▪ Abstract New evidence confirms earlier postulates that root signals to shoots, including
abscisic acid, nitrate flux, and cytokinins, modify whole plant growth processes including leaf …

Crop residues have value when left in the field and also when removed from the field and sold
as a commodity. Reducing soil water evaporation (E) is one of the benefits of leaving crop …

Winter wheat (Triticum aestivum L.) is the most common dryland crop grown in the central
Great Plains. Producers in this region include fallow in the rotation to minimize yield variability …

… use of particular collaborative skills are discussed in McManus and Aiken (In review) and
regarding user satisfaction is discussed in McManus and Aiken (In press, 1995). Though this …

… This Golden Rule for the use of computers in education (Aiken and Aditya, 1997; Aiken,
1989) is closely related to our negative and positive meta-principles. We would like to be taught …

Water absorption is influenced by the geometric distribution of viable roots and the availability
of water at root surfaces. Utilization of additional plant energy for the extensive and …

Water supply frequently limits crop yield in semiarid cropping systems; water deficits can
restrict yields in drought‐affected subhumid regions. In semiarid wheat (Triticum aestivum L.)‐…

Sorghum [Sorghum bicolor (L.) Moench] grain yield is severely affected by abiotic and biotic
stresses during post-flowering stages, which has been aggravated by climate change. New …

Corn (Zea mays L.) was grown on a deep, well drained silt loam soil (Aridic Argiustolls) at
Colby, Kansas, from 2004 to 2007 using three plant densities (66,300, 74,500, or 82,300 …

Increasing water and radiation use efficiencies (WUE and RUE, respectively) are critical to
enhance crop production. Exploring genetic variability in WUE and RUE is necessary to …
