Book excerpt: Excerpt from The Relations Between Crop Yields and Precipitation in the Great Plains Area, Vol. 1: Crop Rotations and Tillage Methods The cost of the maintenance of a practical summer fallow is one-half the acre cost of producing a crop of wheat, oats, Or corn. These relative values are therefore used in the following comparisons of crop rotations. As an example of one method of studying the theory and practice of crop rotation and tillage371 methods based upon these investigations covering 228 crop years, the continuous-cropping series, the aitel nate-fallow series, and rotations 1 to 9, inclusive, have been selected. They include 33 crops and 6 fallows each year at each of 16 field stations for an average period of 14% years, a total of plots. The rotations are simple 3-year rotations, and they are so arranged as to facilitate the comparison of different crop sequences and tillage methods.

Download or read book The Relations Between Crop Yields and Precipitation in the Great Plains Area Classic Reprint written by Ellery Channing Chilcott and published by Forgotten Books. This book was released on 2018-08-10 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Relations Between Crop Yields and Precipitation in the Great Plains Area To facilitate comparisons of these factors they are expressed diagrammatically, the perpendicular line representing the respective means and the horizontal lines the deviations from the means in percentages of the respective means. Deviations from the means are represented by extensions, to the right for those above the mean and to the left for those below. The relative lengths of these extensions are proportional to the per centages of deviation. If directly proportional rela tions existed between the crop yields and the precipita tions here represented, these extensions, if any, would be all in the same direction and to the same extent for any one year at any one station. That no such pro portional relations exist between either seasonal or annual precipitation and crop yields is obvious from an examination of these diagrams. Still more con elusive are the facts that the mean percentage devia tions for all of the 23 stations for the periods during which these investigations have been conducted, an aggregate of 303 years, are as follows: Seasonal precipitation, from 69 above to 49 below, a range of 118 per cent; annual precipitation from 49 above to 38 below, a range of 87 per cent. For crop yields the deviations are from 171 above to 99 below, a range of 270 per cent, which IS more than twice as great for crop yields as for seasonal precipitation and about three times as great as for annual precipitation.
