On-Farm Corn and Soybean Planter Demonstration Trials
Introduction Corn and soybean planting is one of the most critical operations of the season. Operating the planter with the proper soil conditions for proper placement of the seed to obtain the correct seed-soil contact is important to optimize yields and reduce problems later in the season with plant and root growth. As corn and soybean seed prices continue to rise, and grain prices fall, it i...
متن کاملSelecting Corn Hybrids
Corn is physiologically mature when kernels reach maximum dry weight and are safe from frost. All milky fluid disappears from the kernel, and the black layer, a dark layer of cells, forms near the tip of mature kernels. Most hybrids adapted to Wisconsin reach this stage when kernel moisture decreases to 30–32%, but it may not occur until moisture content decreases to 28% for some early hybrids....
متن کاملRanking Corn Silage Hybrids
Corn hybrids for silage vary in yield and several quality traits that affect farm profitability, which is the prime criterion on which hybrids should be ranked. The partial budget approach is the only way to rank corn hybrids for silage for individual farms according to their effects on farm profits. Partial budgets consider only those costs and returns that change in response to the corn hybri...
متن کاملForage Yield and Silage Quality of Dual-Purpose Corn Hybrids in Two Levels of Urea Fertigation
The experiment was completed to evaluate the responses of forage yield and silage quality of dual-purpose corn hybrids to urea fertigation. For this purpose, two studies were conducted each as a split plot experiment based on a randomized complete block design with three replications at two locations in research farms of College of Agriculture, Isfahan University of Technology, Isfahan, Iran, i...
متن کاملAdaptedness and Heterosis in Corn and Mule Hybrids
The origin of U.S. Corn Belt corn (Zea mays L.), heterotic groups, and heterotic patterns becomes less obvious with more cycles of breeding. Heterosis is poorly understood; simple curiosity cries out for more information. I endeavor to shed light on the effect of adaptedness and heterosis on U.S. Corn Belt corn. I relate pertinent happenings in the phenomenal increase in U.S. corn production. I...
