Soil phosphorus dynamics as affected by Congo grass and P fertilizer
Scientia Agricola, 2014 Some plant species can change soil phosphorus (P) availability and this may be an important tool in managing tropical high fixing phosphorus soils. An experiment was conducted to evaluate phosphorus transformations in the soil and phosphatase activity ...

Ensilability of the tropical grass 'Splenda' [PDF]
CrossRef Listing Of Deleted DOIs, 1995 Irrigated C4 photosynthesis grasses are more productive than C3 grasses in portuguese hot season, due to better use of nitrogen, water, high temperatures and solar radiation. The aim of this study was to evaluate the ensiling characteristics and limiting factors of ’Splenda’ (Setaria sphacelata var. sericea x S. sphacelata var. splendida).

Agribusiness, EarlyView.ABSTRACT Climate variability is affecting the productivity, profitability, and resilience of smallholder dairy producers in developing countries. The adoption of climate‐smart (CS) dairy practices has been promoted to mitigate these negative effects. However, while interest in dairy CS practices is growing, empirical evidence on their adoption patterns

Leveraging High-Resolution Satellite Imagery and Gradient Boosting for Invasive Weed Mapping
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020 An introduced pasture grass (Andropogon gayanus - gamba grass) is spreading through the tropical savannas of northern Australia, with detrimental ecosystem consequences including increased fire intensity.

American Journal of Botany, EarlyView.Abstract Premise Insect herbivory is a major biotic factor shaping plant populations and driving the evolution of defensive traits. Polyploidy (whole‐genome duplication) often induces substantial phenotypic and genotypic changes that may affect species interactions, including herbivory.

Shaped by context: Evolutionary trajectories of desiccation tolerance in land plants
American Journal of Botany, EarlyView.Abstract Desiccation tolerance (DT), the ability to survive near‐complete cellular dehydration, is widespread in diaspores but rare in the vegetative tissues of land plants. The patchy and punctuated phylogenetic distribution of vegetative desiccation tolerance (VDT) suggests that the trait is both ancient and recurrent, yet the evolutionary ...

Applications in Plant Sciences, EarlyView.Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.
