ABSTRACT
The experiment about "The Effect of Dosage of chlor Per Planting Herbicide on Weeds and Yield (Zea mays L.)" had been conducted at Tunggulrejo, of Ala- Maize Grabag, Purworejo, on latosol soil type, pH 6-5 and an altitude of 16 m above sea level. The experiment was started on 13th October 1989 until 12th Januari 1990.
The method of this experiment was Randomized Com- pletely Block Design (RCBD) with seven treatments and four tmes were 1 replication. The seven treatment of the experiment were :
Ag without herbicide (control)
A herbicide dosage 1.5 1/ha
Ag herbicide dosage 2.0 1/ha
A herbicide dosage 2.5 1/ha
A herbicide dosage 3.0 1/ha
As herbicide dosage 3-5 1/ha
A herbicide dosage 4.0 1/ha
The result of the experiment showed, that the of treat- dosage of alchlor pre planting herbicide highly ment significant influenced to the fresh weight of 도하다 per plot, dry weight of weeds per plot, fresh weight of ear. weight of 1000 seeds, and significant influenced to the dry weight of ear, dry weight of seeds per plat, but did influence to sample plant. the not length of ear and number of ears per

The heghest yield reached by treatment of 2.5 1/ha was 5.53 kg dry weight of seeds per plot ог 8147 that kg/ha.
