Abstract The two‐spotted spider mite (TSSM; Tetranychus urticae Koch) is a major pest of tomato (Solanum lycopersicum L.), causing substantial yield and quality losses in Ethiopia and worldwide. The present study evaluated the impact of tomato branch pruning and trellising on TSSM populations and yield in the Central Rift Valley tomato production area ...

Multiple ortho‐mosaicking software pipelines produce comparable imagery‐derived wheat phenotypes
Abstract Unmanned aerial systems (UAS) equipped with multispectral and RGB sensors offer valuable data for monitoring crop health and assessing disease severity. However, the wide range of available photogrammetric software complicates software selection for high‐throughput plant phenotyping.

Abstract Soybean [Glycine max (L.) Merr.] varieties are categorized into different relative maturity groups (MGs) that correspond to the approximate region that the variety is best adapted. Maturity is an important trait that growers consider when deciding which varieties to plant and for breeders as a covariate to compare genotypes.

Abstract An agronomic trait such as stand count is important for cultivar development and crop management practices. Manually counting the number of plants is time consuming, labor‐intensive, and prone to error. The use of unoccupied aerial systems (UAS)‐collected red, green, blue (RGB) imagery in conjunction with advanced deep learning and image ...

Since the 1980s defoliation (often assessed by means of crown transparency) is the most used indicator of tree condition adopted in Europe. It has been criticized for its subjectivity and scarce relation with meaningful endpoints. Here we collated the results of three different studies carried out in France and Italy to investigate the relationship ...

ABSTRACT The use of chemical fertilizers is economically and environmentally costly to produce and apply. Therefore, optimized fertilizer use is critical to increase or maintain crop yields. We evaluated the productive and nutritional characteristics of the Stylosanthes cv “Campo Grande” submitted to different cutting date and phosphate fertilization ...

The greenhouse thrips, Heliothrips haemorrhoidalis (Bouché, 1833), is an important avocado pest in New Zealand, where repeated infestations reduce leaf quality and tree vigour. To assess biological control stability under different predator assemblages, this study evaluated thrips population dynamics and predator survival across two sequential phases ...

ABSTRACT Feral deer are associated with a range of environmental impacts including overgrazing and trampling of native vegetation, increased insolation, ringbarking, creation of wallows, erosion and stream degradation. Consequences of invasive deer impacts can threaten vulnerable ecological communities and have the potential to alter long‐term ...

Lack of Hydraulic Acclimation in Response to Multiple Droughts and Recovery
ABSTRACT Human‐caused climate change is expected to bring more frequent and extended droughts with shorter wet periods of relief in between for many regions of the world. Critical knowledge gaps remain around the extent to which tree species can acclimate physiologically to repeated droughts.
