Date Of Planting Studies Of Winter Wheat And Winter Barley In Relation To Root And Crown Rot Grain Yields And Quality, C. R. Fenster, M. G. Boosalis, J. L. Weihing
Date Of Planting Studies Of Winter Wheat And Winter Barley In Relation To Root And Crown Rot Grain Yields And Quality, C. R. Fenster, M. G. Boosalis, J. L. Weihing
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
This study was undertaken to determine the nature of root and crown rot of wheat and to ascertain the proper time to plant winter wheat so as to conserve moisture, minimize root and crown rot and thereby maximize yield. Studies conducted for 15 years at several locations in western Nebraska reveal that planting date is a significant factor for higher yields, particularly in certain years.
Yields In Different Cropping Systems And Fertilizer Tests Under Stubble Mulching And Plowing In Eastern Nebraska, F. L. Duley
Yields In Different Cropping Systems And Fertilizer Tests Under Stubble Mulching And Plowing In Eastern Nebraska, F. L. Duley
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The material in this report will be confined chiefly to studies on crop production with stubble-mulching compared with plowing. Major cash crops have been studied in different rotations including legumes and non-legume crops. In all tests, plowing has been compared with subsurface tillage. Different types of equipment have been devised and tested for the various operations during the course of these studies.
Influence Of Atmospheric And Soil Moisture Conditions On Diurnal Variations In Relative Turgidity Of Potato Leaves, H. O. Werner
Influence Of Atmospheric And Soil Moisture Conditions On Diurnal Variations In Relative Turgidity Of Potato Leaves, H. O. Werner
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The experimental work reported herein was planned to determine: 1. The extent and nature of the changes of the relative turgidity (R.T.) of leaves of the potato plant during the diurnal cycle. 2. The extent to which R.T. of potato leaves is influenced by atmospheric conditions, soil moisture, variety and age of plants. 3. The extent to which visible evidence of water shortage in leaves is indicative of water loss from them as revealed by R.T. and the extent to which this relationship varies with different varieties. 4. The nature of the relationships between morphological characteristics of leaves and stems …
Charcoal Rot Of Corn And Sorghum, J. E. Livingston
Charcoal Rot Of Corn And Sorghum, J. E. Livingston
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
In Nebraska, the charcoal rot caused considerable damage to the 1940 grain sorghum crop in the south central counties, and the following year it caused serious lodging and reduction of yield in both corn and sorghum in all sections of the state. Field observations indicated that some varieties of sorghum were damaged less than others; thus it appeared desirable to test thoroughly all varieties to determine whether any were sufficiently resistant to be recommended for field planting or to be used in a breeding program. It seemed desirable to study the influence of soil environment on infection and the development …
The Influence Of Various Soil Factors Upon Potato Scab Caused By Actinomyces Scabies, R. W. Goss
The Influence Of Various Soil Factors Upon Potato Scab Caused By Actinomyces Scabies, R. W. Goss
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Scab, caused by Actinomyces scabies (Thaxt.) Giiss., is a potato disease of major importance in western Nebraska. Seed treatments are effective in controlling seed-borne scab, but it has been shown that even when healthy or treated seed potatoes are used the disease may be very severe because of infection from the soil. Crop rotation will reduce the incidence of the disease, but the fact that potato scab may cause serious loss in soils never before planted to potatoes indicates that there are numerous factors other than the time interval between potato crops which affect the occurrence of the disease. A …
The Spindle-Tuber Disease As A Factor In Seed Potato Production, H. O. Werner
The Spindle-Tuber Disease As A Factor In Seed Potato Production, H. O. Werner
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The lines of experimentation that supplied the data herein reported, stated in very general terms, were as follows: (1) Tuber-line selection studies (2) Relation of environmental conditions to seed-potato production (3) Seed-potato strain trials of certified and uncertified stock (4) Spindle-tuber transmission experiments. Most of these general lines of experimentation will not be completely discussed as a unit in any one part of the bulletin. For the sake of clarity, consecutive thought, and elimination of repetition, data will be selected from any experiment for insertion and discussion under the most logical heading in any part of the bulletin. Unless otherwise …
Further Studies On The Effect Of Environment On Potato Degeneration Diseases, R. W. Goss, George L. Peltier
Further Studies On The Effect Of Environment On Potato Degeneration Diseases, R. W. Goss, George L. Peltier
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The identification of potato degeneration diseases in the field is extremely difficult owing to the number of diseases now described, their manifestation on different varieties, the combination of several diseases on the same plant, and the further splitting up of these combinations into separate diseases. The influence of environmental factors in intensifying or inhibiting the symptoms of these diseases also increases the difficulty of diagnosis. In the present investigation the effect of environmental factors has been studied with the purpose of determining the limiting factor or factors in the masking of the symptoms, in the hopes of simplifying a complex …
Relation Of Environment And Other Factors To Potato Wilt Caused By Fusarium Oxysporum, R. W. Goss
Relation Of Environment And Other Factors To Potato Wilt Caused By Fusarium Oxysporum, R. W. Goss
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The present work was undertaken to determine the influence of some environmental factors on the infection and progress of the disease potato wilt. The work has not progressed to the point of determining the exact relation of each of these factors. However, the results thus far obtained are presented here in order to direct attention to the nature and distribution of the disease in relation to the environmental conditions under which certain types of infection take place.
Studies Of The Etiology And Control Of Blister Canker On Apple Trees, J. Ralph Cooper
Studies Of The Etiology And Control Of Blister Canker On Apple Trees, J. Ralph Cooper
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The blister canker caused by Nummularia discreta Tul. is by far the most destructive disease of apple trees found in the United States. Serious damage due to this disease was first reported in Illinois in 1902. Since that time the disease has been reported to cause much damage in all apple-producing sections east of the Rocky Mountains. In Nebraska the disease is so prevalent that it is practically impossible to find an orchard free from it, and in many instances whole orchards have been destroyed thru its attacks. Because of the rapid dissemination and the destructive nature of blister canker, …
The Storage And Use Of Soil Moisture. Report Of Experimental Substation, North Platte, Nebraska, W. W. Burr
The Storage And Use Of Soil Moisture. Report Of Experimental Substation, North Platte, Nebraska, W. W. Burr
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The profitable cultivation of the non-irrigable lands in west central and western Nebraska is limited by the amount and efficient use of the precipitation. There are tracts of land in the sand hills and minor tracts of badly worn heavier soils where the need of soil fertility is becoming evident. But, in the main, the great problem at present is not one of soil fertility, but of how to get enough water to make use of the fertility now present. The rainfall of this section, which varies from an actual shortage to seldom more than a meager sufficiency, makes it …
