    Cool weekend temperatures have prompted some concern about possible injury to the wheat crop.

    The effect of cold weather depends on the wheat growth stage. Maximum resistance to cold weather occurs in December-February. As wheat greens-up, the plant becomes less tolerant of freezing

    When the winter is as mild as it was this past year, pathogens that would have otherwise been killed or at least suppressed by the cold temperatures end up surviving and getting an early start to infect our crops. With the exception of the rust fungi, most of the pathogens that cause leaf spots and blights and ear rots and molds have developed strategies to survive our usually harsh winters

    Modified relay intercropping of soybeans into wheat is a very versatile system across many row spacings. Over the past 17 years of intercropping at OSU Unger Farm, three rows spacings have been used. Ten inch spacing was used for the first 15 years, but this period also included three years of 15 inch work. The last two years, twin row wheat has been grown. The variations in row spacing show the flexibility of wheat to respond to various stresses. According to

    One of the questions that has come up repeatedly over the past year or so concerns the appropriate order of vertical tillage versus herbicide application in the spring. Two general principles guide our thinking on this issue: 1) if possible, foliar burndown herbicides should be applied to undisturbed weeds that are not partially or fully covered with soil; and 2) residual herbicides should left on the surface undisturbed by tillage (allowing rain to move herbicide into the soil)

    There are at least five growth scale systems developed worldwide for wheat, the one we often use is the Feekes scale. This scale uses a numbering system 1 through 11 with each number representative of a new growth event. Each number may be further divided by using decimals to further describe a

    This week’s installment of “The Big Data Confusion” highlights “Collection, Access and Control”. According to the Privacy and Security Principles for Farm Data, “an ATP’s collection, access and use of farm data should be granted only with the affirmative and explicit consent of the farmer. This process will be by contract agreements, whether signed or digital.” This particular principle is a
