The perspectives of the herbal terpenoid application in yield increasing of agricultural products

The given article presents the results of the biological experiments in rice-growing and cotton growing, growth regulating activity of the ecologically safe raw of herbal terpenoids. The current state of theory and practice shows that the class of terpenoids, including sesquiterpene lactones, which are one of the largest groups of secondary plant metabolites, have a wide range of biological activity, and are environmentally harmless to humans and the environment. Cotton seeds of varieties C-6524, C-6532, C-9070, etc. were treated with a preparation of various concentrations (2,0; 1,5; 1,0; 0,5%) and were sown in the field. The following indicators were analyzed: seed germination, plant survival, and the degree of development of characteristics that characterize productivity.
