Pseudoreplication and Session-Level Variability in CAN-Bus Tractor Telemetry: Mixed-Effects and Machine-Learning Analysis

This study analyzes high-frequency CAN-Bus telemetry from a power-shuttle tractor to demonstrate that session-level variability is the dominant source of engine-load variation, significantly outweighing implement type, thereby highlighting the critical need to address pseudoreplication and non-independence in agricultural machine-learning research.

Validation of a splice-site polymorphism in LprTFL across diverse Indian bean germplasm reveals photoperiod-dependent modulation of determinacy

This study validates a G-to-A splice-site polymorphism in the LprTFL gene as the primary determinant of growth habit in Indian bean germplasm, while highlighting the role of photoperiod and potential epigenetic mechanisms in modulating this trait.

Cd, Cr, and Pb concentrations increase in maturing compost while the metal inventory does not: implications for compliance sampling and digestion protocols

This study demonstrates that apparent increases in Cd, Cr, and Pb concentrations during compost maturation are artifacts of improved analytical recovery from a humifying matrix rather than actual metal accumulation, necessitating that compliance sampling be tied to independent maturity criteria and utilize near-total digestion protocols to avoid false exceedances.

Nonlinear climatic regulation of flowering phenology in sugarcane wild relatives revealed through mixed- effects and survival modelling

This study reveals that flowering phenology in sugarcane wild relatives is governed by nonlinear climatic regulation, where relative humidity, rainfall, and solar radiation act as dominant predictors of flowering initiation, with environmental variability exerting a significantly stronger influence than genotypic differences.

How can crop production adapt to growing groundwater restrictions in the U.S. West?

This study employs an integrated modeling approach to demonstrate that the optimal adaptation to groundwater restrictions in the U.S. West involves a spatially heterogeneous portfolio of strategies, primarily combining deficit irrigation and cropland reduction in water-scarce regions like California and the Southwest with a geographic shift of production to states with greater water availability.

Bacillus coagulans inoculation generates an alternative microbial succession trajectory associated with nitrogen preservation and aerobic stability in alfalfa silage

This study demonstrates that inoculating alfalfa silage with *Bacillus coagulans* establishes a unique, staged microbial succession trajectory that outperforms traditional *Lactiplantibacillus plantarum* inoculation by significantly enhancing nitrogen preservation and extending aerobic stability through distinct functional shifts in acetate production and nutrient retention.

Dynamics of microbial-derived nitrogen to increasing straw addition in two typical arable soils in Northeast China

This study demonstrates that increasing straw addition differentially affects microbial-derived nitrogen dynamics in Northeast China's arable soils, where Alfisol tends to retain nitrogen in the organic pool while Mollisol predominantly converts it into mineral nitrogen, with straw generally enhancing organic retention in Alfisol but having minimal impact in Mollisol.

In vitro germination and storage optimization of Fraxinus chinensis pollen

This study optimized the in vitro germination medium and storage conditions for *Fraxinus chinensis* pollen, identifying specific nutrient concentrations, a 25°C germination temperature, and a controlled thawing-rehydration protocol that achieved a 91.49% germination rate, while establishing 4°C and 25°C for short-term and -20°C and -80°C for long-term viability to support controlled hybridization efforts.
