Penggunaan Analisis Lintas Untuk Menentukan Peran Faktor Penentu Konsentrasi Herbisida Dalam Tanah

Abstract

The herbicide concentration were determined by bioassay techniques. Tested media were taken from field experiments conducted in PT. Gunung Madu Plantation Lampung from April to November 1991. The experiment consist of 2 treatment factors. First/actors are the rates of dolomite applicatons from 0.00; 0.75; 1.50 and 2.25 ton ha. The second are weed controlled by 6 herbicide rate of application wich are diuron 1.5 kg a.i ha; diuron 3.0 kg a.i.ha-i; ametrin 1.5 kg a.j.ha-i; ametrin 3.0 kg a.i.ha-1, 2,4-D amin 1.5 kg a.i.hlr' and 2,4-D amin 3.0 kg a.i.ha-1. Ohserved parameter are the average values of combined treatment.
