In the conditions of the Rostov region on ordinary chernozems, the effect of micro fertilizers used for foliar feeding when growing lactuca-sativa varieties in open ground under irrigation was studied. The issues of formation of yield and quality indicators depending on the applied micro fertilizers are considered. It was established that the largest yield was obtained when growing the Yeralash variety, the crops of which were additionally treated with Ecofus at a dose of 2 l/ha, and slightly lower values when using Siliplant at a dose of 1 l/ha. The most significant effect in increasing the dry matter content was found with the use of the Nagro preparation for the varieties Eralash, Gascony and Abrek, and early ripening of the products did not contribute to an increase in the dry matter content in the varieties. The use of Siliplant and Nagro effectively increases the content of ascorbic acid in the product, reaching a maximum for the Gascony variety. Additional top dressings do not have a negative impact on the amount of nitrates, and the minimum indicators were noted for the varieties Sorvanec, Abrek and Gascony when treated with Siliplant and Nagro preparations.
