A field experiment was conducted to determine the seasonal patterns of arbuscular mycorrhiza (AM) in a dryland winter wheat (Triticum aestivum L.) system and to determine wheat growth and P uptake responses to inoculation with mycorrhizal fungus. Broadcast-incorporated treatments included (1) no inoculation with mycorrhizal fungus, with and without P fertilizer, and (2) mycorrhizal fungal inocu...

Soil infertility is the main barrier to dryland agricultural production in China. To provide a basis for the establishment of a soil amelioration technical system for rainfed fields in the semiarid area of northwest China, we conducted a four-year (2007-2011) field experiment to determine the effects of wheat straw incorporation on the arid soil nutrient levels of cropland cultivated with winte...

Grain number is a major trait for wheat yield under dryland farming. An International Triticeae Mapping Initiative (ITMI) mapping population comprising 105 recombinant inbred lines (RIL) developed from a cross between a Synthetic hexaploid wheat (Triticum aestivum) 'W7984' and a spring wheat variety 'Opata M85' was used to identify quantitative trait loci (QTL) associated with grain number per ...

dryland winter wheat (triticum sativum l.) generally grown in rotation with fallow or chickpea (cicer arietinum l.) constitutes a major crop in the west region of iran. information is limited on the success of more intensive dryland cropping systems while applying conservation tillage management. an experiment was conducted to determine the effect of five tillage systems on soil physical proper...

this study was conducted to investigate economic aspect and some soil properties in different crop rotations of wheat in dryland conditions in sararood - kermanshah during six years 2006-2012. the experiment carried out based on randomized complete block design (rcbd) with four replications in two neighbor sites. treatments were wheat-wheat, fallow - wheat, chickpea-wheat, vetch-wheat and saffl...

of Research Findings Soil quality parameters were assessed at several long-term dryland cropping systems research sites in eastern Washington to further define management practices that are soil building rather than degrading. The objective was to characterize soil quality changes over time as affected by no-till versus traditional tillage-based management systems. Soil organic carbon slowly in...

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...

Water shortage and nitrogen (N) deficiency are the key factors limiting agricultural production in arid and semi-arid regions, and increasing agricultural productivity under rain-fed conditions often requires N management strategies. A field experiment on winter wheat (Triticum aestivum L.) was begun in 2004 to investigate effects of long-term N fertilization in the traditional pattern used for...
