Selecting 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 کاملAllometric relationship between some morpho-physiological characteristics of corn under different tillage systems and sowing dates
ABSTRACT- Field experiments were conducted to determine the relationship between plant leaf area as the dependent variable with leaves number, leaf dry weight, and total vegetative components dry weight and plant height as the independent variables. Treatments were two tillage systems (conventional and no-tillage) as main plots, and seven sowing dates (11 May, 18 May, 25 May, 1...
متن کاملCurrent Agronomic Reserch Related to Corn Silage
Predicting animal performance and relating it to improvements in corn silage quality whether from breeding or management is complex. In numerous studies, differences in fiber and digestibility translate into differences in animal performance. For example, researchers in Idaho have found that high quality corn silage (low fiber and high digestibility) produced $315 more beef per acre than low qu...
متن کاملAgronomic Responses of Corn Hybrids from Different Eras to Deficit and Adequate Levels of Water and Nitrogen
Triticum aestivum L.). These high application levels result in low N use efficiency (NUE), with estimates of Maintaining current high yields of corn (Zea mays L.) grown in NUE for world cereal grain production systems at only the USA poses an environmental threat due to continued overuse of 33% (Raun and Johnson, 1999). This represents a $15.9 water and N inputs. To reduce overreliance on input...
