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.

Abstract

Excessive use of chemical fertilizers leads to serious environmental and health issues, while organic biofertilizers offer a sustainable solution. Jakaba or “jamur keberuntungan abadi,” a local liquid organic fertilizer derived from fungi, is increasingly used by Indonesian farmers. However, its taxonomy and potential applications require further investigation. Moreover, the effects of jakaba on Fusarium and its impact on maize growth remain unexplored. This study aims to characterize jakaba comprehensively, evaluate its anti-Fusarium properties, conduct pathogenicity tests, and assess its effects on maize growth. Morphological analysis of fresh jakaba fruiting bodies was conducted, and molecular identification was performed based on the internal transcribed spacer (ITS) 1/4 regions. The antagonistic test was done using plant pathogenic fungi (Fusarium sp.). In addition, jakaba was evaluated for its impact on the vegetative growth of maize. Observations identified jakaba as belonging to the genus Corallomycetella, characterized by coral-shaped fruiting bodies with an orange hue and a white tip. The hyphae are septate, spore hyaline, and ellipsoid. The Basic Local Alignment Search Tool (BLAST) analysis revealed that jakaba was Corallomycetella repens, with a query cover of 99% and a phylogenetic tree 96% bootstrap (BS) value. Jakaba exhibits antibiosis activity against Fusarium sp., with an inhibition rate of 5.64%. Although C. repens has been previously identified as a cause of root rot in Indonesia, the current study reveals that jakaba is not pathogenic to maize. Furthermore, the application of jakaba’s liquid organic fertilizer at a concentration of 40 ml l-1 significantly increased plant height, leaf length, leaf width, and stem diameter compared to other treatments. These findings highlight jakaba potential as a biofertilizer.

Abstract

Indonesia is one of the largest palm oil producers in the world. The palm oil industry must look at the market competition map, starting from competing countries and other export opportunities to absorb palm oil products to increase state revenues. This paper analyzes the new challenges and opportunities for Crude Palm Oil (CPO) in Indonesia in international trade. Analytical tools were Revealed Comparative Advantage (RCA), Revealed Symmetric Comparative Advantage (RSCA), Dynamic Product Export and X-model Potential Export. The results showed that Indonesian and Malaysian palm oil commodities obtained an RCA value of more than 1 and an RSCA value of close to 1. Indonesia is more competitive than Malaysia. The X-model showed that Indonesian CPO market share optimism is only in India and the rest is less potent. Malaysian CPO market share also has less potential. Therefore, Indonesia’s new challenges are export tariffs, obstructed access, insufficient downstream production and a black campaign. The opportunity for participation in the CPO export market is only in India compared to Malaysia, which has less potential. The two countries have less potential in destinations such as the Netherlands, USA, China and Kenya. Indonesia can take external policies by establishing cooperation with export destination countries, such as trade agreements, so that information about Indonesian palm oil is well received. Meanwhile, internal policies strengthen domestic downstream industry policies, such as the food, health, and renewable energy industries, to strengthen the domestic economy and improve the welfare of Indonesian palm oil farmers.

Abstract

Salinity is considered the most critical environmental factor which negatively affects the germination and growth of plants. In this study, the potential of using Dead Sea water (DS) as a seed priming agent for the mitigation of the adverse effects of salinity on seed germination and growth performance of wheat (Triticum aestivum L.) was investigated. Germination of wheat seeds primed with different doses of DS; 0%, 5%, 10%, 15%, and 20% were evaluated under different saline conditions (0, 100, 200, and 300 mM NaCl). High salinity (300 mM NaCl) remarkably inhibited germination attributes and reduced seedling length. However, seeds primed with DS exhibited improved germination parameters and seedling growth. Among the different DS concentrations used, the 10% DS priming achieved the highest increase in final germination percentage tolerance, germination index, relative germination salt tolerance, and seedling length. The increased tolerance to salinity was associated with improved water imbibition, α-amylase activity, antioxidant capacity and osmotic homeostasis correlated with high proline and soluble sugar levels. In addition, DS priming increased the membrane stability index, and reduced malondialdehyde content and K+ leakage besides lowering Na+/K+ ratio. Overall, priming with DS could be a promising strategy for minimizing the damaging effects of salinity in wheat.

Abstract

Sustainable agriculture offers new hope in overcoming the challenges of the decreasing interest of the younger generation in the agricultural sector. Millennial farmers, as part of this younger generation, are the key to successfully implementing sustainable agricultural development. This study aims to explore the influence of the role of parents, friends, extension workers, and media exposure on the entrepreneurial behavior of millennial farmers, and to explore the influence of entrepreneurial behavior on the financial performance of millennial farmers. The research was conducted in the Special Region of Yogyakarta, Indonesia, which was the first province to inaugurate 1,000 millennial farmers. The research sample consisted of 200 millennial farmers, selected using a simple random sampling method. The analysis employed Partial Least Square Structural Equation Modeling (PLS-SEM). The results reveal that the role of parents does not significantly influence millennial farmers’ entrepreneurial behavior. The role of friends, agricultural extension workers, and media exposure significantly influence millennial farmers’ entrepreneurial behavior. Friends provide motivation, support, and share information. Agricultural extension workers offer knowledge transfer, technology, and programs from the government. Media exposure contributes by providing knowledge and shaping perceptions and behavior. Entrepreneurial behavior has a positive and significant influence on financial performance. The research results impact millennial farmers’ regional commissariat/farmer groups, the extension services by agricultural extension workers, and the media for millennial farmers. It is recommended that policies be implemented to strengthen the role of the regional commissariat of millennial farmers/farmer groups, improve extension services, and develop media relevant to millennial farmers.
