Feeding Beets And Potatoes For Butter, James Wilson, F. A. Leighton, D. B. Bisbee

Bulletin (Iowa Agricultural Experiment Station)

The farmers of Iowa are growing sugar beets to learn the adaptation of the soils and climates of the state to sugar production. The feeding value of the beet entire without the sugar extracted, is a matter of interest to them.

The crop of potatoes in 1891 was large, and where they were unsalable owing to remoteness from markets, or for other causes, it became interesting to ascertain feeding values for dairy products.

In conformity with inquiries concerning these subjects, this station fed four cows during three months, beginning December 1st, 1891, and ending February 29, 1892.

Microbial Ecology Electronic Resources, Michael Bobb

Michael Bobb

Microbial ecology covers sub-disciplines of both microbiology and ecology. To put it briefly, it is the study of the roles and relationships that microorganisms (predominantly bacteria and fungi) have with the environment and other organisms within the environment. There is much overlap in the topic areas, and often research covers several different sub-disciplines simultaneously. Major topic areas within microbial ecology are ecology, microbiology, soil science, agriculture, bioremediation, environmental science, biogeography, biogeochemistry, oceanography, restoration ecology, and dentistry/biofilm biology. Researchers and research programs cover a broad spectrum of topics; for example, molecular researchers who are interested in the metabolic processes and ...

Positioning Of The Scrambled Receptor Requires Udp-Glc:Sterol Glucosyltransferase 80b1 In Arabidopsis Roots, Victoria G. Pook, Meera Nair, Kookhui Ryu, James C. Arpin, John Schiefelbein, Kathrin Schrick, Seth Debolt

Horticulture Faculty Publications

The biological function of sterol glucosides (SGs), the most abundant sterol derivatives in higher plants, remains uncertain. In an effort to improve our understanding of these membrane lipids we examined phenotypes exhibited by the roots of Arabidopsis (Arabidopsis thaliana) lines carrying insertions in the UDP-Glc:sterol glucosyltransferase genes, UGT80A2 and UGT80B1. We show that although ugt80A2 mutants exhibit significantly lower levels of total SGs they are morphologically indistinguishable from wild-type plants. In contrast, the roots of ugt80B1 mutants are only deficient in stigmasteryl glucosides but exhibit a significant reduction in root hairs. Sub-cellular investigations reveal that the plasma membrane cell ...

Hints For Beginners In Dairying, F. A. Leighton

Bulletin (Iowa Agricultural Experiment Station)

The first and most essential requirement is to teach the patrons how to take care of the milk. Everything about the dairy that the milk comes in contact with should be of tin. The milk should be thoroughly cooled and aereated immediately after it is drawn from the cow to prevent souring. In winter it should be kept in a cool room. In summer it should be set in cold water until the collector calls for it. The delivery cans should be washed out with warm water in which some sal soda has been dissolved, then scalded and rinsed in ...

What To Plant On The Home Grounds, J. L. Budd

Bulletin (Iowa Agricultural Experiment Station)

The Station correspondence has many queries in regard to selection of the most desirable shade and ornamental trees, shrubs, and small fruits, for the home grounds.

The appended notes give the results of long trial on the College grounds, supplemented by reports from intelligent amateurs in the north half of the state. At this time the selections are made specially for the parts of the state north of the 42d parallel, yet the few select varieties and species do well in all parts of the state.

Experiments With Fungicides, L. H. Pammel

Bulletin (Iowa Agricultural Experiment Station)

It is the general accepted opinion among botanists, that corn smut (Ustilago Maydis) enters the tissues of its host during the early stages of the growth of corn. These opinions are based on the careful experiments of Dr. Julius Kuehn, a German botanist.

Last spring some experiments were started on the College Farm with a view of preventing this troublesome disease. It was expected, of course, that the results at the close of the season would show a decided advantage when seed corn was treated, but to my surprise, the results were entirely negative. In the meantime a bulletin was ...

Corn Growing, C. F. Curtiss

Bulletin (Iowa Agricultural Experiment Station)

Five different varieties of corn were grown under varying conditions on the Experiment Station grounds during the past season, with a view to testing varieties, fertilizers, green manuring, and different methods of cultivation. The varieties grown were Mammoth Cuban, Early Mastodon, Red Cob Ensilage, King of the Earliest, and Capital.

The Mammoth Cuban and Red Cob Ensilage varieties were planted April 29th, the Early Mastodon on May 6th, and the King of the Earliest on May 7th, all on fall plowed ground, thoroughly cultivated and harrowed before planting, and rolled immediately after, as the soil was very dry. Scarcely any ...

Varieties Of Potatoes, C. F. Curtiss

Bulletin (Iowa Agricultural Experiment Station)

About two dozen varieties of potatoes were found in the Station root cellar at the beginning of last year. These with other desirable kinds were planted for a comparative test. A piece of ground that had at one time been the site occupied by a house and brick yard was planted with thirty varieties. The ground was not in good condition. Part of it had to be cleared of stumps, stones, and the remains of two brick kilns, a part was old stiff clay soil and the remainder was in blue grass and clover. When all cleared it gave a ...

Crop Report Of The Farm Department, D. A. Kent

Bulletin (Iowa Agricultural Experiment Station)

Following is a report on two fields of corn, a small field of barley and the storage of ensilage. We have attempted to tell just how we raised the crops, how much labor was applied, what the labor cost us and what the crops yielded. Eliminating as much theory as possible. There is a very wide difference of opinion among farmers about some of the methods of raising crops. These differences are settled best when every gentleman only describes his methods, accurately, and appends results. A comparison of these results will settle questions much more rapidly than vague theorizing over ...

Flax Seed Meal And Oil Meal, James Wilson, C. F. Curtiss, D. A. Kent

Bulletin (Iowa Agricultural Experiment Station)

This Station had so many inquiries during the fall of 1891 regarding the relative feeding values of flax seed ground, and oil meal, that we concluded to ascertain for Iowa farmers something concerning the two feeds. At many places in the state a ton of flax seed sold as low as a ton of oil meal, and farmers who had grown flax and desired to feed cattle, were anxious to know whether they could feed it as it grows with the oil in it.

We were also asked how much flax meal could safely and economically be fed under different ...

Fertilizers

Bulletin (Iowa Agricultural Experiment Station)

Reports on several experiments are deferred until February when our next bulletin will be issued. We acknowledge with gratitude the donation of Mr. C. B. Souter, of Cedar Rapids, of two tons of slaughter house tankage fertilizer for experiment in growing crops. We have used numerous fertilizers on different crops during the past season, but will repeat all o f them before publishing indications.

Best Varieties Of Oats, James Wilson, C. F. Curtiss, D. A. Kent

Bulletin (Iowa Agricultural Experiment Station)

With a view to ascertaining what varieties of oats are best adapted to our soil and climate, eleven of the most promising 'varieties that could be obtained were grown for a comparative test as to yield, quality and ability to withstand attacks of rust and other diseases. The ground used was a piece of fall plowed corn ground, harrowed once before sowing and twice afterward. The soil was sandy loam and had been under cultivation for a number of years. The seeding was done early, April 8th and 10th, and the soil was too wet to admit of the use ...

Winter Wheat, James Wilson, C. F. Curtiss, D. A. Kent

Bulletin (Iowa Agricultural Experiment Station)

Fourteen varieties of winter wheat sown by director Speer,, were found growing on the Station grounds when we took charge in January. Eight varieties, viz.: The Hybrid Lamed, Hybrid Dattel, "Found in Golden Cross," Pool, Jones White Fife, Early Red Clawson, Turkish Red, and Golden Cross, were grown on fair sized plats (averaging about one-fourth of an acre), but the remaining six, viz. : The Johnson, Willits, Roberts, Bailey, and Stewarts, were grown on areas too small for a very satisfactory test. All varieties had been sown between the dates of September 5th and 15th, on what appeared to have been ...

Time Of Sowing Grass Seed, James Wilson, C. F. Curtis, D. A. Kent

Bulletin (Iowa Agricultural Experiment Station)

For the purpose of ascertaining the best time to sow the seeds of cultivated grasses this station sowed the seeds of six different grasses at eight different times beginning March 23 and ending May 12, 1891. The varieties sown were red clover, white clover, timothy, orchard grass, tall meadow oat grass and awnless brome (bromus inermus). The plats are one rod square. The soil is rolling prairie with black surface and clay subsoil, fall plowed. The amount sown were, red clover and timothy at the rate of 20 pounds per acre, white clover 10 pounds per acre, tall meadow oat ...

Soiling Experiment, James Wilson, G. E. Patrick, C. F. Curtis, D. A. Kent

Bulletin (Iowa Agricultural Experiment Station)

The losses that occur annually to our farmers from the drying up of their pastures in July, August, and September, induced us to grow a few acres of green feed, and ascertain to what extent such feed, of different kinds, can be had from an acre of land; how much a cow requires of each kind, and the effect of such feeding on quantity and quality of milk, compared with well watered, well shaded, good blue grass pastures.

Our dairies are mostly idle because the cows have gone dry. and the cows have gone dry because their pastures have failed ...

Reports On Injurious Insects, Herbert Osborn, H. A. Gossard

Bulletin (Iowa Agricultural Experiment Station)

A short time since Prof. Curtiss informed us that Mr. Dana Reed, of Coon Rapids, had given him some beetles that were eating into the ears of corn, and from his description it was inferred that they were the common Indian Cetonia (Euphoria inda), which has in a few instances heretofore been reported as doing damage of this character. The beetles proved, as suspected, to be this species, and in view of the uncertainty as to the possibility of this species to do damage of this kind it seemed desirable to get as much data as possible and to make ...

Fungus Diseases Of Sugar Beet, L. H. Pammel

Bulletin (Iowa Agricultural Experiment Station)

There is no doubt that intensified culture of the sugar beet has made it much susceptible to the attacks of animal and vegetable parasites. In Europe parasitic diseases of the sugar beet are much more numerous than in this country. Several have long been known to cause serious injury to sugar beet culture.

European growers have long been accustomed to ascribe certain diseased conditions to soil exhaustion. The term “beet sickness” has been given to a large number of poorly defined diseases. Practical growers believe that want of potash or phosphates causes this condition. From the very exhaustive researches of ...
