Because the traits were quantitatively inherited, they are affected by changes in location and year. A RBD with three replications was used to identify superior and stable high-zinc rice genotypes in Uttar Pradesh, India. Grain zinc content (GZC) is negatively correlated with grain yield using genetic association study. There was a significant G × E interaction (GEI) and V16 and V21 for GYP and V9, V2 and V10 for GZC were identified as stable based on the AMMI model and bi-plot. V11, V5, V21 for grain yield per plant (GYP) and for GZC, V14, and V10 are found to be stable and common in all AMMI stability parameters. V6, V13 and V5 for GYP and V10, V8 and V2 for GZC were identified as stable based on the mean vs. WAASB bi-plot. V21 for GYP and V4 for GZC was the highest yielder and widely adaptable based on WAASBY scores. V13 for GYP and V1 for GZC were all-time winners. V13 and V1 have the highest predicted mean for GYP and GZC, respectively, based on BLUP. V6, V21and V13 were identified as stable and selected based on the multi-trait stability index (MTSI). These selected genotypes selected through BLUP-based stability methods, MTSI, and strength and weakness plots make it easier to evaluate and select genotypes for varietal recommendations and future Zn-fortified rice breeding studies.

Many raw vegetables, such as salads, are consumed, and consuming raw vegetables contaminated with human and animal feces can lead to a variety of intestinal parasite diseases. The goal of this cross-sectional study was to investigate the incidence of contamination of green leafy vegetables with human intestinal parasites, as well as identify the most common parasite species and any seasonal variation in parasite abundance in green leafy vegetables found and sold for human consumption in various markets and stores in Jeddah. To the best of our knowledge, no research has been conducted on the prevalence of parasite-contaminated vegetables in Jeddah. From September 2020 to July 2021, 250 leafy vegetables (coriander, watercress, lettuce, parsley, leek, and green onion) were collected from various markets and stores in Jeddah. The vegetables were sorted, labelled, and evaluated in the laboratory after being completely washed with distilled water, examined for sediment, staining, and microscopically examined. Chromatographic immunoassay tests were also used to confirm parasite identification. Intestinal parasites were discovered in 35.2% of the vegetables (88/250). Coriander was the most contaminated (64.2%), while green onion was the least contaminated (21.9%). Blastocystis spp. was the most often discovered parasite (55.7%), followed by Strongyloides spp. larva (22.7%) and Entamoeba coli cysts (6.8%). Summer has the greatest percentage of parasites, followed by autumn, while winter has the fewest. There was no statistically significant relationship between the kind of vegetable, seasonal parasite prevalence in green vegetables, and parasite type.These findings highlight the importance of inspecting vegetables grown or imported from endemic countries for parasite contamination. In Jeddah, several fresh green vegetables were tainted with intestinal parasites. This demonstrates that those who consume raw vegetables regularly may be susceptible to parasitic illnesses. These findings highlight the need of monitoring vegetables grown or imported from parasitic-endemic areas. As a result, it is critical to establish strategies and control measures to limit the likelihood of parasites in food-borne diseases.

The research showed that 56.6% of members were willing to pay capital an average of $131 for sustainability of organizations. According to the model results showed that members’ gender, agricultural income, know definition of organization, increase in income of members, pay entry capital, frequency of visiting, meeting the general assembly, cohesion of members positively affected, however, age, household, animal units, negative experience in the past with their organizations negatively affected the members’ willingness to pay capital. In order to sustainable of agricultural organizations, cohesion of members and participation to general assembly must increase. And, encouraging more young and female farmers to become a member, taking an active role cooperatives and unions in marketing and supply input could increase the members’ willingness to pay capital.

Among the findings, it was observed that Quercus ilex's starch granules had the the hightest value of lipid and phosphor content. When observed under scanning electron microscopy, both Quercus ilex and Quercus coccifera starch granules exhibited various shapes such as ovoid, spherical, elliptical and irregular, with diameters ranging from 4 to 25 µm. As for the X-ray diffraction patterns, acorn starch from both varieties displayed an A-type pattern. Comparing the properties, Quercus coccifera acorn starch exhibited higher values for the light transmittance values, the solubility, the swelling power and the gelatinization temperatures than Quercus ilex acorn starch. However, the transition enthalpy of Quercus coccifera acorn starch was the lowest among the studied parameters. These results indicate that these properties are significantly (p<0.05) different depending on the oak variety.

A significance difference was recorded in the parameters pertaining to antioxidant system includes catalase, SOD and APX activity were found to increase substantially when the plants kept under stress conditions (250C/ 240C day and night temperature) than the plants kept under controlled condition (250C/150C day and night temperature). The percent increase in the antioxidant enzyme activity was found to be more in the tolerant genotype (HUW-234) than in the susceptible genotype (Sonalika). There was 23.52 % increase was reported in the catalase activity by tolerant genotype when kept under stress conditions than those kept under control. Significant reductions were reported in most of the photosynthetic and membrane parameters viz., chlorophyll ‘a’, chlorophyll ‘b’ and membrane thermostability index. Similar percent reduction was reported with respect to biochemical parameters (total protein content, starch content and soluble sugar content) in the susceptible variety kept under high night temperature regime.

To determine whether Lentinula edodes (L edodes) cultured on eucalyptus chips in the Ecuadorian highland generates antioxidant metabolites and anti-inflammatory effects. Methods. Total phenolic content was determined by the Folin-Ciocalteu reaction, the in vitro antioxidant activity of L edodes extracts was evaluated by the DPPH method and the in vivo anti-inflammatory activity was studied in mice. The chemical composition was studied by phytochemical screening and gas chromatography/mass spectrometry (GC/MS). Results. Total phenols were higher in extracts with increasingly high-water content. The antioxidant activity was robust and significantly strong in these extracts, suggesting the active metabolites are water-soluble. The anti-inflammation activity was significant in aqueous extracts only. Phytochemical screening indicated an overall similar composition to the literature reported earlier. GC/MS detected galactitol, trehalose, xylitol, phosphoric acid and octadecanoic acid among the most abundant metabolites. Conclusions. Cultivation on eucalyptus biomass at the Ecuadorian highlands retains the overall chemical composition, the phenolic content, antioxidant levels, and the in vivo anti-inflammatory activity of L edodes. The 11.3% content of trehalose observed is interesting for its capacity to control cellular stress damage.
