The effect of microfertilizers on the morphometric parameters of plants and the duration of the growing season of lettuce varieties (Latuca sativa L.)

Abstract

In the conditions of the Rostov region on ordinary chernozems, the effect of foliar top dressing with microfertilizers on the formation of the vegetative part and the timing of harvesting varieties of lettuce (Latuca sativa L.) in open ground under irrigation was studied. The issues of forming indicators of the average weight of 1 plant, as well as the height associated with it, depending on the applied microfertilizers, are considered. A general positive trend has been established to accelerate maturation, increase the average weight and height of plants when using foliar top dressings with an ambiguous varietal response to them. Ecofus, Siliplant and Nagro, containing silicon compounds, increase the average weight by more than 140% and the height of plants by 5.5-5.7 cm in comparison with the control. The maximum indicators were noted for the varieties Abrek and Eralash
