ABSTRACT

Upland rice cultivation in dry land is often constrained by the lack of availability of P nutrients due to low soil pH, especially when planted on Andosols. CMA is beneficial for plants because CMA is very useful for increasing nutrient uptake, especially P elements. The research was carried out at the gauze house of the Faculty of Agriculture, Universitas Islam Sumatera Utara, Gedung Johor, Medan, North Sumatra with an altitude of ± 25 m above sea level. The study used a completely randomized block design with three replications and a dose of CMA as a treatment. The results showed that the administration of CMA at a dose of 45 g/polybag was able to increase the growth and production of upland rice plants.
