Dense subsoils limit winter wheat rooting depth and soil water depletion

Winter Wheat Growth in Artificially Compacted Soil

Effects of straw mulch on soil water and winter wheat production in dryland farming

The soil water supply is the main factor that limits dryland crop production in China. In a three-year field experiment at a dryland farming experimental station, we evaluated the effects of various straw mulch practices on soil water storage, grain yield, and water use efficiency (WUE) of winter wheat (Triticum aestivum). Field experiments were conducted with six different mulch combinations (...

Preliminary Study on Soil Moisture Forecast of Winter Wheat

Using four groups of survey data of soil moisture of winter wheat from returning green stage to harvest stage in Daxing region, the variation laws of soil moisture exponential depletion relations in 0-60cm depths during different growth stage are analyzed ,and based on soil moisture exponential depletion relations the forecast model of soil moisture depletion is built. The results indicate that...

Estimation of effective precipitation for winter wheat in different regions of Iran using an Extended Soil-Water Balance Model

Estimated Effective Precipitation (Pe) in dryland areas is an essential element of water resource management. Itrepresents the amount of precipitation available in the crop root zone to meet the needs of evapotranspiration. Thecurrent study compared different approaches for estimating Pe in different climatic zones of Iran. A two-layer soil–water balance (SWB) model was adopted based on the pro...

Study of Zinc effects on quantitative and qualitative traits of winter wheat in saline soil condition

An experiment was conducted to optimize consumption of Zinc and evaluate of Zinc effects on quantitative and qualitative traits of winter wheat under saline soil condition. It was done by three replications in randomized complete block design. The experiment had four treatments as Control without Zn, 40 Kg.ha-1 Zn as ZnSO4, 80 Kg.ha-1 Zn as ZnSO4 in soil and 120 Kg.ha-1 Zn as ZnSO4 in soil. Ele...
