“…Experiments have demonstrated that Ti chelates are able to promote the development of young plants and can increase the activity of some enzymes (Botia et al, 2002). Further, Ti has been found in the mineral composition of all groups of plants (El-Ghonemy et al, 1977;Guha and Mitchell, 1965), fungi (Silverman and Muñoz, 1971) and lichen (Takala and Olkkonen, 1985) with the largest concentrations in aquatic organisms (Dumon and Ernst, 1988).…”

Several studies have been carried out on the application of titanium in plant nutrition in recent decades. They indicate that this element has a positive effect on crop phenological events such as germination, root formation, vegetative growth, maturation, as well as resistance to biotic or abiotic stress conditions and general crop health status. Titanium has also been reported to boost the uptake of macro and micronutrients, enzymatic activity in plants, and consequently increase yield. Therefore, pioneering studies of foliar applications of titanium in potato crops are being carried out in Brazil. They demonstrate that titanium reduces urease enzyme activity, but increases peroxidase and nitrate reductase activity during potato growth. During tuberization, there is a positive correlation between superoxide dismutase & peroxidase enzyme activity and titanium application. Although the results are promising, more data is needed regarding the effects of this element on crop performance. This review describes the characteristics of this element and reports innovations regarding its use in plant nutrition.

“…The bulk of TiO 2 is extracted from the mineral ilmenite (FeTiO 3 ), which is found in metamorphic and igneous rocks (Skocaj et al, 2011), and which considering the optimum pH range for most crops of 4.0-8.0 is insoluble, thus unavailable to plants and also without possible toxic effects (Dumon and Ernst, 1988).…”

“…Although in this form it is not bioassimilable, when applied in a watersoluble, pHstable Ti-chelate organic acids form such as ascorbate, citrate or malate, it has a beneficial effect on various physiological processes, i.e. it stimulates the chlorophyll biosynthesis and the activity of many enzymes (catalase, peroxidase, lipoxygenase and nitrogen reductase) and the uptake of some nutrients for plants, as well as accelerates plant growth, increases crop yield and improves the crop quality (Dumon and Ernst, 1988;Pais et al, 1991;Carvajal and Alcaraz, 1998;Hrubý et al, 2002;Du et al, 2010). Titanium applied via roots or leaves stimulates plant growth in a species-specific manner.…”

“…Titanium applied via roots or leaves stimulates plant growth in a species-specific manner. The effect of titanium depends on the plant species, plant age and the tissue concentration of other minerals (Dumon and Ernst, 1988). The effect of foliar titanium application was substantially influenced by the nutrient nitrogen status of the plants.…”

The growing period for early potatoes is extremely short, only 50-80 days from planting to harvest. To obtain a high marketable tuber yield in such a short period good conditions for plant growth must be ensured. In modern agriculture, plant growth stimulants have been gaining increasing importance. Although titanium (Ti) is neither a major nor minor nutrient for plants, it is classified as a beneficial element for plant growth. This paper analyses the effect of dose (0.2 dm ) on the yield and yield components of very early-maturing potato cultivars ('Lord' and 'Miłek'). Potatoes were harvested 75 days after planting (the end of June). Tytanit ® caused an increase in the tuber number and tuber weight per plant, particularly under stress conditions, although the effect of cultivars was not consistent. The growth stimulant did not have any effect on the average tuber weight. Following the application of Tytanit ® , the total tuber yield was higher, on average, by 2.26 t*ha -1 (7.5%), and the marketable tuber yield (diameter above 30 mm) by 1.88 t*ha -1 (6.4%). The tuber number per plant was higher when Tytanit ® was applied at the dose of 0.2 dm 3 *ha -1 . Potato plants produced greatest tubers when Tytanit ® was only applied in the leaf development stage (BBCH 1416). With double Tytanit ® applications, i.e. in the leaf development stage and with repeated treatment in the tuber formation stage, both the tuber number and tuber weight per plant were lower. The Tytanit ® application contributed to improved marketable value of the early potato yield due to a decreased share of small tubers (diameter below 40 mm) and an increased share of large tubers (diameter above 51 mm) especially in a year with a periodical water shortage in the tuber growth period. The examined very earlymaturing potato cultivars showed a differential response to Tytanit ® . The growth stimulant had a greater effect on the tuber number and tuber weight per plant for the 'Lord' cultivar. Following the Tytanit ® application, the total tuber yield of 'Lord' cultivar was higher , on average by 3.71 t*ha -1 (12.7%) and marketable tuber yield by 3.22 t*ha -1 (11.4%). Tytanit ® caused an increase in tuber yield of 'Miłek' cultivar only in year with the highest air temperature and water shortage in June -the total tuber 441

“…Beneficial effects are often exploited by adding titanium to various complex micronutrient fertilizers. Many investigators (Dumon and Ernst, 1988) demonstrated the promotion of growth by titanium, whether applied as a fertilizer to the soil, or as a spray to the leaves. Pais (1983) carried out numerous field experiments and found that titanium-chelate-treated apple trees yielded the fruits with higher soluble solids, sugar and acid content.…”

Titanium (Ti) is a very interesting chemical element, especially physiologically. Although Ti is not toxic for animals and humans, its effects on plants show remarkable concentration dependence. Whereas for plants, it shows beneficial effects on various physiological parameters at low doses. This study was conducted to evaluate the effect of bulk and nanoparticles titanium foliar application on some agronomic traits, seed gluten and starch contents of wheat under water deficit stress conditions during 2010-2011 growing seasons. The experimental design was randomized in complete blocks arranged in split-split plots with four replications. The factors included normal irrigation, water deficit stress (irrigation withholding at two growing stages of stem elongation and flowering), two growing stages for water deficit stress induction and titanium applications, five titanium concentrations, sources including control of titanium oxide (bulk), and three concentrations of 0.01%, 0.02%, and 0.03% of titanium dioxide nanoparticles. Plant height, ear weight, ear number, seed number, 1000-seed weight, final yield, biomass, harvest index, gluten, and starch contents were assayed. The results showed that water deficit stress caused significant decrease in plant growth, yield and yield components. In addition, among the different titanium treatments, titanium dioxide nanoparticles at 0.02% increased almost all agronomic traits including gluten and starch content. Thus, the application of titanium dioxide nanoparticles under conditions of water deficit stress is recommended.
