Bean yield loss in response to volunteer corn

Control of volunteer adzuki bean in soybean

The objective of this research was to evaluate the efficacy of various pre-emergence (PRE) and post-emergence (POST) herbicides for the control of volunteer adzuki bean (Vigna angularis (Willd.) Ohwi & Ohashi) in soybean (Glycine max L.). Trials were conducted at two locations in 2005, 2006, 2007, and 2009. Experiments were arranged in a randomized complete block design with either five PRE or ...

Corn yield response to polymer and non-coated urea placement and timings

Poorly drained claypan soils can increase the importance of tillage and N management for corn (Zea mays L.) production. Field research in 2008, 2009 and 2010 (high rainfall years) near Novelty, MO (40° 1' N, 92° 11' W) sought to determine the effect of polymer-coated urea (PCU) placement [strip-tillage (ST) deep banded and no-till (NT) broadcast] and application timing (fall, early preplant...

Corn grain yield responses to tillage systems and plant densities

Alteration of Water Relations and Yield of Corn Genotypes in Response to Drought Stress

The influence of drought stress on internal water status and the final grain yield of three Egyptian corn (Zea mays L.) genotypes; GIZA2, TWC310 and TWC320 at different developmental stages was investigated. Plants grown in pots were subjected to four levels of water stress at vegetative and tassel emergence stages. Exposure of plants to drought led to noticeable decreases in leaf water potenti...

The Role of Volunteer Citizens in Response to Accidents and Disasters

Background: Many organizations, especially at the time of accidents, disasters, and critical conditions, cannot provide their services without the presence of volunteers. When accidents and disasters occur, the first persons who normally appear at the scene are citizens. Volunteer citizens with the skills and local knowledge can play important roles when accidents and disasters occur and can pr...
