LSD, least significant difference (
P
< 0.05).
∞
Values with the same letter are not significantly different between nanoparticles, i.e., within the rows (
P
< 0.05).
Data were pooled among the three crops. All data presented were the mean of three plants cultivated in soil from three different plots and from three
consecutive experiments conducted under greenhouse conditions, and were sampled 20 days after sowing.
