Corn plot results releasedBy David G. Hallauer Meadowlark District Extension Agent, crops and soils/horticulture Kansas The Meadowlark Extension District Irrigated Corn Plot at Grantville wasn't irrigated this year--at least by center pivot. Mother Nature took care of all of the crop's moisture needs. The results from this year's plot (the only variety plot harvested for yield in 2009) is as follows, in planted order: Golden Harvest H-9145--180.4; DeKalb DK C63-42--193.8; Triumph 7514X--189.6; Taylor 1940 VT3--188.5; NC+ 4582 VT3--178.3; Ag Venture AV 8036 V3R--191.7; Midland 779 BtCCR--190.5; Pfister 3356 VT3--191.3; Triumph 1536H--180.4; Golden Harvest H-9127--194.5; DeKalb DK C61-69--196.4; Midland 7A58BRW--192.9; Ag Venture R8626 VBW--203.2; NC+ 6082 VT3--179.2; Taylor 1944--185.7; Pfister 2756--192.6. The plot average was 192.2 bushels/acre. Yields were corrected for check strips and weigh wagon differences. Data should be used in conjunction with plot results from your local dealer and the Kansas Crop Performance Tests. Special thanks to Rod Bigham and Randy Read for harvest coordination and supply of weigh wagons. Corn population results--Domann Farms One of the strip trials we conducted this year in the Meadowlark Extension District dealt with corn population. In this space next week, I'll share the interaction that a fixed ear/flex ear comparison had on population, but this week, we'll stick to population only. In one of two local trials, yield was maximized at the ends of our population spectrums (24,000 and 34,000 seeds/acre) with the 26,000, 28,000, 30,000, and 32,000 seeds/acre populations slightly lower. Keep in mind, however that the yield range was 167.6 to 174.1 bushels per acre, meaning the differences were slight and doubtfully significant. Essentially, population meant little difference to yield in this single trial. Results from the other corn population trial will be available soon. Christmas tree selection and care It's the most wonderful time, of the year--unless of course you get a Christmas tree that all the needles fall off of or it dries up and turns brown. If an artificial tree is your choice, I can't help you. If a real tree is in your future, however, consider these helpful tips to make sure the tree you select isn't too far gone--needles are a dull, grayish- green color, needles fail to ooze pitch when broken apart and squeezed, needles feel stiff and brittle; needles pull off tree easily. After you've made sure you meet all these requirements, you can cut or select a pre-cut tree to take home. When home, recut the trunk about one inch above the original cut to open up clogged, water-conducting tissues. Immediately place the trunk in warm water and locate the tree in as cool a spot as possible (avoid areas near fireplaces, wood-burning stoves, heat ducts and television sets as the heat will result in excess water loss and create a potential fire hazard). Always keep the reservoir full. If you don't, you'll have to recut the exposed trunk. Thinking of a 'home remedy' to keep the tree 'green'? Water really is your best bet. Adding aspirins, copper pennies, soda pop, sugar and bleach to the water reservoir have not been shown to prolong the life of a tree.
