Airplane-Seeded Wheat – Aid To Double Cropping, John Watts, S. H. Phillips

Agronomy Notes

Airplane-seeding of wheat has been increasing since its start in 1965 in Fulton County, Kentucky. Over 20,000 acres were seeded in the fall of 1968, with the acreage concentrated in the Purchase and Bowling Green areas.

Farmers report these advantages for aerial seedings: (1) early establishment of small grain; (2) similar seeding cost as compared to drilling; (3) labor use in normal seeding operations diverted to other farm operations.

What Happens To Fertilizer Nitrogen In The Soil?, W. O. Atkinson, John L. Ragland

Agronomy Notes

What happens to the nitrogen a farmer applies as fertilizer each spring?

First, let us consider the forms of nitrogen normally applied, and then attempt to trace what happens to the nitrogen once it is added to the soil. The average complete fertilizer contains approximately 70 percent of its nitrogen in the ammonium nitrogen form (NH4), about 10 percent in the urea form (this is quickly converted to ammonium nitrogen), and the remaining 20 percent in the nitrate nitrogen form (NO₃) .

Kenblue Kentucky Bluegrass, Robert C. Buckner

Agronomy Notes

Since the early 19th century the Blue Grass Region of Kentucky has had a worldwide reputation for its Kentucky bluegrass (Poa pratensis L.) As early as 1835, people from adjoining states visited the region to see its luxuriant fields and to learn of the culture and management of this valuable grass. This interest has led to the development of a profitable seed industry in central Kentucky. Kentucky produced the bulk of Kentucky bluegrass seed for the nation during the latter half of the 19th and the first half of the 20th centuries.

Since 1960, foreign importation and competitive production of …

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

INSECT pests have been taking toll of mans' crops and herds since very early times and despite modern control techniques the annual loss is still very high.

It has been estimated that damage to stored grain alone may average 10 per cent, per year, or, in terms of the West Australian harvest, a loss by weevils of about twice the capacity of the large Midland Junction bin.

Response Of Corn To Broadcast Applications Of Zinc, Harold F. Miller

Agronomy Notes

Where zinc deficiency in corn occurs on Kentucky soils it has been corrected by applying 3 to 6 pounds of elemental zinc per acre in the row at planting time. In some areas of the state, corn planters with row fertilizer attachments are not generally used, raising the question as to library the amount of zinc required when broadcast applications are made.

Through the cooperation of Clarence Mitchell, Area Extension Specialist, a field was located where the 1966 corn crop showed zinc deficiency. Since the field was to be planted in corn (Connecticut 860) in 1967, a field trial with …

Amsinckia Or Yellow Burr-Weed (Amsinckia Spp.), G R W Meadly

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

YELLOW BURR-WEED is widely established in the Wimmera and Mallee districts in Victoria, presumably introduced with fodder brought to this country from the United States about 1914.

It is a problem in Oregon and other north west wheat areas of America.

The weed is also widespread in New South Wales, being most troublesome in the wheat-growing sections of the Riverina. It is not established to the same extent in South Australia and Queensland.

The recent discovery of areas infested with yellow burr-weed at Merredin prompted the Agriculture Protection Board to declare it a primary noxious weed for Western Australia.
