Abstract Rotating cereal crops (e.g., wheat [ Triticum aestivum L.] with a 10‐ to 21‐mo summer fallow period [fallow]) is common farming practice in dryland (rainfed) agricultural regions. Fallow associated several challenges including low precipitation storage efficiency, depletion of soil organic carbon (SOC), loss fertility, little crop residue retention and erosion, few control options for ...

The cereal-based intensive cropping practices have posed the yield at a plateau and reduced energy use efficiency (EUE) of systems in Indo-genetic plains (IGPs). long-term experimentations with 4 diversified legumes cereal grassland fallow system were studied for >10 years representing different agro-ecological regions agricultural research farm, IAS, BHU-Varanasi, Uttar Pradesh IGPs to asse...

those methods as they have been used from the Canadian Prairie Provinces to the southern Great Plains of Successful dryland crop production in the semiarid Great Plains the United States and the resultant effects on system of North America must make efficient use of precipitation that is often limited and erratic in spatial and temporal distribution. The purpose WUE. Additionally, differences i...

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...

Dryland farming in the Mediterranean climate of the Pacific Northwest, USA supports extremely low earthworm populations under conventional tillage. Increases in earthworm populations are being observed in fields under no-till cropping systems. A 30+ year experiment with four tillage levels in a pea (Pisum sativum L.)-winter wheat (Triticum aestivum L.) rotation was evaluated for earthworm popul...

it is suggested that cultivars of wheat (triticum aestivum l.) with regulated growth and development would be able to produce higher yields under water-limited conditions, which is crucial in future food production. water use efficiency (wue) is worthy of exploration in this regard. in this study, the effects of nitrogen fertilizer levels (0, 40 and 80 kg nha-1) and a plant growth retardant (ch...

the erosion in dryland caused decrease in yield and soil quality, especially in slope land with conventional tillage. to investigate effect of tillage and planting methods in slope land on erosion and yield of dryland wheat, an experiment was conducted in 2007 at kermanshah province. the statistical design for this research was strip split plots in rcb (randomized complete blocks) with three re...

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...

Previously published research reported a “synergistic effect” of corn (Zea mays L.) on winter wheat (Triticum aestivum L.) and proso millet (Panicum miliaceum L.) water use efficiency (WUE) when corn (C) was the preceding crop for dryland cropping systems in the central Great Plains, i.e., less water was required to grow a unit of wheat (W) or proso millet (M) when corn was the preceding crop. ...
