Abstract
Research was conducted on green house of Post Graduated (Magister and Doctoral Program) of Sriwijaya University, during October until December 2009. Completely Randomized Design was adopted on this research with 8 treatments and four replication. Treatments are rate concentration (dosage) of Alacchlor herbicide on quartz sand media. Duch as : H1=0 ; H2=0.003 ; H3=0.03 ; H4=0.3 ; H5=3 ; H6=30 ; H7=300 and H83000 ppm. The result showed that of Alachlor herbicide treatment have not gave significant effects on percentage germinating of sweet corn, while on germinating of bulbs nut-sedge gave some variante effects regarding to rate dosages. So far applications Alachlor on rate dosage 3000 ppm (equal 2,6 kg ha-1) have shown crops phytotoxicity by reduce length of roots of sweet corn 53,30% and reduced shoots growth 60,03%. The length of roots and shoots of seedling nut-sedge reduce regarding to the increased rate of alachlor. Application alachlor on rate 3 ppm induce reduction of roots nut sedge 80,77% and shoots elogatoin reduce 54,62%. Retarding growth of nut sedge achieved 100% with the application of alachlor on rate 3000 ppm. The application alachlor on 3000 ppm gave the effects on reduced dry weight of roots and shoots of seedling sweet corn as much as 57,88% and 61,69%. The other side growth retarded by alachlor against nut sedge had appear on rate dosage 3 ppm by reducing dry weight of roots amounting to 86,37% and shoots of seedling nut sedge amounting to 76,77%. Based on these research result can be conclude Alachlor was selective herbicides for sweet corn and effective to control growth of nut-sedge.
