Abstract

There are stated methodic peculiarities of investigations in experiments with oil crops: the basis of the scientific cognition and a choice of directions of sci-entific researches, methods of scientific researches, planning and organization of an experiment. The basic elements of the methodology of a field experiment are described. There are presented observations and accounts in the field experiments with soybean: plant structure, growth, and development; phenology and biometrics; the diagnostic of mineral nutrition for soybean; the determination of elements of yield structure; the determination of a number and weight of nodules on plant roots; analytic observations in laboratory; yield account and the calculation of the consumption of nutrients, oil and protein yields, and seed yield. The article is based on a published book “Methodology of agricultural and chemical investigations in experiments with oil crops” by Lukomets V.M., Tishkov N.M., and Semerenko S.A. (Krasnodar, 2022).
