New agricultural publications from Nebraska Extension include ones on fungicides for soybeans, a primer on cover crops, on-farm research results, agriculture in the Nebraska Panhandle, and ones on estimating soil water deep percolation or run-off.
North Platte River water operations and deliveries are expected to be normal for the 2017 growing season with an expected demand of 1.1 million acre-feet, according to a US Bureau of Reclamation forecast presented at the University of Nebraska Panhandle Research and Extension Center in Scottsbluff April 19.
I usually start reporting on river flows and water reservoirs affecting western Nebraska in early May, but with recent national news about the spillway at the Oroville Dam in California, you may be wondering about the status of snowpack water content and the reservoir levels along the North Platte River in Wyoming.
Both corn and soybean are susceptible to extreme heat (and water) stress during early vegetative stages as well as later critical growth stages (pollination for corn and flowering for soybean). Extreme heat stress can reduce plant photosynthetic and transpiration efficiencies and negatively impact plant root development, which collectively can negatively impact yield. The author recommends that during an extended heat wave (air temperature equal to or greater than 90 F for 7-10 days), applying 0.25-0.40 inch of water can be very beneficial.
Nebraska Extension's new Agricultural Water Management Guide, an online, interactive resource, offers information, videos, and illustrations about various types of irrigation, their advantages and disadvantages, technologies and strategies.
