(Texas A&M University. Libraries, 1985)A model was developed to simulate the growth of individual wheat plants within a field community. Based on hourly observations of irradiance and temperature, one portion of the model (PHOTO) computes the daily photosynthesis, ...
-
(Texas A&M University. Libraries, 1994)Eleven Pennisetum orientale L. C. Rich. accessions from different geographical regions were studied at College Station, Texas for chromosome number, morphology, method of reproduction, and fertility. Differences were ...
-
(Texas A&M University. Libraries, 1994)Ethylene production is reportedly influenced by plant nutrient status. A field and two growth chamber studies were conducted to determine N fertility effects on ethylene production throughout development of cotton (Gossypium ...
-
(Texas A&M University. Libraries, 1969)Blue panicgrass (Panicum antidotale Retz) plants were grown in a sand culture, subjected to contrasting forms of nitrogen fertilization applied at differing rates and harvested at varying intervals following fertilization. ...
-
(Texas A&M University. Libraries, 1987)Slow establishment of the genus Leucaena from seed has been attributed to low seedling vigor and late nodulation. Observation of early seedling growth indicated that partitioning of a large proportion of resources to the ...
-
(Texas A&M University, 1999)Legumes play important roles in tropical forests due to their contribution to N₂-fixation and nutrient cycling. Our objectives were to determine which soil properties, if any, affect the occurrence and distribution of tree ...
-
(Texas A&M University. Libraries, 1985)Two sorghum cultivars, ATx378 x RTx430 [(34), higher stem carbohydrates and slower rate of senescence] and ATx378 x RTx7000 [(37), lower stem carbohydrates and more rapid rate of senescence] were utilized in a study of ...
-
(Texas A&M University. Libraries, 1966)St. Augustinegrass, Stenotaphrum secundatum is a warm-season perennial species of the tribe Paniceae. The species is classified as a sod-forming grass and is characterized by its stoloniferous growth habit and absence of ...
-
(Texas A&M University. Libraries, 1980)Three warm-season grass species were grown to evaluate relationships between forage quality and environmental conditions. Two selections of kleingrass (Panicum coloratum L.), Kleingrass 75 and Kleingrass 75-25, green ...
-
(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 ...
-
(Texas A&M University. Libraries, 1985)There have been many investigations into the time interval when yield is most susceptible to stress. Knowledge of this interval is important to understanding yield potential, for modeling, irrigation scheduling, and the ...
-
(Texas A&M University. Libraries, 1987)Susceptible crop species may exhibit symptoms of iron (Fe)-deficiency chlorosis when grown on high pH, calcareous soils. A series of field and greenhouse experiments was conducted to determine whether differences exist ...
-
(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 ...
-
(Texas A&M University. Libraries, 1987)Research was conducted to formulate techniques for modeling phenological development of weed populations. Techniques which are currently used for modeling development rate of insect populations were reviewed and tested for ...
-
(Texas A&M University. Libraries, 1987)Effects of tillage and fertilizer placement and rate on sorghum (Sorghum bicolor L. Moench) yield and N accumulation in 1985 and 1986 were evaluated on a Weswood soil near College Station, Texas. Four N rates (0, 50, 100, ...
-
(Texas A&M University. Libraries, 1967)
-
(Texas A&M University. Libraries, 1988)Ridge-furrow tillage systems establish heat and moisture fluxes in two dimensions. However, no models had been developed previously which permitted quantitative investigations of temperature fluctuations, redistribution ...
-
(Texas A&M University. Libraries, 1994)This study focused on the development of a passive in situ sampling method for the detection and assessment of atmospheric contamination. Conifer needles were collected adjacent to a wood-preserving waste bioremediation ...
-
(Texas A&M University. Libraries, 1994)Landscape planting has been designed with minimal considerations given to the plant water requirements. Little research has been done to measure the water requirements by plants in urban areas. Field measurements and the ...
-
(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 ...
