Imidazolinone-resistant (IR) wheat (Triticum aestivum L.) was released for commercial production in portions of the USA in 2002 and has provided growers with a new technology to selectively control winter annual grass weeds. Imidazolinone herbicides inhibit acetolactate synthase (ALS) in susceptible plants; however, IR wheat has an altered target site which confers resistance to these herbicide...

Abstract: Applications of remote sensing using unmanned aerial vehicle (UAV) in agriculture has proved to be an effective and efficient way of obtaining field information. In this study, we validated the feasibility of utilizing multi-temporal color images acquired from a low altitude UAV-camera system to monitor real-time wheat growth status and to map within-field spatial variations of wheat ...

performance, aid with weed and pest management, better utilize soil and water resources, and, in the case of Brassica oilseeds, provide benefits for pollinators. Growers have relatively few economically viable cool season crop options in California (USDA NASS 2012), but diversifying winter crop options may become more valuable if summer production of irrigated annual or short-term perennial spe...

Nitrogen fertilizer is commonly applied to winter wheat in the High Plains to achieve moderate to high yields. Typically, anhydrous N is applied in the summer or early fall with a tillage operation. Some growers apply liquid N in the spring if winter and spring moisture are high to take advantage of higher yielding condition. Phosphate fertilizer is less frequently used on winter wheat than N f...

Scientists working in areas that are (rightly or wrongly) socially contentious might benefit by perusing readers' comments lodged on online newspaper websites after the appearance of announcements in their fields. On many occasions, they would find not only approving sentiments but also a surprising degree of hostility. The recent announcement of draft sequence coverage of the wheat genome prov...

Abstract From 2012 through 2020, a survey of wheat stem sawfly, Cephus cinctus Norton, was conducted in (Triticum aestivum L.) fields Eastern Colorado. In 2013, results showed sawfly infestations concentrated the northern part state with only few highly infested sites, 38 94 sampled sites having any infestation (five which had >50% levels). By 2020 been found all eastern counties sampled...

This research project employed an interdisciplinary attempt to study agricultural climate information use, linking sociology of translation (actor-network theory) and actor analysis premises in a qualitative research design. The research method used case study approaches and purposively selected a sample consisting of wheat growers of the Fars province of Iran, who are known as contact farmers....
