Abstract:
... Some producers in the inland Pacific Northwest (PNW) are interested in diversifying the traditional 2-yr sequence of winter wheat (Triticum aestivum L.) (WW)–summer fallow (SF) with oilseed crops to capture break crop effects. The objective of this study was to compare production costs and economic returns of 2-yr sequences with those of intensified 3-yr sequences at a low-precipitation (<300 mm) ...

However, this crop, when developed in the field, is forced to compete with weeds, which inevitably leads to a decrease in yield. The relationship between clogging, weather and climatic conditions and crop yields has been observed. How ...
