Effects of bisphenol A on growth and nitrogen nutrition of roots of soybean seedlings
Bisphenol A (BPA) is an environmental endocrine disruptor that seriously threatens ecological systems. Plants are the primary producers in ecological systems, but little information is available concerning the toxic effect of BPA on plants. In the present study, the effects of BPA on the growth and nitrogen nutrition of roots of soybean seedlings were investigated by using a root automatic scan ...

Inheritance and genetic mapping of resistance to Pythium damping-off caused by Pythium Aphanidermatum in ‘Archer’ soybean
Pythium damping-off and root rot of soybean [Glycine max (L.) Merr.] causes poor stands and consequently reduces yields. Resistance to seedling diseases caused by Pythium spp. was reported in the soybean cultivar Archer and was described to be associated with the Rps1k gene for resistance to Phytophthora sojae. To characterize the inheritance of Pythium damping-off resistance in Archer and to ...

Combined effects of bisphenol A and cadmium on growth and nitrate assimilation of soybean seedling roots
Bisphenol A (BPA) and cadmium (Cd) pollution exist simultaneously in many regions. However, little information is available regarding the combined effects of BPA and Cd pollution on plants. Plant roots are in direct contact with the soil, which is an important compartment of BPA and Cd. Here, the effects of combined BPA and Cd pollution on soybean seedling roots were evaluated in pot ...

Effects of bisphenol a on mineral nutrition in soybean seedling roots
Bisphenol A (BPA) is a ubiquitous chemical in the environment and is potentially harmful to plants. However, relevant studies on the effects of BPA on plants are relatively scarce. In the present work, the effects of BPA on the biomass (fresh and dry weight), absorptive function (activity and absorptive area), and mineral element levels in soybean (Glycine max L.) seedling roots treated with ...

Genetic improvement of seedling emergence of low-phytate soybean lines
Reduced seedling emergence of low-phytate (LP) soybean [Glycine max (L.) Merr.] lines with the pha1 and pha2 alleles has been a limiting factor in the development of LP cultivars. Crosses between normal-phytate (NP) and LP soybean lines have produced progeny with improved emergence. The objective of this study was to determine if LP lines with improved emergence are capable of producing progeny ...

Emergence of polymer-coated corn and soybean influenced by tillage and sowing date
No tillage often delays soil warming and drying, thus sowing too early in the spring may compromise seed viability due to prolonged exposure to cold and wet soil in the northern Corn Belt. Coating seed with a temperature-activated polymer may circumvent the adverse effects of exposing seeds to cold and wet soil. Germination and emergence of noncoated and polymer-coated corn (Zea mays L.) and ...

Scouting for pest in Iowa cover crops
Landscape diversification, including the use of cover crops, can provide habitat and forage for beneficial insects. This is especially true in the spring when there is a lack of food. Alternatively, cover crops can also support field crop pests, including moths, beetles, flies and slugs. The early spring vegetation, sometimes called a “green bridge,” provides resources until the row ...

Effects of Bisphenol A on antioxidant system in soybean seedling roots
Bisphenol A (BPA), an emerging pollutant in the environment, with potential toxic effects on plants; however, the toxicity mechanism remains largely unknown. The antioxidant system plays an important role in protecting plants against the damage of stress. Here, the effects of BPA on the antioxidant system [superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), ascorbic acid (AsA), ...

Conservation: It’s the right thing to do
A fable of six blind men and an elephant originated centuries ago somewhere on the Indian continent. In it the blind men try to identify an elephant by touching only one part. According to the fable each man came to a different conclusion as to what the elephant was. The parable illustrates that though opinions may vary, there’s some truth to be found in all of them. That’s the way ...

Photosynthesis, chlorophyll fluorescence characteristics and chlorophyll content of soybean seedlings under combined stress of bisphenol A and cadmium
Bisphenol A (BPA) is ubiquitous in the environment due to its continual application in plastics and epoxy resin industry. Cadmium (Cd) is a highly toxic heavy metal element mainly used in smelting, electroplating and plastic/dye manufacturing. BPA and Cd pollution exist simultaneously in many agricultural regions. However, little information is available regarding the combined effects of BPA ...

Effects of bisphenol a on key enzymes in cellular respiration of soybean seedling roots
Environmental endocrine disrupter–bisphenol A (BPA) is ubiquitous in the environment, with potential toxic effects on plants. Previous studies found a significant effect of BPA on levels of mineral nutrients in plant roots, but the underlying mechanism remains unknown. To determine how BPA influences root mineral nutrients, the effects of BPA (1.5, 3.0, 6.0, 12.0, 24.0, 48.0 and 96.0 mg L−1) ...

Recovery of Terrestrial Plants in Vegetative Vigor and Seedling Emergence Tests from Exposure to Atrazine
Ten species of terrestrial plants, including six dicotyledonous and four monocotyledonous species, were exposed to a direct overspray of atrazine according to U.S. EPA seedling emergence and vegetative vigor study guidelines and subsequently evaluated for potential recovery. For each species, NOER, ER10, ER25, and ER50 values were calculated (where possible) for a variety of guideline required ...

What raw materials can be used to produce organic fertilizer
Organic fertilizer is a kind of organic material fermented by microorganisms, such as plant residues, animal manure, organic by-products of processing industry, which can be applied to the soil to provide plant nutrition. Organic fertilizer can provide comprehensive, stable and long-term nutrient elements for plant growth, improve soil structure, improve soil buffering performance, water and ...

From Tobacco to Hemp: A 21st-Century Farmer’s Story
In February, Arable sat down with seventh-generation North Carolina farmer Charles Dietzel to discuss the newest incarnation of his legacy farm, Carolina Heritage Farms. We talked about his family’s transition from tobacco to agroforestry to now growing industrial hemp, and the role agtech has played in their decision to make the switch. With all the possibilities that come along with ...
