Page 14—Corn Talk, Lancaster Farming, Saturday, October 10, 1998 Ag Progress Demonstrates Com Harvesting Equipment ROCKSPRING (Centre Co.) Kernel processing, fast and more efficient silage harvest ing, and even methods to get improved fresh market sweet com ears into the wagon were highlights of two Ag Progress demonstrations. During Ag Progress Days in August, a couple of companies introduced com silage harves ters to a crowd of several hundred visitors to the Rockspring research site. Afterward, one company put on a show of a sweet com pick er and demonstrated the tech nology to a crowd of about 45 vegetable growers and agri industry representatives. Lynn Hoffman, Penn State agronomist, provided informa tion about the com hybrid planted at the demonstration area and introduced two com silage harvesters. The harvesters included new com kernel processing technol ogy to allow improved ensiling, which creates better dry matter feed for livestock. The proces sor, in essence, crimps, cracks, and shreds the kernel to allow improved digestibility for animals. The com was planted on 30-inch rows no-tilled on May 15. The two harvesters demon strated to the crowd included one that uses a rotating blade and the other with a conven tional chopping silage head. The material was a couple of weeks early to ensile, noted Hoffman, because the com was at the milking stage with too high moisture in the com. If the com was planted in early May instead, the kernel breaking process could have been better demonstrated, he noted. Visitors were allowed to see how the com was chopped and loaded into wagons at the site.

The no-till plot was planted May 15 and the conventionally tilled plot was planted May 18, according to Tom Murphy, Lycoming County extension agent. For both plots, a preplant fertilizer with 400 pounds 34-0-0 was used. A sidedress ing of 100 pounds of 10-30-10 was also added. About 150 pounds per acre of nitrogen altogether were applied. In addition, several weed and insect control applications were used. The no-till plot was planted into rye stubble and hairy vetch. The same applications were applied. The com picker draws the stalk into an area that pinches the com and pulls it off, similar to how it is done by hand in the field. According to several grow ers, the challenge is coming up with a machine that can dif ferentiate between useful, marketable ears and those that won’t sell on the auction block or at the farm market. Varieties need to be planted, if using the picker, that mature at the same time. Also, according to an equip ment demonstrator, growers need to consider several factors before deciding to pay about $26,500 for the machine, including materials and labor cost and sweet com market prices, before deciding on the cost effectiveness of the picker compared to hand-picking. The growers had a chance to look into the wagon at the sweet com picked by the harvester. Many noted that the sweet com ear size was sufficient.
