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 …
Price, Yield And Net Income Variability For Selected Field Crops And Counties In Nebraska, Boris E. Bravo-Ureta, Glenn A. Helmers
Price, Yield And Net Income Variability For Selected Field Crops And Counties In Nebraska, Boris E. Bravo-Ureta, Glenn A. Helmers
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The primary objective of this study was to establish an empirical estimate of the riskiness of various crops in different regions of Nebraska. For this purpose the variate difference method was used to estimate random variability indexes of prices, yields, and net returns for six Nebraska crops (wheat, soybeans, alfalfa, oats, grain sorghum, corn). The period of analysis included 1957-1976 and one county in each of the eight crop reporting districts was analyzed. Where relevant, both dryland and irrigated alternatives were examined. Most business decision-makers accept more risk only under the conditions that the probability of higher returns accompany risky …
Profit Maximizing Farm Plans For Farms In Southeastern Nebraska: By Type And Size Of Farm, M. D. Skold, A. W. Epp, H. W. Hughes
Profit Maximizing Farm Plans For Farms In Southeastern Nebraska: By Type And Size Of Farm, M. D. Skold, A. W. Epp, H. W. Hughes
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
There are many forces operating in today's agricultural economy which cause farmers to examine carefully their patterns of resource allocation. Rising production costs coupled with downward tendencies in product prices focuses attention on efficient patterns of resource allocation. Technical change and changing resource and product price relationships affect efficient resource allocation patterns. This study considers possible efficient farm organizations available to farmers in southeastern Nebraska with given resources. The study determines profit maximizing farm plans for farm classes with different complements of resources and at alternative product price levels. Both crop and livestock enterprises are considered. Investment activities that generate …
The Influence Of Acreage And Yield Changes On Crop Production In Nebraska, Robert M. Finley
The Influence Of Acreage And Yield Changes On Crop Production In Nebraska, Robert M. Finley
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The general purpose of the study is to assess the impact of acreage and yield changes on total production of important Nebraska crops. A secondary purpose is to examine two different methods of imputing the influence of changes of yield and acreage on production changes.
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.
Fusarium Blight Of The Soy Bean And The Relation Of Various Factors To Infection, Richard O. Cromwell
Fusarium Blight Of The Soy Bean And The Relation Of Various Factors To Infection, Richard O. Cromwell
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
An investigation was outlined (1) to determine the parasitism of Fusarium on soy bean, (2) to establish its relationship to Fusaria of the section Elegans in so far as a comparison of the cultural characters permitted, and (3) by means of cross- inoculations and field studies to determine the relationship of this disease of soy beans to the wilt disease of cowpeas (Vigna sinensis Hassk.) caused by Fusarium tracheiphilum Smith. The results of these investigations up to the close of the summer of 1916 have been reported. The studies were continued at the North Carolina Experiment Station until the …
