Eight years of annual no-till cropping in Washington’s winter wheat-summer fallow region
The tillage-based winter wheat (Triticum aestivum L.)-summer fallow (WW-SF) cropping system has dominated dryland farming in the Pacific Northwest USA for 125 years. We conducted a large-scale multidisciplinary 8-year study of annual (i.e., no summer fallow) no-till cropping systems as an alternative to WW-SF. Soft white and hard white classes of winter and spring wheat, spring barley (Hordeum ...

in order to adapt the results of previous researches on annual forage legumes in zanjan province to cold regions condition of iran, yield and quality characters of two outstanding species namely grass pea (lathyrus sativus l.) and common vetch (vicia sativa l.) were evaluated in summer fallow cultivation condition for one year in 28 locations over 11 provinces of the country. in the variance an...
متن کاملInteractions among leguminous trees, crops and weeds in a no-till alley cropping system
Trees improve the soil quality and their rapid growth in the tropics make agroforestry systems potentially effective for establishing low-input agricultural systems in this region. This study assessed the effects of the biophysical interactions among leguminous trees, weeds, cotton and maize in an alley cropping system. The experiment comprised six treatments: Clitoria + Gliricidia; Acacia ...

When averaged across the three growing seasons of the study, regression analyses indicated that 25R47 had maximum yield at ~1,320,000 seeds/acre, close to the recommended rate of 1,400,000 seeds/acre (Table 1). In contrast, 25R62 had a maximum yield at ~ 1,030,000 seeds/acre, about 400,000 seeds/acre less than the current recommended rate (Table 1). Furthermore, this variety did not respond to ...
متن کاملSimulated yield and profitability of five potential crops for intensifying the dryland wheat-fallow production system
Greater precipitation use efficiency (PUE) and economic returns by increasing cropping frequency through the addition of summer crops to the dryland winter wheat-fallow (WF) cropping system have been reported in the semiarid Central Great Plains of USA. However, due to the highly variable nature of precipitation and uncertain water availability, selection of a crop with assured positive net ret...
