Mechanisms involved in mineral stress tolerance of cool‐season grasses infected by Neotyphodium spp. endophytes are not known. In a controlled‐environment experiment, two genotypes (DN2 and DN4) tall fescue ( Festuca arundinacea Schreb.) (E+) with their naturally occurring strains N. coenophialum (Morgan‐Jones Gams) Glenn, Bacon Hanlin, non‐infected (E−) isolines were cultivated nutrient solution at phosphorus (P) levels 31 mg P dm −3 (P+) 0.31 (P−) for 3 weeks. Diameters lateral roots, root...
<abstract> In 1987-1989, the first irrigated crops were grown on four large, precision weighing lysimeters at USDA-ARS Conservation and Production Research Laboratory Bushland, Texas, Southern High Plains (SHP). Thus began >25-years of full- deficit-irrigated crop growth, energy water balance, evapotranspiration (ET), yield, use efficiency (WUE) studies major SHP crops, including alfalfa, corn sorghum for both grain forage, cotton, soybean, sunflower, winter wheat. Alfalfa supported...
High grazing pressure can lead to soil erosion in pastures, causing increased sediment delivery waterways. The objectives of this research were evaluate the impact management and buffer strips on by assessing physical properties, hydrology, loads from pastures fertilized with broiler litter. Field studies conducted for 12 yr 15 small watersheds. Five strategies evaluated: hayed (H), continuously grazed (CG), rotationally (R), a strip (RB), fenced riparian (RBR). Broiler litter was applied...
<abstract> <b><sc>Abstract.</sc></b> The Soil Water Assessment Tool (SWAT) is a widely used watershed model for simulating stream flow, overland and sediment, pesticide, bacterial loading in response to management practices. All SWAT processes are directly dependent on accurate representation of hydrology. Evapotranspiration (ET) commonly the most significant portion hydrologic cycle, especially irrigated lands semiarid environments when ET demands met or exceeded. However, no studies using...
Irrigated agriculture in the Texas High Plains (THP) region faces severe challenges due to rapidly declining groundwater levels underlying Ogallala Aquifer, recurring droughts, and projected warmer drier future climatic conditions. Scheduling irrigation with appropriate deficits different crop growth stages could improve water use efficiency (IWUE), thereby enable additional savings valuable without severely compromising yield. Our objective was identify efficient growth-stage-based variable...
Abstract The Soil and Water Assessment Tool ( SWAT ) is one of the most widely used watershed models for simulating hydrology in response to agricultural management practices. However, limited studies have been performed evaluate model's ability estimate daily monthly evapotranspiration ET semiarid regions. values were simulated using Arc 2012 a lysimeter field managed under dryland conditions at USDA ‐ ARS Conservation Production Research Laboratory Bushland, Texas, compared with measured...
Abstract Surface energy imbalance problems have been underexplored especially under advective environments. Here, we present a novel analysis of surface fluxes from three distinct approaches—weighing lysimeter, eddy covariance (EC), and balance modeling for the 2014 sorghum 2016 corn crop seasons in Bushland, Texas. Our results suggest that EC system were evidently associated with two opposite evapotranspiration (ET) hysteresis patterns respect to net radiation water vapor pressure deficit...
This study aimed to investigate the differences in shoot and root traits, water use efficiency (WUE) drought tolerant (DT) maize (Zea mays L.) hybrids under full deficit irrigated conditions. A two-year greenhouse was conducted with four (one conventional hybrid, 33D53AM, two commercial DT hybrids, P1151AM, N75H, an experimental ExpHB) grown regimes (I100 I50, referring 100 50% of evapotranspiration requirements). Under stress, hybids N75, ExpHB showed more tolerance had either greater dry...
Abstract. Greater than 80% of the irrigated area in Southern High Plains is served by center-pivot irrigation, but subsurface drip irrigation (SDI) increasing due to several factors including declining well yields and improved crop water productivity (CWP), particularly for cotton. Not as established degree which reduced soil evaporation (E) SDI systems affects balance, available crop, overall savings. Grain corn ( L.) sorghum L. Moench) were grown on four large weighing lysimeters at...
