Effect of silicon dioxide nano fertilizer on the growth and yield marigold (tagetes erecta. L)

Abstract

An experiment to study the “Effect of silicon dioxide nanofertilizer on the growth and yield of marigold (Tagetes erecta L.)” was laid out in Completely Randomized Design (CRD) with three replications. The experiment involved different concentrations of Silicon dioxide nano fertilizer, which was applied by foliar and soil application method. There were twelve treatments, viz., from T₁ to T₁₂. Among them, T₁ is control, T₂ and T₃ are only foliar applications, T₄,T₅,T₆ is only soil application, and T₇ to T₁₂ are both foliar and soil application. The treatment T₇ (Foliar application - 100 ppm, soil application - 200 ppm) recorded maximum values for all the growth, flower and yield parameters followed by T₈ (Foliar application - 100 ppm, Soil application - 400 ppm). From the present study, it is recommended that application of silicon dioxide nano fertilizer (SiO₂) as foliar spray at 100 ppm and soil application at 200 ppm improved growth and yield of marigold.
