The effect of foliar application of nano and micro particles of sodium silicate on concentration and uptake efficiency of nutrition in the shoot

of potato

Abstract:

Positive effects of silicate compounds foliar application on growth and absorption of essential elements in poaceae family has been proven, but research on other plants about effects of nano particle received less attention. So this research designed to evaluate effect of sodium silicate particle size on potato shoot in form of randomized complete

block design and factorial arrangement in 3192 in research greenhouse of Agriculture

Faculty of Ferdowsi University of Mashhad. Treatments included two particle size

(nano and micro) and concentrations (control, 911, 311, 211 and 411 mg l

-9

). Results

showed positive and significant effect of sodium silicate application on concentration of

sodium, potassium, calcium, magnesium, phosphorus and silicon, and in highest level of

concentration, mentioned character in nano particle were 31, 31, 90, 21, 91 and 91

percentage higher in comparison with the micro particles, respectively. With increase of

sodium silicate concentration, nitrogen concentration in leaf increased significantly.

Absorption efficiency of sodium and silicon in potato shoot was significantly higher in

nano than micro. In each of concentrations level, absorption efficiency of potassium,

calcium, magnesium, phosphorous and nitrogen were higher with nano particles,

significantly. Overall, effects of nano particle of sodium silicate on concentration and

9

absorption efficiency of mentioned element, were more in comparison with micro

particle and concentration of 411 mg l

-9

had greatest effect.
