(Texas A&M University. Libraries, 1977)The objectives of this study were to a) describe the present herbaceous cover at the Biological Experiment Section (BES), b) study association of vegetation and soil, c) identify tentative range sites, and d) evaluate ...
-
(Texas A&M University. Libraries, 1977)A study was initiated in August 1975 to illuminate the dietary interrelationships among four kinds of small ruminants of the Edwards Plateau of Texas. Interrelationships were based on the botanical and nutritive composition ...
-
(Texas A&M University. Libraries, 1984)Landsat multispectral scanner digital data was evaluated for use in determining brush canopy densities. A Landsat digital data simulation model was utilized to determine vegetation index sensitivity to changes in brush ...
-
(Texas A&M University. Libraries, 1977)Three species of perennial range weeds, common goldenweed (Isocoma coronopifolia (Gray) Greene), Drummond's goldenweed (Isocoma Drummondii (T.&G.) Greene), and spiny aster (Aster spinosus Benth.) were studied relative to ...
-
(Texas A&M University. Libraries, )A general trend occurring in many Less Developed Countries (LDC's) is that food production is not keeping pace with food demand. Growth in food production is consistently falling farther behind population growth making ...
-
(Texas A&M University. Libraries, 1988)Research was conducted on the effects of rotational grazing (RG) compared to continuous grazing (OS) on the behavior of cattle grazing on rangelands. Different livestock densities in the RG treatments were created by varying ...
-
(Texas A&M University. Libraries, 1983)The first of two experiments was initiated in August 1975 to investigate methods to improve the management of goats on rangelands. Experiment I compared the botanical and nutritive composition of diets collected from ...
-
(Texas A&M University. Libraries, 1980)Of all the problems that confront agriculture perhaps the unpredictability of weather is the most difficult to quantify. Twenty years of climatalogical data were obtained for Beeville, Texas and cumulative frequency ...
-
(Texas A&M University. Libraries, 1980)A study was intiated in May 1977 to examine the interaction of brush management and season on herbaceous production and composition,, chemical and botanical composition of cattle diets, and performance of lightweight steers ...
-
(Texas A&M University. Libraries, 1985)A four-part study was conducted at the Texas Agricultural Experiment Station, 56 km southwest of Sonora, Texas on the Edwards Plateau. The objective of the study was to provide a greater understanding of the hydrologic ...
-
(Texas A&M University. Libraries, 1985)The effects of grazing systems and climate on rangeland hydrology, soil and vegetation were assessed over a six year period at the Texas Agricultural Research Station, located 56 km southwest of Sonora on the Edwards ...
-
(Texas A&M University. Libraries, 1980)This study was conducted on the Sonora Agricultural Research Station, located on the Edwards Plateau. Study objectives were to: (1) determine the hydrologic response of a range site under very heavy continuous (EXT), high ...
-
(Texas A&M University. Libraries, 1987)Mechanisms of vegetation dynamics on a shortgrass (Hilaria belangeri) dominated semiarid Texas grassland were investigated. Study sites, which potentially support midgrass communities, were relatively homogeneous, open ...
-
(Texas A&M University. Libraries, 1983)Nitrogen is the nutrient that most frequently limits growth of grasses in rangelands. Symbiotic nitrogen fixation through establishment of legume-grass mixtures is a means of providing N inputs to rangeland systems. Siratro ...
-
(Texas A&M University. Libraries, 1976)Free ranging nilgai on the Norias Division of King Ranch, Inc., were studied during the period of 1971-1974 to derive information about the dynamics of population processes and their interaction with behavior and range ...
-
(Texas A&M University. Libraries, 1987)Uncertain forage production created by variation in climatic conditions and encroachment of undesirable brush species provide much of the business risk facing range livestock producers. This study focused on the evaluation ...
-
(Texas A&M University. Libraries, 1979)This study was conducted on the George Brockman Ranch, located near Sonora, Texas. The study area consisted of four 40 ha paddocks, two of which were burned with a headfire on March 1, 1977, and two paddocks which served ...
-
(Texas A&M University. Libraries, 1978)The purpose of this study was to determine the relative influence exerted by different sources of information on the adoption of deferred grazing systems by selected Texas ranchers. To achieve the purpose of this study the ...
-
(Texas A&M University. Libraries, 1987)Forage availability and diet selection by Spanish goats were monitored seasonally from summer 1983 to spring 1984 to determine the influence of selected brush management treatments and range site on botanical composition ...
