Foliar application of titanium on potato crop

Although titanium (Ti) is not considered a nutrient, researches demonstrate that Ti leaf application can provide beneficial effects on plants growth. The objective of this study was to evaluate the influence foliar applications levels metabolism, nutrient uptake and yield potato crop, Agate cultivar. experiment conducted in randomized complete block design with five treatments four replications. were composed 0, 10.2, 15.3, 20.4 22.9 g ha-1, divided into three during growth stage, tuberization stage tuber filling stage. Foliar increase chlorophyll content (Spad value) do interfere N, Zn Cu accumulation. Increasing linearly reduce Mn, lipid peroxidation (PL) urease activity peroxidase (POD), nitrate reductase (ANR), catalase (CAT), proline Fe maximum level around 3 6 ha-1. In at high Ti, there an CAT while ANR has its lowest value. are related Fe, superoxide dismutase (SOD) low PL activity. ideal applied by for greater tubers 11.3
