Craig Dauphin County Agent Recently I read an article that dis cussed the affect that winter weather can have on alfalfa yields the following spring. The work upon which the article was based was con ducted at Michigan State Univer sity. The authors of the study note that injury to alfalfa can be caused by many factors. Among these factors are temperature fluctuations, lack of snow cover, and the persistence of Used Mower Conditioners From Hoober 59,900 817722 OH 149012'Mower Cond S26JBOO C 31455 OH 8330 Mower Cond . 553000 A 23206 NM 415 Mower Cond .. s4#3o A 23226 NH 499 Mower Cond . .

In addition, the weather conditions in the preceding fall and the following spring can also impact the winter survival of the alfalfa stand. Fluctuating temperatures with highs in the 40- to 60-degree range during winter can cause plants to break dormancy and initiate growth too early for normal spring develop ment. Snow cover is usually benefi cial from the stand point of temperature moderation at the crown and root zone and to protect 4755 Big Square Baler Solid construction, reduced labor and timesaving efficiency are all part of the Hesston large bale system that was introduced over 20 years ago These balers are built to last with features such as hydraulic density control, easy accessed and well protected drives and three-joint equal-angle drive line that permits quiet operation during turns. >• Requires as little as 90 PTO Horsepower >• Bales Measure 31 5” wide by 34 4" High by up to 98” in length >• Bales weigh up to 1,000 pounds in dry hay and 1,500 in high-moisture hay >• Designed to haul three wide and three high for maximum truck payloads 1340 Pull-Type Disc Mower Conditioner Hesston mower conditioners are known for delivering clean, fast cuts in the field and being able to work in tough conditions These machines were the first mower conditioners that allow you to cut on either side of the tractor, cut square corners or maneuver around field obstacles with a disc cutterbed machine >■ Eight Cutting Discs ► Twelve Foot Cutting Width ► Center-Pivot Maneuverability >• 3 Point Swivel Hitch Option ► Rubber-On-Steel or Steel-On-Steel Conditioning Rolls 8550 Self-Propelled Windrower These self-propelled wmdrowers are equipped with a 152 HP Cummins Engine, luxury cab and an 8070 Rotary Header 8070 Rotary Header Features: ► 10 Discs ► 2 Knives per Disc ► 15’ 3" Cutting Width >• Spur Gear Cutterbed Design ► 110" Conditioning Rolls Hoober Service Hoober has 5 hay and forage specialists with the experience and knowledge to keep your equipment running strong all year long.

A rapid meltdown of snow, followed by cold tempera tures, can result in long-term ice sheeting. This can cause smother ing, as the roots must breathe over winter, or low temperatures can injure plants because ice has a poor insulating value verses snow cover or “dry” soil. Weather conditions during the fall hardening season have been identified as aiding or hurting winter survival. Long fall periods I AGCO 1 HESSTON with sunny but cool conditions favor winter hardening. Fall periods with cloudy conditions and warmer tem peratures tend to de crease plant hardening. In early spring, wide tem perature fluctua- tions are not desirable and usu ally contribute to plant injury. Ideal conditions would be a gradual warming of air and soil with increasing day length periods. In the Michigan study, the research ers measured first cut yields of alfalfa as they related to 12 weather variables. The researchers used data from moderately win terhardy alfalfa varieties managed in a four-cut system, last cut taken on Oct. 15. Yields were taken from variety trial plots in the second and third production seasons. Of ail the weather variables tested, winter temperature fluctuations and spring growing degree day accumu lation were the most important weather variable affecting first cutting yields. Fluctuations mea sured daily air tem peratures rising above and failing below 31 degrees with less than six inches of snow cover. A higher than av erage number of fluctuations in winter temperatures resulted in lower yields and increased spring growing degree days im proved yields. In this study, the mini mum daily winter temperature did not reduce first cut yields. 217
