Summary: Feeding cereal grain to cattle is common practice for optimal beef and milk production. This study investigated the ruminal degradation patterns of common grains and the effect of steam pelleting on starch and crude protein degradability. Pelleting was found to improve the degradation of starch and crude protein in sorghum, barley, and wheat samples, with sorghum showing lower degradability compared to other grains.

Summary: The reaction of plants to simultaneous stress action and treatment with biological stimulants has been poorly studied. This study investigated the growth and yield of bread wheat (Triticum aestivum L.) under stress conditions and the effects of spraying with herbicide and growth-stimulating bacterium. The findings show that spraying with Chistalan reduced plant growth and inhibited root growth, while treatment with Pseudomonas protegens DA1.2 increased the IAA/ABA ratio and prevented root growth inhibition caused by the herbicide. Bacterization also improved water balance and increased grain yield in wheat plants under arid conditions.

Summary: In order to address the scarcity of mineral phosphorus resources and environmental issues arising from enhanced P losses, this study investigates the mechanical separation of phosphorus-rich grain fractions from wheat, rye, barley, and oats for reduced organic P content in animal feed. The utilization of the separated organic P, which is in the form of inositol P, for sustainable phosphorus management is also evaluated. The study finds that specific layers in the grains contain the highest concentrations of inositol P and phytase activity, and their removal could significantly reduce organic P content.

Summary: This study investigated the sulfosulfuron herbicide residues in wheat field soil using bioassay and laboratory methods. The results showed that the residues were stable for 90 days after herbicide use and then gradually decreased. Sulfosulfuron exhibited the highest toxicity to garden cress and the lowest toxicity to corn.

Summary: Diversity surveys of crop germplasm can provide insights into the genomic basis for plant architecture and grain yield improvement. In this study, exome sequencing of 287 wheat accessions revealed the presence of selective sweeps between landraces and cultivars, which contain genes known for yield improvement. Genome-wide association study identified genetic loci associated with yield potential and characterized two underlying genes that regulate plant height and grain weight. Additionally, the study proposed a working model for historical wheat breeding based on the interaction between these genes and a classical plant height locus.

Summary: The study tested the effects of three cytokinin derivatives and one cytokinin antagonist on spring barley and winter wheat, with the results showing a promoting effect of the derivatives on tillering and yield. The cytokinin antagonist also had stimulatory effects in winter wheat but inhibitory effects in spring barley. Analysis of endogenous cytokinins highlighted the importance of isopentenyl-adenine types in tillering of spring barley. Overall, the compounds show strong potential for future development of plant growth regulators.

Summary: The development of accurate multivariate models for grain yield (GY) prediction in wheat experimental trials using normalized difference vegetation index (NDVI) and additional agronomic traits is a promising option to replace laborious in-field evaluations. This study proposed improved GY prediction models by incorporating NDVI, plant height, phenology, and ear density from experimental trials. The best models included NDVI, days to heading, and ear density or plant height, which showed a significant increase in prediction accuracy and a decrease in root mean square error.

Summary: The study highlights the importance of using appropriate stress screening indices in evaluating and selecting nitrogen deficiency-tolerant wheat cultivars for improved yield and quality. Promising stress screening indices such as MP, GMP, HM, STI, and YI were identified for identifying tolerant cultivars to LN conditions. Cultivars like Sofru, BC Opsesija, and MV-Nemere were found to be the most tolerant to LN conditions for grain yield.

Summary: Water management is crucial for improving grain yield in the dryland systems of the Mediterranean basin. This study explored the potential of nitrogen (N) fertilisation to increase grain yield by improving water use efficiency. The results showed that durum wheat and barley responded positively to N fertilisation under rainfed cultivation, leading to an average increase of 26% in grain yield compared to unfertilised controls. The response to N fertilisation was observed in both low and high yield potential cases, with grain number per unit area and total biomass at maturity being the main factors influencing grain yield. Barley and durum wheat had similar responses to N fertilisation.

Summary: This article introduces a generic Bayesian network model called PRReSTo, which estimates likely infestation rates of host items in consignments. PRReSTo takes into account the vulnerability of host items to pest infestation, the abundance of pests to which host items are exposed, and the effects of risk-reducing measures. PRReSTo can be used to evaluate the effectiveness and acceptability of risk reduction measures in different pest-host systems.

Summary: Invasive tephritid fruit flies pose a significant threat to commercial fruit and vegetable production. Early detection is crucial, and male lures are an important component of trapping networks. This review aims to summarize data on the change in attractiveness of male lures during aging in the field, highlighting studies that relate trap captures to changes in residual content and release rate.

Summary: Colletotrichum and Alternaria species have become emerging fungal pathogens causing severe economic losses in citrus orchards in the Mediterranean area. The use of copper-based antimicrobials for disease management is increasingly problematic, and research for alternative formulations is encouraged. This study tested copper-alternative products on citrus orchards and found that they significantly reduced disease incidence and severity, often showing comparable or better efficacy than copper. The good efficacy of these products suggests their potential for sustainable and large-scale use in integrated and organic citriculture.

Summary: This study updated the economic thresholds for Lygus spp., a major insect pest of canola in Canada, by integrating a large data set collected over 23 years. The results revealed that the economic injury level for Lygus was around 9-23 insects per 10 sweeps, while spraying a foliar insecticide was only necessary when Lygus catches exceeded 30 insects per 10 sweeps. Additionally, analysis of Precision Yield Data showed that at low abundances (under 17 insects per 10 sweeps), Lygus may potentially stimulate canola yield and do not require control action.

Summary: The giant borer, Telchin licus, is a significant pest of sugarcane in Central and South America, and traditional control methods are ineffective due to the larvae's hiding behavior. Recent research has shown that transgenic sugarcane expressing Bacillus thuringiensis proteins, originally developed to control another sugarcane pest, can also effectively control the giant borer.

Summary: A novel methodology was proposed to analyze water-sensitive papers (WSPs) for evaluating spray quality. The segmentation of overlapping droplets based on concave point detection and ellipse fitting achieved high accuracy. A linear relationship between droplet density and coverage was observed, and simulated WSPs were generated for high coverage estimation. This approach allows for more accurate spray quality indicators from WSP collectors.
