Efficiency of use of microelements in cultivation of sweet pepper during irrigation in the subzone of light chestnut soils of the Volgograd region

Abstract

The results of studies of scientifically grounded use of microelements in sweet pepper crops, as an important factor in increasing the yield of vegetable crops and improving the quality of products, are presented. The purpose of our research was to substantiate the influence of the use of trace elements in the technology of sweet pepper cultivation on the growth and development of plants, the productivity and quality of the products of this culture. The experimental part of the work was carried out in 2014-2019 in the subzone of light chestnut soils of the Volgograd region. Experiments on the study of trace elements were carried out by pre-sowing seed treatment and foliar feeding of plants. Chemically pure compounds of manganese sulfate, zinc sulfate, copper sulfate, ammonium molybdate, boric acid were used as microelements. The use of trace elements in the dry-steppe zone of the Lower Volga region is an important agricultural technique that helps to accelerate growth, development, increase productivity and improve the quality of pepper fruits. It is recommended to carry out pre-sowing treatment of seeds with solutions of boric acid (0.29 g / 1 l of water), copper sulfate (0.20 g / 1 l of water) and manganese sulfate (0.16 g / 1 l of water) (the ratio of the weight of seeds to the solution 1: 2) as a way to increase seed vitality, speed up yield and improve seedling quality. In order to increase the yield and improve the quality during the budding period of peppers, it is necessary to carry out foliar dressing, first of all, with solutions of boric acid (0.29 g / 1 l of water), ammonium molybdenum (0.10 g / 1 l of water), water consumption 1 l / 10 m2. Due to its high efficiency, simplicity and availability, pre-sowing seed treatment and foliar feeding of plants with microelements will find wide application in vegetable growing.
