Application of Inorganic Fertilizer With NanoChisil and Nanosilica on Black Corn Plant Growth (Zea Mays L.)

Corn is one of the most important sources of carbohydrate and protein in Indonesia, while black corn has not been widely known. One way to increase the growth of black corn plants is to optimize the use of fertilizer, i.e. by a combination of NPK fertilizer with NanoChisil or Nanosilica fertilizer. NanoChisil is a fertilizer with chitosan and silica, while nanosil fertilizer is a fertilizer with silica content. Both of these fertilizers are nano-sized. NPK is a fertilizer with nutrient contents of Nitrogen, Phospor and Potassium. This study aims to determine the combination effect of NPK fertilizer with NanoChisil or Nanosilica on the growth of black corn plants. This research used Completely Randomized Design (CRD). The treatments used were P0 control (without fertilization); P1 (25% NanoChisil 75% NPK combination); P2 (25% Nanosilica 75% NPK combination); P3 (100% NanoChisil); P4 (100% Nanosilica). The study consisted of 5 treatments with 5 repititions. The research parameters consist of plant height, number of leaves, wet weight, dry weight, and the stomata amount. The data analysis used is Analysis of Variance (ANOVA) if the difference is evident, the analysis is continued by Duncan Multiple Range Test (DMRT) at 95% significant level. The results showed the use of NPK fertilizer combination with NanoChisil and NPK fertilizer with Nanosilica have an effect to increase plant height, number of leaves, wet weight, and dry weight. The allocation of 25% NanoChisil 75% NPK is most optimal in increasing plant height, number of leaves, wet weight, and dry weight.
