Abstract

The research was aimed to study effectiveness of weed management practices using herbicide mixture of atrazine and mesotrione and hand weeding on maize grown in field with one season of organic compost residues. The research was conducted in Bengkulu, Indonesia, from November 2014 until February 2015. Research was arranged in split plot design. Residue of organic compost was a main plot which consists of residue of manure compost, residue of empty fruit bunches (EFB) of oil palm compost, and non-residual field. Weed management practices was a sub-plot which consists of pre- and post-emergence application of herbicide mixtures at 1.0 kg a.i. ha-1, hand weeding, and untreated plot. Twelve treatment combinations were replicated three times. Results showed significant interactions between weed management practices and residue of organic compost on plant height, leaf area, yield, dry weight of 100 grains, and total weed biomass. The best weed management practice on maize field with organic compost residues is the use of herbicide mixtures applied preemergence, which increased maize yield by 52 percent. Interaction of the trials also suppressed weeds significantly, which was observed in the reduction of total weed biomass, where the strongest suppression was observed on postemergence trials of herbicide mixture of atrazine and mesotrione in the non-residual plot.
