Weed Management Practices on Maize Grown on Field With One Season of Residue of Manure and Green Organic Composts
Year: 2016
Type: book-chapter
Abstract: The research was aimed to study effectiveness of weed management practices using herbicide mixture of atrazine \nand mesotrione and hand weeding on maize grown in field with one season of organic compost residues. The \nresearch was conducted in Bengkulu, Indonesia, from November 2014 until February 2015. Research was \narranged in split plot design. Residue of organic compost was a main plot which consists of residue of manure \ncompost, residue of empty fruit bunches (EFB) of oil palm compost, and non-residual field. Weed management \npractices 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 \nheight, leaf area, yield, dry weight of 100 grains, and total weed biomass. The best weed management practice \non maize field with organic compost residues is the use of herbicide mixtures applied preemergence, which \nincreased maize yield by 52 percent. Interaction of the trials also suppressed weeds significantly, which was \nobserved in the reduction of total weed biomass, where the strongest suppression was observed on postemergence \ntrials of herbicide mixture of atrazine and mesotrione in the non-residual plot.
