Revitalizing Degraded and Abandoned Lands: Reflections from Local Government Involvement in Mud Brick Production - Tanzania

The study assessed local government involvement in revitalising abandoned holes and degraded lands around brick-making sites in Morogoro Municipality. Specifically, it delineated the effects of mudbrick-making activities on the communities surrounding the brick-making sites, identified alternative uses of the abandoned holes in the brick-making sites, and established the knowledge required by the community and brick-makers for improving abandoned land use for sustainability. Several techniques were utilised in data collection, including interviews and focus group discussions with village and ward leaders, district environmental officers, district community development officers, district planners, mud brick makers, and some members of the community from three specific wards, namely Kauzeni, Mindu, and Kihonda Maghorofani. The findings revealed a significant contribution of the mudbrick-making industry to enhancing income and improving the living standards of communities through employment creation. Particularly, women were involved in selling food to brick makers, while youth actively participated in brick-making activities. The abandoned holes resulting from soil extraction were repurposed for fishing, vegetable cultivation, and sugar cane production. The income accrued from these activities improved housing standards and increased social interaction among people from different regions, including seasonal migrants attracted to brick-making activities. Despite the noted positive effects, mud brick activities contributed significantly to land degradation due to the traditional technologies used in the process, resulting in large holes that posed risks to human and livestock lives. The study recommends enhancing brick makers' and landowners' awareness of implementing mud brick-making activities with appropriate sustainable environmental protection to improve the socio-economic status of both brick makers and the broader community.

The Quantitative Inhibition Effects of Meteorological Drought on Sugarcane Growth Using the Decision Support System for Agrotechnology Transfer-CANEGRO Model in Lai-bin, China

Sugarcane is the most important cash crop for producing sugar and the most promising high-yield bioenergy crop in China. Lai-bin is a major sugarcane growing and karst area in the Guangxi Province of China. However, frequent droughts over the years have caused huge losses on sugarcane production in this region. Therefore, the daily quantitative response mechanisms of sugarcane growth to multiple meteorological drought scenarios were discovered in Lai-bin using the DSSAT−CANEGRO model. The daily Standardized Precipitation Evapotranspiration Index (SPEI) was developed to detect the possible scenarios of meteorological drought events over the sugarcane growth periods. The results indicate that, in general, the inhibitory effect on sugarcane growth is enhanced by the increase in the intensity and duration of meteorological drought, which involved cane yield (CY), stem height (SH), leaf area index (LAI), and evapotranspiration (ET). Additionally, a light drought at the seedling stage and a light, moderate, and severe drought at the maturity stage give a promotion effect on sugarcane growth, but its overall CY increase rate is less than 5%. The stem elongation stage is the most sensitive period of sugarcane growth to all scenarios of meteorological drought, and the CY reduction rates reached 7.12%, 16.48%, 18.80%, and 29.05%, when the plants suffered from light, moderate, severe, and extreme meteorological droughts, respectively. Alternate drought–flood scenarios presented a facilitating or an inhibiting effect on sugarcane growth during different periods, which cannot be ignored. In conclusion, the quantitative function relationships between meteorological drought and sugarcane growth are revealed by this study.

Multistage sugarcane yield prediction using machine learning algorithms

Sugarcane is one of the leading commercial crops grown in India. The prevailing weather during the various crop-growth stages significantly impacts sugarcane productivity and the quality of its juice. The objective of this study was to predict the yield of sugarcane during different growth periods using machine learning techniques viz., random forest (RF), support vector machine (SVM), stepwise multiple linear regression (SMLR) and artificial neural networks (ANN). The performance of different yield forecasting models was assessed based on the coefficient of determination (R2), root mean square error (RMSE), normalized root mean square error (nRMSE) and model efficiency (EF). Among the models, ANN model was able to predict the yield at different growth stages with higher R2 and lower nRMSE during both calibration and validation. The performance of models across the forecasts was ranked based on the model efficiency as ANN > RF > SVM > SMLR. This study demonstrated that the ANN model can be used for reliable yield forecasting of sugarcane at different growth stages.

Kinetic parameters of Lactobacillus acidophilus growth in the lactic fermentation of non-centrifugal cane sugar agroindustry wastes

The use of sugarcane for the production of non-centrifugal cane sugar is one of the main economic activities in some areas of the central region of the state of Veracruz, México, however, this sector faces different social, techno-economic and environmental challenges. One of the most important problems affecting this agribusiness is the lack of adequate management of the waste generated in the process, mainly sugarcane scum (SCS) and mold wash water (MWW). Lactic fermentation is proposed as an alternative for the utilization of these wastes, since this process reduces the concentration of carbohydrates, producing lactic acid (LA) and increasing the nutrient content. An important aspect of the fermentation process is the knowledge of the kinetic parameters, since with these it is possible to carry out the scaling up. In the present work, the lactic fermentation of SCS and MWW was studied using the bacterium Lactobacillus acidophilus and the kinetic parameters were obtained with the Gompertz model and the Logistic model. The physicochemical characterization of the residues was carried out and the parameters of substrate consumption, lactic acid production and cell density were evaluated during fermentation of a 150 g SCS/L solution in a 0.5 L reactor. After 72 h of fermentation, a maximum growth of 7.63 log CFU/mL, a 50.32% carbohydrate consumption, and a maximum production of 7.56 g LA/L were obtained. For the Gompertz model, the parameters obtained were μmax=1.2420 h-1, λ=20.46 h y A=7.585 log CFU/mL, whereas for the Logistic model they were μmax=0.3214 h-1, λ=25.39 h y A=7.584 log CFU/mL. It was observed that both residues promote the development of the microorganism L. acidophilus, however, the kinetic parameters of μmax y λ indicates that it needs more time to adapt to the residues, so it will be necessary to implement strategies to optimize these values.

From feed to fork: immunity, performance and quality of products from farm animals fed sugarcane products

Sugarcane extracts have generated a growing interest due to their potential applications that extend beyond conventional sugar and ethanol production. These by-products, along with sugarcane extracts offer valuable nutrients and compounds that can be utilized in animal feed supplementation, aiming to improve immunity and growth performance, and the quality of animal-derived products consumed by humans. The immune-boosting properties of sugarcane supplementation have been documented through several studies highlighting enhanced cytotoxicity, increased phagocytic capacity, and modulation of immune cells and cytokine production. Abundant in polyphenols and bioactive compounds, sugarcane products are believed to contribute to these immunological effects. However, further research is required to unravel the specific mechanisms underlying these actions. Supplementing sugarcane by-products in animal feed has shown promising results of improved growth rates and weight gains in various animal species. Sugarcane supplementation positively influences animal performance by optimizing nutrient intake and utilization, enhancing feed conversion efficiency, and promoting healthy growth. Moreover, sugarcane supplementation has been associated with improved meat tenderness and overall quality in animal-derived products. To optimize the utilization of sugarcane products, future research will need to focus on determining optimal inclusion quantities and product or extract combinations, identifying specific compound classes, and balancing nutritional profiles in animal feed formulations. Additionally, studies should focus on evaluating long-term effects on animal health and subsequent product quality, and explore the environmental sustainability of sugarcane product supplementation in feed. This mini-review explores the impact of sugarcane product supplementation on swine, poultry, aquaculture species and ruminants, focusing on its effects on immunity, growth performance, and product quality.

The frequency and phenological stage of foliar application of nutrients and biostimulant can increase sugarcane yield and biomass and bioenergy productions

AbstractThe impacts of sugarcane (Saccharum spp.) production include an extensive area of cultivation, high use of technology, and the generation of by‐products that must be utilized. Achieving higher productivity while reducing the expansion of cultivation is challenging. A potential strategy for increasing sugarcane yields and productivity is the foliar application of nutrients and biostimulants at different stages of sugarcane growth. The present study assessed the impact of the foliar application of nutrients (N, B, Cu, and Zn) and a growth regulator as biostimulant (indole butyric acid, gibberellic acid, and kinetin) on sugarcane metabolism, stalk and sugar production, and quality. Field experiments were performed at 17 sites during four growing seasons (2017–2018, 2018–2019, 2019–2020, and 2020–2021) using sugarcane with three harvest times (early, mid‐late, and late harvests). The treatments were as follows: (i) no foliar application of the biostimulant and nutrients (control), (ii) foliar application of the biostimulant and nutrients at the vegetative stage (VS) of sugarcane, (iii) foliar application of the biostimulant and nutrients at the maturation stage (MS) of sugarcane, and (iv) foliar application of the biostimulant and nutrients at both the vegetative and maturation stages (VMS). Foliar application did not increase ribulose 1,5‐bisphosphate carboxylase activity but increased phosphoenolpyruvate carboxylase activity and the activities of the antioxidant enzymes. Peroxidase and catalase activities were higher, >100% and 45%, respectively, in VMS, whereas superoxide dismutase activity increased by 54% in MS compared with control. Consistent with these results, sugarcane had low hydrogen peroxide and malondialdehyde contents in VMS. In addition, the plant biometric parameters were highest in VMS, which sugarcane produced 105, 92, and 86 Mg stalk h−1 in early, mid‐late, and late harvest seasons, respectively. In summary, the foliar application of the biostimulant and nutrients efficiently promoted the growth, productivity, and quality of early, mid‐late, and late harvest seasons. The positive effects of foliar application on the enzymatic and physiological responses of sugarcane can be achieved when applications are performed in both the VMS in all harvest seasons.

Assessment of physio-biochemical assessment and gene expression analysis of sugarcane genotypes under water stress.

Sugarcane, an economically important crop cultivated for its unique character of accumulating sucrose into its stalk and the world's major crop according to production quantity. Sugarcane production is negatively influenced by abiotic stresses because it faces all types of environments due to its long-life cycle period. Among the various abiotic stresses, drought is one of the major limiting factors creates obstacle in sugarcane production. Thus, an attempt was made to assess the molecular insights into sugarcane genotypes under water stress. A preliminary screening was done in ten sugarcane genotypes grown under semi-arid region of India through physiological, biochemical and antioxidant responses of these genotypes under two water deficit levels. In the current study, drought was imposed on ten sugarcane genotypes during their formative stage (110 DAP) by depriving them of irrigation. A pot experiment was carried out to see how several commercial sugarcane genotypes responded to water scarcity. Sugarcane received two treatments, the first after 125days and the second after 140days. The physio-biochemical and antioxidant responses recorded were RWC, MSI, SCMR, Proline accumulation, SOD, Catalase, Peroxidase and Lipid peroxidation. The significant variations were recorded in responses of all genotypes. On the basis of physio-biochemical, three genotypes Cos 98,014, Cos 13,235 and Colk 14,201 were selected for differential gene expression pattern analysis. The total RNA was isolated and reverse transcribe to cDNA and real time PCR was performed for expression analysis under 10 genes. Under drought conditions, all sugarcane genotypes showed significantly decreased RWC, chlorophyll content, and MSI. However, when water was scarce, proline buildup, malondialdehyde (MDA) contents, enzymatic antioxidant activity (CAT, POD, and SOD), and contents all increased dramatically. Finally, in all physiological and biochemical parameters, Co 98,014 genotype displayed superior adaptation responses to drought stress, followed by Co 018, Cos 13,235, and Colk 14,201. For gene expression analysis out of 21 genes, 10 genes were expressed in sugarcane genotypes, in which 7 genes (Shbbx2, Shbbx3, Shbbx4, Shbbx5, Shbbx8, Shbbx15 and Shbbx20) were upregulated and 3 genes (Shbbx1, Shbbx16 and Shbbx17) were downregulated. The statistical analysis conducted in this study demonstrated that drought stress had a negative impact on physiological responses, including RWC, SPAD, and MSI, in sugarcane crops. However, it was found that the crops were able to survive in these stress conditions by increasing their biochemical parameters, all while maintaining their growth and function.

A Comprehensive Analysis of Transcriptomics and Metabolomics Revealed Key Pathways Involved in Saccharum spontaneum Defense against Sporisorium scitamineum.

Sugarcane smut, caused by Sporisorium scitamineum, poses a severe threat to sugarcane production. The genetic basis of sugarcane resistance to S. scitamineum remains elusive. A comparative transcriptomic and metabolomic study was conducted on two wild Saccharum species of S. spontaneum with contrast smut resistance. Following infection, the resistant line exhibited greater down-regulation of genes and metabolites compared to the susceptible line, indicating distinct biological processes. Lignan and lignin biosynthesis and SA signal transduction were activated in the resistant line, while flavonoid biosynthesis and auxin signal transduction were enhanced in the susceptible line. TGA2.2 and ARF14 were identified as playing positive and negative roles, respectively, in plant defense. Exogenous auxin application significantly increased the susceptibility of S. spontaneum to S. scitaminum. This study established the significant switching of defense signaling pathways in contrast-resistant S. spontaneum following S. scitamineum infection, offering a hypothetical model and candidate genes for further research into sugarcane smut disease.

Productivity, water use efficiency and soil properties of sugarcane as influenced by trash mulching and irrigation regimes under different planting systems in sandy loam soils

IntroductionIn the era of climate change, sugarcane used to face a problem associated with water shortage due to erratic rainfall patterns and lowered water tables. Improved water use efficiency using innovative crop management strategy is needed for sustainable sugarcane production. Trash mulching with different irrigation regimes can effectively modify the plant's hydrothermal micro-environment for increasing cane yield and water productivity.MethodsKeeping this in the background, a field experiment was conducted at Sugarcane Research Institute, RPCAU, Pusa, India, from 2016–17 to 2018–19 to investigate the effects of trash mulching and irrigation regimes on sugarcane productivity, water use efficiency (WUE) and soil properties in different planting systems. The field experiment comprised 12 treatments including four planting methods viz. conventional flat planting (CF; 75 cm row spacing) with trash mulching (6 t ha−1), CF planting (75 cm row spacing) without trash mulching (6 t ha−1), paired row trench (PT) planting (30: 120 cm row spacing) with trash mulching (6 t ha−1), PT planting (30: 120 cm row spacing) without trash mulching (6 t ha−1) and three irrigation schedules consisted of irrigation water (IW); cumulative pan evaporation (CPE) ratio of 0.60, 0.80, and 1.00 was laid out in strip plot design with three replications.Results and discussionThe cane yield (103.5 t ha−1) was found significantly higher in PT planting with trash mulching over the CF planting method with or without mulching. Concerning irrigation regimes using the IW/CPE ratio, it was found that the IW/CPE of 0.6 resulted in 16.9, 13.3% higher water-use efficiency, and 37.1, 40.7% higher water productivity over those under IW/CPE of 0.8, and 1.00, respectively. Furthermore, soil parameters like soil microbial biomass carbon (SMBC) and dehydrogenase activity were increased by 12.5, and 17.5 % due to trash mulching with trench planting as compared to those under conventional flat planting without mulching. The results suggest that planting sugarcane in paired rows and irrigation scheduling at 1.00 IW/CPE with the adoption of trash mulching practices is effective for increasing profitability by way of higher sugarcane productivity and water productivity and also in sustaining soil health.

Socio-Environmental Overview of The Main Sugarcane Producing Municipalities in Sergipe Between the Years of 2001 and 2022

Objective: Analysis of the socio-environmental situation of the main sugarcane producing municipalities in the state of Sergipe, in the period between 2001 and 2022. Theoretical Framework: Sugarcane cultivation represents an important economic role for communities and countries that produce this commodity. In this scenario, Brazil emerges as the main sugarcane producer on the planet and, along with the benefits arising from the agro-industrial sugarcane production chain, there are socio-environmental problems arising from the anthropization of the landscape and natural resources allocated in the production of co-products of this culture that need to be reviewed in light of climate emergencies and the demands of different social actors. Method: The research has an exploratory nature, using scientific articles available from Science Direct and Capes Periodical Platform and secondary data collected on the Mapbiomas and Terrabrasilis platforms. Results and conclusions: The results showed the dissonance between the global analysis of environmental degradation indicators, such as fires and deforestation, and the data relating to each municipality analyzed. And it was concluded that there is an urgent need to re-analyze public policies for monitoring and controlling socio-environmental indicators in order to contain the anthropization processes caused by sugarcane cultivation. Implications of the research: This research allows us to clearly understand the socio-environmental dynamics caused by sugarcane cultivation in the main sugarcane producing municipalities of Sergipe, in order to contribute to a realistic debate on the current stage of environmental degradation and on the construction of the near future due to social and environmental demands arising from changes in the climate. Originality/value: No analysis was found on the set of municipalities studied based on the main agricultural crop produced, which implies a scenario of exploration that is not only reflective and political but also open to new work that can be developed in each of these municipalities separately, or together, with the purpose of bringing quality of life and conscious and environmentally appropriate development to the communities in this group of municipalities and to the state of Sergipe.

A ScWIP5 gene confers fall armyworm resistance by reducing digestive enzyme activities in sugarcane.

The fall armyworm, Spodoptera frugiperda, is one of the most dangerous pests to various crops. As the most crucial sugar crop, sugarcane is also constantly threatened by these pests. Plant wound-induced proteinase inhibitors (WIP) are natural defense proteins that play important roles in the defense system against insect attack. Breeding for resistance would be the best way to improve the variety characteristics and productivity of sugarcane. Screening and verification for potential plant endogenous insect-resistant genes would greatly improve the insect-resistant breeding progress of sugarcane. A sugarcane WIP5 gene (ScWIP5) was up-regulated 536 times after insect feeding treatment on previous published transcriptome databases. ScWIP5 was then cloned and its potential role in sugarcane resistance to fall armyworm evaluated by construction of transgenic Nicotiana benthamiana. The toxicity of ScWIP5 transgenic N. benthamiana to fall armyworm showed lower weight gain and higher mortality compared to wild-type N. benthamiana feeding group. Furthermore, the concentration of JA and NbAOC, NbAOS, and NbLOX from the Jasmin acid biosynthesis pathway was significantly induced in ScWIP5 transgenic N. benthamiana compared to the control. In addition, digestive enzyme actives from the insect gut were also evaluated, and trypsin and cathepsin were significantly lower in insects fed with ScWIP5 transgenic N. benthamiana. These results indicate that ScWIP5 might enhance insect resistance by increasing JA signal transduction processes and reducing insect digestive enzyme activities, thus impacting insect growth and development. © 2023 Society of Chemical Industry.

Use of sugarcane crop residue silage with different levels of inclusion in dual-purpose cow diets

In the sugar cane production chain, different byproducts are generated that can be used in animal feed. Their conservation in the form of silage is an important contribution towards improving animal production in tropical regions. The objective was to evaluate the inclusion of different levels of silage from sugarcane crop residues in the diet of dairy cows in a family farming system. Nine lactating cows were used in a 3x3 Latin square design in triplicate and means were compared using the Tukey test. The treatment sequences were randomly assigned with periods of 14 days. Three treatments were formulated that included feed of mixed native grasses, supplemented with sugarcane top silage with different inclusion levels (2 kg/DM for T1, 4 kg/DM for T2 and 6 kg/DM for T3), along with commercial concentrate and corn silage. Milk production, its chemical composition, and the efficiency of feed utilization were evaluated. The average milk production, fat content and crude protein were, respectively, 9.38kg/cow/day, 32.6 and 340.0 g/cow/day. No differences were detected (P>0.05) for any of the variables evaluated, but the inclusion of 6 kg of sugarcane residues silage improved the animals' feed efficiency. Therefore, sugarcane top silage is a viable alternative for feeding ruminants.

Evaluation of the profitability and competitiveness of sugarcane production in Ivory Coast using Pearson and Monke's Policy Analysis Matrix (1987)

In Ivory Coast, sugarcane production is one of the main income-generating activities in rural areas. In recent years, the sugar sector has been booming due to strong demand on the national and international markets. This study therefore aims to assess the profitability and competitiveness of the Ivorian sugar sector. Primary and secondary data have been analysed using Pearson and Monke's (1987) Policy Analysis Matrix (PAM). The results show that the production link in the sugarcane chain is financially and economically profitable. It is also competitive and has a comparative advantage, despite the distortions. However, producers are poorly protected. Agricultural policy measures aimed at increasing yields per hectare and improving incomes would therefore be beneficial for sugarcane growers.

Transcriptomic Analysis Reveals Candidate Genes in Response to Sorghum Mosaic Virus and Salicylic Acid in Sugarcane.

Sorghum mosaic virus (SrMV) is one of the most prevalent viruses deteriorating sugarcane production. Salicylic acid (SA) plays an essential role in the defense mechanism of plants and its exogenous application has been observed to induce the resistance against biotic and abiotic stressors. In this study, we set out to investigate the mechanism by which sorghum mosaic virus (SrMV) infected sugarcane responds to SA treatment in two sugarcane cultivars, i.e., ROC22 and Xuezhe. Notably, significantly low viral populations were observed at different time points (except for 28 d in ROC22) in response to post-SA application in both cultivars as compared to control based on qPCR data. Furthermore, the lowest number of population size in Xuezhe (20 copies/µL) and ROC22 (95 copies/µL) was observed in response to 1 mM exogenous SA application. A total of 2999 DEGs were identified, of which 731 and 2268 DEGs were up- and down-regulated, respectively. Moreover, a total of 806 DEGs were annotated to GO enrichment categories: 348 biological processes, 280 molecular functions, and 178 cellular components. GO functional categorization revealed that DEGs were mainly enriched in metabolic processes, extracellular regions, and glucosyltransferase activity, while KEGG annotation revealed that DEGs were mainly concentrated in phenylpropanoid biosynthesis and plant-pathogen interaction suggesting the involvement of these pathways in SA-induced disease resistance of sugarcane in response to SrMV infection. The RNA-seq dataset and qRT-PCR assay showed that the transcript levels of PR1a, PR1b, PR1c, NPR1a, NPR1b, PAL, ICS, and ABA were significantly up-regulated in response to SA treatment under SrMV infection, indicating their positive involvement in stress endorsement. Overall, this research characterized sugarcane transcriptome during SrMV infection and shed light on further interaction of plant-pathogen under exogenous application of SA treatment.
