In Wake Of Drought, CENTRE HALL (Centre Co.) Centre County com grower Wade Wolfe is just beginning to pick com, so he is not sure how much of an effect this year’s late season drought will have on yields. Both he and his father, Glenn Wolfe, say that in the 45 years the family has been on this farm, they have seen worse years than this. So far the test weights are down, said Wade, because of PENNSYLVANIA MASTER ORN GROWERS ASSOCIATION Associate Professor t&t' jH tween OBSERVATIONS FROM ANOTHER STRANGE YEAR The 1995 growing season was, to say the least, a different com growing experience than many of us have experienced in the recent past. Seed' Treatments May ANDY ANDREWS Lancaster Farming Staff LANDISVILLE (Lancaster Co.) Untreated seed and an unusually mild winter this year may have severely affected com stand and possibly overall harvest, according to a Penn State researcher. At this year’s Weed Field Day held in July at the universi ty’s Southeast Research Labor atory in Landisville, com plants showed evidence of a lack of seed treatment problems with emergence in spots, com height variability, and overall population decrease because of overwintering insects and disease. According to Greg Roth, associate professor of agro nomy at Penn State, the unevenness and spotty growth could be blamed on “a flush of soil critters due to the open and relatively warm winter we had.” The uneven height could ho a secondary symptom, he said. Fields inspected throughout the state showed similar prob lems with brown discoloration .In the root system from wire- w °nns, seed com infestation, and seed fungus. All these problems could pve been reduced with a PENNSYLVANIA HASTEN CONN GNOWENS ASSOC., INC. low moisture, reducing the fullness of the kernels. The average test weight so far has been 52 pounds/bushcl it should be around 56 to avoid being docked when selling the com. Another problem this year is a big variation in kernel mois ture. Wade said the monitor on his combine indicated a range of from 15 to 40 percent in one field with higher moisture levels in spots with deeper soil. Foe many of us it was a learn ing experience which is what keeps this business interesting. Let’s examine a few of the challenges that occurred during the last half of the 1995 com production season in Pennsyl vania and discuss the lessons (Turn to Poflo S) “three-way” scedbox treat ment, combining a fungicide, insecticide, and a chemical Greg Roth, right, shows heslthy root growth of corn to Tom Oyler, Gettysburg, at this year’s Ag Progress Days. Corn Talk, Lancaster Farming, Saturday, October 14, 1995 Wolfes Worry About Com Test Weights When the kernel moisture is higher or lower than what the combine is set for before harvesting, the kernels are bro ken up, cutting down yields and increasing spoilage in stor age bins if moisture is too high. Glenn estimates a 25-50 per cent drop in com yields this year, as the ears are half the normal length, and there are some barren stalks. Later com varieties didn’t pollinate, he said. Also, if they get high winds before the corn is harvested, the unusually tall stalks, which are brittle from the drought and are carrying the ears four feet off the ground, will go down. Another harvesting problem resulted from sap leaving the stalks too quickly, which meant that a lot of com cut for silage was too dry. Wade tried adding water to the silage as it was being unloaded, but that didn’t work because the silage was so dry that they couldn’t add water fast enough to do much good. But there is some good news about this year’s com. Wade is pleased about the quality of the yellow coloration in the com.

Com emergence should have topped 21,000 plants per acre. However, only 15,000-16,000 plants emerged, said Roth, “a pretty significant drop in population.” Of the problems reported throughout the state, many were a result of the “second wave” of com planted, in the May 1-May 10 timeframe. Not every field was affected. Nonemergent com should not exceed 10 percent of the total planted. But in many cases, nonemeigent totals approached 20 percent of total planted. In some cases, Roth has seen fields drop down to 15,000 plants per acre or less. Some fields needed to be replanted.

Researchers at Cornell have done more research than Penn State on the use of seed treat ments, and “they find that the use of these ‘three-way’ pro ducts gives you the most broad spectrum control” of problems. Roth said that Penn State will inspect and monitor fields to see if there arc some direct ben efits to using the seedbox treat ments. Cost equals about $2 per acre.
