Microelements application methods influence on physiological-biochemical processes and yellow pepper yields

Abstract

Abstract According to the results of numerous researches carried out in the Russian Federation and abroad, it was found that microelements, at their skillful use, are an important factor in increasing crop yields and improving the quality of products. The aim of our research was to study the pepper plants pre-sowing seed treatment and foliar feeding with microelements influence on the growth, development and productivity of this crop. The experimental part of the work was carried out in the period of 2014 … 2016 in the conditions of the Volgograd region. Experiments on the study of microelements were carried out according to a scheme consisting of 3 options: application into soil; presowing seed treatment; foliar top dressing of plants. Chemically pure compounds of manganese sulphate, zinc sulphate, copper sulphate, ammonium molybdate, and boric acid were used as microelements. The use of microelements in the conditions of the dry steppe zone of the Nizhneje Pvolzhje region is an important agrotechnical method, contributing to the acceleration of growth, development, increase in yield and improve the quality of the pepper fruits. It is recommended to carry out pre-sowing seed treatment by 0.05% solutions of copper sulphate, boric acid and manganese sulphate, as a way to increase seed viability, accelerate yield and improve seedling quality. In order to increase the yield and improve the quality during the period of pepper budding, foliar top dressing should be carried out by 0.05% solutions of boric acid, ammonium molybdate. Due to its high efficiency, simplicity and availability, presowing seed treatment and foliar top dressing of plants by micro-elements will find wide application in vegetable production.
