic fungi that have the potential as pectinase producers. Pectinolytic fungi were isolated from rotten apple peels and selected based on clear zone formation on pectic agar media after cetyl trimethyl ammonium bromide (CTAB) staining. Pectinolytic fungi were identified based on 18S rRNA partial gene sequences and morphological characteristics. Pectinase production used Mandels and Weber medium with citrus pectin 20 g l-1 addition. Pectinase activity was determined based on the measurement of reducing sugars by a colorimetric method. A total of 5 fungal isolates were successfully isolated. All of the isolates had pectinolytic activities with clear zone diameters ranging between 0.99 to 7.32 mm. The isolate A3 showing the highest pectinolytic activity was identified as Rhizopus stolonifer. Microscopically, R. stolonifer A3 showed typical characteristics for Rhizopus, characterized by the presence of rhizoids, stolons and sporangiophores bearing a single spherical sporangium. The pectinase production of R. stolonifer A3 was optimum at initial pH 5.0, temperature 35 °C and incubation period of 3 days with pectinase activity of 14.75 U ml-1. R. stolonifer A3 produced acidic pectinase having optimum activity at pH 5.0 and temperature 50 °C. Thus R. stolonifer A3 has the potential to be used as a producer of acidic pectinase appropriate for use in the processing of fruit products.

Abstract

Globally, rural women farmers benefited from only 5% of agricultural extension information, and also only 10% of the agricultural extension facilities, this affects their engagement in agricultural development resulting in an increased rate of poverty and lack of the necessary knowledge of agricultural practice. This study aimed to determine the internal and external factors influencing rural women farmers’ participation in agricultural activities in rural areas of Malaysia. The study was conducted in Ranau, Sabah, Malaysia. A sample size of 248 rural women farmers was selected using simple random sampling. A five-point Likert scale questionnaire was used for data collection. Collected data were subjected to descriptive and factor analysis using Statistical Packages for Social Science (SPSS) version 26. The findings indicated that the factors affecting rural women’s participation in agricultural activities in Ranau, Sabah, encompassed access to financial and agricultural inputs, social culture, land rights, access to land, technology adoption, participation in farm management decisions, limited scope of agricultural policy and access to resource and support for women in agriculture. The present study has provided insights into the factors contributing to women’s participation in agriculture activities. The study suggests that a theoretical model should be proposed to test the relationship between these factors and women’s participation in agriculture, along with research to identify solutions for reducing identified barriers.

Abstract

Silver nanoparticles (AgNPs) have various benefits for application in the agricultural sector, such as nano-seed priming to enhance seedling growth and development. In this research, the effectiveness of AgNPs sizes and concentration to enhance Zea mays seeds germination has been investigated. The AgNPs were synthesized using various concentrations of tannic acid (0.025, 0.25, and 5 mM) to produce AgNPs with different sizes to know their optimum size and concentration. The synthesized AgNPs were characterized using a UV-Vis spectrophotometer to determine the absorption spectrum of AgNPs within 400 to 500 nm. Besides that, a transmission electron microscope (TEM) was used to determine the size and shape of the AgNPs, and an atomic absorption spectrophotometer was used to determine the concentration. The results show AgNPs with sizes of 13.39±2.40, 27.25±4.09, and 46.7±10.75 nm, respectively. Subsequently, AgNPs with concentrations of ~8, ~16, and ~24 mg l-1 were exposed to Z. mays seeds for 24 hours, then germinated for 14 days. The results revealed that AgNPs with a size of ~27 nm and a concentration of ~24 mg l-1 showed the highest germination rate and growth despite the control and other treatments. This indicates that the AgNPs with those properties have the potential as a seed nano-priming agent.

Abstract

Worldwide, it has been recorded extensively that plants are subjected to severe abiotic and biotic stressors. The scientific research community has widely reported that multi-abiotic stressors cause horticultural crop losses, accounting for at least 50 to 70% of the crop yield and quality losses. Therefore, this review focused on the detrimental effects caused by abiotic stress factors occurring in single-, combined- and multi-cell stresses on horticultural plants worldwide, along with the best production systems practices for mitigation during and post-single and combined abiotic or multi-stress damages. A conclusion and recommendation could be reached using the pool of research material, which constituted research articles, reviews, book chapters, thesis, research short communications and industrial short communications from at least twenty-five years ago. Findings showed that some of the leading abiotic stresses are single- and combined abiotic stressors like water deficit, salinity, soil pH, phosphate deficiency, wounding, soil density and pot size. Established commercial and smallholder farmers are globally adapting to plant growth regulators and biostimulants as part of their production systems. However, as much as the effectiveness of biostimulants containing humic acids, algal extracts, plant growth-promoting microorganisms and phytohormones has been reported to promote plant development under multi-stress, only a few studies are focusing on organic phytohormone-based biostimulants on horticultural crops grown under adverse multi stress factoring. In conclusion, the review recommends alternative solutions for emerging South African farmers and growers who cannot afford agricultural insurance options and energy alternatives on the common single- and combined abiotic- or multi-stress-factors.
