Experimental evaluation of the protective properties of a humic preparation in relation to cultivated plants under salt stress

Abstract

In connection with the widespread problem of soil salinity, the issue of increasing the salt tolerance of cultivated plants is becoming increasingly important. In this aspect, humic substances and preparations based on them are very promising. The aim of the study was to evaluate the effect of humic preparations on agricultural crops and lawn cereals under salt stress. Under laboratory conditions, the protective properties of the humic preparation «Ekorost» were evaluated in relation to the industrial crop Brassica rapa L. and to lawn grasses under the influence of salt stress induced by excessive concentrations of sodium chloride and anti-icing agent. It was revealed that the humic preparation «Ekorost» exhibits protective properties in relation to the indicated test cultures under conditions of artificially simulated salt stress, which is expressed in a noticeable stimulation of their germination and growth processes. In all the experiments, the most effective was a 0.1% aqueous solution of the drug «Ekorost», which allows us to recommend it in the indicated dosage to increase the salt tolerance of oil radish ( Brassica rapa L.) and lawn cereals.
