Pratylenchus 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 کاملNitrogen Fertilizer Management in Dryland Wheat Cropping Systems
Wheat is the most widely cultivated food crop in the world, which provides nutrition to most of the world population and is well adapted to a wide range of environmental conditions. Timely and efficient rates of nitrogen (N) application are vital for increasing wheat grain yield and protein content, and maintaining environmental sustainability. The goal of this study was to investigate the effe...
متن کاملInteractions between Heterodera avenae and Pratylenchus neglectus on Wheat.
In a long-term field experiment, differential population densities of Heterodera avenae were produced by frequent cropping with resistant (cv. Panema) or susceptible (cv. Peniarth) oat. The two oat cultivars were equally good hosts of Pratylenchus neglectus in a glass house experiment with field soil. On wheat crops grown after oats in field experiments, P. neglectus population densities in roo...

متن کاملLong-term no-till: A major driver of fungal communities in dryland wheat cropping systems
In the dryland Pacific Northwest wheat cropping systems, no-till is becoming more prevalent as a way to reduce soil erosion and fuel inputs. Tillage can have a profound effect on microbial communities and soilborne fungal pathogens, such as Rhizoctonia. We compared the fungal communities in long-term no-till (NT) plots adjacent to conventionally tilled (CT) plots, over three years at two locati...
