[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Water deficit is responsible for significant losses in soybean (Glycine max (L.) Merrill) yield under dryland conditions. Under drought, increases in ...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Soybean cyst nematode (SCN) Heterodera glycines Ichinohe is the most serious pest of soybean [Glycine max (L.) Merr.] in the world. The effectiveness ...

Soybeans (Glycine max [L.] Merr.) are a good source of protein and oil. Despite being a very good source of protein, soybeans nutritional value is limited by low proportion of sulfur amino acids methionine and cysteine ...

A revolution in production agriculture has occurred over the past decade; the development and use of herbicide-resistant crops. Glyphosate is an effective, broad spectrum and offers flexible application timing with minimal ...

The possibility of in waterhemp has been of concern to Midwest corn and soybean producers due to a heavy dependence on glyphosate as a weed control tool and the increased incidence and problematic nature of waterhemp in ...

Accumulation of the potent carcinogen, aflatoxin, in maize poses a significant health risk to humans and animals. Most commercially grown maize lines are susceptible to infection by the fungus that synthesizes aflatoxin, ...

Silvopasture offers Midwest landowners the opportunity to plant trees in their pastures without significant loss of forage production. However, much of the pasture in the Midwest is dominated by tall fescue (Schedonorus ...

The planting of adequate soybean seeds does not always materialize into a satisfactory final plant stand. Many different environmental factors play an important part in the process of soybean germination and emergence. ...

Salinity drastically reduces crop yield by limiting water uptake and causing ion-specific stress. Soybean is sensitive to soil salinity. Previous studies, however, have shown that there is variability among soybean genotypes ...

Poison hemlock is a biennial, toxic and invasive weed that grows along roadsides, pastures and low-disturbed areas. Research was conducted to determine seed ecology, growth characteristics and response to herbicides. Seed ...

The development of Imidazolinone (IMI) Resistant (IR) rice now allows rice producers to selectively control red rice (Oryza sativa, O. rufipogon, and O.nivara), weedy relatives of commercial rice (O. sativa). Imazethapyr ...

Alley cropping is an agroforestry practice that utilizes the space between rows of trees to produce an alternate crop. Tall fescue demonstrates shade tolerance and may be well suited for the production of certified seed ...

Barley yellow dwarf virus is one of the most widespread viral diseases of wheat. Yield reductions up to 70% have resulted from barley yellow dwarf virus (BYDV) infection. Several aphid spp. transmit BYDV. In Missouri, the ...

Soybeans (Glycine max [L.] Merr.) are a major source of vegetable protein and edible oil. The nutritional quality of these seed components depends upon the relative abundance of specific proteins and fatty acids. Additionally, ...

Annual ryegrass (Lolium multiflorum Lam.) and cereal rye (Secale cereale L.) are two forages that fit well into mixed row crop/livestock operations as they can be used both as a cover crop and as a source of winter pasture. ...

Changing the content of the five major soy-oil fatty acids is important to enhance food, fuel and other applications of soybean oil. In addition to genetic effects, the growth environment can significantly affect oil ...

Fall herbicide applications have increased in popularity in recent years. Little is known of how fall herbicide applications impact soil conditions, insect populations, and winter and summer annual weed populations. Few ...

Soybean (Glycine max [L.] Merr) is considered an excellent protein source for both humans and livestock. Further improvement of quantity and quality of soybean protein is vital for maintaining the utility of this versatile ...

Composition of soybean seeds is important to manufacturers of tofu and natto food products. The effect of environment on seed composition of tofu and natto soybean cultivars was measured in Missouri in 2004 and 2005. The ...

Previous studies suggested that ABA accumulation is required to maintain maize primary root elongation under water deficit and that one of the functions of ABA is to restrict ethylene evolution. These studies were conducted ...
