While no-till (NT) cropping systems can provide conservation benefits in the northern Corn Belt, adoption has been low due to concerns about potential yield reductions and economic risk. Strip-tillage (ST) systems have been proposed as an alternative that may provide many of the conservation...

Stable straw and grain yield constituted a challenging objective for breeders to cope with environmental changes as salinity increase. For this purpose, an assessment of grain yield (GY) and yield components stability of 25 durum wheat genotypes was conducted in three semi-arid sites differing...

To develop a water-saving planting pattern in the North China Plain, in the 2010–2011 and 2011–2012 winter wheat growing seasons, 2 types of planting patterns (wide-precision planting and conventional-cultivation planting) and 3 different irrigation treatments (60.0-mm irrigation at both...
