Punched Cards as Aids in Evaluating Seedlings in the Field

Abstract

All systems devised to assist in taking the analyzing field notes for evaluating seedlings of fruits have some disadvantages, but some have marked advantages. Circling or underlining printed descriptions and ratings on a 3 × 5 inch card is perhaps the simplest and easiest method of recording detailed field notes on seedling populations. The cards are of convenient size for handling and storing. After the notes have been taken, however, the painstaking and sometimes prohibitive task of analyzing is the logical solution. One can hand-transfer all the information from field cards to punched cards or tapes; but this involves an extra step and the accompanying chance for error.
