Densities of 10, 20, and 30 hard red winter wheat kernels, Triticum aestivum L., were infested with different life stages of the rice weevil, Sitophilus oryzae (L.), mixed with 35 g of wheat treated with 300 ppm of the Protect-It (Mississauga, Ontario, Canada) formulation of diatomaceous earth (DE), and held at 22, 27, and 32 degrees C. A similar test was conducted by exposing densities of 6, 1...

New crop cultivars will be required for a changing climate characterised by increased summer drought and heat stress in Europe. However, the uncertainty in climate predictions poses a challenge to crop scientists and breeders who have limited time and resources and must select the most appropriate traits for improvement. Modelling is a powerful tool to quantify future threats to crops and hence...

We measured net atmospheric exchanges of energy and water vapor using eddy covariance along a chronosequence of Pinus elliottii plantations in north Florida: a recent clear-cut, a mid-rotation stand, and a 24-year-old, rotation-aged stand. Reflected energy averaged 0.26 of incoming solar radiation at the clear-cut and 0.18 at the closed-canopy stands. The sum of sensible (S), latent (LE) and so...

Repeated application of manures to agricultural soils could cause the accumulation of phosphorus (P) in soils. However, it is unclear if manure P can behave similar to P in soluble fertilizers in accumulation Olsen-P (0.5 mol L-1 NaHCO3 at pH 8.5) in soils. A long-term wheat-maize rotation experiment was conducted to investigate the effects of repeated application of manures on P accumulation i...

Abstract Aims Saprotrophic soil fungi participate in biomass mineralization, inhibit pathogen development and promote plant growth. Pathogens accumulate decrease crop yields. The structure of fungal communities is determined mainly by the organic matter content pH soil. Little known about influence rotation long-term monoculture on saprotrophic that decompose roots residues as sources biomass. ...

No-till dryland winter wheat (Triticum aestivum L.)-fallow systems in the central Great Plains have more water available for crop production than the traditional conventionally tilled winter wheat-fallow systems because of greater precipitation storage efficiency. That additional water is used most efficiently when a crop is present to transpire the water, and crop yields respond positively to ...

Blowing dust from excessively tilled fallow fields is a major soil loss and air quality concern in the low precipitation (<300 mm annual) wheat (Triticum aestivum L.) production region of the Inland Pacific Northwest (PNW) of the United States. A 2-year tillage-based winter wheat-summer fallow (WW-SF) rotation is practiced on >90% of rainfed cropland in the region. Earlier research proved the u...
