Are you prepared for hay harvest? It is hard to believe with the persistent cool spring temperatures, but cool-season grass and legume hay harvest will likely begin a month from now.

n this episode, Shaun and Dan discuss how corn is no longer king in Indiana or the US after USDA’s Prospective Plantings report last week showed that farmers will plant more soybean acres than corn, and tips for those planting beans on beans.
Intensive study for more than 100 yr has resulted in a good understanding of corn’s (Zea mays L.) growth and development.
The number of 30-, 40-, and 60-ft wide (or larger) field crop planters across the U.S. Midwest is greater today than, say, 25 years ago.
Corn grain yields in the U.S. have steadily increased since the late 1930’s.
Perennial cool-season grass/legume pastures broke winter dormancy several weeks ago.
MULTI–YEAR SUMMARY OF CORN RESPONSE TO NITROGEN FERTILIZER This report summarizes corn yield response to fertilizer nitrogen (N) rate in field–scale trials conducted around the state of Indiana since 2006. These results are applicable to N management programs that use efficient methods and timings of N fertilizer application. The Agronomic Optimum N Rate (AONR) represents the total amount of fertilizer N (including starter N) required to maximize yield, but not necessarily profit. The AONR in these trials varied among regions of the state from about 211 to 254 lbs N / ac, depending partly on soil organic matter and soil drainage characteristics. At five Purdue Ag. Centers where we conducted paired trials of corn following soybean (corn/soy) and corn following corn (corn/corn) from 2007 to 2010, the average AONR for corn/corn was 44 lbs greater than for corn/soy while average corn/corn yields were 18 bu / ac less than the[Read More…]
Corn yield response to increasing nitrogen (N) rate follows the Law of Diminishing Returns – as higher and higher increments of N are applied, the increase in grain yield becomes smaller and smaller (Figure 1). Eventually, maximum yield occurs and applying more N does not increase yield any further.
Have you ever seeded a pasture or hay field and still have seed in the back of your pickup truck or trailer that was meant to be in the soil upon completion of the seeding?
