Results Of The Sixth International Winter Wheat Performance Nursery Grown In 1974, K. D. Wilhelmi, S. L. Kuhr, V. A. Johnson, P. J. Mattern, J. W. Schmidt Dec 1976

Results Of The Sixth International Winter Wheat Performance Nursery Grown In 1974, K. D. Wilhelmi, S. L. Kuhr, V. A. Johnson, P. J. Mattern, J. W. Schmidt

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This is the sixth report of results from an International Winter Wheat Performance Nursery (IWWPN) organized in 1968 by the Nebraska Agricultural Experiment Station and the Agricultural Research Service, U. S. Department of Agriculture, under a contract with the Agency for International Development, U.S. Department of State. The Nursery was designed to (1) test the adaptation of winter wheat cultivars in a range of latitudes, daylengths, fertility conditions, water management, and disease complexes; (2) identify superior winter cultivars to serve as recipient genotypes for high protein and high lysine genes, and (3) test the degree of expression and stability of …


Effects Of Time Of Application Of Glyphosate In The Control Of Johnsongrass, Marlin Moody Dec 1976

Effects Of Time Of Application Of Glyphosate In The Control Of Johnsongrass, Marlin Moody

Masters Theses & Specialist Projects

Investigations were conducted to determine the effects of the herbicide glyphosate and its time of application on the control of johnsongrass.

Johnsongrass plots were divided into areas designated undisturbed, spring plowed, and clipped. These areas were compared to determine differences in control of johnsongrass when using glyphosate with different management procedures. Glyphosate was applied at weekly intervals and treatment effects were statistically analyzed. There were three replications of each treatment.

It appears from the results that:

  1. Glyphosate kills approximately 100% of the johnsongrass topgrowth regardless of the application date.

  2. Height of the johnsongrass plant at the time of glyphosate application …


Evaluation Of Glyphosate In No-Till Double Crop Soybeans Using Varying Volumes & Pressures, Charles Rogers Dec 1976

Evaluation Of Glyphosate In No-Till Double Crop Soybeans Using Varying Volumes & Pressures, Charles Rogers

Masters Theses & Specialist Projects

No-tillage production of crops has developed and become widespread since the late 1950/s. No-till is dependent upon the use of broad spectrum herbicides to kill weeds already growing at planting time. Until recently, this has almost exclusively been paraquat (1,1'-dimethy1-4,4'-bipyridinium ion). Glyphosate [N-(phosphonomethyl)glycine] is a new herbicide which has great potential for use in no -tillage production.

Soybeans (Glycine max L.) were planted in the stubble after wheat (Triticum aestivum L.) was harvested. All plots received applications of the residual herbicides alachlor [2-chioro-2',6'-diethyl-N-(methoxymethyl)acetanilide] and linuron [3-(3,4-dichlorophenv1)-1-methoxy-1-methylurea]. Each plot also received either paraquat or glyphosate or was designated as …


Performance Of Certified Seed Lots Of Dawson Alfalfa, W. R. Kehr, G. R. Manglitz Aug 1976

Performance Of Certified Seed Lots Of Dawson Alfalfa, W. R. Kehr, G. R. Manglitz

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Breeder, foundation, and certified seed lots of Dawson alfalfa, Medicago sativa L., were tested to determine stability in performance during three generations of seed increase under certification. Two field experiments were conducted, a seeded forage yield test and a space-planted test. Greenhouse experiments included separate tests for resistance to pea aphids, spotted alfalfa aphids, and bacterial wilt. Results obtained on certified Dawson alfalfa seed classes in field and greenhouse experiments were in agreement with the original variety description.

Facility Costs Of Centralized Grain Storage Systems Utilizing Computer Design, Otto J. Loewer Jr., Thomas C. Bridges, Douglas G. Overhults Jan 1976

Facility Costs Of Centralized Grain Storage Systems Utilizing Computer Design, Otto J. Loewer Jr., Thomas C. Bridges, Douglas G. Overhults

Biosystems and Agricultural Engineering Faculty Publications

The item considered most often when estimating the cost of a grain storage facility is capacity. Of equal or greater importance is daily harvest rate. Other important considerations include drying method, materials handling equipment, energy cost, facility arrangement, labor requirements, grain quality and management ability. Only through a comparison of facilities which offer similar capacity, capability and convenience can the purchaser obtain his best system.


Comparison Of Economic Returns From Grain Crops, H M. Fisher Jan 1976

Comparison Of Economic Returns From Grain Crops, H M. Fisher

Journal of the Department of Agriculture, Western Australia, Series 4

While wheat is still generally the most profitable crop in Western Australia the relative profitability of barley and linseed has risen in the last few years; in southern areas they are likely to be at least as profitable as wheat.

Oats has fallen in profitability relative to wheat, and grain legumes have suffered a marked fall. Yields of these grains have increased with the introduction of new varieties but their price increases have not kept pace with those of wheat and barley. The present relationship of yields and costs indicates that substantial price changes will be needed to change the …

Aspen Forest After Harvest, Norbert V. Debyle Jan 1976

Aspen Forest After Harvest, Norbert V. Debyle

Aspen Bibliography

Aspen is a unique forest tree with respect to regeneration. It produces abundant root suckers, up to 40,000 per acre are common, after clearcutting or fire removes the parent stand. The rapidly growing sucker stand competes well with other vegetation, but is susceptible to destruction by excessive ungulate browsing. Clearcut areas produce more streamflow and more growth on shrubs and herbaceous vegetation than does the uncut forest. The patchwork of age classes that results from even-age management optimizes wildlife habitat requirements for several desired species.
