Nitrogen dynamics and budgets in a clay loam soil (Meadow Aqualf) in the North China Plain were investigated in a winter wheat (Triticum aestivum L.) and maize (Zea mays L.) cropping system comparing the effects of four N rates (0,and kg N ha −1 as urea) applied twice to each crop over 2 um nitrogen (NH 4-N) in the soil profile remained at a low and constant level Nitrogen use efficiency of wheat as affected by preceding crop, application rate of nitrogen and crop residues Article (PDF Available) in Australian Journal of Crop Science 4(5) July with   A 3-year side by side experiment on durum wheat and barley, under different water regimes and nitrogen levels, was carried out in a typical Mediterranean environment of Southern Italy, to identify the outstanding features of these species that contribute to enhanced grain yield and improved water and nitrogen use :// For the first comparison, three cover crop species were planted: hairy vetch (Vicia villosa) seeded at kg ha −1, winter wheat (Triticum aestivum) seeded at kg ha −1, and a mix (“bi-culture”) of hairy vetch and winter wheat seeded at and kg ha −1, respectively.

To capture the effect of cover crop alone, each of the The insights gained from the long-term impacts of tillage and N fertilization on soil fertility are crucial for the development of sustainable cropping systems.

The objectives of this study were to quantify the effects of 75 years of tillage and N fertilization on macronutrients in soil and wheat (Triticum aestivum L.) tissues grown in a winter wheat–summer fallow :// A rice-wheat sequence that yields 7 t ha-1 of rice and 4 t ha-1 of wheat removes more than NP 30 and K kg ha-1 from the soil; the residues of rice and wheat amount to as much as t For example, due to its deep root growth and nutrient uptake (down to 25 m), winter wheat was found to have better grain yields than spring wheat grown without previous winter catch crop (Thorup-Kristensen et al., ).

This was due to the fact that deep winter wheat roots retrieved more nitrogen from the lower parts of the profile than Background There has been renewed global interest in both genetic and management strategies to improve root system function in order to improve agricultural productivity and minimize environmental damage.

Improving root system capture of water and nutrients is an obvious strategy, yet few studies consider the important interactions between the genetic improvements proposed, and crop CRIMSON CLOVERTrifolium incarnatum Type: winter annual or summer annual legume Roles: N source, soil builder, erosion prevention, reseeding inter-row ground cover, forage Mix with: rye and other cereals, vetches, annual ryegrass, subclover, red clover, black medic See charts, p.

Nitrogen uptake by rice was significantly increased by the application of FN and GM. Mean 3‐yr total N uptake by rice grain and straw was 47 kg ha −1 in the control (FN 0), 84 kg ha −1 in FN 60, kg ha −1 in FNkg ha −1 in GM 20 and kg ha −1 in the GM 40 ://   Grasses have a large requirement for nitrogen and if not removed either prior to the crop year or during the season, reduce the amount of nitrogen available to the wheat crop.

Unless soil nitrogen supply is abundant, this often results in reduced grain protein percentage as well as reduced grain yield (Table ).

TABLE Introduction. The pH of agricultural soils is almost always measured in water, although m calcium chloride is sometimes used for research purposes (e.g. Blake et al., ) because it simulates the soil solution better than agricultural soils usually have a pH in water of between 5 (unlimed mineral soils) and (chalky or limestone soils).

However, previous genetic studies have failed to consider the impact of the local environment on the genetic differentiation of A. mongolicus populati. Agroecosystem nitrogen (N) loss produces greenhouse gases, induces eutrophication, and is costly for farmers; therefore, conservation agricultural management practices aimed at reducing N loss are increasingly adopted.

However, the ecosystem consequences of these practices have not been well-studied. We quantified N loss via leaching, NH3 volatilization, N2O emissions, and N retention in plant Sap-feeders are particularly sensitive to the quality and amount of usable nitrogen available from host plants (Rae and JonesNevo and CollDouglasWang et al.Hosseini et al.Nowak and KomorSauge et al.

).Senescence is a tightly regulated developmental program coordinated by transcription factors. Identifying these transcription factors in crops will provide opportunities to tailor the senescence process to different environmental conditions and regulate the balance between yield and grain nutrient content.

Here, we use ten time points of gene expression data along with gene network modeling to
