A Cropping System For Intensive Grain Production On Sloping Land, Kenneth L. Wells, H. C. Vaught, Morris J. Bitzer, M. W. Russell

Agronomy Notes

From the beginnings of Kentucky Agriculture, soil erosion and related losses in productivity have been major problems for Kentucky farmers. Improved soil conservation practices during the past forty years have been especially significant in the recovery and progress of our agricultural industry. No-tillage methods for crop production, which were pioneered in Kentucky, have proven useful in controlling erosion and holding production at high levels. During recent years, the marketplace has strongly encouraged grain production, with the unfortunate effect that many Kentucky hillsides have been returned to grain production without sufficient erosion control measures. This report describes innovations in use of …

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

University of Nebraska-Lincoln Extension: Historical Materials

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 precipitation was …

G80-513 Protect Soil With Vegetative Residues, C,R, Fenster

University of Nebraska-Lincoln Extension: Historical Materials

Keeping a protective cover of vegetative residues on the soil surface is the simplest and surest way to control both water and wind erosion.

Crop residues are vital to conservation of soil and water. Keeping a protective cover of vegetative residues on the soil surface is the simplest and surest way to control both water and wind erosion. Vegetative residues on the soil surface improve infiltration of water into the soil, reduce evaporation, and aid in maintaining organic matter. Residues left upright all winter trap snow which increases soil water.

G80-496 Tomatoes In The Home Garden, Laurie Hodges, Dale T. Lindgren, Susan Schoneweis

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide outlines tomato rearing practices, cultivars and possible pest, disease and weed control problems.

Tomatoes come in a wide range of fruit colors, sizes, shapes and maturities. Ripe tomatoes may be red, yellow, orange, pink or even green. Shapes vary from globe or round to slightly flattened, pear-like or cherry-sized. Often consumers complain tomatoes purchased in grocery stores are lacking in flavor or have tough skin. In a home garden, you can grow the tomatoes you prefer, including a wide selection of fruit colors, flavors, textures and sizes. Although rumored, there is no direct link between fruit acidity and …

Effects Of Annual Burning On Grassland In The Aspen Parkland Of East-Central Alberta, Howard G. Anderson, Arthur W. Bailey

Aspen Bibliography

Annual early spring burning has markedly altered the physiognomy and species composition of aspen parkland vegetation of east-central Alberta. Burning was conducted in April for at least 24 years when soil moisture was normally high. The number of herbaceous species per quadrat doubled while a number of woody species declined slightly.
