Simulated 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...
متن کاملDryland Wheat Grain Yield and Yield Components as Affected by Slope Direction and Residue Rates
Limited information is available on the effect of residues rates and slope direction on dryland wheat (Triticum aestivum L.) yield. This study was carried out to determine the effects of residues rates and tillage direction on grain yield and yield components of the Sardary wheat in a dryland region in Zanjan. Five wheat residues rates (0, 25, 50, 75 and 100% surface cover) were applied and i...
متن کاملPratylenchus neglectus Reduces Yield of Winter Wheat in Dryland Cropping Systems
Rainfed wheat (Triticum aestivum L.) is planted each year on 1.5 million ha in the low-precipitation region (150 to 300 mm) of north-central Oregon and south-central Washington. Precipitation occurs mostly (75%) from late autumn (October) to early spring (April) and the amount is highly variable from year to year. Winters are cold and intervals of frozen soil are common. Warm to hot days and co...
متن کاملYield Responses of Wheat to Mulching Practices in Dryland Farming on the Loess Plateau
Improving farming practices of soil and water conservation has profound effects on the yield of wheat (Triticum aestivum L.) in dryland farming regions of the Loess Plateau in China. Mulching has proven to be an effective practice to increase crop yield, and possibly contribute to replenishing groundwater. This evaluation study collected and analyzed the data of 1849 observations published in 3...
متن کاملEffect of Simulated Plow-sole on Water Uptake and Yield of Dryland Wheat
Yield of dryland crops grown on stored water is determined by water use from the profile which, in turn, is related to the extent of root proliferation in different layers. Plow-soles of high strength may retard root growth and adversely affect crop production. We determined the effect of initial profile water storage and soil compaction below the seed on the growth and the yield of dryland whe...
