Available in PDF, EPUB and Kindle. Book excerpt: Examining the interaction between population and corn yield is important because the challenge of feeding the world is real. Projections show the world population is increasing and expected to reach over 9 billion people by around 2050. Expanding global urbanization drives the need to increase corn yield on current land and needs to occur to meet global population growth. Previous studies on corn yield increases conclude that ear size is limited and increasing corn plants per acre is important to increasing yield potential. This study used Answerplot data to analyze the effect of increasing plant population on corn yield in 2009. There are over 150 Answerplots across the cornbelt. The weather of 2009 proved to be a challenging year in certain regions of the cornbelt. Record rainfall, and below normal temperature had an influence on corn yield. A total of 4,180 observations from Answerplot were used from across the nation to analyze the relationship between corn yield and plant population. Multiple regression models were estimated and found that in 2009, an increase in plant population from 30,000 to 40,000 plants per acre resulted in an 8.5 bushel per acre increase. This result was robust for various econometric models. Economically, the cost per acre for current seed for this increase in population is about $38.87 per acre. At a corn price greater than $4.58 per bushel, increasing plant population would have made economic sense for 2009.

Available in PDF, EPUB and Kindle. Book excerpt: Early planting is one technique to avoid or reduce heat and drought problems that negatively affecting grain crop production. If producers adopt early planting, cold temperatures may negatively affect corn yield. It is important to select hybrids that are suited for planting earlier in the southern United States. Experiments were conducted by imposing low temperatures during seed germination. Twenty commercially available corn hybrids were evaluated for seed germination and root elongation. The first objective was: 1) To determine if some hybrids germinate better at cooler temperatures than others; and 2) Determine variation in root elongation at cold temperatures among commercially available hybrids. Corn hybrids varied significantly for seed germination and root traits under cold temperatures. Some hybrids have significantly surpassed others in seed germination traits, and they germinated earlier as well having longer radicle length. Also, there were significant differences across temperatures for all traits measured. A second objective was: 1) To quantify the effects of cold temperature on seed germination rate; 2) To evaluate the effects of different cold temperatures on seed germination behavior of corn hybrids under laboratory conditions to determine how fast they germinated; and 3) To classify hybrids for response to cold temperature using cumulative seed germination. The results showed that standard germination performance occurred at 10oC for all hybrids, but these hybrids performed well under other cold treatments (7.2°C and 8.6° C). There were no big differences between early hybrids 93 to 105 RM (Relative Maturity) and full season 115 to 120 RM in germination % and rate in both experiments, so that means that it pretty much depends on the hybrid. Therefore, the temperature had a major influence on seed germination parameters. These findings are useful for hybrid selection with respect to cool soil temperature conditions during early planting.
