Long-term use of fallow in dryland wheat (Triticum aestivum L.) systems can increase erosion and decrease soil fertility. One possible solution is to grow a green manure crop during the fallow period. To evaluate the short-term effects of substituting a winter legume green manure for fallow in a 2-vr wheat rotation, a series of experiments were conducted in the Sacramento Valley of California f...

a system has been referred to as green fallow (Gardner et al., 1993). These systems have sometimes been sucGrowing a legume cover crop in place of fallow in a winter wheat cessful in the cooler regions of the northern Great Plains (Triticum aestivum L.)–fallow system can provide protection against (Zentner et al., 2001).

Zentner et al., 2001). Johnson (1982) found that income variability was reduced under summer fallow and that Suitability of alternative crops in the northern Great Plains remains summer fallow maximized return to land at low yields, a question because of water limitations. Objectives were to compare water use of an oat (Avena sativa L.)–pea (Pisum sativum L.) mix low wheat prices, and high N pr...

Winter wheat (Triticum aestivum L.) monoculture is conventionally cultivated followed by two to three months of summer fallow in the Loess Plateau. To develop a sustainable cropping system, we conducted a six-year field experiment to investigate the effect of leguminous green manure (LGM) instead of bare fallow on the yield and water use efficiency (WUE) of winter wheat and the soil water balan...

The phenomenon of syntenic genetic conservation of chromosomes enables application of molecular probes obtained from one species of animals to detect homologous DNA segments in another species. The aim of this study was identification of sex chromosomes in fallow deer (Dama dama), using in interspecies hybridizations in situ (Zoo-FISH technique) the bovine heterosomes painting probes. The resul...

The goal of this study was to map rainfed and irrigated rice-fallow cropland areas across South Asia, using MODIS 250 m time-series data and identify where the farming system may be intensified by the inclusion of a shortseason crop during the fallow period. Rice-fallow cropland areas are those areas where rice is grown during the kharif growing season (June–October), followed by a fallow durin...

In Washington, over fifty percent of the wheat produced under rainfed conditions receives less than 300 mm of annual precipitation. Hence, a winter wheat-summer fallow cropping system has been adopted to obtain adequate moisture for winter wheat production. Current tilled fallow systems are exposed to significant soil degradation from wind and water erosion. As a result, late-planted no-till fa...

The availability of Haber-Bosch nitrogen (N) has permitted agricultural intensification and increased the productive capacity of agroecosystems; however, approximately 50% of this applied fertilizer N is lost from agricultural landscapes. Extensive efforts have been devoted to improving the N use efficiency of these systems. Diversified crop rotations using cover crops to provide a variety of e...
