Controlling Chickweed And Henbit In Alfalfa, J. F. Freeman

Agronomy Notes

Chickweed and henbit weeds are bad in alfalfa this fall. DNBP (premerge or Sinox PE) sprayed on infested fields at rate of 1 to 3 qt in 20 to 40 gallons of water per acre may destroy the weeds without harm to the dormant alfalfa. Use the higher rate if chickweed is matted on the ground or if henbit is heavy in the stand. Spray only when the temperature is 55 to 60 degrees or warmer and fair weather is predicted for 12 hours after treatment. The 1-qt rate applied in early fall when chickweed is very small (not until …

Southeast South Dakota Experiment Farm Annual Progress Report, 1965, Agricultural Experiment Station

Agricultural Experiment Station and Research Farm Annual Reports

This fifth annual report of the research program at the Southeast South Dakota Experiment Farm is presented herewith. The report has special significance for those engaged in agriculture and the agriculturally related businesses in the nine county area of southeast South Dakota, but it will be useful to many outside the area. The results shown are not necessarily complete nor conclusive. Interpretations given are tentative because additional data resulting from continuation of these experiments may result in conclusions different from those based on any one year.

Controlling Annual Grasses In Spring Seeded Alfalfa With Eptc, J. F. Freeman

Agronomy Notes

Many Kentucky farmers plan to sow alfalfa in early spring on a prepared seed bed. A main objective is to avoid or reduce most of the damage of alfalfa weevil on the first-year crops . Eptam 6 E sprayed on the prepared seed bed at rate of 2 quarts in 10 to 20 gallons of water per acre and disked in 3-4 inches deep right behind the sprayer usually gives good control of annual grass weeds and some control of broadleaf weeds as well. A second disking, crosswise to the first, is needed for thorough mixing of the herbicide with …

Genetic Control Of The Metabolism Of O-Hydroxycinnamic Acid Precursors In Melilotus Alba, Francis A. Haskins, T. Kosuge

Department of Agronomy and Horticulture: Faculty Publications

In sweetclover (Melilotus aIba Desr.) the cis and trans isomers of o-hydroxycinnamic acid occur primarily as the respective β-D-glucosides (Rudorf and Schwarze 1958; Kosuge 1961; Haskins and Gorz 1961a; Stoker and Bellis 1962). The review of Brown (1963) summarizes evidence that these glucosides are formed via the following pathway: phenylalanine (formed from shikimic acid) → trans-cinnamic acid → trans-o-hydroxycinnamic acid (o-coumaric acid) trans-β-D-glucosyl-o-hydroxycinnamic acid (o-coumaric acid glucoside) → cis-β-D-glucosyl-o-hydroxycinnamic acid (coumarinic acid glucoside). Sweetclover plants of the Cu Cu genotype contain substantial amounts of both …

Ultraviolet-Induced Isomerization Of Β-D-Glucosyl O-Hydroxycinnamic Acid On Filter Paper, Andris Kleinhofs, Francis A. Haskins, Herman J. Gorz

Department of Agronomy and Horticulture: Faculty Publications

Coumarinic acid glucoside (β-D-glucosyl cis-o-hydroxycinnamic acid) and o-coumaric acid glucoside (β-D-glucosyl &am-o-hydroxycinnamic acid) are readily detected as absorbing areas on filter paper chromatograms exposed to ultraviolet light at wavelengths near 260 mp. Long wavelength ultraviolet radiation is frequently used to detect fluorescent compounds closely related to these two glucosides. The foregoing facts prompted this investigation concerning the influence of both long and short wavelength ultraviolet light on small amounts of coumarinic acid glucoside and o-coumaric acid glucoside, air-dried on filter paper strips. Ultraviolet-induced interconversion of these two isomers in aqueous solutions is well known.

Where Is Moly?, A. L. Hatfield

Agronomy Notes

Is moly in hiding or has it gone down the river? Recent tests in Graves County suggest that it is probably just in hiding.

Moly (molybdenum) is of importance to Kentucky farmers because of its unique relation to soil acidity and legume growth. Many other trace or minor elements necessary for plant growth are most available to crops under acid soil conditions. Molybdenum becomes more available as the soil acidity approaches neutrality.

Agronomy Notes, No. 32, S. H. Phillips

Agronomy Notes

Silo Fillers Disease, caused by nitrogen dioxide, was discussed in a joint Agronomy and Pharmacology release. Dr. Mark Luckens, College of Pharmacy, has prepared strips of potassium iodide - starch test paper to assist in detecting this deadly gas in silos and feeding areas. These strips are small (5/8" x - 2") and change to a blue color when in contact with nitrogen dioxide. We have 300 strips available for use by County Agents.

Agricultural Limestone In Kentucky, George D. Corder

Agronomy Notes

Kentucky farmers invested about $6 million in agricultural limestone in 1964. However, much more lime than this should have been used if farmers get the most economical crop production and the most efficient use of fertilizers that are applied or the fertility that is already in the soil.

Summer Soil And Air Temperatures In Four Plant Communities, Paul W. Conrad

Theses and Dissertations

Temperature, one of the most influential factors controlling the growth and distribution of plants, was measured during a three month summer period within several stands of vegetation. The stands represented four distinct plant communities: sagebrush-grass, mountain brush, aspen, and conifer. Measurements were obtained by a sucrose inversion method which gave exponential average or effective mean temperature (eT) values. Registerants, small glass vials filled with a sucrose-buffer solution, were placed in the air 10 decimeters above the ground level and in the soil 1, 5, and 10 decimeters below the ground level. The sites were carefully described with respect to plant …

Plant Communities: Native Vegetation Of Nebraska, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Thanks to our rapid increase in population ,and the largely indiscriminate spread of urban, industrial, and transport facilities, the time is not far distant when land-use capabilities must receive much more attention than they have enjoyed. Natural, that is pre-settlement, vegetation, integrating as it did the manifold factors of environment, is un-excelled as a guide to potential land use.
