“…Peterson and Westfall (2004) found that intensification of cropping systems increased net return to producers in eastern Colorado by 25 to 45% compared with wheatfallow. Intensified dryland cropping systems have also increased potentially active surface soil organic C and N , effectively controlled winter annual grass weeds in winter wheat (Daugovish et al, 1999), and reduced yield loss in wheat resulting from soilborne disease (Krupinsky et al, 2002).…”

Winter wheat (Triticum aestivum L.) is the foundation of dryland cropping systems in the Central Great Plains. The objective of this study was to quantify the effects of four short‐season spring‐planted crops used to replace summer fallow on the subsequent winter wheat crop. Wheat was seeded into four crop stubbles [spring triticale (×Triticosecale Wittmack), dry pea (Pisum sativum L.), foxtail millet (Setaria italica L. Beauv.), and proso millet (Panicum miliaceum L.)] at sites near Akron, CO, and Sidney, NE, in the fall of 2004 and 2005. These summer fallow replacement crops were planted into silt loam soils at three different soil water levels at planting (low, medium, and high). Winter wheat water use was 3.6 cm greater, and grain yield was 662 kg ha−1 greater in the high water treatment compared with the low water treatment averaged across all sites and years. Winter wheat used an average of 4.3 cm more water following early planted summer crops (triticale and dry pea) than after late planted summer crops (foxtail and proso millet), but this increased water use did not consistently translate into increased grain yield as a result of terminal drought at Sidney in 2006. The high water treatment always had a positive net return. The high cost of pea seed ($3.30 kg−1, USD) strongly reduced profitability. The flexible summer fallow cropping system appears to be most applicable when using short‐duration summer annual forage crops such as triticale and foxtail millet.

“…(b) Crop populations Daugovish et al (1999) studied the long-term effects of two-and three-year rotations in Nebraska for the control of downy brome (Bromus tectorum L.), jointed goatgrass (Aegilops cylindrica Host) and feral rye (Secale spp.). The most profitable of all the different rotations was a three-year one of winter wheat, proso millet (crop) and fallow.…”

(Poaceae), has been a crop in Asia and Europe for 10 000 years and for over 300 years in Canada, where it is grown for grain, rescue crops, birdseed, forage, and recently for swath grazing. Crop-like biotypes have escaped from cultivation throughout Canada, but these infestations were generally temporary. Probably the first persistent, weedy biotype in Canada (Quebec) has large, dormant, dark red seeds. Its eradication has been attempted for many years. In the 1970s, a worse problem, a black-seeded biotype with many weedy attributes, including shattering as seeds ripen and strongly dormant seeds distasteful to many birds, spread across southern Ontario and became labelled as noxious. Concurrently, it was described as the worst weed in the US Corn Belt. In the 1980s, Canadian studies revealed infestations of other weedy biotypes, differing in seed colour and other attributes. Panicum miliaceum is an extremely variable species world-wide. Since the late 1990s, weedy proso millet has declined dramatically after the adoption of newer herbicides, particularly glyphosate. This development may lead to increases in cultivated proso millet, especially where climate change favours short-season crops grown under drier conditions. Key words: weed biology, proso millet, Panicum miliaceum L., weed/crop, intraspecific variation, global distribution and history.Résumé : On cultive le millet, Panicum miliaceum L. (poacées), depuis 10 000 ans en Asie et en Europe et depuis plus de trois siècles au Canada pour ses graines, comme provende de secours, pour nourrir les oiseaux, pour son fourrage et, plus récemment, pour la paissance en andain. Des biotypes domestiqués sont redevenus sauvages un peu partout au Canada, mais les infestations restent le plus souvent temporaires. Le premier biotype envahissant persistant du Canada a probablement été observé au Québec. Il se caractérise par de grosses semences rouges dormantes. On s'est efforcé de l'éradiquer pendant de nombreuses années. Dans les années 1970, un biotype à graines noires, possédant de nombreuses caractéristiques d'une mauvaise herbe (notamment l'égrenage prématuré quand les semences parviennent à maturité et des graines à dormance prolongée que peu d'oiseaux aiment), a soulevé un problème plus épineux en se répandant dans le sud de l'Ontario. Ce biotype a été qualifié de nuisible avant de devenir la pire adventice dans la ceinture du maïs des États-Unis. Dans les années 1980, des études canadiennes ont révélé l'existence de peuplements d'autres biotypes envahissants, aux semences de couleur différente et présentant d'autres caractères. Panicum miliaceum est une espèce extrêmement variable dans le monde. Depuis la fin des années 1990, les variétés envahissantes ont diminué de façon draconienne avec l'apparition de nouveaux herbicides, particulièrement le glyphosate. Ce développement pourrait déboucher su...

“…Diverse cropping systems can effectively control winter annual grasses in winter wheat systems, allowing wheat producers to deliver a higher-yielding crop that meets quality guidelines (Daugovish et al, 1999). Typically, producers make the move toward crop diversity to control weed or insect pests in the system more often than to increase profits.…”

Areawide Pest Management: Theory and Implementation

View full text Add to dashboard Cite

Areawide pest management (AWPM) programmes build upon past achievements in agricultural innovation, expanding the implementation of integrated pest management (IPM) practices to larger geographical scales. This chapter explores demonstration elements from the US Department of Agriculture, Agricultural Research Service's demonstration programme for cereal aphid (including the Russian wheat aphid, Diuraphis noxia, and the greenbug, Schizaphis graminum) AWPM. The control methods include the use of aphid-resistant cultivars, simplified field scouting, and diversified dryland cropping. The elements of the demonstration programme as agricultural innovations are explored. Potential adoption of these elements by wheat producers on the Great Plains and implications of the programme outcomes for other wheat-growing regions of the world are discussed. The chapter begins with a history of research on the adoption of agricultural innovations, which provides the context for evaluating the cereal aphid programme from the perspective of farmer adoption.
