Respon Pertumbuhan Sorghum (Sorghum bicolor (L.)) Varietas Kawali Pada Tanah Bekas Pertambangan Emas Rakyat

Abstract

Sorghum (Sorghum bicolor (L.)) is a cereal food plantswhich can be utilized as heavy metal hyperacumulating plant. The research aims to find out the response of the growth of sorghum that cultivated on post gold mining soil (tailing). This research was conducted for 3 months from November 2016 to January 2017. It was done in the Greenhouse and Biology of Biology Departement in MIPA Faculity Universitas Tanjungpura Pontianak. Soil analysis was done in PT. Sucofindo Pontianak. This research used Completely Randomized Design (RAL) with five variations of soil sampling distance, namely P1 = 0 m, P2 = 75 m, P3 = 150 m, P4 = 225 m, P5 = 300 m. Each treatment was repeated three times, so there were 15 experimental units. The results show that sorghum can grow on soil sampling at distance 0- 300 m, but the best growth is at distance of 300 m. The further the distance from the tailing center, the vhiger the number of its leaves, height, wet weight, and dry weight.
