Cool nights slowing bermudagrass growth
John Jennings, Professor – Extension Forages
This spring has been full of variable weather conditions, mostly unfavorable for bermudagrass growth. The warm winter fueled expectations of an early spring and quick forage growth. The 15-day forecast (for late May) shows warming night temperatures in the 60+ degree range for central and south Arkansas, but night temperatures for the higher elevations in north Arkansas are still forecast to be in the 50’s with a few nights forecast to be in the upper 40’s. Bermudagrass is a warm season grass that needs warm day and warm night temperatures. It begins greening up after warm days, but never really produces significant growth until night temperatures are 60 degrees F for about a week or more. The grass will try to grow on warm days, but cool night shuts down the internal “machinery” which basically negates any sustained growth. When a string of warm nights occurs, the grass is ready to begin sustained growth as spring temperatures continue to warm till summer. Fertilizing bermudagrass before night temperatures have reached the 60 degree mark results in lower fertilizer efficiency. The grass may green up but other cool season grasses and weeds will out-compete the languishing bermudagrass for the nutrients. For mixed pastures with fescue and bermudagrass, the fescue will continue to grow through this cool weather and the bermuda will finally catch up as summer temperatures arrive. Remember to soil test to get fertilizer recommendations especially for hay production. Pasture fertilizer recommendations are generally much lower than for hay due to recycling of nutrients. In recent years, many hay producers have neglected to apply sufficient potassium fertilizer for hay production and bermudagrass stands have thinned significantly as a result. Bermudagrass hay fertilization recommendations are designated by production level so requesting recommendations for the desired production level at the time of soil sample submission will help you get the optimum recommendations. For most producers, hay yield levels of either 2 or 4 tons per acre are sufficient for the soil and environment. In most cases, yield levels of 6 tons per acre would be on the high end for dryland hay production and yield levels of 8 tons per acre are usually under irrigation or exceptional growing conditions. Notes at the bottom of the soil test report provide recommendations on how to split the total fertilizer recommendation for season-long production.

The Boone County Conservation District was organized as it is now constituted (all of Boone County, Arkansas) on May 12, 1958. Previously, the District had been in part a portion of Crooked Creek Soil Conservation District which was organized January 7, 1938, and Kings River-Long Creek Soil Conservation District organized July 24, 1939.
The purpose of the District is to assist land owners and operators plan and carry out a program for the conservation, efficient and economical use of land, water, and related natural resources.
