A Novel Approach to Evaluate the Interaction Effects of Nano Silica Bokashi Fertilizer on Several Rice Varieties Using Multivariate Analysis

Abstract

The assembly of superior rice varieties requires growth environmental engineering as a motor in optimizing its production.One uses a specific type of fertilizer known as nano silica bokashi.This technology involves the application of nano-sized silica particles, which are encapsulated in a bokashi carrier, to the soil.Evaluating the interaction between this nano silica bokashi fertilizer and several high-yielding varieties is necessary.However, the effectiveness of these technologies must be systematically assessed, so the application of multivariate and index analysis concepts can be a solution in considering fertilizer technology.This study, conducted at the greenhouse of the agricultural faculty at Hasanuddin University from September to December 2023, by using a split-plot design.The main plot factor consisted of nano silica bokashi dosage (four dosages), the subplot being varieties (seven varieties), and three replications, resulting in 96 experimental units.Based on this study, evaluation indices based on flowering age, percentage of filling grain, and yield can give an idea of the potential for responsibility and adaptability in parallel.Notably, early maturing rice varieties, namely Cakrabuana, Padjajaran, and M70D, have shown promising results with adaptive evaluation index (positive index values) and a determination above 0.5.With their potential for early maturation and high yield, these varieties are recommended as effective options for developing nano silica bokashi fertilizer.The optimal dose of the fertilizer ranged from 400-600kg.ha - .
