Effect of diatomite, potassium silicate and silica-nanoparticles on chlorophyll a content (mg g–1 FW) of Brunfelsia grandiflora in 2022 and 2023 seasons. DM2.5, DM5 and DM10 are application 2.5, 5 and 10% of diatomite, respectively; PS1, PS2 and PS3 are application of potassium silicate at a rate of 1, 2 and 3 g L–1, respectively; SNP100, SNP200 and SNP300 are application of silica-nanoparticles at a rate of 100, 200, and 300 mg L− 1, respectively; CK is check treatment. Values are means of 3 replicates ± SE; the same alphabets means that statistically non-significant by Duncan’s new multiple range test at p < 0.05.
