ABSTRACT

Contribution of red upland rice is highly expected in the future. However, only a few superior varieties of rice are able to adapt well and last long which affects on production. This study aimed to determine effect of several growing media and some local red upland rice varieties on the growth and production and soil C-organic content. This research was conducted from February-June 2017 at Kasa House, Faculty of Agriculture, UISU, North Sumatra, Medan. This study used factorial randomized block design with three replications. The first factor is growing media (M): control (10 kg soil) (M0), 8 kg soil + 1 kg fertilizer + 1 kg cow manure (M1), 6 kg soil + 2 kg hay compost + 2 kg cow manure (M2), and 4 kg soil + 3 kg hay compost + 3 kg cow manure (M3). The second factor is variety (V): Sigambiri (V1), Sikariting (V2), and Pagai Gara (V3). The results showed that The results showed that the best growth and yield of red rice was on the treatment of planting media 3 kg hay compost + 3 kg cow manure + 4 kg soil and Sigambiri varieties. Growing media capable of improving the content of organic C-soil are 3 kg hay compost + 3 kg cow manure + 4 kg soil.
