The influence of granting npk fertilizer and nanosilic fertilizers on the growth of Ganyong plant (Canna edulis Ker.)

Abstract

Ganyong is a herbaceous plant which included in the tuberous plant group. One of the ways to increase the growth of ganyong plants is by combining Nanosilica and NPK. Nanosilica is an fertilizer with nutrient contain nano size of silica. This research was conducted using Completely Randomized Design (CRD) and consisted of 6 treatments with 3 replication were control (without nanosil and NPK fertilizers); (combination 0% nanosilic and 100% NPK); (combination 25% nanosilic and 75% NPK); (50% nanosilic and 50% NPK); (75% nanosilic and 25% NPK) and (100% nanosilic and 0% NPK). Parameters of this research consisted stomata and growth rate: plant height, leaf quantity, leaf color, wet weight and dry weight. Analysis of Variance (Anova) were used to analyze the data, and if significant difference were found, the data tested further by Duncan Multiple Range Test (DMRT) at 95% significant level. The results showed that the combination of Nanosilica and NPK fertilizers affected plant height, dry weight and wet weight of the plant. The combination of 75% nanosil fertilizer and 25% optimal NPK fertilizer increased plant height, dry weight and wet weight on ganyong. The combination of nanosilic and NPK did not affected to amount stomata in ganyong.
