Most know of the High Plains or Ogallala Aquifer, but what of Nebraska's seven secondary aquifers? This university guide, dedicated to the state's well-drillers, discusses various characteristics of each of the aquifers and includes overlay maps to show their location.
Several field trials were undertaken in 2017 to look at options for controlling herbicide-resistant kochia, Palmer amaranth, and waterhemp in dry bean, corn, and sugarbeet. In addition over 80 kochia, Palmer amaranth, and waterhemp plants were collected for testing of herbicide resistance. Of these 50% of kochia and 13% of Palmer amaranth plants tested were resistant to field rates of glyphosate. While options are limited in the Panhandle, pairing crop rotations with herbicide programs using PRE and layby treatments provided effective control of key weed species.

Soil testing and a disease index developed at the university's Panhandle Research and Extension Center can help growers identify rhizoctonia risk levels of fields before they're planted to sugar beets.
Learn from successful practitioners and explore new ideas for creating a more diverse and sustainable farm or ranch operation at this year's Western Sustainable Ag Crops and Livestock Conference. The conference will be December 16 in Sidney.
In the third year of its research on using chopped sugarbeets for livestock feed, university researchers are moving from using pregnant cows to weaned calves as their research subjects. Growing and finishing trials will be conducted with calves both receiving and not receiving sugarbeets as an energy source.
Corn harvest in the Panhandle has been progressing for several weeks now. Yields have been 80-100 bushels per acre on dryland and 160–220 bushels per acre irrigated. Dry bean harvest is almost done, but regular sugar beet harvest has slowed due to the wide fluctuation in temperatures.
