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

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

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

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

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

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.
