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 ...

[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 REQUEST OF AUTHOR.] Soybean cyst nematode (SCN) Heterodera glycines Ichinohe is the most serious pest of soybean [Glycine max (L.) Merr.] in the world. The effectiveness ...

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 ...

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 ...

Cut-leaved teasel is a biennial invasive weed that grows along roadsides and low disturbed areas. This research was to determine growth characteristics, herbicide efficacy, and seed production of teasel. Growth characteristics ...

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. ...

Two experiments are described, in which fall-calving cow-calf pairs grazed stockpiled tall fescue at three different endophyte infection levels (20, 51, and 89%) and four forage allowances (2.25, 3.00, 3.75, and 4.50% of ...

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 ...

Nitrogen (N) fertilizer unused by the crop is left to the fate of the processes of the N cycle, and can eventually lead to nitrate contamination of surface and ground waters. In order to address this problem, various methods ...

Traditionally, urea has been incorporated to avoid losses of N by ammonia volatilization. However, this option is not available when topdressing wheat. The objective of this project is to evaluate several strategies designed ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Drought is the major abiotic factor limiting soybean yield in the US. Under water deficit conditions, root systems may exhibit developmental plasticity resulting in morphological changes that extend the water-absorbing ...

Animals grazing tall fescue grass (Lolium arundinaceum) infected with Neotyphodium coenophialum consume the toxins ergovaline and other ergot alkaloids. This research included a series of experiments with two overall ...
