Progress From Recurrent Selection Procedures For The Improvement Of Corn Populations, John H. Lonnquist

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The possibilities of developing synthetic varieties suitable for the fringe areas of the corn belt, where cost of hybrid seed is high relative to the value of the expected crop, and in areas where hybrid corn might not be a feasible approach for other reasons, made it seem a worthwhile objective for study. Effort has been made in recent years to increase the productivity of hybrid combinations through selection of new superior lines using standard breeding procedures. The limited progress realized has resulted in an increased interest in the possible use of alternate methods for the development of superior germplasm …

The Use Of Nitrogenous Fertilisers For Cereal Grain Production In Western Australia, William John Toms, G. H. Burvill

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

NITROGENOUS fertilisers have so far been little used in Western Australia for wheat, oats and barley grown for grain.

However, profitable results can follow their use under some conditions. Farmers who have seen field experiments are now interested in the use of nitrogenous fertilisers.Further interest will be stimulated by recent reductions in price.

This article answers common questions asked by farmers about nitrogenous fertilisers for cereals. It is based on over 100 experiments conducted by the Department of Agriculture during the past 30 years.

Spread Super For Cereal Crops, T E. Mcdowell, J. A. C. Smith, W. J. Toms, M. D. Carroll

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

THE use of bulk superphosphate broadcast direct on to the paddocks is a new method of reducing fertiliser costs.

But it has long been known that broadcasting phosphate is less efficient than drilling it in with the seed.

The experiment reported here was designed to demonstrate this point.

Microorganisms And Soil Structure, T. M. Mccalla, F. A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

SUMMARY

Good stable soil structure is valuable for promoting the growth of plants and micro-organisms by permitting enhanced aeration and water penetration and by decreasing erosion under some conditions.

Micro-organisms influence water percolation through the soil. They may plug up soil pores with byproducts of growth and reduce water percolation. On the other hand, if a soil containing a large amount of microbial products is stirred and allowed to dry, then the percolation may be high.

Micro-organisms are involved in stabilizing soil structure by their products of decomposition and their cellular binding material, such as mycelia. Microorganisms differ greatly in …

Pensternon In Your Garden, Glenn Viehmeyer

Department of Agronomy and Horticulture: Faculty Publications

A new race of hardy perennials is beginning to appear in American gardens. These are the penstemons, a genus of plants closely related to the familiar snapdragon, which may become important ornamentals as they become better known to gardeners. The purpose of this bulletin is to show the possibility of the genus as an ornamental and to suggest species and species hybrids of possible value to Great Plains gardeners; to provide information about propagation and culture; and to encourage gardeners to engage in penstemon breeding as an avocation.

Genetic Studies Of Winter Hardiness In Barley, C. R. Rohde, C. F. Pulham

Nebraska Agricultural Experiment Station: Historical Research Bulletins

An important obstacle toward the development of winter barley varieties with a higher level of winter hardiness has been the deficiency of genetic information on this character. The primary objective of these studies was to obtain information on the genetics of the winter hardiness of a group of 18 winter barley varieties which originated from widely different geographic areas of the world. It was hoped that this information might be helpful in determining whether or not it would be possible for barley breeders to combine different genetic sources of winter hardiness and attain a higher level of hardiness than presently …

The Development Of Western Australian Sand Plain Soils For Agriculture, Richard Philip Roberts, F. L. Shier

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

IN a recently published economic survey of the Australian wheat growing industry, it was reported that nearly two-thirds of the farms surveyed in Western Australia were located on lateritic "sand plain."

As a random selection was made of the eighty farms that were visited it is reasonable to conclude that a similar proportion of all the State's wheat producing farms are on that type of country.

This constitutes a remarkable change from the earlier days of wheat belt settlement when the sand plain soils were regarded as virtually useless and by-passed for development.

It is the purpose of this article …

Kimberley Research Station : A Progress Report, Department Of Agriculture, Western Australia

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

INTEREST in the agricultural potential of the Kimberley region in Western Australia dates from its early exploration and settlement in the last century.

Several farming development schemes were considered for the area, but were never implemented.

This could be mainly attributable to lack of knowledge of agricultural potentialities, limitations of the local environment and ways of exploiting the local environment.

Up to the present the economy of the region is almost entirely based upon the extensive production of beef and to a lesser extent, wool.

The Effect Of Inbreeding Diallel Crosses Of Inbred Lines Of Corn Selected For High And Low Combining Ability, Melvin Dale Rumbaugh

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

The present day hybrid seed corn industry is based upon the development and utilization of inbred lines in hybrid combination. Current breeding procedures are largely predicated on the assumption that the actions of complementary, dominant or partially dominant favorable genes are responsible for the heterosis observed in the hybrids produced. If heterosis were due in considerable part to nonallelic interactions or to overdominance, the present breeding procedures might be expected to yield superior hybrids but would not be highly efficient.

Since the proposal of complementary growth factors as a genetic explanation of heterosis and the alternative proposal of physiological stimulation …

Effect Of Time Of Cutting On Yield And Botanical Composition Of Prairie Hay In Southeastern Nebraska, Elverne C. Conard, Vincent H. Arthaud

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Approximately three and one-third million acres of native prairie are harvested annually in Nebraska for hay. In the four-year period 1948-1951, the State ranked first in wild hay production with an average yield of more than two and one-quarter million tons per year. This crop is an important natural resource in Nebraska's livestock industry. Studies were initiated in 1945 to determine the effects of time of cutting on the yield and feeding value of prairie hay in southeastern Nebraska. The studies were continued through the summer of 1952 to determine the effects of different cutting treatments on the vigor and …

Rate Of Potato Tuber Growth On Dryland At The Box Butte Experiment Farm, H. O. Werner

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Relatively late planting of potatoes, i.e., between June 12 and 25, has become the prevailing practice in the dryland areas of western Nebraska. Late planting distinctly improves the color and type of tubers, and reduces losses due to insects and diseases (especially soil-borne diseases caused by Fusarium and Streptomyces). Growers must decide each year whether the increase in yield and tuber maturity gained by delaying harvest will be offset by the risk of impaired tuber quality due to scab or possible serious field frost damage. Information about the rate at which tubers are developing by various dates is essential …
