In order to realize the maximum potential parameters of winter wheat productivity, it is necessary, first all, use high-yielding varieties with optimal quality indicators grain, as well progressive agricultural technologies aimed at obtaining a stable crop yield. Winter places high demands on its previous crops. Insufficient amount productive moisture in soil or extremely low reserves affects y...
Despite the dynamic nature of annual cropping systems, few studies have investigated how structure predator communities and their interactions with prey corresponds crop seasonality. Adding winter habitat, such as cover crops, improves soil health likely contributes seasonal habitat availability for arthropod communities. Stable may lead to functionally diverse predatory associated ecosystem se...
The growth and development of crops would not be separated by comprehensive climatic factors, such as temperature, precipitation, sunshine and others. To some extent, the behaviors of the climate factors have great affection on the climatic suitability of crops. In order to achieve the quantitative assessment of climate factors, the decision support system for quantitative calculation on climat...
Residue management in cropping systems is believed to improve soil quality. However, the effects of residue management on methane (CH4) and nitrous oxide (N2O) emissions from paddy field in Southern China have not been well researched. The emissions of CH4 and N2O were investigated in double cropping rice (Oryza sativa L.) systems with straw returning of different winter cover crops by using th...
Wheat yields in organic production are significantly lower than those achieved conventional farming systems and Northern Europe farmers also struggle to achieve the processing quality levels demanded by millers bakers, especially winter-wheat crops. Here, we report findings of a 3-year pilot study which investigated potential increasing grain both standard (e.g., protein specific weights) selec...
The current emphasis on sustainable agricultural systems has led to a renewed interest in the use of cover crops to reduce soil erosion losses and retain soluble nutrients during the dormant season. Cover crop choices include a broad range of plant material, such as ryegrass (Secufe cereale L.), winter wheat (Triticum aestivum L.), forage grasses, and legumes. Historically, cover crops were use...
The Farm Scale Evaluations (FSEs) showed that genetically modified herbicide-tolerant (GMHT) cropping systems could influence farmland biodiversity because of their effects on weed biomass and seed production. Recently published results for winter oilseed rape showed that a switch to GMHT crops significantly affected weed seedbanks for at least 2 years after the crops were sown, potentially cau...
land is used for crop production and can increase potential profit. There are ecological as well as economic advantages to increasing the amount of time the land is used for production. A winter grain crop, traditionally wheat, can act as a cover crop to prevent erosion. A warm-season double crop, often soybean, may yield smaller returns than a full-season crop but often averages a positive net...
