The use of plastic biodegradable mulch (BDM) in many vegetable crops such as tomato ( Solanum lycopersicum L.), broccoli Brassica oleracea L. var. italica), and pepper Capsicum annuum L.) has been proven to be equal benefit polyethylene (PE) mulch. However, there are limited research findings on the performance BDM with a large fruited crop pumpkin Cucurbita pepo where fruit can rest directly for an extended period. To investigate whether heavy might cause degrade more quickly than expected,...
There is growing appreciation of arbuscular mycorrhizal effects on soil properties and their potential consequences plant behavior. We examined the possibility that may directly influence water relations. Using wild-type noncolonizing bean mutants planted into soils previously produced using or nonmycorrhizal sorghum plants, we partitioned stomatal conductance drought resistance root components, testing whether fungi occurred mostly via mycorrhization roots, soil, both. The mutation itself...
• Foliar dehydration tolerance of three mycorrhizal and nonmycorrhizal legumes is presented here. Leaf water potential, osmotic adjustment soil matric potential at the end a lethal drying episode were compared in soybean, cowpea bush bean colonized or uncolonized by Glomus intraradices. Lethal leaf similar among treatments except for which plants given low phosphorus fertilization had values 0.3–0.4 MPa lower than higher fertilization. Mycorrhizal symbiosis did not affect potential....
Plasticulture systems with polyethylene (PE) mulch and drip tape are common for production of peppers ( Capsicum annuum L.) in the United States because their soil warming, moisture conservation, other advantageous effects. However, disadvantages include disposal costs plastic pollution environment temperature stress warm climates black mulch. Use biodegradable mulches (BDMs) is becoming more common, as they provide same benefits PE without problems. In 2017 2018, we conducted experiments...
The brown marmorated stink bug ( Halyomorpha halys ) is a nonnative insect that damages vegetables and other crops in the United States. Because of current lack effective control options for organic growers to combat this pest, barrier screens with different mesh sizes were evaluated their ability exclude bug, provide entry beneficial species, produce high percentage marketable yield. Barrier 1/6-, 1/8-, 1/25-inch sizes, along unscreened controls, covered ‘Aristotle’ bell pepper Capsicum...
Salinity and dissolved selenium are known water-quality impairments in the lower Gunnison River watershed of western Colorado. is a concern because its adverse effects on agricultural land equipment, municipal industrial users. The Montrose Arroyo Montrose, Colorado, contains residential areas as well undeveloped has undergone substantial land-use change since early 1990s. Previous sampling efforts indicated salinity concentrations loads have remained constant began 1990s; however, recent...
Plastic mulch films contribute to improved crop yield and quality for vegetable small fruit cropping systems. Although the single-season agronomic performance of conventional polyethylene mulches soil-biodegradable (BDMs) are similar, over time BDMs can begin break down during storage subsequently not provide season-long soil coverage. In this study, changes in physicochemical properties were investigated 3 years indoor (2015–18) under ideal environmental conditions two laboratories. Mulches...
Biodegradable mulches (BDMs) provide a unique advantage to growers in that they can be tilled into the soil after use, eliminating disposal costs include time, labor, and equipment needs. Biodegradation of BDMs assessed by presence visible mulch fragments; although this is not direct measure biodegradation, it provides an initial estimation biodegradation. We carried out three field experiments develop protocol for quantifying BDM fragments incorporation mulch. Expt. 1 was done at Mount...
Starting in the 1990s, health care providers began prescribing opioids to patients as pain relievers, believing they were safe. However, many became addicted these pills. In 2017, US Department of Health and Human Services declared a public emergency fight opioid epidemic. This crisis was prevalent East Tennessee, where residents prescribed opioids.Librarians at an academic medical center library Tennessee analyzed information requests related pain, mental health, addiction over last fifteen...
Abstract Kousa dogwood (Cornus kousa Hans.) trees often develop unattractive leaf curling throughout canopies during hot and/or dry weather. Aesthetically superior were compared to control for their ability tolerate summer stress, in an established plantation 2000 and 2001. An index of curl revealed that showed less than controls June, July August Superior had higher stomatal conductance both groups years, with seasonal averages 16 40% trees. Leaf water status, characterized by osmotic...
