Use of the preparation based on Solanum nigrum as a potato yield stimulator
I. Аnikina, K. Issayeva
Abstract: The use of herbal preparations is an environmentally friendly and biosafety alternative to the use of chemical stimulants to increase the productivity of agricultural plants. The article presents the results of studies of the effect of foliar treatment with the preparation of black nightshade infusion (Solánum nígrum) in concentrations of 0.5% and 0.25% (dry matter) on the productive qualities of potatoes of the Latona variety. The obtained data indicate that the treatment of potatoes with a preparation based on Black nightshade at a concentration of 0.5% increases the average potato yield by 41.5%. At the same time, the number of tubers of the food fraction (size > 55 mm) increases by 47.6%, of the seed fraction (size 35-55 mm) by 35.3%. The use of this treatment is efficient both when growing food and seed potatoes.
