“…In sustainable crop production, the application of silicon has been increasing as a low input and environmentally friendly technique to stimulate plant growth and alleviate abiotic stresses [Kaur et al 2021, Malik et al 2021, Wang et al 2021]. Althought potato is a silicon low-accumulator, foliar silicon application may contribute to enhancing potato yield [Luz et al 2008, Soratto et al 2012, Vulavala et al 2016, Laane 2017, which was confirmed in the present study.…”

This paper analyses the effect of dosage (0.25 dm3 ha–1 or 0.50 dm3 ha–1) and time (the leaf development stage – BBCH 14–16, tuber initiation stage – BBCH 40–41, at both the leaf development stage and tuber initiation stage) of silicon-based stimulant Optysil application (200 g SiO2 and 24 g Fe in 1 dm3) on early potato yield and yield components. Optysil resulted in an increase in tuber number and tuber weight per plant. As a result, under periodic water deficits during tuber bulking, Optysil increased marketable tuber (with a diameter above 30 mm) yield by an average of 6.90 t ha–1 (50%) and under drought conditions during the potato growth period by 0.70 t ha–1 (8.6%). Under periodic water deficits during tuber bulking, the marketable tuber number per plant and marketable yield were greatest after applying 0.50 dm3 ha–1 of Optysil in the tuber initiation stage (BBCH 40–41). Under drought conditions, the most practical were two Optysil applications at 0.25 dm3 ha–1. The Optysil application improved the market value of the early potato yield by increasing the share of medium-sized tubers (with a diameter of 41–50 mm).

“…The beneficial effects of silicon are particularly distinct under environmental-stress conditions [3,5,6]. Since silicon plays an essential role in mitigating biotic and abiotic stresses (high temperature, freezing, drought, salt stress, disease and insect stress, and other stress factors) on plants [4,5,[7][8][9][10], the use of silicon as a biostimulant to improve plant growth under stress conditions and increase crop productivity has been increasing.…”

As silicon induces abiotic stress tolerance in crop plants, it was hypothesized that foliar silicon application could improve potato growth in an early crop culture. The effect of dosage (0.25 dm3·ha−1 or 0.50 dm3·ha−1) and time (the leaf development stage, BBCH 14–16, tuber initiation stage, BBCH 40–41, or both the leaf development stage and tuber initiation stage) of application of the silicon-based biostimulant Optysil (200 g SiO2 and 24 g Fe in 1 dm3) on potato growth was investigated. Optysil caused an increase in plant height and above-ground plant biomass, enlarged leaf area and decreased leaf weight ratio (LWR), and, as a result, increased tuber number and tuber weight per plant. The effect of Optysil depended on a water deficit during potato growth. The average tuber weight per plant in the cultivation treated with Optysil was higher by 23% under periodic water deficits during potato growth, and by 13% under drought conditions, than in the cultivation without the biostimulant. Dosage of Optysil had a significant effect on above-ground plant biomass and leaf area in the warm and arid growing season. Under drought stress, Optysil at 0.50 dm3·ha−1 stimulated potato growth more than at 0.25 dm3·ha−1. Under periodic water deficits during potato growth, the time of Optysil application affected potato growth more than the biostimulant dosage. The plants produced greater above-ground biomass and had a larger leaf area with two Optysil applications; one in the initial plant growth period (BBCH 14–16), and a repeated treatment in the tuber initiation stage (BBCH 40–41). The tuber weight per plant was positively correlated with the plant height, above-ground plant biomass, leaf area, and LWR.
