Creator:: Streeter, Donald J.
Abstract:: Centuries of continuous grain cropping in northern Africa have reduced N levels in soils to a degree such that agricultural production is now largely dependent upon nitrogen fertilizer. Through the identification of highly effective legume and Rhizobium strain combinations, the production of protein-rich livestock forage and green manure can be...

Creator:: Mao, Meiyu
Abstract:: Agrobacterium rhizogenes has been shown to cause root proliferation and increased water use efficiency in certain woody dicots. Root proliferation may be desirable in herbaceous legumes as a means of increasing potential sites for infection by Rhizobium species and subsequent nodulation and nitrogen fixation. Thus, A. rhizogenes was used to...

Creator:: Eardly, Bertrand D.
Abstract:: Nitrogen fertilization of seedling legumes is a controversial practice intended to provide N to the plant during periods when seed N, soil N, and N₂ fixation may not meet plant requirements; eg. prenodulation, postharvest, or in the event of an inoculation failure. Field experiments were conducted in 3 consecutive years...

Creator:: Lopez-Jurado, Gerardo
Abstract:: Field experiments were established in 1982 and 1983 on a Woodburn silt loam soil (Aquultic Argixeroll) to examine the effect of S fertilizer on dinitrogen fixation and dry matter yield of 10 week-old seedling alfalfa (Medicago sativa L. cv. 'Apollo'). Six levels of S fertilizer (0 to 67.2 kg S/ha)...

Full Text:: indigenous rhizobia are ineffective or submaximal in their N 2 -fixing capacity (Vincent, 1974). Early

Creator:: Nyunt, San
Abstract:: Germination of meadowfoam (Limnanthes alba Benth.) seed is inhibited by warm soil temperatures. This has led to recommendations for planting from early to mid-October when soil temperatures are below about 15°C. Objective data on the effects of planting date on stand establishment and yield are not available. These studies were...

Full Text:: the well-known response of many weed species to germinate when near the surface (Vincent and Roberts

Creator:: Seddigh, Majid
Abstract:: A field study was conducted in 1978 and 1979 at the Hyslop Crop Science Field Laboratory near Corvallis, Oregon, to determine the optimum capsule harvest date of Papaver bracteatum Lind. for thebaine yield and oil yield, while maintaining an acceptable percentage of seed germination. Accessions PI 383309 and PI 381607...
