Effect of Tytanit on the dry matter and macroelement contents in potato tuber

This paper analyses the effect of the dose (0.2 L*ha-1 or 0.4 L*ha-1) and date (a single application at the leaf development stage – BBCH 14-16 or at the tuber formation stage – BBCH 41-43, and a double application at the BBCH 14-16 and BBCH 41-43 stages) of the application of Tytanit® (8.5 g Ti per liter in the form of Ti-ascorbate) on the dry matter and macroelement contents in tuber of very early potato cultivars (‘Lord’ and ‘Miłek’). Potatoes were harvested 75 days after planting (the end of June). Tytanit® did not affect the content of dry matter and nitrogen, phosphorus, potassium, calcium, magnesium or sulphur in potato tubers. Following Tytanit® application, there was only an increase in sodium content. The sodium content in the immature potato tubers was higher after the application of 0.2 L*ha-1 of the Tytanit®. Regardless of the Tytanit® dose, the sodium content in tubers was the lowest when the growth stimulant was applied only once in the leaf development stage (BBCH 14-16), particularly under the more favorable thermal and moisture conditions for early crop potato culture. Following Tytanit® application, the weight ratios of Ca:P, K:Ca and K:Mg in potato tuber were similar, and the weight ratios of N:S, Na:Ca and Na:Mg were broader compared to the cultivation without the growth stimulant, although the ratio of the sum of univalent cations to the sum of bivalent cations (K+Na):(Ca+Mg) was at the same level, both in the cultivation with and without Tytanit®.
