Abstract

The research objectives were to find out the growth responses and the results of providing water treatment and manure from buffaloes to C/N which is different from the rice plant variety. The rice was planted in a pot arranged in a greenhouse. The water treatment consisted of two treatment phases, namely irrigation with interval and continuous irrigation. The provision of manure from buffaloes consisted of without treatment, with treatment of C/N 19, 80:1 and treatment of C/N 10, 15:1. The varieties studied were Inpari 1, Inpari 13, Siramos and Siboru Tambun. The results showed that water treatment had positive influence on the plant development which was significantly seen in the height of plant and the number of plantlet and panicle. The best irrigation was indicated by the irrigation with interval. The provision of manure from buffaloes had influence on the number of plantlet per cluster which was indicated very significantly by 40 HST, significantly by 20HST, and very significantly by 40 and 60 HST; and on the number of panicle per cluster which was indicated significantly by 60 HST and very significantly by 100 HST filled grains, and on the number of empty grains per cluster, indicating positive influence.

Abstract

One of the problems in the paddy field is the lack of availability of nutrient N in paddy soil, it can be overcome by giving azolla and goat manure. The aimis to determine the effect of giving azolla and goat manure for increasing the nutrient N and the growth of rice plants. This research used factorial Random Group Design  (RAK) with two treatment factors and three replications. The first factor is azolla dose (0, 7 tons / ha) and the second factor is goat manure dose (0, 5, 10, 15 tons / ha). This research is implemented in the greenhouse of the Faculty of Agriculture, University of North Sumatra, Medan. The result of the study indicated giving of azolla increased C-organic, N-total, N content, and N uptake of plant. Giving goat manure at a dose of 15 tons/ha increased C-organic, number of tillers, canopy dry weight, root dry weight, N content of N uptake. Providing azolla and goat manure 5 tons/ha the highest increased N uptake of plants and growth of lowland rice plants.   REFERENCES   Abu R.L.A., Z. Basri, U. Made. 2017.
