Abstract Several studies have demonstrated the water conservation potential of soil moisture sensor‐based irrigation scheduling on turfgrass areas; however, research is lacking accuracy satellite‐based measurements. A field study was conducted in 2023 to investigate values based electromagnetic pulses emitted from synthetic aperture radar mounted Sentinel‐1A. The estimates satellite remote sensing were compared measurements collected fairways 2 and 7 Sunset Golf Course (Las Campanas, NM) by...

Abstract Historically high cattle stocking rates and extreme drought contribute to the degradation of rangelands in southwestern United States. To mitigate erosion provide forage for this region, land managers seeded Eragrostis lehmanniana Nees (Lehmann lovegrass), a warm‐season perennial grass from South Africa 1930s. Although valuable forage, E. is strong competitor, responds well ecological disturbance, has become invasive. The purpose study was quantify plant–soil feedbacks (PSF) on...

Curtovirus spp., a group of widely distributed geminiviruses, are among the most significant plant pathogens in United States. Beet curly top virus (BCTV), vectored by beet leafhopper [ Circulifer ( Neoaliturus ) tenellus Baker], causes severe economic losses crops such as tomatoes, peppers, dry beans, sugar beets, melons, and leafy greens, particularly western In New Mexico, chile Capsicum annuum is vulnerable, with infected plants exhibiting symptoms stunting, chlorotic curled leaves,...

Genomic selection (GS) is a technology used for genetic improvement, and it has many advantages over phenotype-based selection. There are several statistical models that adequately approach the challenges in GS, such as linear mixed (LMMs). An active area of research development software fitting LMMs mainly to make genome-based predictions. The lme4 standard package generalized R-package, but its use analysis limited because does not allow correlation between individuals or groups be...

Vineyard applications of foliar nitrogen (N) and sulfur were evaluated in the Yadkin Valley North Carolina 2011 2012 as a means to modify grape composition Vitis vinifera cv. petit manseng. Four treatments applied each year randomized complete block design with six replicates vines each: untreated control, soil N at 30 kg/ha, 15 kg/ha plus 5 kg/ha. Fruit ammonia yeast assimilable (YAN) concentrations increased foliar-treated both seasons compared control vines. Total glycosides (TGGs) ∼80%...

Carya&amp;nbsp;illinoinensis (Wangenh.) K.Koch production has expanded beyond the native distribution as genetic diversity of species, in part, allowed trees to grow under broad geographic and climatic ranges. Research other plant species demonstrated that phytobiome enhances their ability survive thrive specific environments and, conversely, is influenced by prevailing environment genetics, among factors. We sought analyze microbiota pecan seedlings from controlled cross 'Lakota' × 'Oaxaca'...

As a result of the technological progress, use sensors for crop survey has substantially increased, generating valuable information modelling agricultural data. Plant spectroscopy jointly with statistical modeling can potentially help to assess certain chemical components interest present in plants, which may be laborious and expensive obtain by direct measurements. In this research, phosphorus content wheat grain is modeled using reflectance measured hyperspectral sensor at different...

In perennial plants such as pecan, once reproductive maturity is attained, there are genetic switches that regulated and required for flower development year after year. Pecan trees heterodichogamous with both pistillate staminate flowers produced on the same tree. Therefore, defining genes exclusively responsible inflorescence (catkin) initiation challenging at best. To understand these their timing, this study analyzed catkin bloom gene expression of lateral buds collected from a...

A compost program was developed on-farm, utilizing tree trimming biomass from a commercial pecan farm comprised of 14-year-old improved cultivar Western Schley (Carya illinoinensis) stands. The direct soil application shredded (P) and dairy manure (M) served as standard on-farm practice. Three composts were produced using P M with varying levels other inputs processing. PM contained only its production included weekly turning watering. two P, M, unfinished compost, clay inputs, either...

The objective study was describe relationship between fruit width, length, pericarp thickness, along with genetic potential for combining easy‐destemming attribute preferred morphology New Mexico (NM) pod‐type green chile. This investigation will define optimal selection criteria reducing force, while preserving distinctive NM We...

Abstract The desert Southwest is the oldest area of continuous crop production in continental USA. Tepary beans ( Phaseolus acutifolius A. Gray) were a part ancient, irrigated cropping systems, but they nearly lost during twentieth century. They are now subject heightened research and breeding activity. We wished to ascertain field performance varieties improved by selection within region with those selected outside region. In one study, evaluated two locations across seasons, another, at...

Abstract The southwestern United States–northern Mexico Borderland Region (SW) is an arid to semi‐arid region characterized by high temperatures, drought, and frequently saline soil conditions. Nonetheless, maize ( Zea mays ) has been cultivated in the for several millennia recently increasingly contributed a growing dairy industry. Water resources are declining, or brackish irrigation water increasing problem SW. Irrigation that highly can cause buildup of salts soil. Adapted SW germplasm...

Root biomass, root intercepts, and length density of SO4 rootstock grafted to Cabernet Sauvignon exposed under-trellis cover cropping (CC) with or without pruning (RP NRP, respectively) were evaluated over three years. The CC treatments included tall fescue (<i>Festuca arundinacea</i> Shreb.) varieties KY-31, RP, Elite II an 0.9 m wide, herbicide strip KY-31 inter-rows, RP. Around 70% grapevine biomass was observed at ≤60 cm soil depth, regardless treatment year. fescue/NRP vines had the...

Synthetic‐auxin herbicides are often used to control woody plants and aid in grassland restoration. Seed‐based restoration is common alongside herbicide applications there may be unintended effects of these on dryland at the seed seedling stages. Additionally, abiotic conditions time application influence herbicide–soil–plant interactions. We conducted a greenhouse study examine shrub‐control mix its interaction with soil type post‐herbicide water pulse desert plant seeds seedlings. In this...

Although treated effluent is being increasingly used to irrigate mature turfgrass, information on its use establish grass limited. Greenhouse experiments were conducted in 2015 and 2017 examine establishment nitrate leaching from three warm-season grasses: buffalograss [Buchloe dactyloides (Natt.) Eng.] 'SWI 2000', inland saltgrass [Distichlis spicata (L.) Greene], bermudagrass [Cynodon dactylon Pers.] 'Princess77'. All grasses grown with tailored (tertiary 15 mg L-1 of NO3 -N) water....

Abstract The germination of bermudagrass [ Cynodon dactylon (L.)
