Double-Cropped Soybean Response to Various Wheat Stubble Managements
Varying responses to wheat (Triticum aestivum L.) stubble management preceding double-crop soybean [Glycine max (L.) Merr.] have been reported; however, little work has been done in the Mid-Atlantic region of the United States. The objectives of this study were to observe the effects of wheat …

Notopleural Mutations Enhance Defects In Imaginal Disc Epithelial Morphogenesis And Macrochete Elongation Associated With Mutations in the Stubble-Stubbloid Locus
The Stubble-stubbloid locus encodes a transmembrane serine protease (Stubble) necessary for the proper formation of sensory bristles, and the morphogenesis of leg and wing epithelia. Genetic and cell biological analysis indicate a role for Stubble in actin cytoskeletal dynamics and cell shape …

The effects of flame cultivation on the growth and nitrogen utilization of winter barley
… unpopularity of uncontrolled straw and stubble burning, two field experiments were carried out to investigate the effects of burning stubble using the Calor Gas flame cultivator.<br/>Winter barley was sown in the 1986/87 and 1987/88 seasons using a range of seed bed preparation …

Growth analysis and regrowth potential of three cool season grasses in spring
… The non-structural carbohydrates in the stubble generally showed an inverse relation with the CGR. There were differences in total LAI among grasses when averaging the weekly cuts. The regrowth in the field after harvesting at different dates was found to be influenced by variation in …

Examining the effect of rotation sequence on biological nitrogen fixation of pulse crops
… BNF in pulse crops grown on oilseed and cereal stubble in the Brown, Dark Brown, and Black soil zones. Soil samples were collected from each rotation to characterize sites and identify soil physical, chemical, and microbiological properties that may have affected BNF in pulse crops. …

Northern pintail nest site selection, nest success, renesting ecology and survival in the intensively farmed prairies of southern Saskatchewan: an evaluation of the ecological trap hypothesis
… Most (51%) pintail nests were found in crop stubble and generally pintails nested in habitats in proportion to their availability on the landscape. In contrast, most (82%) mallard nests were located in edge and grassland habitats. Mallards nested in habitats with dense cover in greater …

Canopy, microenvironment, and nitrogen effects on summer recovery of tall fescue
… June all 6 treatments were mowed to prescribed stubble heights with a seventh unmowed check. Canopy light regimes, leaf area index, and regrowth of tillers were monitored along with soil, fair, and shoot temperatures in stubbles after the June harvest. Mowing more frequently in spring decreased …

Balance aparente de nutrientes (N,P,K) en dos unidades de producción ubicadas en el municipio de San Ramón, departamento de Matagalpa, durante el período 1997-1999
… with elrtremely low values. This due mainly to stubble burning, outputs of nutrients from harvesting, low fertilizer a.pplication etc.; these flwtors reduce the soíl nutritional reserves. In the case of Santiaao R.uiz's fium the balance obtained it's evident that fann presenta better state …

Tillering and carbohydrate content of orchardgrass as influenced by environmental factors
… in both chambers. Soluble carbohydrates in the stubble were associated with tillering. There was a marked increase in water soluble carbohydrates as light energy increased up to normal sunlight. Ory matter production was associated with tillering and carbohydrate contents of orchardgrass, …

Development of Sustainable Harvest Strategies for Cellulose-Based Biofuels: Harvest Effects on Game Bird Production
… bird production. Three haying treatments (10-cm stubble, 30-cm stubble and a no-harvest control) were assigned randomly to fields harvested in the fall of 2009 and 2010 prior to sampling the subsequent summers. Nests were located, identified by species, and followed to completion using the chain …

Phenological and Cultural Studies of Common Dandelion (Taraxacum officinale Weber)
… were clipped more frequently and at a lower stubble height exhibited less reproductive and vegetative vigor than plants that were clipped less frequently and at a higher stubble height.

Influence of Different Crops on the Population Dynamics of the Western Corn Rootworm, Diabrotica Virgifera Virgifera LeConte, in East Central Illinois
… (Zea mays L.), soybean (Glycine max L.), oat stubble (Avena sativa L.), and alfalfa ( Medicago sativa L.) on adult densities, ovary development, and oviposition of the new strain of western corn rootworm was studied. The influence of different planting dates on oviposition and emergence also …

THE INFLUENCE OF PULSE CROPS ON SOIL PHOSPHORUS AVAILABILITY TO SUBSEQUENT WHEAT CROPS IN THE BROWN SOIL ZONE OF SASKATCHEWAN
… observed in cereals grown on pulse vs. cereal stubble is due to differences in soil phosphorus (P) availability. The influence of pulse crops on soil P availability and P uptake by subsequent wheat (Triticumaestivum L.) crops was assessed in a series of laboratory experiments and field studies …

Development of Sustainable Harvest Strategies for Cellulose-Based Biofuels: The Effect of Intensity and Season of Harvest on Cellulosic Feedstock and Upland Nesting Game Bird Production
… on biomass yield (4) determine the effect of a stubble height (high-intensity, low-intensity, and a “no harvest” control) on nesting success of economically important bird species, (5) determine how vegetative structure and composition affect nesting success and diversity of economically …

Genetic Analysis Of Rhoa Signaling During Epithelial Morphogenesis In Drosophila
… RhoA signaling pathway and the product of the Stubble-stubbloid (Sb-sbd) locus, a transmembrane serine protease. Mutations in the Sb-sbd gene interact genetically with the members of the RhoA signaling pathway, however the nature of the relationship between Sb-sbd serine protease activity and …

Nontarget Avian Use of DRC-1339 Treated Plots During An Experimental Blackbird Control Program in Eastern South Dakota
… avicide and broadcast in eastern South Dakota stubble fields during the vernal migration. The potential negative impact on nontarget avian species, in particular ring-necked pheasants (Phasianus colchicus), was evaluated during the treatment periods, March to April 1998 and 1999. Nontarget …

Comparing simple and complex native forage mixtures for grazing cattle in southwestern Saskatchewan
… southwestern Saskatchewan. Clippings at a 5 cm stubble height occurred on June 20 and every 28 days after until October 10. Forage DM production, in vitro OMD, NDF, ADF, ADL, CP, Ca and P concentrations were measured. As species matured, production and OMD declined (P¡Ü0.05) but NDF, ADF and ADL …
