(Texas A&M University. Libraries, 1980)A study was conducted to evaluate the (1) effectiveness of and validity of conducting turfgrass shade adaptation research under saran shade cloth vs. post oak tree shade, (2) shade adaptation mechanisms of Kenwell tall ...
-
(Texas A&M University. Libraries, 1974)Six varieties, Sudax 11, X-1750 (sorghum x sudangrass), Trudan I (sudangrass x sudangrass), Greenleaf (sudangrass pollinator for both Sudax 11 and X-1750), Atlas B and 31-12 B (seed parents for Sudax 11 and X-1750, ...
-
(Texas A&M University. Libraries, 1986)Three crop moisture stress indices (CMSI1, CMSI2 and CMSI3) are proposed. In computing index 1 and 2, stress is assumed to occur when the actual to potential transpiration ratio (AT/PT) falls below a critical level, while ...
-
(Texas A&M University. Libraries, 1987)Comparative drought resistances of eleven major warm-season turfgrasses were evaluated in the field after withholding irrigation. The relative importance of the drought avoidance and tolerance mechanisms was also investigated. ...
-
(Texas A&M University. Libraries, 1995)Pesticide use in cotton may trigger plant responses ranging from yield enhancement to delayed maturity and yield reductions. Profenofos, an insecticide/miticide, can result in leaf reddening and necrotic spotting. However, ...
-
(Texas A&M University. Libraries, 1970)Parameters of yield, tiller number, leaf area, and crown weight were studied for a 20-week period on kleingrass (Panicum coloratum L.) which was varied as to the dates at which it was first cut and the frequency and height ...
-
(Texas A&M University. Libraries, 1980)Wheat (Triticum aestiuum L. em. Thell.) is used as both a grain and a forage crop throughout Texas. It is the general practice to graze wheat during the winter, remove the cattle in the spring and allow the wheat to produce ...
-
(Texas A&M University. Libraries, 1987)The effects of the grass-specific herbicide haloxyfop {2- [4- [[3-chloro-5-(trifluoromethyl)-2-pyridinyl]oxy]-phenoxy]propanoic acid} on the growth and ultrastructure of susceptible sorghum (Sorghum bicolor (L.) Moench.) ...
-
(Texas A&M University. Libraries, 1990)Effects of high temperature upon photosynthesis, respiration, and growth and yield of rice plants (Oryza sativa L.) were studied under controlled environments. Photosynthesis and respiration were determined by the CO2 ...
-
(Texas A&M University. Libraries, 1987)The chloroacetamide herbicides are effective in controlling many grassy weeds. The commonly used chloroacetamide herbicides are alachlor [2-chloro-N-(2,6-diethylphenyl)-N-(methoxymethyl)acetamide] and metolachlor ...
-
(Texas A&M University. Libraries, 1975)LANDSAT multispectral scanner data were selected to represent periods of adequate soil water, soil water deficit, and beginning of soil water recharged in Brazos County, Texas to evaluate LANDSAT multispectral scanner data ...
-
(Texas A&M University. Libraries, 1972)Sixty-six buffelgrass hybrids representing four crosses and sexual and apomictic methods of reproduction were evaluated for in vitro dry matter digestibility (IVDMD) and cell-uall digestibility (IV/CUD). Percent leaves and ...
-
(Texas A&M University. Libraries, 1990)Seed treatments using cyometrinil, oxabetrinil, and flurazole have effectively safened grain sorghum against chloroacetamide herbicides such as alachlor and metolachlor at rates of 2.24 or 3.36 kg/ha under field and ...
-
(Texas A&M University. Libraries, 1979)Turfs of bermudagrass (Cynodon dactylon (L.) Pers. cv. 'Tifgreen'), Kentucky bluegrass (Pao pratensis L. cv. 'Touchdown'), perennial ryegrass (Lolium perenne L. cv. 'Manhattan'), and four St. Augustinegrass (Stenotaphrum ...
-
(Texas A&M University. Libraries, 1985)A deterministic, compartmental growth model of greenhouse tomato plants, written in Pascal computer language, was developed based on a leaf assimilation model and a model of a theory that the photosynthesis rate is controlled ...
-
(Texas A&M University. Libraries, 1990)A technique was developed to expose corn seedlings to EPTC, a volatile herbicide, or CGA-136872, a non-volatile herbicide. This technique was used to document the cross tolerance of a CGA-136872-tolerant variety, Funk ...
-
(Texas A&M University. Libraries, 1994)Field and greenhouse experiments examined the interference of semi-dwarf, winter wheat (Triticum aestivum L.) by Italian ryegrass (Lolium multiflorum Lam.). Sharp declines compared to controls in leaf area and above ground ...
-
(Texas A&M University. Libraries, 1977)The distribution and metabolism of 14C-1- From a nursery of 200 grass introductions six accessions were chosen for evaluation of forage and seed yield and quality in response to management practices. Species represented ...
-
(Texas A&M University. Libraries, 1995)Iron-deficiency is a significant constraint to subclover

Methomyl-induced phytotoxicity in cotton (G̲o̲s̲s̲y̲p̲i̲u̲m̲ h̲i̲r̲s̲u̲t̲u̲m̲ L.) (Texas A&M University. Libraries, 1992)Understanding the causes of insecticide-induced stress to crop plants could help to increase yields. This study examined phytotoxicity of methomyl (S-methyl-N- [(methylcarbamoyl)oxy]-thioacetimidate) on cotton (Gossvpium ...
