This book was released on 1975 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of growth of maize in relation to water in the soil-plant system was conducted in the field at Davis, California. The time course of root and aerial growth, and water uptake was investigated under conditions of a mild prolonged water stress, with emphasis of defining the soil and crop water status, photosynthesis and the generation of the yield and yield components also were studied. Hybrid maize was grown in deep alluvial soil with high mositure holding capacity. Three irrigation treatment were: a) Weekly 5-cm irrigation starting 21 days after planting (I treatment); b) No irrigation (NI treatment); c) Weekly 5-cm irrigation starting 55 days after planting (155 treatment). Shoot growth. NI treatment, compared to I treatment, reduced crop height 6.5% leaf area 11% although leaf y (water potential) generally was only 2 bars lower at midday during vegetative growth. Diunally, leaf elongation rate (in both treatment) was unespectedly fastest in early afternoon when leaf y was near the daily minimum. Leaf (solute potential) changes lagged behind y so high occurred at near minimum y values, and daytime elongation rates (presumably when temperature was not limiting) correlated with - leaf changes were associated with those of oraganic solutes; soluble leaf carbohydrates changes accounted for 40% of fluctuations. Consistently lower leaf elongation rates in NI treatment could m-not be explained by differences alone, however. Root growth water absorption. Water uptake at various soil depth and times (...).

This book was released on 2013-12-11 with total page 299 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 was 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 19 (thesis year 1974) a total of 10,045 theses titles from 20 Canadian and 209 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 19 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.

Available in PDF, EPUB and Kindle. Book excerpt: The Ogallala Aquifer is a large underground water source located under the High Plains and is used as the primary irrigation source for producers in the region. Hyper-extraction of the Ogallala is causing a reduction in irrigation capacity for a large part of the region. Confined animal feeding operations in western Kansas rely upon irrigated crops, mainly corn [Zea mays (L.)] as a source of feed. Research has shown that forage sorghum [Sorghum bicolor (L.) Monech] could meet the demands of the confined animal feeding operations while using less water than corn. An experiment was designed to evaluate corn and forage sorghum in Western Kansas. The objective of this research was to evaluate the water use and growth characteristics of irrigated and dryland corn and forage sorghum. Field experiments were conducted at two locations (Tribune Experiment Station, Tribune and a cooperator's field near Hoxie, Sheridan County Kansas) in 2011-2013. The experimental design at Tribune was a randomized complete block with four replications. A traditional replicated design was not possible at Hoxie. Multiple subsamples per plot were obtained and data are reported as means with standard errors. Corn and forage sorghum were grown under both dryland and fully irrigated conditions at both locations. Neutron access tubes were installed to monitor soil water. Aboveground biomass, intercepted solar radiation and volumetric soil water content were recorded at 5 sampling dates each growing season. Water use was similar between irrigated corn and forage sorghum. There were differences in biomass from year to year between the irrigated crops. Dryland water use was similar between the two crops and also had differences in biomass from year to year. Yields were significantly lower than average for all crops in 2012 due to drought conditions. Solar radiation interception correlated with aboveground biomass measurements. Aboveground biomass from the forage sorghum and corn was ensiled both years and analyzed for nutrient composition. This research suggests that forage sorghum silage may be an acceptable replacement for corn silage in areas with reduced irrigation capacities.
