Effect
Tytanit treated Tomato, cv. ISI 68249, showed no significant difference in total yield (kg m-2) but significantly reduced marketable yield (kg m-2) (-12.3%), compared to untreated control plants, at biostimulant application rates of 80 or 240 Ti ha-1. Biostimulant application rate of 480 Ti ha-1 resulted in no significant change in total or marketable yield whilst the 960 Ti ha-1 application rate resulted in significantly increased total yield (+17%) and significantly increased marketable yield (+14%), compared to untreated control plants. Tytanit application resulted in significantly higher nitrogen (N) (+15.7%; not significant at dose of 480), higher phosphorous (P) (+3.9%; significantly lower at dose of 80; significantly higher at dose of 480-960), lower potassium (K) (-4.2%; significantly higher at dose of 80), higher calcium (Ca) (+5.3%; significantly lower at 80) and higher magnesium (Mg) (-9.3%; significantly lower at dose of 80) content in leaves and significantly higher N (+12.7%; no difference at dose of 240), no difference in phosphorous (P) (7.5%), no difference in potassium (K) (+2.6%), lower Ca (-24%; significant at dose of 80), higher Mg (+8.3%; no difference at dose of 240-480), no difference in dry mass percentage (-1.8%), higher vitamine C content (+14.3%, not significant at dose of 240), no difference in total sugar content (-0.4%) and no difference in actual acidity (-0.2%), averaged across different application doses, compared to the untreated control plants.
