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.

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 Crop Production written by United States Crop Reporting Board and published by Forgotten Books. This book was released on 2018-09-10 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Crop Production: May 1, 1948 Wheat emerged from the winter in promising condition wherever there was suf ficient moisture last fall and seeding was completed on time. This favorable situz tion prevails in most of the States east of the Hississippi River, the Intermoun tain States and the Pacific Northwest, in all of which the spring moisture situa tion also has been quite favorable and winter losses were light.' However, in the large winter wheat area of the Great Plains, wheat lost some ground during April in the struggle to overcome the handicap of late seeding and underdevelopment caused by the persistent dryness at seeding time. Rains during April in this southwestern area were of some benefit, but they were not enough to overcome the accumulated deficiency of moisture, the crusted condition of the ground and the delayed growth of the wheat plants in much of that area. In a large area in Nebraska, central and western nansas, lahoma, Texas and New Mexico Wheat was seeded with insufficient moisture and seeding continued until very late. Although hopes for this late seeded acreage were lifted considerably by rains that came during winter months, much of this acreage did not emerge until Harch. Then it had to contend with a crusted surface and dry weather during April. Thpofigfidutthe main wheat belt of central and western Kansas, excepting counties bordering Colorado, much of the wheat was seeded in the dust and failed to emerge until late heavy March snow and beating rains later caused a crust to form on the surface of the ground which was not softened until near the end of April. Heavy abandonment of seeded acreage is evident in Kansas, the prin cipal cause of which is late development of the crop, which resulted in thin stands poor tillering, and weediness. In Nebraska prospects for late sown wheat that had not made much growth or had not fully emerged were reduced by the crusted and cracked surface, high winds and inadequate precipitation. Top soil was dry and both depth of subsoil moisture and degree of saturation are less than last year. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Weather Crops and Markets, Vol. 2: August 5, 1922 Conditions Mostly Favorable for Cotton - Wheat Too Far Advanced for Much Rust Damage: Beneficial rains were received during the week ending Aug. 1 in many Central Valley districts, but the rainfall Was of rather local character and many areas were still in need of moisture. The rainfall was especially beneficial for growing crops in Iowa, much of South Dakota, portions of Kansas, and parts of the Ohio Valley States. Vegetation was improved also in the northwestern Plains area and in many sections of the central Rocky Mountain States.

Available in PDF, EPUB and Kindle. Book excerpt: "To support his theory, Cunfer looks at the entire Great Plains (450 counties in ten states), tapping historical agricultural census data paired with GIS mapping to illuminate land use on the Great Plains over 130 years. Coupled with several community and family case studies, this database allows Cunfer to reassess the interaction between farmers and nature in the Great Plains agricultural landscape."--BOOK JACKET.
