Various factors such as delayed planting, early frost, drought or suppressed market prices may lead one to consider feeding soybeans to cattle. Soybeans can be fed to beef cattle as an energy and protein source. Depending upon the stage of development, soybeans will have varying degrees of feed value and a feed test for nutrient content is recommended.

Although soybeans are commonly grown as a grain crop, they can be grazed or harvested as either a hay or silage crop. This most commonly occurs when the grain potential of the soybean crop has been reduced by drought, hail damage, or early frost. A realistic forage yield expectation for drought stressed soybeans would be 1.5 to 2.0 tons of dry matter per acre. The objective of this article is to provide practical tips for successfully, grazing, conserving and feeding drought stressed soybeans.

In Kentucky, farmers grow soybeans in two common soybean production systems: full season and double crop. Farmers plant full season soybeans in the spring and harvest them that fall, so they have harvested one crop in one calendar year. Farmers plant double crop soybeans after wheat harvest in June. These soybeans are harvested later that fall, making them the second crop harvested in the same calendar year. Both systems are important to the overall production of soybean in Kentucky. Therefore, in 1980, an annual soybean yield contest was initiated in Kentucky to document the agronomic practices utilized by producers.

Understanding the biology of a weed is the first step in implementing an effective weed control program. This is especially true with Palmer amaranth (Amaranthus palmeri) and waterhemp (Amaranthus tuberculatus), as understanding their emergence patterns, competitiveness, adaptability, and seed production all need to be considered when developing a control program.

The double crop soybean system was pioneered in Kentucky. Traditionally, double crop soybean are planted in June following harvest of a small grain: wheat, barley, and in some cases cereal rye. Since the early 2000's, about 25% of the total soybean production in Kentucky has been double crop soybean. Many agronomic management strategies are similar between double crop soybean and full season soybean: soybean planted in the spring following corn from the previous year. However, there are certain management strategies that are important for double crop soybean, which not only increase yield potential but also offer opportunities to increase profitability.

The Kentucky Soybean Variety Performance Tests are conducted to provide an unbiased and objective estimate of the relative performance of soybean varieties commercially available in Kentucky. This information may be used by growers and seed producers to aid in selecting varieties that will give the highest total production in a specific situation. Soybean cultivars in the 2018 tests were entered by soybean growers, commercial companies, state and federal institutions. Forty soybean tests were planted in 2018 in Kentucky, at the eight test locations shown below. However, due to weed pressure, one location was discontinued.

Soybean variety selection is one of the most important and most difficult management decisions a producer must make each year. It takes careful identification of the problems and needs of the production system. When done properly it increases the chance the variety will reach its full yield potential while eliminating costs for unnecessary traits, resulting in highly profitable returns.

The soybean cyst nematode (Heterodera glycines, SCN) causes many millions of dollars worth of damage to Kentucky soybean fields each year. This occurs even though damage is mostly preventable and controls are inexpensive. This situation exists because a large number of soybean producers are unaware that cyst nematode is damaging their crops. In most cases soybean cyst nematode will cause significant yield reductions without producing any detectable symptoms in soybeans. When symptoms do occur, they are frequently thought to be associated with some other factor, such as soil compaction or low soil fertility.

The 2012 Soybean Management Verification Program (SoyMVP) enrolled 19 fields across Western Kentucky, providing ten direct comparisons between University of Kentucky recommendations and producers practices for soybean production. All fields were scouted weekly and recommendations were made on the university portion of the field based on established thresholds and observations from agronomic research. The objective of these comparisons is to validate university research and identify areas for more research.

Soybean cyst nematode (SCN) is the most serious disease pest of soybean in the United States (and Kentucky) and results in an estimated $1 billion in losses annually. SCN is a microscopic roundworm (Heterodera glycines) that feeds on root of soybean and reduces its capacity to absorb water and nutrients. Yield losses of 30% or more are common where SCN-susceptible soybean varieties are grown and SCN levels are high. SCN was first discovered in Kentucky in 1957 in Fulton County but is now found in every Kentucky county in which soybean is grown commercially.

Interest in the use of foliar fungicides for corn and soybean has expanded dramatically in the U.S. over the past few years, resulting in a major change in how these crops are being produced on many farms. Until recently, foliar fungicides for soybeans and corn were reserved for seed production fields to protect seed quality in very specific circumstances or for specialty crops. Applications for the purpose of protecting crop yield were rarely economical. However, the current trend in Kentucky, as well as many other corn/soybean producing states, is towards an increased use of foliar fungicides on these crops as a means of maximizing yields.

The Corn and Soybean Production Calendar was developed to help producers prioritize and schedule work events in a timely fashion on the farm. Weather events and equipment breakdowns rarely follow an organized schedule. However, if other practices within the farming operation are prioritized, perhaps a producer can better address the emergencies that will occur.

Soybean Cyst Nematode (SCN; Heterodera glycines) is the most widespread and significant pest of soybean in Kentucky. SCN is managed primarily by rotating fields to non-host crops (such as corn) and using SCN-resistant varieties. However, for a variety of reasons, producers occasionally desire to plant a SCN-susceptible variety.

Estimating soybean yield while the crop is still standing in the field can be a challenging procedure. Proceed with caution since variability in yield components such as plant population, seeds per pod, and seed size can all drastically affect the final yield. Yield estimates may be inaccurate when conducted before seed fill is complete, and assumptions of final pod number, seeds per pod, and seed size may not accurately reflect those values at maturity. The best estimate can be achieved at reproductive growth stage R6 (green pods with seeds that fill the pod cavity) or later.
