The Respone of Magrove Rhizophora Apiculuta Growth to Mud Stress Sidoarjo

Abstract

This study aims to know the influence of the growing media Sidoarjo mud on the response of plants Rhizophora apiculuta on growth. This research was conducted in greenhouse of Faculty of Agriculture, University of Muhammadiyah Sidoarjo in April-June 2016.

The results showed differences in the concentration of the Sidoarjo mud negative effect on all variables observation. Sidoarjo mud concentration of 40% and 50% obtain a low response. While the concentration of 10% content of Sidoarjo mud showed a response not unlike the growth without Sidoarjo mud.
