The invasions of Argemone mexicana in sub–Saharan Africa’s natural habitats negatively affect biological diversity. We investigated A. mexicana’s suppressive effects on Phaseolus vulgaris seed germination (petri dish experiments) and seedling growth (pot experiments). Phaseolus vulgaris seeds and seedlings were treated with different A. mexicana leaf (AmL) and root (AmR) crude extract concentrations to study their suppressive effects on the test plant. The results revealed that AmL and AmR crude extract suppressed P. vulgaris seed germination and seedling growth, particularly at higher concentrations (70% and 100%). At these concentrations, the seed germination inhibition percentage was twice that at lower concentrations (25% and 50%). The number of seeds that germinated at higher concentrations was lower compared to those that germinated at lower concentrations. Correspondingly, seed germination was delayed at higher concentrations compared to lower ones and controls. Moreover, P. vulgaris seedling growth vigour was negatively affected as the growth parameters (fresh biomass, root lengths, stem diameters, and heights) under 75% and 100% concentrations of AmL and AmR were lower. Though this study’s findings revealed that A. mexicana crude extract reduced P. vulgaris germination and growth, further research is required to investigate the allelopathic effects of A. mexicana on other plant species.

Home gardens are recognised globally and can address the challenges of food insecurity and malnutrition. However, climate change, infertile soil, reduction in freshwater supply and increasing demand for food, coupled with crisis pandemics, put further strain on food systems and society. The authors focused on a desktop review to understand the principles of home gardens and consolidate the suggestions provided in the literature to determine possible strategies for resilience and continuation of home gardens post-COVID-19 to ensure sustainability within rural households and communities within South Africa. Besides enhancing the food supply within each household, home gardens can improve family health, women empowerment, and possible individual economic benefits by selling excess food, which, in the bigger scope, contributes to the self-efficiency and sustainability of households and communities. The global pandemic has reinforced the strain on the societal issues within South Africa, namely unemployment, food supply and hunger. Recommendations from the literature reveal practical approaches towards educational material to better transfer skills amongst generations, provide better-quality seeds and promote the growth of nutrient-dense foods, such as indigenous foods.

This study aims to isolate and recognize (native/indigenous) hydrocarbon degrading fungal strains from oil-laden soils, at different geographical locations in KRI oilfields, Iraq. The identification was mainly based on macroscopic and microscopic examinations, but due to morphological similarities, which make the identification at species level doubtful in some cases, an attempt was made to use molecular techniques as well, as confirmatory/comparative analysis. The extracted DNA from hypha was used for polymerase chain reaction (PCR) amplification, using specific internal transcribed spacer primer (ITS1/ITS2). PCR product sequencing analyses were compared with the other related sequences in GenBank (NCBI) for molecular evolutionary analyses. Results showed that; out of 68 screened fungal strains; only two genera (i.e. Aspergillus spp. and Penicillium sp.) were identified as the most potent hydrocarbon degrading fungi. DNA sequence analysis confirmed the validity of the species as; Aspergillus fumigatus-KU321562.1; A. flavus-MH270609.1; A. niger-MK452260.1 and Penicillium chrysogenum-MK696383.1.

A higher level of variability can be found in Nepalese foxtail millet. To assess potential traits for further breeding activities and estimate the genetic diversity, phenotypic and genotypic coefficient of variation, heritability, genetic advance, and correlation coefficient for 15 different genotypes of foxtail millet, an experiment was conducted in alpha lattice design with 3 replications at Agronomy farm of IAAS, Lamjung, Nepal during March- June 2021. The analysis of variance revealed highly significant differences among the accessions for all the traits observed indicating the presence of a sufficient amount of variability. The value of the Shannon index ranged from 0.245 (plant anthocyanin coloration of the basal sheath) to 1.309(grain color) which indicates that the characters were more diverse for grain color while the value of evenness ranged from 0.22 (plant: anthocyanin coloration of the basal sheath) to 0.965(panicle density) indicating that the characters are more evenly distributed for the intensity of green leaf foliage. High PCV, high GCV, high heritability, and high genetic advance per mean were found for flag leaf length, peduncle length, no. of nodes, and yield per hectare. It indicates that these traits are less influenced by the environment and hence can be exploited by pure line and mass selection methods for crop improvement. Yield per hectare was positively and significantly correlated with grain per panicle (r=0.4**) and no. of nodes (r=0.39**). A strong positive correlation was observed between plant height and the number of nodes, flag leaf width, panicle length, and flag leaf length indicating their consideration for further breeding activities. The findings of the study can be crucial in identifying better-performing genotypes that can help develop improved varieties

Cotton, known as the “monarch of fibers” for meeting global textile demands, faces a decline in production due to natural threats like the cotton jassid insect. In Bangladesh, where this insect has caused production losses of 20% to 50%, government support for upland cotton cultivation is challenged. Two experiments at BSMRAU’s entomological field in 2021-2022 aimed to address this issue. The first confirmed the presence of the jassid through molecular analysis, while the second studied how different cotton varieties responded to biopesticides. Three different treatment combinations using different dosages of biorational insecticides on CB-12 and CB-14 cotton varieties were implied to see the interactions for revealing the biopesticidal effects on species cotton cultivars. The study identified the cotton jassid insect by analyzing its mitochondrial DNA, targeting cytochrome oxidase subunit-1 gene. The resulting nucleotide sequences were assigned accession numbers ranging from OR362770 to OR362772. A phylogenetic analysis further confirmed the insect’s identity as the cotton jassid, with strong support indicated by a 94% bootstrap value. This study delves into the impact of various treatments and different cotton plant varieties on chlorophyll and anthocyanin levels in parts of plants infested by the jassid. Principal component analysis (PCA) demonstrated the significant role of two environmentally-friendly insecticides in controlling the cotton jassid across two distinct cotton varieties. Notably, there were significant differences observed in chlorophyll and anthocyanin levels among the treatments and cotton varieties. Variety CB-12 consistently exhibited higher levels of chlorophyll and anthocyanin, suggesting it may possess a greater resilience to pests. These findings underscore the importance of selecting appropriate cotton varieties and employing effective treatment strategies to manage jassid infestations and enhance crop productivity. This research provides valuable insights for the promotion of sustainable cotton cultivation for supporting textile industry in Bangladesh.

Ten plant powders were tested at 2% on five legume seeds for their entomocidal effects against Callosobruchus maculatus. A completely randomized design (CRD) with five pairs of freshly emerged adult bruchids was used to treat 40g of disinfected legume seed types with 2g of the selected plant powders. An analysis of variance was performed on the data on the percentage of oviposition deterrence, hatchability, pest tolerance, and weight loss. Zanthoxylum zanthoxyloides (87.02%) P. guineense (77.36%) and E. aromatica (73%) significantly deterred oviposition. The maximum percentage egg hatched was recorded in G. max (94.71%) and significantly lower on C. cajan with P. guineense (2.33). Ife Brown (20.83%) recorded significantly lowest tolerance compared to M. pruriens (99.17%). Percentage weight loss was significantly reduced in G. max irrespective of treatment and M. pruriens suffer no weight loss. Incorporation of Z. zanthoxyloides, P. guineense and E. aromatica powder proved to be promising biopesticide.

Kasisi Agricultural Training Centre (KATC) in association with small-scale farmers, has a vital role in fostering sustainable organic practices for sustainable agricultural development. A study was conducted to establish the alignment of sustainable agriculture practices at KATC, with that of the National agricultural policy and, how sustainable practices are implemented by the training institution. The qualitative case study involved seventeen (17) participants who were purposively selected from the target population. Data was collected using semi-structured interviews, observations, and a focus group discussion. A document review on SNAP’s sustainable agricultural practices (SAPs) was conducted, and data were analysed using thematic content analysis. The study showed that KATC’s sustainable organic practices such as soil fertility management, soil and water conservation, and pest and disease management were aligned with policy objectives of, increasing crop production, food security, and nutrition, promoting sustainable management and use of natural resources. An integrated approach is essential in implementing SAPs aligned with policy objectives, to enable the effective adoption of SAPs by small-scale farmers and agricultural development. The study recommended specific policies and legislation on sustainable agriculture to influence the implementation of sustainability practices.

Studies conducted regarding goods and services exhibit a low willingness to pay (WTP) in developing countries. However, many scholars found that this may not be the preference for the good but the result of the choice of payment vehicle. Thus, low WTP for ecosystem conservation may not indicate a low welfare for the ecosystem service. There’s the argument that the choice of the payment vehicles may be needed to obtain exact welfare estimates where there is imperfect substitutability between money and labor. Otherwise, there might occur underestimating of the welfare benefit of ecosystem services. Thus, the ultimate objective of this study is to investigate the labor-as a payment-vehicle by using a CV method and estimating the factors influencing pastoralists’ decision to contribute labor for the rangeland improvement. This study demonstrates it through a rural pastoralists’ choice to elicit their willingness to contribute a labor for the rangeland improvement in Yabello District, southern Ethiopia. A total of 228 sample respondents were selected randomly from the two adjacent Kebeles. Logit model was used to identify the factors that influence pastoralists’ willingness to contribute the labor for the rangeland improvement. The result shows that the endowment of household’s active labor highly influence respondents’ willingness to contribute. In addition to that, variables like sex, age, dominant livelihood activities, livestock holding, perception towards the rangeland improvement, dependency ratio, and initial bid value were significantly influence pastoralists’ willingness to contribute the labor for the rangeland improvement. To sum up, the findings of this study suggest that, just like the monetary value, the labor value can also be used to evaluate the demand of community for the ecosystem services improvement. Thus, employing the labor as a means of payment vehicle for accurate welfare estimations might be a practical alternative, and also giving a chance for the respondents to indicate their willingness to contribute for rehabilitation of degraded ecosystem in developing countries.

Four Bangladeshi villages were chosen at random to represent a total of 64 home gardens.The study’s objective was to evaluate the variety of tree species and the carbon store in the tree biomass on Char Island, both above and below groun. The Shannon Wiener index was used to evaluate the variety of tree species, and allometric equations were used to estimate the carbon stock, with the assumption that the stock represented 50% of the carbon in the tree biomass. The findings indicated that home garden ecosystems could store an average of 18.00 Mg of carbon per hectare, ranging from 1.66 Mg of carbon per hectare to 58.93 Mg per hectare and tree species diversity ranged from 0 to 1.84 with a mean value of 1.05 where most abundant was Eucalyptus camaldulensis (44.21%) which stored the most C (33.62Mg ha-1) followed by Moringa oleifera (29.37 Mg ha-1) in tree biomass. The study provides a evidence of tree diversity and carbon storage in char island.

The purpose of this study was to examine the climate and non-climatic inputs influencing barley yield in Ethiopia. The study employed an augmented Cobb-Douglas production functional approach to model factors influencing barley yield. The results revealed that short-season rainfall and temperature variables showed a positive relationship with barley yield, having minimal impact on barley yield. Conversely, long-season rainfall showed negative impact on barley yield, mainly due to extreme rain events such as high rainfall above optimum requirement of the crop as well as scarcity of rainfall in some pocket areas. The result infers that cultivation of barley moderately depends on rainfall. Subsequently, irrigated land, fertilizer and barley seed quantities used exhibited positive impact on barley yield. Fertilizer and barley seed inputs demonstrated positively significant influence on barley yield, implying that barley yield is highly responsive to application of fertilizer and barley seed inputs and moderately responsive to irrigation input.
