Water use efficiency (WUE) provides a direct measure of the inextricable link between plant carbon uptake and water loss, and it can be used to study how ecosystem function varies with climate. We ana...
2022年8月28日,南京农业大学耕作制度与农田生态课题组的最新研究成果“Temporal complementarity be tween roots and mycorrhizal fungi drives wheat nitrogen use efficiency”在New Phytologist上发表。该成果揭示了氮高效小麦品种在花前依赖根系吸收氮素而花后依赖丛枝菌根真菌(AMF)促进花前...

氮素是植物生长发育所需的大量元素之一,水稻是我国的主要粮食作物,水稻生产对氮的需求仅次于水,是构成水稻生长成本的主要部分。目前,水稻氮肥表观利用率只有39%,即施氮肥量的50%以上残留在环境中。因此,在保证产量不减的基础上如何提高氮肥的利用效率,减少氮肥的使用量是我国农业可持续发展亟待解决的重要问题。
We explored the relationship between tree growth, water use, and related hydraulic traits in Populus deltoides Bartr. ex Marsh.and hybrid clones, to examine potential trade-offs between growth and wat...
The study compares the effects of: timer (‘Timer’) and soil moisture sensor-controlled irrigation on soilless lettuce; two volumetric water content (Θ) thresholds for irrigation (0.30 (‘Θ = 0.3’) and ...
Foresters frequently lack sufficient information about thinning intensity effects to optimize semi-natural forest management and their effects and interaction with climate are still poorly understood....
Six trials were conducted on sandy soils and muck soils in Hendry County and Palm Beach County, Florida, USA. Before planting cv. Caprice snap bean, plots were fertilized with different P applicat...
Field experiment was conducted for one growing season (2012) in clay loam soil at the Experimental Farm of Faculty of Agriculture, Southern Illinois University at Carbondale (SIUC), USA on soybean cro...
Attitudes regarding traditional energy sources have shifted toward renewable resources. Specifically, short-rotation woody crop supply systems have become more prevalent for biomass and biofuel produc...
Irrigation studies provide a framework for evaluating agricultural production and the water resource management in locations where water is scarce. Field experiments were conducted at Barbalha- CE (no...
Agricultural systems based on crop rotations favour sustainability of cultivation and productivity of the crops. Wheat-forage crops rotations (annual winter binary mixture and perennial alfalfa meadow...
In irrigation schemes under rotational water supply in semiarid region, the water allocation and irrigation scheduling are often based on a fixed-area proportionate water depth with every irrigation c...
Water stress effects on seed yield and water use efficiency of three indeterminate guar (Cyamopsis tetragonoloba L. Taub.) lines (L12, L18 and L33) were investigated in the experimental farm of the Fa...
The study examined resource use efficiency in Sesame production under organic and inorganic fertilizers applications in Keana Local Government Area, Nasarawa State. Multi-stage random sampling was us...
