EARLY SEASON INSECT/VIRUS STUDY, 2005

Influenza in Canada: 2005-2006 season.

The Importance of Early Season Phosphorus Nutrition

Phosphorus (P) fertilization is a major input in crop production on the Great Plains, as many soils lack sufficient P for effective crop production. To optimize crop nutrition, P must be available to the crop in adequate amounts early in the growing season. Phosphorus is needed from the earliest stages of crop growth, because it is important in nearly all energy-requiring processes in the plant...

Adamantane resistance among influenza A viruses isolated early during the 2005-2006 influenza season in the United States.

CONTEXT The adamantanes, amantadine and rimantadine, have been used as first-choice antiviral drugs against community outbreaks of influenza A viruses for many years. Rates of viruses resistant to these drugs have been increasing globally. Rapid surveillance for the emergence and spread of resistant viruses has become critical for appropriate treatment of patients. OBJECTIVE To investigate th...

Association of transpiration efficiency with N2 fixation of peanut under early season drought

Peanut is grown mostly in rainfed areas where drought is a recurring problem. Peanut genotypes with high transpiration efficiency (TE) use less water and produced yield better under drought conditions. Specific leaf area and SPAD chlorophyll meter reading are used as surrogate traits for TE. N2 fixation (NF) is also used as a surrogate trait for yield under drought. The objective of this study ...

Qualifying Native Warm-Season Grasses and Early Succession Habitat

Tall fescue and other non-native perennial cool-season grasses (such as orchardgrass, timothy, bromegrasses, and bluegrass) provide poor wildlife habitat. Native warm-season grasses (nwsg), especially big and little bluestem, indiangrass, and switchgrass, have been promoted to replace non-native cool-season grasses and enhance quality early succession habitat. Initially, problems associated wit...
