Abstract

The research was aimed to study effect application of sea sand (SS), coconut coir (CC) and banana coir (BC) on the growth and yield of rice (Oryza sativa L.) planted at Ustic Endoaquert soil. The pot experiment was carried out using a factorial design with 3 factors. The first factor was SS consisted of three levels i.e.: 0%, 25%, and 50%. The second and third factors were CC and BC, each consisted of three levels i.e.: 0, 10, and 20 Mg ha-1. Application of SS and BC significantly increased leaf length where the highest increasing percentage was 16.47% which was achieved at 25% SS application. Their effect on leaf numbers and tiller numbers were relatively not similar pattern where leaf number only increased about 65.52% by BC application, while tiller numbers only increased about 10.77% by SS application. Furthermore, the application of CC and BC significantly increased panicle numbers to 29.53% and 29.05%, respectively compared to control. All ameliorants significantly increased panicle numbers, but the best was CC with the increasing up to 46.49% at 20 Mg ha-1 CC compared to SS or BC application. However, only coconut coir significantly increased the rice grain numbers.Keywords: Banana coir, coconut coir, rice plant, sea sand, vertisol [How to Cite: Nurdin. 2014.

Highlights

Heavy metal contamination in the environment is of major concern because the majority of the heavy metals are toxic to the living organisms and the environment, even those considered as essential can be toxic if present in excess (Chirenje et al 2003; Dolan et al 2006; Jarup 2003; Ma and Rao 1997; Silva et al 2005)
Current study revealed that Pb content in roadside soils at the study site was 20.01 mg kg-1
This level was 1.5 times higher than the safe level of Pb in soil (12.75 mg kg-1) as regulated by Balai Penelitian Tanah Indonesia (2002) and it reveals that the roadside soils at the study site are polluted by Pb

Summary

Introduction

Heavy metal contamination in the environment is of major concern because the majority of the heavy metals are toxic to the living organisms and the environment, even those considered as essential can be toxic if present in excess (Chirenje et al 2003; Dolan et al 2006; Jarup 2003; Ma and Rao 1997; Silva et al 2005). Heavy metals may come from many different sources, including vehicle emissions, industrial discharge and other activities (Gibson and Farmer 1986; Harrison et al 1981; Li et al 2001; Thornton 1991; Wu et al 2006). The extensive use of automobile is one of the most important sources of heavy metal contamination in the roadside environment (Garcia and Millán 1994). In the vicinity of roads, dust and the other traffic-related pollutants such as heavy metals, polycyclic aromatic hydrocarbon particles (PAH) and volatile organic compounds
