Summary: Grain protein content (GPC) is an important factor affecting rice quality and nutrition, and there are significant differences in GPC among different varieties. This study compared high GPC (H-GPC) and low GPC (L-GPC) japonica rice varieties in terms of grain yield, dry matter production, and nitrogen uptake and transport. The results showed that L-GPC varieties had higher grain yield and dry matter production, but lower nitrogen uptake during the grain-filling period compared to H-GPC varieties. GPC was mainly influenced by the amount of nitrogen available for grain development per unit sink capacity.

Summary: Wheat is a crucial crop and has been selectively bred for improved performance since ancient times. Grain protein content (GPC), which is controlled by multiple genomic loci and influenced by the environment, is an important trait in breeding programs. This review summarizes recent genetic research on wheat GPC and grain protein deviation (GPD), as well as the performance of genomic prediction models for these traits. The study identifies 364 significant loci related to GPC and GPD on the hexaploid wheat genome, with a focus on two regions on chromosomes 3A and 5A. Overlapping independent QTL from different studies suggest stable genomic regions with potential for improving grain quality.

Summary: The study showed that newer varieties such as Tommi and Julius had higher apparent fertilizer nitrogen recovery rates and increased grain yield and protein concentration compared to older varieties like Diplomat, Kanzler, Orestis, and Ritmo when different nitrogen fertilizer treatments were applied at three different dates. While older varieties exhibited a negative linear correlation between grain yield and protein concentration, the newer varieties responded differently, showing stable protein concentration with rising grain yield under certain nitrogen application levels. This difference was possibly due to a more pronounced post-anthesis nitrogen uptake.

Summary: In this study, we found that growth duration is positively correlated with rice yield and nitrogen recovery efficiency through screening mutant lines. The mutant lines had shorter growth duration compared to the overexpression line O8, but showed no significant difference in other indicators. This provides a new idea for balancing rice yield and growth duration.

Summary: The effects of different nitrogen application rates and irrigation conditions on rice yield and nitrogen recovery efficiency were studied. The results showed that reasonable nitrogen management and irrigation mode can increase the yield of double-cropping rice. Late-season rice achieved higher yield with less nitrogen fertilizer, while early-season rice achieved the highest yield but with decreased nitrogen recovery efficiency. Improving nitrogen fertilizer and irrigation management can further enhance the yield potential of double-cropping rice.

Summary: Improving the yield and quality of wheat is crucial for global food security. Enhancing nitrogen use efficiency (NUE) in wheat is a significant approach to achieve this. This review provides a comprehensive understanding of the factors involved in wheat nitrogen uptake, assimilation, and remobilization. The complex trait of NUE is influenced by transporter proteins, kinases, transcription factors, micro RNAs, as well as enzymes and interactions with carbon metabolism. Mapping QTLs and molecular markers can help identify genetic resources for breeding programs. Exploring morphological, physiological, and biochemical traits in the selection process, along with utilizing new technologies, can accelerate NUE improvement.

Summary: Based on Vavilov's Law, the study confirms grain traumatization in standing crops due to enzyme-mycotic seed depletion (EMSD) and identifies open and hidden harmfulness parameters. The degree of pathogen contamination in grains is determined by favorable humidity and temperature conditions, as well as by the grain's hydrolytic enzymes during EMSD. Preserving grain quality is usually achieved by maintaining a moisture level that prevents further spread of fungi. Genetic sources of resistance to EMSD have been found in the VIR world collection for future selection and breeding of resistant varieties.

Summary: This study explores the integration of geostatistics and fuzzy logic in GIS for modeling soil pollution. Soil samples from the northern Nile Delta were analyzed for Cd, Co, Cu, Pb, Ni, and Zn concentrations. Metal distribution maps were generated using ordinary kriging methods and normalized using fuzzy membership functions and operators. The best-fit semivariogram models were identified and the resulting maps were validated using ROC analysis. The study highlights the importance of considering non-linear FMFs for accurate modeling of soil pollution and suggests the superior decision-making ability of the fuzzy Sum model.

Summary: Legume-cereal intercropping systems are more resource-efficient, but their response to water and N co-limitation has been poorly studied. This study assessed the relationship between N and water use efficiency in chickpea-durum wheat intercropping under different climate and N supply conditions. The results showed that sole-cropped wheat had higher water use efficiency relative to grain yield and biomass at all sites, except for biomass in S2. Intercropping increased water use efficiency in chickpea and durum wheat under both semi-arid and sub-humid conditions, and also improved N use efficiency compared to monocultures. Protein accumulation in mixed crops was enhanced, particularly under moderate N-application and sub-humid climate. Intercropping also increased chlorophyll content in durum wheat under sub-humid conditions. Overall, rain-fed chickpea-wheat intercropping can optimize water and N use and improve growth and yield quality in different climates.

Summary: Traditional mapping methods are costly and unable to accurately depict the dynamics of soil salts in space and time. In this study, the capacity of Landsat 8 OLI data to retrieve soil salinity and sodicity was tested in an arid landscape. Linear regression models were constructed to estimate soil pH, electrical conductivity (EC), and exchangeable sodium percentage (ESP), and the models were validated using different bands of OLI data. The results showed that soil pH had weak variability, while EC and ESP had large variabilities. The NIR band of OLI data was effective in discriminating soil salinity and sodicity levels.

Summary: The use of multispectral aerial photography data contributes to the study of soybean plants by obtaining objective data. The evaluation of field germination of soybean crops was carried out using multispectral data (MSD). The purpose of this study was to develop ranges of field germination of soybean plants according to multispectral survey data from an unmanned aerial vehicle (UAV) for three years (2020, 2021, and 2022). A DJI Matrice 200 Series v2 unmanned aerial vehicle and a MicaSense Altum multispectral camera were used for multispectral aerial photography. The correlation between ground-based and multispectral data was 0.70-0.75. The developed software for the automatic evaluation of the germination of soybean crops contributed to the assessment of the germination level of soybean breeding crops using multispectral aerial photography data. The software considers data of the three vegetation indices and calculated ranges, and creates an overview layer to visualize the germination level of the breeding plots. The developed method contributes to the determination of field germination for numerous breeding plots and speeds up the process of breeding new varieties.
