THE EXPERIMENTAL FIELD, THE BASIS OF SCIENTIFIC RESEARCH IN AGRICULTURE

Abstract

Scientific research in agriculture generally aims to increase the production quality yield and has as its basis the experimental field in which the results performed in the laboratory or in other conditions receive confirmation of the experiments performed in the field under natural conditions. The permanent character of the scientific research in agriculture allows the obtaining of new varieties of more productive, superior quality plants and the necessity to experiment and to introduce in production new specific technologies. The experimental field is an effective means of guidance for production specialists. It has an educational significance, because those working in agricultural production can be convinced of the effectiveness of the latest developments in the field of agricultural sciences through practical demonstrations. The selection of the field for the experimental field is made in ecologically representative areas for the group of species or varieties of study. The soil should be homogeneous and uniform in terms of relief and profile, elements which ultimately determine the uniformity of fertility. Considering that the uniformity of the soil in the experimental field is the main condition for obtaining quality results, the researchers must pay special attention to it, even resorting to the practice of "recognition cultures" or the "blind experiments" method.
