Corn Meeting on Wednesday

Posted by romeethredge on November 23, 2015

We will be having our Field Corn production meeting early this year. We will have it on Wednesday,  Dec 2 at Noon at the Lions Hall in Donalsonville. Dr. Dewey Lee and Dr. Eric Prostko, UGA Extension Scientists,  will be here to talk about Corn production and weed management.  We look forward to seeing you there.


The 2015 Corn production Guide can be accessed here. Here’s an excerpt from it.

Corn production in Georgia has remained relatively steady in the past decade due to limited opportunities for profit and increased risks from higher production costs. Corn acreage in the 1970s averaged 1.64 million acres in Georgia, however, it declined almost 50 per cent in the 1980s to 0.86 million acres due to poor prices and extended periods of drought and further still during the 1990’s. Since then, acreage has stabilized averaging 380,000 acres in recent years. It is predicted that acreage will drop slightly in 2015 from 2014 due to lower corn prices and increasing cost of inputs.

 Plant corn as soon as temperature and moisture become favorable for seed germination and seedling growth. Soil temperature in the seed zone should be 55 F or greater before planting. Corn seed will sprout slowly at 55 F while germination is prompt at 60 F. Delay planting if  cold weather drops soil temperatures below 55 F at the two-inch level. However, if soil temperatures are 55 F and higher, and projections are for a warming trend, corn planting should proceed.

Extremely early planting introduces a risk to frost or freeze damage and subsequent loss of stands, however, producers yields are greatest with early planting. Usually, as long as the growing point is below ground level, corn can withstand a severe frost or freezing damage without yield reduction. It is best therefore to monitor soil conditions and weather if your desire is to plant as early as possible.

Generally it takes corn seed 7 to 12 days to emerge when planted in soils there are 55 F. Early planted corn out-yields late planted corn. Depending on your location, planting dates may range from early March in south Georgia to mid-May in north Georgia. Early planting helps avoid periods of low rainfall and excessive heat during pollination, both of which lead to internal water stress during critical periods of corn development. Early planting is essential when double cropping soybeans, grain sorghum, millet or vegetables following irrigated corn. As planting is delayed into the summer, corn yields decline. In general, yields decline at ¾ a bushel per day rising to about 2.5 bushels per day.
