Abstract

A study on the diversity and ethnobotanical uses of medicinal plants was conducted in Zana and Laelay Koraro Woredas, in Northwestern Tigray, Ethiopia, in December 2023. The study used ethnobotanical techniques like informant consensus, field observations, semi-structured interviews, ranking and both purposive and stratified sampling methods. In both woredas, a total of 117 medicinal plant species were identified, representing 53 families and 93 genera. The Fabaceae (11.11%), Solanaceae (6.8%), and Euphorbiaceae (4.3%) families were the most commonly used medicinal plants. The most prevalent growth forms were shrubs (35%), trees (33%), and herbs (26%). With 37.6% of the plant, leaves were the most commonly used part, followed by roots (22.8%) and seeds (8.7%). Internal application accounted for 61% of herbal preparations, with 39% of the remainder being used externally. Acaia Lehai is the most endangered medicinal plant, primarily due to agricultural expansion. Lepidium sativum is the preferred remedy for treating febrile illnesses. The study revealed a strong and significant positive correlation between the age of healers and their familiarity with medicinal plants (p < 0.01, r = 0.7) and a weak negative correlation between knowledge of these plants and educational attainment. According to the study, the availability of plant-based medications and their link to medical knowledge have been crucial in maintaining a wide variety of medicinal plant species. Patchy forests are essential hotspots for these plants, providing important information for pharmacological and phytochemical research as well as useful resources for healers. To promote conservation and sustainable forest management, it is essential to ensure that future generations respect and continue to utilize traditional medicine. Educating the use of medicinal plants and how local elders treated for youths are fundamental for the development of modern medicine and pharmacological results.

Abstract

To achieve sustainable development for the world’s population food security is one of the environmental existential challenges that must be addressed. This study examined the trend in agricultural land use change, in Lagos Metropolis between 1984 and 2024. Data used included Landsat 5 Thematic Mapper (TM) image of 1984, Landsat 8 Operational Land Imager (OLI) image of 2013 and Landsat 9 (OLI) of 2024. The satellite images were processed using ArcGIS 10.5 and IDRISI Selva software. The processed images were classified using a combination of Normalized Difference Vegetation Indices (NDVI), visual interpretation and Maximum Likelihood Classification algorithm. An inventory of the extent of land use/land cover for each year and the rate of change were determined, the pattern of conversion of urban farmlands to other land uses was also examined, using the Land Use Change Modeller of the IDRISI software. Findings from the study indicated that farmlands in the study area declined by 13.03% between 1984 and 2013 and by 21.79% between 2013 and 2024. So also between 1984 and 2013 as much as 89.48% of farmlands were converted to other land uses, while only 10.52% remained unchanged and between 2013 and 2024 as much as 73.51% had been converted to other land uses, while 26.49 % remained unchanged. Furthermore, the NDVI results indicated a deterioration in the environmental condition of the urban farmlands. The study concluded that the present status of urban farming in Lagos Metropolis has far reaching implications for food security that needed to be addressed.

Abstract

This study investigates the effects of organic liquid fertilizers and inorganic fertilizers on tomato yield in the Central Rift Valley of Ethiopia, addressing the significant yield gap between Ethiopian tomato production. Results indicate that the application of combination of 100% recommended nitrogen and phosphorus with either 60 ha⁻¹ and 45L ha⁻¹ organic liquid fertilizer significantly increased tomato marketable and total yields at all locations, with the highest yield observed at Sankura (50.36 t ha-1), Hawassa (46.6 t ha-1) and Koka (36.7 t ha-1). However, as the inorganic nitrogen-phosphorus application decreased below 100% can decline tomato yields at all sites. From an economic standpoint, applying 100% RNP without OLF yielded the best marginal rate of return (MRR). Additionally, the combination of 100% RNP with 60 L ha⁻¹ of OLF not only demonstrated substantial yield advantages but also proved to be profitable. Based on financial considerations, the sole application of 100% RNP and its integration with 60 L ha⁻¹ OLF best show a higher yield than the rest of the treatments. Therefore, the findings suggest that both approaches are recommended for optimizing tomato production in the central Rift Valley of Ethiopia, with the choice depending on farmers’ financial capacity and long-term soil health considerations.

Abstract

The study focused on Analyzing yield performance of farmers’ and improved varieties of a selected genotype of bread wheat (Triticum aestivum L.).The research was conducted in the Bale Zone, Goro Woreda, Oromia Region, Ethiopia.Testing was conducted on sixteen bread wheat varieties, comprising eight farmers' varieties and eight improved variants. During the 2021/22 season, these genotypes were cultivated at the Goro Community Seed Bank using a Randomized Complete Block Design. The analysis of variance revealed significant differences among the genotypes for most traits at the individual level. The majority of traits exhibited a significant (p≤0.05) variety and genotype-by-environment (G×E) interaction. The mean grain yield of the varieties, ranging from 6.67 to 4 tons per hectare, showed considerable variation. Phenotypic coefficient of variation (PCV) exceeded the genotypic coefficient of variation (GCV) for most traits. PCV varied from 2.6% (kernel number per spike) to 36.2% (grain yield), while GCV ranged from 2.23% (kernel number per spike) to 29.9% (grain yield). The heritability estimates for plant height (95.7%) and spike length (91.1%) were both above 80%, indicating a high degree of genetic influence. When considering the percentage of mean, the expected genetic improvement ranged from 0.95% for spike length to 49.14% for grain yield. Positive and negative genotypic and phenotypic relationships were also identified among the yield components. Among the varieties, Tikur Goshmber had the highest grain yield at 33.34kunt/hect, while Tate had the lowest at 11.6 kunt/hect. The improved varieties Kekeba and Digalu had the highest and lowest yields at 39.01 kunt/hect and 10.01 kunt/hect, respectively. It has been observed that the genotypes being studied demonstrate have significant variability, heritability, and correlations among the traits examined that consequently for the advancement of bread wheat yield in the respective area.

Abstract

Women-owned agribusinesses in Gauteng, South Africa face significant challenges in leveraging Industry 4.0 technologies for sustainable growth to understand the influence on business expansion and profitability to design targeted interventions.This study examines the impact of Industry 4.0 on women-owned agribusinesses in Gauteng, South Africa, using a survey of 135 female farmers to identify key factors and strategies for growth. A survey was distributed through Google Forms to gather quantitative data from 135 female farmers. Descriptive and inferential statistics, including Spearman's rank correlation and ordinal regression, were used to analyse the data. The study found that women-owned agribusinesses face significant financial challenges, with 48.1% reporting losses or no profit in 2022 compared to 2018. Only 9.6% of businesses reported gross profits above R200,000, indicating that very few women-owned agribusinesses were able to reach high profitability levels. The study also found that funding, market accessibility, and agricultural skills are the three most important factors for business expansion, with 73.3% of participants considering funding extremely important. Additionally, the study found a weak positive correlation between the use of Industry 4.0 technology and gross profit margins, suggesting that technology adoption is important but not the primary driver of profitability. Women-owned agribusinesses in Gauteng face significant financial difficulties, with a majority reporting losses or low profitability. Tailored interventions considering demographic factors and leveraging the potential of technology are needed for sustainable growth. The study provides valuable insights into the challenges and opportunities faced by women-owned agribusinesses to navigate the impact of Industry 4.0. The findings highlight the importance of focused support in areas like funding, market access, and skill development to improve the expansion and sustainability of these businesses.

Abstract

This study investigates the impact of plant growth-promoting fungi (PGPF) on the growth, yield, and nutrient uptake of tef (Eragrostis tef). We evaluated the effects of three fungal species—Trichoderma harzianum Rifai BGB, Penicillium italicum Wehmer, and Aspergillus v. Tiegham BGB on various growth and yield parameters, including plant height, panicle size, shoot and root dry weight, and grain yield per plant. Additionally, we assessed their influence on the nutrient content of tef grains, specifically nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca), zinc (Zn), and iron (Fe). Results showed that Trichoderma harzianum Rifai BGB and Penicillium italicum Wehmer significantly (P<0.001) enhanced plant height, panicle size, and the number of fertile tillers compared to the control and Aspergillus. Both fungi also significantly increased shoot and root dry weight, as well as grain yield per plant. Regarding nutrient uptake, Trichoderma and Penicillium markedly improved nitrogen, phosphorus, magnesium, calcium, zinc, and iron content in the grains. Penicillium showed notable improvements in these nutrients compared to the control and Aspergillus, while Trichoderma was superior in nitrogen content. Our findings suggest that Trichoderma harzianum Rifai BGB and Penicillium italicum Wehmer are effective in promoting tef growth, enhancing yield, and improving grain nutritional quality. These results indicate the potential of using these fungi as biofertilizers to optimize tef cultivation and address nutrient deficiencies in tef grains

Abstract

To attain national sugar self-sufficiency by 2030, the Indonesian government has issued Presidential Regulation No. 40/2023 stipulating acceleration of sugar self-sufficiency and supplies of bioethanol as a biofuel. This paper discusses strategies and practical programs to increase productivity as mandated by the Presidential Regulation, using literature reviews and a gap analysis on secondary data obtained from four demo-plots involving plantation companies and farmers. With a land size ranging from 4.4 to 8.4 hectares, each demo-plot applied bongkar ratoon (replacing ratoon with plant cane) and other key components of sugarcane's Good Agricultural Practices (GAP). They include plant variety and maturity recomposition, correct and timely doses of fertilization and water management. The results show that bongkar ratoon and GAP raise productivity from around 5 tons of sugar/hectare to 8.73 - 20.14 tons of sugar/hectare. While the results show promising potentials, expanding the demo-plots into large scale plantations is not straightforward, requiring comprehensive strategies, programs and action plans, some of which are outlined in this paper for both Holding Perkebunan Nusantara's smallholder- and own-plantations.
