Ethiopian mustard (Brassica carinata) is an ancient crop with remarkable stress resilience and a desirable seed fatty acid profile for biofuel uses. Brassica carinata one of six species that share three major genomes from diploid (AA, BB, CC) spontaneously hybridized in pairwise manner to form allotetraploid (AABB, AACC, BBCC). Of the these species, B. least understood. Here, we report chromosome scale 1.31-Gbp genome assembly 156.9-fold sequencing coverage carinata, completing reference...
Dwindling supplies of fossil fuels and their deleterious impacts on human health the global environment have intensified search for substitute energy sources. Biodiesel has been identified as a promising renewable diesel fuel due to several comparable sustainable properties. However, approximately 95% biodiesel is derived from edible oil crops, threatening current food supplies. Therefore, production potential inexpensive, non-edible, non-conventional bioenergy such Jatropha (Jatropha curcas...
Teff is the only cultivated cereal crop from genus Eragrostis and it major staple food of Ethiopians. In Ethiopia, quality teff its market price are primarily determined by grain color. The objective this study was to evaluate effects soil physicochemical characteristics across multiple locations in two main growing regions Amhara Oromia states Ethiopia on color nutritional a single variety. Grain samples were collected 24 field sites with popular variety ‘Quncho’ (DZ-Cr-387/RIL-355)....
Tef or Teff [Eragrostis tef (Zucc.) Trotter)] is a C4 photosynthesis tropical grass species within the Poaceae valued for its high-quality forage, fodder, and highly nutritious, gluten-free grain while showing great potential as bioenergy crop due to high biomass productivity climate resilience. Here, we document extensive phenotypic diversity of 368 E. accessions United States Department Agriculture (USDA)-Agricultural Research Service (ARS) national germplasm collection. Two morphological...
While most studies on floral hemp ( Cannabis sativa L.) concur that additions of nitrogen (N) increase plant growth, the performance is heavily influenced by environmental conditions, management and cultivar selection. In regions with a short growing season, availability soil N may determine developmental rates, final inflorescence biomass cannabinoid concentrations, but no have addressed this for field-grown under high-desert conditions. This field study evaluated effect supplemental...
Abstract Sowing date and sowing method can have a profound influence on the productivity of alternative crops like camelina in semiarid agroecosystems. The objective this study was to determine effects date, method, cultivar morphology, phenology, grain yield, oil concentration, oil, biodiesel production camelina. A 2‐year carried out at University Nevada, Reno Main Station Field Laboratory, during spring early summer 2016 2017. Treatments were two dates ( SD ) 18 March (early 17 April (late...
Camelina sativa is a promising oilseed crop used for dietary oil and as biofuel feedstock. C. highly adaptable, cool season that can be grown on marginal lands with minimal inputs, making it potentially suitable growth in Northern Nevada other cooler drier semi-arid regions of North America. A five-year (2011 to 2015) field trial was conducted evaluate the seed yield, content, biodiesel production potential eight cultivars Nevada. Columbia, Cheyenne, Calena, Blaine Creek were ranked top four...
ABSTRACT Spatially separated monoculture grasses and legumes within the same paddock (SS) may help alleviate constraints to widespread adoption of in pastures. A grazing study conducted during winter–spring seasons 2008 (steers, initial body weight [BW] = 236 ± 24 kg) 2009 (heifers, BW 245 40 at Raymond, MS, evaluated four forage systems (FS) two stocking rates (SR; 3 or 6 animals ha −1 ). Using ‘Marshall’ annual ryegrass ( Lolium multiflorum Lam.) ‘Durana’ white clover Trifolium repens L.),...
Abstract The objective of this two‐year study (2016–2017 spring) carried out at the University Nevada, Reno Main Station Field Laboratory, Reno, NV, was to evaluate effects nitrogen source, rate, and camelina cultivar on grain yield potential biodiesel production irrigated with reclaimed water. Treatments were two sources urea fertilizer [conventional (CU) polymer‐coated (PCU)], four N rates (0, 40, 80, 120 kg ha –1 ), cultivars (“Blaine Creek” “Pronghorn”) arranged in a 4 × 2 factorial...
ABSTRACT Determination of animal preference in the early stages evaluation process new forages may provide insights into potential performance as well plant responses to grazing. A 2‐yr study was conducted at Raymond, MS, determine grazing cattle between tetraploid and diploid annual ryegrass ( Lolium multiflorum Lam.) cultivars its relationship with morphological chemical characteristics. Treatments were two cultivars, Maximus Nelson, Marshall Gulf, arranged a 4 × Latin square design...
Abstract Leaf stage‐dependent defoliation is linked to the plant's physiological status and may be a more suitable criterion than time‐based intervals for harvesting forage grasses, but no reports of research with annual ryegrass ( Lolium multiflorum Lam. var. westerwoldicum ) were found. To address this, 2‐year field study was carried out at Raymond, MS , on Loring silt loam soil (fine‐silty, mixed, thermic Typic Fragiudalfs). Forage production, morphological characteristics nutritive value...
Cover cropping is a soil restorative strategy that can save degraded soils and offer additional benefits relative to the traditional fallow-based practice in semi-arid systems. This study aimed (i) quantify above (shoot)- belowground (root) biomass production, nutritive value, tissue carbon nitrogen concentrations from different annual cool-season cover crop systems, (ii) determine their effects on organic carbon, total nitrogen, respiration, microbial population environment. Treatments used...
Abstract There have been no systematic experiments conducted in Nevada's water-limited environment that examined the simultaneous benefits of soil health and feed value derived from cool-season cover cropping systems. The objective this study was to determine influence different annual crop systems on above belowground biomass production, plant tissue carbon nitrogen, forage nutritive (crude protein, acid, neutral detergent fiber), relative (RFV), short-term indicators under irrigation a...
The utilization of reclaimed wastewater is a suitable and sustainable approach to agriculture production in water-scarce regions. However, even though the treated reduce nutrient concentration such as phosphorus, 10,600 14,006 m3 water applied ha−1 year−1 on grass alfalfa hay crops Nevada can lead soil phosphorus buildup over an extended period. This study evaluated effectiveness forage systems (FS) monoculture grass, legume, their mixtures herbage accumulation, tissue concentration,...
Increasing pressure over water resources in the western U.S. is currently forcing alfalfa (Medicago sativa L.) producers to adopt water-saving irrigation techniques. Crop yield forecasting tools can be used develop smart scheduling methods that estimate future effects of a given amount applied during current event on yield. In this work, linear model and random forest were irrigated crops northern Nevada. It was found (rain + irrigation), occurrence extreme temperatures, wind have greater...
ABSTRACT Studying grazing behavior of ruminants may help increase the understanding use forage systems varying types and composition. This study was conducted during 2008 at Raymond, MS, to evaluate time by on various examine any relationship with pasture composition stocking rate (SR). Annual ryegrass ( Lolium multiflorum Lam. ‘Marshall’) white clover Trifolium repens L. ‘Durana’) were used create system treatments either monoculture grass (MG) or legume (ML), a binary mixture (MIX),...

In arid and semiarid regions, crop production has high irrigation water demands due to low precipitation. Efficient management strategies can be developed using growth models assess the effect of different practices on productivity. The leaf area index (LAI) is an important parameter used in modeling. Measuring LAI requires specialized expensive equipment not readily available for producers. Canopy cover (CC) canopy height (CH) measurements, other hand, obtained with little effort mobile...
