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
Nebraska Agricultural Experiment Station: Historical Research Bulletins
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 …
