G80-526 The Effect Of Weather On Corn: Preseason Precipitation And Yield Of Unirrigationed Corn, Ralph E. Neild

Historical Materials from University of Nebraska-Lincoln Extension

This NebGuide examines the results of studies done on the effects of weather on unirrigationd corn.

Studies of the effects of weather on unirrigationd corn in Nebraska between 1950 and 1974 show the following four factors to be closely related to yield:

Technology--the availability of better hybrids, nitrogen fertilizer, herbicides, insecticides and other improvements have resulted in a yield increase averaging 1.3 bushel per acre per year since 1950.

Preseason precipitation--that which occurred between September 1 and May 15 had a beneficial effect. Yield increased on the average of 1.1 bushel per acre for each inch that preseason ...

Tests indicate which varieties of oats, barley and spring wheat are best adapted to Nebraska growing conditions. The primary spring small grain grown in Nebraska is oats. Oats are grown throughout the state, but production is concentrated in the east and northeast cropping districts. Nebraska's estimated harvested oat acreage in 1989 was 310,000 acres. Spring barley production is centered in the northwest and southwest districts. Harvested barley acreage in 1990 was 30,000 acres. Barley is commonly grown as an early summer feed grain and corn substitute. Spring wheat production in Nebraska is concentrated in the northern section ...

Historical Materials from University of Nebraska-Lincoln Extension

The growth and control of Canada thistle is covered here.

Canada thistle plant

Canada thistle [Cirsium arvense (L) Scop.] is a native of Eurasia and was probably introduced to America around 1750. Since that time it has spread throughout the northern part of the United States. Canada thistle is estimated to infest 800,000 acres in northern and western Nebraska.

A perennial that reproduces from seed and by an extensive root system, Canada thistle is dioecious, with the male and female flowers on separate plants. For viable seed to be produced, both male and female plants need to be present.
