ABSTRACT

Rice is the main food for almost all people in Indonesia, whose population is increasing. However, the increase in population was not followed by an increase in the area of paddy fields for rice cultivation, which is a producer of rice. Upland rice is one of the solutions to increase rice production because it can be grown on dry land even on marginal land but it must be done with the right cultivation techniques, including by applying vermicompost organic fertilizer. This study aims to determine the effect of vermicompost in increasing the growth and yield of upland rice on marginal land, especially ultisols. The study was conducted in the screen house of the UISU Faculty of Agriculture experimental field using a Non-Factoral Randomized Block Design of three replications with a dose of vermicompost as a treatment. The results showed that the dose of vermicompost significantly affected the growth and yield of upland rice. Plant height, flowering age and panicle length of upland rice showed a linear response with increasing doses of vermicompost given, while the number of productive tillers and milled dry weight of upland rice showed a quadratic response with various doses of vermicompost. The optimum dosage of vermicompost to increase the number of productive tillers and milled dry weight of upland rice to a maximum limit were 34.71 t/ha and 62.04 t/ha, respectively.
