Vegetative Growth Phase of Mentik Susu Local Rice Species with the Application of Perokan Fertilizer

Abstract

It focuses on examining the impact of Perokan liquid organic fertilizer on the vegetative growth phase of the Mentik Susu rice variety grown in acid-sulfate soil. Mentik Susu is a fragrant Indigenous rice that lacks a strong brand identity but is liked by consumers for its taste and texture. Often, yield constraints are faced because of the type of soil used. The treatments we used are 2mL of NASA fertilizer as a control and four levels of Perokan fertilizer at 1, 3, 5, and 7mL/L water. In the case of the 7mL dose of Perokan, there is a highly significant increase in plant height, which is 88.18±1.6cm, and the number of tillers is 14.75, resulting in the highest yield per plant of 40.10±2.6g. In other words, although the phosphorus, potassium, and organic carbon were detected to be low in Perokan, the quality and slightly acidic pH of its nitrogen were all the ingredients for vegetation growth. From the study, it can be concluded that Perokan fertilizer, especially at the level of 7mL, demonstrates a significant potential in improving the growth and yield potential of Mentik Susu rice under low fertility nutrient soil, providing a reliable and effective organic fertilization alternative.
