Book Effect of Soil Salinity  Fertilization  Water Table Depth  and Runoff Control on Production of Nonirrigated Grain Sorghum in the Lower Rio Grande Valley

Download or read book Effect of Soil Salinity Fertilization Water Table Depth and Runoff Control on Production of Nonirrigated Grain Sorghum in the Lower Rio Grande Valley written by Leon Lyles and published by . This book was released on 1965 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of a 3-year study show no statistically significant differences in grain yields among six fertilizer treatment of nonirrigated grain sorghum. Apparently nutrient reserves are adequate for maximum production under existing soil salinity and rainfall conditions. Grain sorghum yields were related to the underground water table depth at seeding to fallow season rainfall and to the soluble salt concentration in the 0- to 3-foot soil depth. Water table depths of 3.35, 5,20 and 7.65 feet at seeding in 1961, 1962 and 1963, respectively, were associated with average grain yields of 3,627, 2,672 and 1,556 pounds per acre. It was determined that a 1-mmbo-per-centimeter increase in soil salinity at the 2- to 3-foot depth resulted in an average decrease of 180 pounds of grain per acre within the -5- to 11-mmhos-per-centimeter range of salt levels exhibited by the test site. Runoff control did not significantly affect yields any year. Absence of timely runoff, high evaptranspiration between crop season, and a high water table that equalizes soil moisture storage apparently explains tha lack of yield response to runoff control.

Book Masters Theses in the Pure and Applied Sciences

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer. This book was released on 1976 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis· seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac· tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 20 (thesis year 1975) a total of 10,374 theses titles from 28 Canadian and 239 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 20 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.

Download or read book Sorghum Science written by R. K. Maiti and published by . This book was released on 1996 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sorghum is one of the five important cereal crops of the world and is used by millions in the semi-arid tropics and also as animal feed in many developed countries. The sorghum grain has excellent yields in the semi-arid tropics under several biotic and abiotic constraints. A good knowledge of sorghum plants and their mechanisms of adaptation in harsh environments will help in the formulation of efficient breeding programmes.
