An Assessment of the Influence of Foliar Spray Gradient Concentrations of TiO2 on Maize

Abstract

A lysimeter experiment was conducted in 2019 to investigate the impacts of foliar spraying of titanium oxide (TiO2) on maize plant development, yield, and chemical characteristics. The effect of three concentrations of Ti (2, 4, and 8 ppm Ti) and nil as a control on the characteristics of maize in sandy soil was investigated using three replications in a complete randomized design. The growth of maize
plants, yield and yield components, quality metrics, and nutrient uptakes like N, P, and K (%) have all been examined. As a result of foliar spraying 8 ppm Ti in the application (N-P-K + Ti 8 ppm) onto leaves of maize plants, a significant enhancement was seen in the final plant length (11.7 %), chlorophyll (9.4%), W.100 grain (17.4%), fresh and dry weight of kernels plant-1 (7.5 and 21.3 %) and kernels and grains yield pronouncedly increased (4714.0- and 3469.2-ton fed-1) with an improvement (10.2 and 14 %) correspondingly, whenever compared its control (N-P-K) without Ti. Consistent with the findings, titanium is a helpful mineral for plants at low  concentrations.
