Raab, Quinton Joe (Texas A&M University. Libraries, 1985)Inbred lines, F1 crosses and progeny from F2 populations were utilized to determine if the primary loci which control pericarp color (R, Y, B1, B2 and S) affected tannin presence and concentration differently when they ...
-
Perez, German Jose (Texas A&M University. Libraries, 1985)New elite inbred lines derived from crosses involving genetic material from the Sorghum Conversion Program were evaluated for combining ability and agronomic performance at four diverse locations across Texas. Entries were ...
-
Kebede, Yilm (Texas A&M University. Libraries, 1983)Performance tests, growth analysis, as well as evaluations of combining ability and heterosis were carried out during 1981 and 1982 seasons to determine morphological, physiological, genetic and adaptational differences ...

Howell, T. A.; McFarland, M. J.; Reddell, D. L.; Brown, K. W.; Newton, R. J.; Humphreys, K. B. (Texas Water Resources Institute, 1980-12)An adequate description of soil moisture movement is necessary for solution of agriculturally oriented problems such as irrigation, drainage and runoff control. Three approaches for determining the hydraulic properties of ...

Howell, T. A.; McFarland, M. J.; Reddell, D. L.; Brown, K. W.; Newton, R. J.; Rodriguez, P. B.; Van Bavel, C. H. M.; Reeder, E. L. (Texas Water Resources Institute, 1980-12)The scientific design and management of a modern irrigation system requires that the designer or manager have knowledge of site and plant criteria such as infiltration, drainage, soil fertility, plant water needs, and plant ...
-
Gay, Scott Lallier (Texas A&M University. Libraries, 1981)Over time, whole plant growth is nearly the balance between photosynthesis and respiration. This research consisted of devising and testing a model which predicts plant respiration rates from knowledge of the photosynthesis ...
-
Howell, T. A.; Brown, K. W.; Newton, R. J.; Redden, D. L.; McFarland, M. J. (Texas Water Resources Institute, 1981-03)High frequency irrigation implies the uniform, frequent application of water to crops. The fequency may range from several irrigations per week to daily irrigation to even several irrigations per day in greenhouse and ...
-
Chavarria Fernandez, Normando Aureliano (Texas A&M University. Libraries, 1985)Two crops of Fe efficient (RTx2536) and inefficient (BTx378) sorghum were grown in a greenhouse study both with and without added CaCO3 in sand which was crushed and separated by sedimentation techniques to obtain particle ...
-
Peterman, T. Kaye (1978)Acid invertase was isolated from Sorghum bicolor (L.) Moench. Activity was determined in a crude enzyme preparation by determining the increase in glucose and fructose and the decrease in sucrose. TMS derivatives of the ...
-
McKenzie, David Bruc (Texas A&M University. Libraries, 1984)Growth chamber studies were conducted to develop a visual test for differentiating sorghum cultivar Fe-efficiency in CaCO(,3) buffered nutrient culture. Nine sorghum cultivars were germinated in vermiculite and grown for ...
-
Adam, Adam Ibrahim (Texas A&M University. Libraries, 1982)The major soils comprising the Gezira scheme are Hosh, Suleimi and Laota. These soils are dark grayish brown to dark brown, calcareous clays with < 1% organic matter.<p> The mineralogical data show that the soils of the ...
-
Welker, Jeffrey Martin (Texas A&M University. Libraries, 1985)Nitrogen is consistently reported to be an essential element which limits plant growth in grazed ecosystems. Subsequently mechanisms facilitating efficiency of nitrogen allocation and utilization may be an essential component ...
-
Parkpian, Preed (Texas A&M University. Libraries, 1983)An Fe dust waste accumulates as a by-product from the steel industry and poses a disposal problem. Since the waste contains approximately 43% Fe, 5.4% Zn, and 1.9% Mn, it shows potential for recycling as a plant food. ...
-
Johns, Don (Texas A&M University. Libraries, 1980)A controlled environment study of evapotranspiration from St. Augustinegrass turf, Stenotaphrum secundatum (Walt.) Kuntze, showed that, under well-watered conditions, evapotranspiration was influenced to a greater extent ...
-
Howell, T. A.; McFarland, M. J.; Reddell, D. L.; Brown, K. W.; Newton, R. J.; Dahmen, P. (Texas Water Resources Institute, 1980-12)Past irrigation research on peanuts has shown that when the plant is exposed to soil moisture stress at different crop growth stages, different responses seem to exist between the Spanish and the Florunner peanut varieties. ...
-
Baker, John Morgan (Texas A&M University. Libraries, 1987)A growth chamber experiment was conducted to test the hypothesis that an unirrigated plant could survive if its root system overlapped with irrigated plants on either side. A box 1.8 m long, 0.2 m deep, and 0.24 m front ...
-
Morris, Dolen Ray (Texas A&M University. Libraries, 1985)Arrowleaf clover (Trifolium vesiculosum Savi) and ryegrass (Lolium multiflorum Lam.) are commonly grown together but the fertilizer N needs of these plants when grown in mixture are not well understood. Two greenhouse and ...
-
Munger, Philip Harrison (Texas A&M University. Libraries, 1986)Field and greenhouse research was conducted to evaluate the effects of interspecific competition on water relations, morphology, and yield of soybeans [Glycine max (L.) Merr. cv. Hutton] and velvetleaf (Abutilon theophrasti ...
