1. Four R Nitrogen management for cotton. MU-FDRC research update.

Cotton is a much different crop than corn.  In addition to the dicot vs. monocot difference, cotton is a perennial plant cultivated as an annual crop.  A cotton crop must be “encouraged” to produce fruit and hence lint in this production system.  Input management, including nitrogen fertilizers, are central to modern cotton production. Adequate nitrogen must be available to a cotton crop during the critical flowering period.  In Missouri this is from mid-May to... D. Dunn

2. Potassium Effects on Yield, Grain Quality, Lodging, and Stalk Strength in Rice

Missouri has a long history of rice production, going back to 1910 when the crop was first grown in the northeast region of the state. From this 40-acre start, rice acreage has increased steadily over the years to over 180,000 acres currently. The statewide average yield was 110 bu/A in 1997 and increased to over 156 bu/A in 2015. Traditionally, nitrogen (N) management has been given top priority by farmers. But with increased yields and rotations with soybeans, K fertility is increasingly being... D. Dunn, G. Stevens
