The role of silicon and salt stress in some vegetative traits and mineral content of mint plant Mentha piperita L.

The experiment was carried out during agricultural season 2021, to study the effect of adding two types silicon on vegetative growth characteristics and mineral content mint plant grown under salt stress. designed using Randomized Complete Block Design RCBD as a factorial with factors three replicates, each replicate contains 9 experimental units, unit consists 3 pots. first factor included oxide well comparison (S0 control, S1 nano-silicon, S2 normal silicon); second is stress pure NaCl in concentrations, (N0 0 g L-1, N1 0.45 L-1and N2 1.45 L-1). results showed that there are significant differences caused by number lateral branches, leaves, total leaf area, treatment S2N2 outperformed significantly highest value branches number, leaves area which were 8.60 plant-1, 286.80 1211.5 cm2 plant-1 respectively compared control S0N0 gave lowest values; 7.10 182.90 643.3 for same traits. S2N0 superior NPK percentages N 3.30%, P 0.5550%, K 1.96% S0N2 2.90%, 0.4283%, 1.81%.
