Introduction: Saltwater intrusion poses a serious risk to global food security. As a soil amendment, biochar mitigates the negative effects of saltwater intrusion in rice, yet the beneficial effects on agricultural productivity with different exposure times and salt concentrations have not been fully examined.

Methods: A pot experiment was conducted to investigate the effects of 30% (w/w) rice husk biochar on the growth, ion accumulation, and yield of the Phitsanulok 2 rice cultivar under salt stress due to saltwater intrusion. Rice plants were grown in saline soil amended with biochar and were salinized with 6, 8, and 10 dS/m saltwater for 1, 2, and 3 months. A treatment without biochar was taken as the control.

Results: The results showed that biochar amendment significantly increased the survival, shoot height, and tiller numbers of rice treated with the 6-10 dS/m saltwater for 1 and 2 months, as well as the treatment with 6 dS/m salt water for 3 months, in comparison with the control. The grain yield was about 40 g/pot for rice with biochar treated for 1 month with 6-10 dS/m saltwater and for the rice treated for 2 months with 6 dS/m. The results indicated that biochar application could alleviate the intrusion of high-salinity water for 1 month of salt exposure, and it could alleviate the intrusion of medium-salinity water for 2 months.

Conclusion: Therefore, a 30% (w/w) rice husk biochar amendment is a reliable strategy for mitigating the risks of saltwater intrusion for the growth and productivity of rice.

Background: Distillery vinasse is one of the promising bio-fertilizers, as it contains significant amounts of essential chemical elements, allied with sorghum that is widely used in the diet of ruminant animals and has been considered as an alternative to the production of other cereals or forages. This study aimed to evaluate saccharin sorghum silage from fertilization with vinasse.

Methods: The research was conducted using the BRS-511, CR-1339, and CR-1342 genotypes. The silage was held for 170 days after sowing, with experimental design in blocks with triple factorial (genotypes x fertilization x inoculation) totaling 54 installments. At 95 days, the silos were opened for sample collection and analysis bromatological analysis.

Results: The results indicate the primary source of variation was genotype, characterizing them with different potentials in productivity and better results for BRS-511, CR-1339, and CR-1342. The bromatological results indicate good quality for CR-1339 and CR-1342 hybrids, however, better digestability for BRS-511. There was no observable difference between the factors of fertilization. The inoculation additive assists in the reduction of lignin appears to be high. PCA analysis showed differences between cultivars (BRS-511, CR-1339, and CR-1342) and fertilization. However, the PCAs showed the genotypes show similar results with conventional fertilization and sugarcane vinasse.

Conclusion: The study reflected the possibility of producing sweet sorghum silage with soil sugarcane vinasse fertilization as fertilizer.

Introduction: Lycium barbarum L., commonly known as red goji berry, is a widely recognized plant-based medicinal herb with nutritional and therapeutic properties. In this study, the effects of various cytokinins on the germination of L. barbarum seeds and the growth of seedlings were investigated under in vitro conditions.

Methods: The berries were first surface sterilized and dissected, and the seeds were then cultured on Murashige and Skoog (MS) medium supplemented with different concentrations (0.5, 1.0, and 1.5 mg/L) of 6-benzylaminopurine (BAP), thidiazuron (TDZ), and kinetin (KIN) for 10 weeks at 25±2ºC with a photoperiod of 16 hours and a light intensity of 1000 lux. Upon observation after 10 weeks of culture, all cytokinin-treated cultures produced 100% seed germination as early as 7 days. KIN at 0.5 mg/L produced plantlets with the greatest height (8.40 ± 0.97 cm) with extensive rooting and the greatest total chlorophyll production. Besides, KIN at 1.5 mg/L resulted in the highest number of leaves per plantlet (6.90 ± 0.72), while 1.0 mg/L of TDZ led to the greatest biomass, i.e., fresh weight (FW) of 0.328 ± 0.05 gram and dry weight (DW) of 0.023 ± 0.003 gram.

Results: All cytokinins used in this experiment (BAP, TDZ, and KIN) promoted different in vitro growth promotion responses in L. barbarum. The effects of different types and concentrations of cytokinin on the height of plantlets, number of leaves per plantlet, fresh and dry weight, the extent of rooting, and the chlorophyll content were demonstrated to be statistically significant.

Conclusion: This study provides valuable insights into optimizing in vitro cultivation techniques for goji berry propagation, which could contribute to developing superior cultivars and increased production of this superfruit in the future. For future perspectives, extended research in elucidating the underlying mechanism associated with cytokinin supplementation is imperative in understanding the roles of cytokinins and optimizing their effects on plant growth promotion.

Excessive consumption of ultra-processed foods (UPF) is a global health concern associated with an increased incidence of non-communicable diseases. UPF are characterized by their extensive industrial processing and high content of additives, preservatives, chemicals, and artificial ingredients that are used to mask defects or inferior ingredients of end food products, presenting a multifaceted challenge to contemporary society. Exposure assessment showed that almost 50% to 30% of the energy consumption per day comes from UPF. The more processed a food is, the less likely it is to be healthy and nutritious. UPF affect human health by increasing the risk of obesity, heart disease, cancer, depression, diabetes, etc., as these foods are typically made up of a large number of preservatives, high content of fats, sodium, and sugars, and low contents of protein, fiber, and potassium. The ingredients required for the production of UPF are commonly derived from intensive monoculture and livestock of raw foods. This, in turn, exerts imminent effects on agriculture, biodiversity, and the global food system by altering the bioavailability of nutrients within agricultural soil, thereby increasing the dependency on fertilizers and insecticides. Recent studies have shown that over-consumption of UPF has an effect on culinary traditions, loss of biodiversity, human well-being, and food system sustainability. Therefore, for better food system sustainability, the consumption of UPF should be reduced, and we should move toward minimal processing technologies, preferably for seasonal and organic local products. Based on available data, there is an urgent need to implement policies and regulations for the agro-food industry to include nutritional and environmental criteria. This review explains the different dimensions of UPF in relation to health, nutrition, environment, current challenges, future innovations, and wider sustainability concerns.

Introduction: Colorectal cancer is a complex condition influenced by genetic mutations and environmental factors. Due to its intricate nature, the diagnosis and treatment of this condition require a comprehensive approach that considers individual circumstances. The study aimed to identify genes linked with colorectal cancer and their therapeutic agents from natural bioactive compounds.

Methods: The significantly prognostic differentially expressed genes (DEGs) were screened out from NCBI Gene Expression Omnibus (GEO) datasets. A protein-protein interaction network was constructed using STRING Database, and key genes were identified using Network Analyzer and CytoNCA plugins within Cytoscape. Further analysis involved functional annotations, and biological pathways analysis, SRC mechanism to uncover the role of SRC in CRC. Additionally, we performed virtual screening and molecular docking, Physiochemical property analysis along with MD simulation study to propose suitable natural compounds for promising therapeutic targets.

Results: The study conducted differential gene expression analysis, identifying 3621 statistically significant genes, with 1467 upregulated and 2154 downregulated. The top ten genes with the highest degree, betweenness centrality, and closeness centrality in the PPI network were selected as key genes. The SRC gene was found to have the highest degree and closeness centrality. Functional annotation and pathway analysis of key genes with a specific focus on the SRC mechanism revealed that the SRC's role in activating the RAS-RAF-MEK-ERK and Wnt/β-catenin pathways in CRC cells, promoting proliferation and invasion. Molecular modelling of SRC led to the screening of phytocompounds from tropical fruits, with Rutin exhibiting a higher docking score compared to FDAapproved anticancer drugs. MD simulations over 100 ns and the post-MD analysis i.e. RMSD, SASA, RMSF, FEL, RG, Hydrogen bond, PCA, and MMPBSA, comprehended the stable and robust interactions of a protein-ligand complex. These findings suggest Rutin's potential as a potent natural molecule for treating CRC.

Conclusion: The study concludes that SRC plays a pivotal role in CRC, influencing cellular processes critical to cancer development and Rutin has been found to be a promising SRC inhibitor, suggesting a potential alternative therapeutic strategy for CRC. The consistent molecular interactions of Rutin necessitate further validation through wet lab experiments, offering hope for individuals affected by CRC.

Green Revolution aims to boost food production and feed millions of Indians, but it also has negative effects on agriculture and society's health. Natural manures like cow dung and cow urine can counteract the adverse effects of inorganic fertilizer on soil along with improving physicochemical qualities, maintaining the soil quality, and increasing crop output. Zero Budget Natural Farming (ZBNF) formulations like Jivamrit promote soil health and microbial activities and are an excellent source of macronutrients, other micronutrients needed for plant growth, plus adds beneficial microbes, nitrogen (N2), phosphorus (P), potassium (K), and natural carbon (C). Further, conventional agricultural methods, like monocropping and heavy tillage, can damage soil bacteria which contributes to sustainable agriculture through nitrogen fixation, siderophore synthesis and nutrient absorption. A sustainable agricultural system is resource-efficient, socially and commercially competitive, ecologically sound, and supportive of society. Jivamrit, a natural organic manure, is gaining interest due to concerns about the sustainability of input-intensive agriculture systems. It promotes crop growth, quality, and yield, enhances soil pH, population, and activity of beneficial microorganisms, and helps with nitrogen fixation, phosphate solubilization, and easy decomposition. Long-term use of Jivamrit, may disrupt soil microbial balance, may leading to overpopulation of certain species. The current review on the Jivamrit emphasizes on the biological and chemical characterization and its significance to the agriculture.

Background: Rapid industrialization has polluted waterways, threatened aquatic ecosystems and endangered human health. To solve this problem, sustainable industrial practices and innovative water treatment technology must be implemented to ensure clean and safe water for future generations.

Methods: This study aimed to investigate the adsorbent capacity of Cocos nucifera husk for ineffective removal of methylene blue (MB), a cationic dye abundantly found in industrial effluent. Adsorption capacity is measured using parameters such as dye elimination percentage and polymer dosage. The Langmuir and Freundlich isotherms, adsorption kinetics (pseudo-first, pseudo-second, and second order), and intraparticle diffusion were determined to better understand the adsorption process.

Results: The increased dosage of cellulose fiber results in the availability of a greater number of adsorption sites and an increased surface area. However, the dye removal efficacy decreased after reaching a specific dosage of 0.6 g/L. A concentration of 0.05 g/L was most effective in eliminating Methylene blue (MB). The value of the separation factor (0.99) suggested a favorable adsorption isotherm. The reciprocal of the heterogeneity factor (-1.469) demonstrated the concentration-independent adsorption behavior of Fiber. Freundlich and Langmuir's isotherm model showed that the pseudo-second-order kinetic model demonstrated the highest level of correlation with the experimental data about the mechanism of adsorption. The Methylene blue (MB) adsorption is not limited by the intraparticle diffusion and adsorption is influenced by surface area and concentration variation of fiber as well as solvent concentration, as evidenced by low R2 value and the fact that the intraparticle diffusion plot does not intersect with the origin.

Conclusion: The study concludes that Cocos nucifera husk can be effectively used for the treatment of wastewater.

Background: Amla (Emblica officinalis) is one of the most prominent fruits in terms of nutritional and medicinal properties and is utilized for the preparation of many traditional processed foods and in Ayurvedic formulations.

Objective: This study aims to investigate the enzyme activity and physical and chemical quality parameters during the growth and development stages of amla fruit for the determination of proper harvesting time to get optimum nutrient contents of fruit.

Methods: The amla fruits of the chakaiya variety were harvested at 135 to 270 days after fruit set (DAFS) in 2021 and 2022 to study the various physical, chemical and enzymatic changes during growth and maturation.

Results: The geometrical and gravimetric attributes of the fruit, viz. diameter, height, weight, volume, surface area, sphericity, aspect ratio, and radius of curvature increased. However, density decreased with the growth and maturation of the fruit. Furthermore, the rolling resistance, yellowness index and firmness of the fruit increased during the entire harvesting period of 135 to 270 DAFS. Total soluble solids and titratable acidity of the fruits increased only up to 195 DAFS and after that, continuously decreased. In contrast, ascorbic acid concentration grew in the entire growth and development period. Tannin, phenolic compounds and naringin content of the fruit steadily dropped until the final stage of harvest. Pectin Methyl Esterase (PME) activity was detected very low, 0.009 unit/ml at 135 DAFS, but as the fruit grew and matured, activity increased to 0.307 unit/ml at 270 DAFS. Polygalactouronase (PG) activity was not detected until 210 DAFS and, therefore significantly increased with maturity.

Conclusion: Considering the optimal value of all studied physical, chemical and enzymatic attributes of the fruit during the entire harvesting period of 135 to 270 DAFS, the optimal harvesting time of the fruit was 210 DAFS.
