ABSTRACT

The purpose of this study was the effect of giving Biolite, Humic Acid and NPK and their interaction on the growth of rice plants. This research was conducted in Tegal Sari , Dolok Masihul District , Serdang Bedagai Regency with a height of ± 40 meters in above sea level . Alluvial soil type with flat topography. This research was carried out in March 2022 to July 2022. This study was arranged based on a factorial Randomized Block Design (RBD) with 3 treatment factors and 3 replications. The treatment factors were the provision of NPK fertilizer, namely 3 levels and the provision of Humic Acid, namely 3 levels and Biolitee, namely 3 levels. Each treatment was repeated 3 times so that there were 3x3x3x3 = 81 experimental units. The results of the analysis showed that the application of NPK fertilizer had a significant effect on the parameters of paddy rice plant height. The administration of Humic Acid and Biolite had no significant effect on the growth of rice plants. The combination of various doses of NPK, Humic Acid and Biolite did not significantly increase the growth of rice plants. Provision of NPK fertilizer with recommended dose of 250 kg/ha and administration of Humic Acid : 3 kg and 20 kg Biolite are the best doses for growing rice plants.
