PENGGUNAAN BERBAGAI DOSIS KOMPOS PADA TANAMAN SUKUN (Artocarpus communis) di DAERAH TANGKAPAN AIR DANAU TOBA KECAMATAN HARANGGAOL HORISON KABUPATEN SIMALUNGUN
ABSTRACT: The condition of
critical land in Lake Toba Catchment Area is the cause of the soil unfertility
and impact on crops. Breadfruit plant that can grow in all types of soil and
improving productivity and useful in the greening. Compost is one of the
organic fertilizer which can improve soil structure that can support plant growth.
This study aimed to determine the dosage of compost on seedling growth
breadfruit plant (Artocarpus communis), and improve the ability of growth of
crops in the field. This research was conducted in the Village District of
Haranggaol Horison, Simalungun North Sumatra, from September 2014 to November 2014
by using a non factorial randomized block design with treatment are 0 g, 100 g,
200 g, 300 g, 400 g, 500 g, 600 g, 700 g, 800 g, 900 g, 1000 g with four
replications. The results showed that the addition and using compost did not
significantly affect to the height, diameter, number of leaves, leaf area, and
the vast canopy water content on plant. However, the viability of the plant
reached 97.73% indicated breadfruit plant can grow. Giving compost at a dose of
700 g has given the best growth of the plants of breadfruit plant (Artocarpus
communis). And C / N ratio showed good results in the amount of 12.47; 13.83;
13.68 as equal to the C / N ratio that allowed the plants to absorb soil
nutrients.
