Positive genetic correlation between forage yield and fiber of smooth Bromegrass
Voluntary intake potential of a forage crop is generally considered to be the most important feed characteristic regulating animal performance. Efforts to develop forage crops with reduced bulk volume, measured by neutral detergent fiber (NDF) concentration, have been associated with reduced plant fitness. The objective of this study was to evaluate a second cycle of divergent selection for NDF ...

Thiamethoxam: Assessing flight activity of honeybees foraging on treated oilseed rape using RFID technology
This study was designed to assess homing behaviour of bees foraging on winter oilseed rape grown from seed treated with thiamethoxam (as Cruiser OSR) with one field drilled with thiamethoxam treated seed and two control fields drilled with fungicide‐only treated seed. Twelve honeybee colonies were used per treatment group, 4 each located at the field edge (on‐field site), at approximately 500m ...

Italian ryegrass management effects on nitrogen supply to a subsequent potato crop
There is increasing use of Italian ryegrass (Lolium multiflorum Lam.) as a green manure in potato (Solanum tuberosum L.) rotations; however, effects of its management on soil N supply to the subsequent potato crop are unknown. Fertilizer N management and plow-down date for a preceding Italian ryegrass crop, ‘Lemtal’, on soil N supply to a subsequent potato crop, ‘Russet Burbank’, was determined ...

Nitrogen fixation of Sulla under Mediterranean conditions
Sulla coronaria (L.) B.H. Choi & H. Ohashi (=Hedysarum coronarium L.) is a Mediterranean forage legume grown extensively in rainfed Italian environments. Here we report the field quantification of its seasonal and annual N fixation, using the 15N isotopic dilution (ID) method, the influence of various nonfixing reference species on these estimates, and the allocation of fixed N between the ...

High yielding organic crop management decreases plant-available but not recalcitrant soil phosphorus
Phosphorus is a nonrenewable resource, raising concerns that agricultural practices may deplete reserves. Organic farming with low P inputs can result in deficient levels of plant-available phosphorus (available-P). The purpose of this study was to determine if common organically managed rotations are depleting P reserves or if large reserves still exist in unavailable forms. The research was ...

Focal bird species and risk assessment approach for non‐agricultural grassland scenarios in Central Europe
The European Food Safety Authority guideline on risk assessment identifies pesticide exposure scenarios for non‐target wildlife, however this scheme is not applicable to non‐agricultural grassland. For example, different habitats and human utilisation on golf courses attract bird communities that differ from those found in agricultural fields with annual crop cycles. The present study ...

Managing grackles: Deter one of summer’s most invasive birds
Grackles are difficult birds to manage, as they are an abundant and invasive type of blackbird. Because of this, grackles often require more effort and attention to control compared to other similar bird species. These birds live year-round in the southeastern United States, especially in Texas and Florida, but migrate to the North and Midwest during summer. Grackles like agricultural fields and ...

Crop rotation and nitrogen input effects on soil fertility, maize mineral nutrition, yield, and seed composition
Knowledge of complex relationships between soils, crops, and management practices is necessary to develop sustainable agricultural production systems. Objectives were to determine how maize (Zea mays L.) would respond to monoculture (C-C), 2-yr rotation (C-S) with soybean [Glycine max (L.) Merr.], or 4-yr rotation (C-S-W/A-A) with soybean, wheat (Triticum aestivum L.), and alfalfa (Medicago ...
