Effects of Different Tillage Systems on Soil Properties, Root Growth, Grain Yield, and Water Use Efficiency of Winter Wheat (Triticum aestivum L.) in Arid Northwest China
Published 2012-08-01Get full textAbstract: Studies on root development, soil physical properties, grain yield, and water-use efficiency are important for identifying suitable soil management practices for sustainable crop production. A field experiment was conducted from 2006 through 2008 in arid northwestern China to determine the...

Grain yield and N uptake of maize in response to increased plant density under reduced water and nitrogen supply conditions
Published 2024-01-01Get full textThe development of modern agriculture requires the reduction of water and chemical N fertilizer inputs. Increasing the planting density can maintain higher yields, but also consumes more of these restrictive resources. However, whether an increased maize density can compensate for the negative effec...

Maize and Pea Root Interactions Promote Symbiotic Nitrogen Fixation, Thereby Accelerating Nitrogen Assimilation and Partitioning in Intercropped Pea
Published 2025-07-01Get full textCereal/legume intercropping enhances legume nodulation and improves nitrogen use efficiency (NUE) in cereal crops. This facilitation of symbiotic nitrogen fixation (SNF) in intercropped legumes involves a complex eco-physiological mechanism driven by multiple factors. Among them, interspecific root...

Review on physiological and ecological characteristics and agronomic regulatory pathways of intercropping to delay root and canopy senescence of crops
Published 2025-01-01Get full textIntercropping has been widely used in arid and semi-arid regions because of its high yield, stable productivity, and efficient utilization of resources. However, in recent years, the high yield of traditional intercropping is mainly attributed to the large amount of purchased resources such as water...

No-tillage with straw mulching boosts wheat grain yield by improving the eco-physiological characteristics in arid regions
Published 2023-11-01Get full textStraw returning to the field is a technical measure of crop production widely adopted in arid areas. It is unknown whether crop yield can be further increased by improving the eco-physiological characteristics when straw returning is applied in the crop production system. So, a three-year field expe...
