Action of innovative forms of copper and zink on photosynthetic activity of rice plants under conditions of delta zone of Kuban

Abstract

The influence of various concentrations of innovative zinc-copper micronutrient fertilizer on rice plants as micronutrient, which was invented by a group of scientists from Kuban State Agrarian University named after I.T. Trubilin (patent RU 2546193 “Method for obtaining complex micronutrient fertilizer”) was considered [6]. Under the conditions of field experiments, the effect of foliage spraying of plants with the considered micronutrient fertilizer on the assimilation surface of leaves and the content of photosynthetic pigments was studied. Foliage spraying of rice plants with an innovative composition provided a more intensive accumulation of photosynthetic pigments, as well as an increase in the assimilation surface. Treatment of plants in the tillering phase with a solution of trace elements containing copper and zinc chelates at a dose of 2.0 l/ha creates favorable conditions for the growth and development of rice plants.
