Soybean Chlorosis Studies On High Ph Bottomland Soils, E. J. Penas, R. A. Wiese, R. W. Elmore, G. W. Hergert, R. S. Moomaw
Soybean Chlorosis Studies On High Ph Bottomland Soils, E. J. Penas, R. A. Wiese, R. W. Elmore, G. W. Hergert, R. S. Moomaw
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Soybean varieties are different in tolerance to lime-induced chlorosis. Field trials were conducted to evaluate variety performance on soils where chlorosis in soybeans was a known problem. Thirty-six varieties out of 177 were identified as tolerant to soil conditions that cause chlorosis. Eleven varieties of these 36 were found to have the most consistent yield performance on high pH soils. Tolerant varieties must be planted at adequate densities for best performance. A seeding rate of 13.5 seeds per foot of row, the highest seeding rate employed, did not appear to maximize yield on soils where chlorosis was severe. On some …
Results Of The First International Winter Wheat Performance Nursery, J. E. Stroike, V. A. Johnson, J. W. Schmidt, P. J. Mattern
Results Of The First International Winter Wheat Performance Nursery, J. E. Stroike, V. A. Johnson, J. W. Schmidt, P. J. Mattern
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The International Winter Wheat Performance Nursery was organized by the Nebraska Agricultural Experiment Station and the Agricultural Research Service, U.S. Department of Agriculture, under a contract with the Agency for International Development, U.S. Department of State. There has been informal cooperation with the Food and Agriculture Organization, United Nations, and the International Maize and Wheat Improvement Center (CIMMYT), Mexico, D. F. Specific objectives of the nursery are to: (1) Test the adaptation of winter wheat varieties under a range of latitudes, daylengths, fertility conditions, water management and disease complexes (2) Identify superior winter varieties to serve as recipient genotypes for …
Performance Evaluation Of Some Warm-Season Prairie Grasses In Nebraska Environments, D. D. Warnes, L. C. Newell, W. J. Moline
Performance Evaluation Of Some Warm-Season Prairie Grasses In Nebraska Environments, D. D. Warnes, L. C. Newell, W. J. Moline
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Objectives of these experiments were to study and compare establishment of stands, fertility responses, and forage yields of certain warm-season grass varieties and experimental strains in Nebraska locations which differed in soil and climatic conditions.
Cellar And Cold Storage Of Sound And Mechanically Damaged Triumph Seed Potatoes, H. O. Werner
Cellar And Cold Storage Of Sound And Mechanically Damaged Triumph Seed Potatoes, H. O. Werner
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The object of these experiments was to determine with practically sound, whole potatoes the effect of cold storage during various portions of the storage period and continual cellar storage upon: (a) the weight losses during numerous intervals of storage period; (b) the condition of the potatoes at the end of the storage period in June; and (c) the relative seed value of the various lots of potatoes as determined by field experiments.
The Regional Adaptation Of Corn In Nebraska, T. A. Kiesselbach, F. D. Keim
The Regional Adaptation Of Corn In Nebraska, T. A. Kiesselbach, F. D. Keim
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The purpose of this investigation was to determine some of the factors involved in the regional adaptation of corn. The procedure has been to make a comparative study of native corn types, known to be locally adapted to various regional areas in Nebraska through long growth there. The work has been confined to the single species group - Zea mays indentata. No one variety of a common source is grown throughout the state, and therefore it has been impossible to keep within a single variety. It would appear that the data should indicate morphological and histological plant characteristics involved …
Freezing Injury Of Seed Corn, T. A. Kiesselbach, J. A. Ratcliff
Freezing Injury Of Seed Corn, T. A. Kiesselbach, J. A. Ratcliff
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The object of the investigations in this bulletin has been to determine the conditions under which freezing injury may occur to seed corn; to indicate, if possible, the vital changes in the embryo resulting in such injury; and to point out ways by which seed corn of strong vitality and satisfactory yielding capacity may be obtained.
Studies Concerning The Elimination Of Experimental Error In Comparative Crop Tests, T. A. Kiesselbach
Studies Concerning The Elimination Of Experimental Error In Comparative Crop Tests, T. A. Kiesselbach
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
It is apparent that many sources of error have unconsciously entered into comparative crop yield tests. The very important matter of overcoming variation in soil conditions as a source of experimental error has been quite extensively studied and reported by various investigators during the past decade. The means suggested for reducing such error have been (1) repetition of plats and (2) correction of yields according to check plats planted to a uniform variety or treatment at stated intervals. Both methods have proved of value and a combination of both may often be used advantageously. Some danger always exists of error …
