Download or read book Spacing and Rates of Nitrogen For Corn written by C. E. Scarsbrook and published by . This book was released on 1966 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Close spacing and high rates of nitrogen are management practices that are essential for production of high yields of corn in Alabama. Since each of these practices affects value of the other, both must be followed for highest possible returns, as shown by results of experiments at several locations of Auburn University Agricultural Experiment Station System. Averages of data from 18 experiments show that 9-inch spacing in 42-inch rows (16,600 plants per acre) produced more corn than wider spacings tested. Since there is usually about 15 per cent loss of stand between planting and maturity, getting the correct population requires planting at 8 inches in 42-inch rows and at 9 inches in 36-inch rows. For most locations in Alabama, 90 to 120 pounds of nitrogen per acre in the recommemded rate, based on the experiments reported. In the Sand Mountain area, rates of 120 to 150 pounds are recommended. Choices of actual rate within the ranges suggested should be made on the basis of anticipated yield. When conditions are favorable for production to surpass 75 bushels per acre, the higher rates will usually be profitable.

Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted in 1965 and 1966 on a fertile Sharon silt loam near Elsberry. Missouri, to determine the maximum yield response of corn for different levels of plant population and now widths, using two hybrids. Adequate fertilizer and irrigation were applied as needed to limit the study to the above variabels. Analysis of corn leaf and whose-plant samples showed that plant nutrition was nor a variable. Adequate soil water was maintained so that the plants were nor under severe water stress after the seedling stage. Other climatic conditions such as cold, wer periods during the early growing season and above-average temperatures during silking and ear-shoot formation limited the yields to below the maximum potential for this area. It is believed, however, that the differences in yield response to the various treatments are representative. Average grain yields from the Pionner 321 hybrid corn were highest from the 24,000- and 20,000- plants populations and 30-inch row widths. The average yields for the 2 years was 159 bushels per acre both populations.(...).

This book was released on 2001 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: This experiment was conducted during the 1999 and 2000 growing seasons at the Iowa State University Sorenson Farm located southwest of Ames, Iowa and at the Iowa State University North Central Research and Demonstration Farm located south of Kanawha, Iowa. The experimental design for both locations was a randomized complete block with a split-split-split plot design and three replications of each treatment. Treatments included three planting dates, three hybrids, two row spacings, and two fertility regimes. Whole plot treatment was planting date and split plot treatments were hybrid, row spacing, and fertility regime. Significant difference was found between row spacing treatments for yield with the June planting dates in 1999 with 38-cm row spacing yielding more than 76-cm row spacing. Significant difference was not found between row spacing treatments for yield at the other planting dates in 1999 or in 2000. As planting date was delayed, weight kernel−1 decreased at both locations in both years. Starter fertilizer produced significantly higher yields in 1999, with a cold and wet spring, but not in 2000 with a warm and dry spring. Producers should rely on calendar date recommendations in determining optimum planting date. Planting dates between late April to early May should result in maximum yields in most years. Starter fertilizer may provide benefits during a cold and wet spring as well in situations of a low soil test for P or K.

This book was released on 1974 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two field corn experiments were conducted on a Woodburn silt loam soil near Corvallis, Oregon, in 1972-1973 to investigate the effects of certain soil management practices on the yield and performance of corn (Zea mays L.). Experiment I involved variables that included three corn row spacings (76, 114, and 152 cm) with annual ryegrass (Lolium multiflorum) interplanted at three different dates between the corn rows. Average dry matter corn yield of 17.6 m ton/ha obtained in the 76 cm spaced rows decreased by 16% as the row spacing increased to 114 cm. Increasing the row spacing from 114 to 152 cm did not affect corn yield. Corn yield was reduced when grass was interplanted in the widely spaced corn rows. A 35% corn plant yield decrease resulted when grass was planted on May 25 in the 152 cm wide corn rows as compared with the 76 cm row spacing. A further 15% reduction in corn yields occurred when ryegrass intercropped in the 152 cm rows was compared with yield from 76 cm rows which had no grass intercrop. Intercropping with ryegrass had no adverse effect on corn yield provided that such grasses were planted on July 24 or October 7 in the 76 cm spaced corn rows. Previous field history and the relatively high nitrogen taken up by the combined corn and grass crops suggested that the experimental area contained considerable residual soil nitrogen. Experiment II aimed at elucidating the effects of rate and method of applied nitrogen have on the yields from differently spaced corn. A 14% increase in dry matter yield of corn was obtained when row spacing was reduced from 91 to 61 cm. Moisture loss due to evaporation from the soil surface in the wide corn rows was higher than in the narrow spaced corn, Small dry matter corn yield increases were observed as nitrogen fertilizer rates increased from 140 to 196 Kg N/ha or from 196 to 252 Kg N/ha, respectively. The significant corn yield increase resulting from 252 Kg N/ha over the 140 Kg N/ha rates represented an 8% increase. No differences in corn yield were noted due to methods of nitrogen application.
