Response of vegetative phase growth of very early maturing rice plant to the application of liquid biosilica in paddy field

Abstract An increase in the cropping index causes land to be cultivated more intensively and has impact on decreasing Silica content (Si) so that it is necessary add Si support growth of rice plants, especially intensive land. This research aims study effect biosilica vegetative phase several very early maturing varieties. The was conducted from September December 2022 Gorontalo using a Split Plot Design. variety as main plot dose liquid subplot. results showed treatment Inpari 19 with 4.5 L ha −1 had highest number stomata density. Individually, Cakrabuana plant height, tillers smallest flag leaf angle. Meanwhile, at height In addition, 13 varieties 3.0 gave best development blast disease intensity.
