Fertilization with K and P impacts alfalfa (Medi- cago sativa L.) yield, but how these nutrients influence taproot reserves and gene expression is unknown. Our objectives were to determine how P and K impact (i) alfalfa yield and yield components, (i

Addition of P and K fertilizer can increase alfalfa (Medicago sativa L.) yield and stand persistence, but the yield components associated with P- and K-induced variation in agronomic performance are not clear. Our objectives were: (i) to determine th

The objective of this paper is to assess the effectiveness of alfalfa (Medicago sativa L.) improvement efforts over the last century, and with the advent of molecular biology, identify challenges for alfalfa improvement in the future. Yield trials co

Ammonia (NH3) emissions from poultry litter results in air pollution and can cause high levels of NH3 in poultry houses, which negatively impacts bird performance. The objectives of this study were to: (1) conduct a nitrogen (N) mass balance in broil

Many studies have shown a consistent pattern in adults' responses to affective pictures and there is growing evidence of gender differences, as well. Little is known, though, about children's verbal, behavioral, and physiological responses to affecti

Phosphorus and K fertilization increases alfalfa (Medicago sativa L.) yield and stand persistence, but the changes in yield components as affected by P and K fertility level are not known. Our hypothesis is that P and (or) K fertilization will increa

To delineate the acoustic parameters crucial for eliciting a cardiac deceleratory response in newborns, 2 experiments investigated stimulus dimensions implicated as important by previous research. In experiment 1, the temporal pattern and spectral co
