Abstract:
... Excessive inputs of phosphorus (P) and nitrogen (N) trigger eutrophication of the water bodies, which promotes the undesirable growth of algal bloom and deterioration of the water quality, and aquatic biodiversity. Macrophytes provide an environmentally benign and economically viable paradigm for the ecological restoration of eutrophic aquatic ecosystems. Water lily (Nymphaea) is largely used as o ...
... Hydroponics has become a popular production technology for leafy greens in greenhouses. However, year-round production of cool-season leafy greens remains challenging due to costly heating and cooling during winter and summer seasons, depending on location. Therefore, the objective of this study is to investigate the effect of nutrient solution cooling and heating in deep-water hydroponic systems ...
... Crapemyrtle bark scale [CMBS (Acanthococcus lagerstroemiae)], a newly emerged pest in the United States, has spread to 16 U.S. states and unexpectedly spread on a native species american beautyberry (Callicarpa americana) in Texas and Louisiana in 2016 since it was initially reported on crapemyrtles (Lagerstroemia sp.) in Texas in 2004. The infestation of CMBS negatively impacted the flowering of ...
... The genus Chionanthus, known as fringetrees, is a member of the olive family (Oleaceae). Chionanthus virginicus is an understory tree or shrub with a wide range in forests of the eastern United States and is used as an ornamental tree that is known to be free of insects and disease in the wild. The species is tolerant of a wide range of environmental conditions, and there is interest in developing ...
... Over 95% of U.S. cotton post-harvest processing is done using saw gins. Gin saws have long been supplied in three thicknesses. We quantified the effect of saw thickness on lint turnout, lint value, and seed damage, variables that determine producer returns. Saw cylinders stacked with 0.9144 and 1.143 mm (0.036 and 0.045 in.) thick saws, the thinnest and thickest available, were operated in laborat ...
... Enhancing genetic diversity to breed cotton (Gossypium hirsutum L.) for water‐limited production in the Texas High Plains is one objective of the Texas A&M AgriLife Research breeding program in Lubbock. CA 4008 (Reg. no. GP‐1099, PI 698821) was derived from TX 307 (PI 165390) and 07‐A‐05, an unreleased breeding line. TX 307, wild material of species Gossypium hirsutum, was used as a parent based o ...
... Organic cotton (Gossypium hirsutum L.) production in the United States is steadily growing because of increased consumer demand, market premium prices, and regulatory shifts. As organic production expands in the United States, adventitious presence of genetically engineered (GE) traits caused by either pollen‐ or seed‐mediated gene flow from nonorganically grown sources of cotton raises concerns a ...
... Sustaining irrigated corn (Zea mays L.) production under changing climate and reduced irrigation water availability presents a key challenge for producers in the Northern High Plains (NHP) of Texas. We assessed climate change impacts on corn production at Bushland in the NHP region using the CERES-Maize model under 36 future climate scenarios. These scenarios included nine global climate models (G ...

Abstract:
... Field evaluation of cotton for resistance to Fusarium oxysporum f. sp. vasinfectum Race 4 (FOV4) is important in breeding. In this study, an 8 × 8 Latin square design was arranged in two FOV4‐infested fields each with two trials to evaluate eight cotton (Gossypium hirstum) cultivars based on mortality rate (MR) and root vascular staining (RVS). For a comparison, two trials of the same design were ...
... Globalization and intensified volume of trade and transport around the world are accelerating the rate of biological invasions. It is therefore increasingly important to understand the processes through which invasive species colonize new habitats, often to the detriment of native flora. The initial steps of an invasion are particularly critical, as the introduced species relies on limited genetic ...

Abstract:
... ‘Pueblo’ is a new pecan (Carya illinoinensis) cultivar released and patented by the U.S. Department of Agriculture, Agricultural Research Service (USDA ARS). This cultivar is the first to be released with a compact tree size, great precocity, early nut maturation, high yield potential, and scab resistance. ‘Pueblo’ should perform well in the West, central Texas, and as far north as southeastern Ka ...

Abstract:
... In August 2020, a New York (NY) State vegetable grower sought assistance to identify a malady of tomato (Solanum lycopersicum). The plants were grown from saved seed that had been planted annually in NY and/or Florida for over 15 years without significant disease problems, but the identity of the cultivar was not known. Submitted photos showed severely stunted plants with distorted leaves (crinkli ...
... ContextInvestigating agronomic responses of dryland maize (Zea mays L.) systems under global change could provide important insights in designing climate-resilient cropping systems.Aims and methodsIn this study, we integrated Agricultural Production Systems sIMulator (APSIM) with Representative Concentration Pathways 8.5 and 20 Global Climate Models to systematically: (1) calibrate and validate AP ...
... Vaccinium stamineum (deerberry) is a highly variable diploid species in section Polycodium. Deerberry is native on excessively drained sandy soils from southeastern Ontario, south through the Florida peninsula to Lake Okeechobee, west to eastern Texas and southeastern Kansas. The V. stamineum used in this study were tall plants (2–4 m) native in north Florida, with a plant architecture similar to ...
... Fusarium oxysporum f. sp. vasinfectum race 4 is a causal agent of Fusarium wilt of cotton (Gossypium spp.). This study aimed to characterize the existing distribution and frequency of current field populations of F. oxysporum f. sp. vasinfectum race 4 genotypes in the San Joaquin Valley (SJV) of California and Lower Valley El Paso, TX and examine representative isolates for aggressiveness during d ...
... To accurately estimate forage yield of experimental lines and cultivars without the time and expense of harvesting with and maintaining a plot harvester would aid cool‐season forage grass researchers and breeders in cultivarselection and advancement. A cool‐season annual grass forage trial was conducted at the Texas A&M Research Farm during the 2015–2016 and 2016–2017 growing seasons. The trial in ...
... Pecan is one of the top five most widely consumed tree nuts, and pecan nut quality is a major factor for consideration in breeding better pecan cultivars for use by producers. However, the pecan industry faces a hurdle to evaluate its nutmeat taste, and there has so far been limited evaluation of consumer attitudes toward pecan nutmeat. This study aimed to investigate the consumer (n = 198) hedoni ...
... Cotton (Gossypium hirsutum L.) and potassium (K) dynamics are not well understood particularly in soils with high K levels. Potassium is important for cotton reproductive development as it influences the number, size, and weight of bolls and can improve fiber quality by mitigating moisture stress. In the case that soil cannot replenish solution K from exchangeable reserves to meet the plant demand ...
... Fusarium wilt of cotton, caused by the soilborne fungal pathogen Fusarium oxysporum f. sp. vasinfectum (FOV), occurs in regions of the United States where cotton (Gossypium spp.) is grown. Race 4 of this pathogen (FOV4) is especially aggressive, and does not require the co-occurrence of the root knot nematode (Meloidogyne incognita) to infect cotton. Its sudden appearance in far-west Texas in 2016 ...
... The bioactive properties of the almond kernel cultivars were determined in the 10 min sonication period with the highest values being observed in the “Ferraduel” almond cultivar. While total phenolic contents of almond kernel extracts obtained by extraction for 10 min change between 10.97 mg GAE/100 g (Texas) and 106.25 mg GAE/100 g (Ferraduel), total phenolic contents of almond kernels extracted ...
