Abstract

Imperata cylindrica contains allelochemical compounds that could be used as natural active inggredients to control weeds, especially the rhizome. Bioherbicide pre-emergence was expected to be able controlling weeds from germination so that the population of weeds will be reduced later. The objectives of this experiment were to obtain the alternative material for pre-emergence bioherbicide, to know the effectivity of pre-emergence Imperata cylindrica to growth, height and biomass of weeds, and also identify the dominant weeds in treatment area. This research conducted at Teaching Farm Politeknik Kelapa Sawit Citra Widya Edukasi Bekasi, from Januari until Juli 2021. This research was arranged in a factorial random block design with three replications and five treatments. The treatments are P0 (Control), P1 (Herbisida 1%), P2 (Bioherbicide 5%), P3 (Bioherbicide 10%), P4 (Bioherbicide 15%). Each of treatments repeated three times, so that there were 15 experimental unit. The data was analysis of variance. If the analysis variance test result was significant at 5%, then it continued by Least Significance Different Test (LSD Test). The result showed Imperata cylindrica could be as alternative material for pre-emergence bioherbicide and significantly affected to weed’s growth in 1 until 2 weeks after application (WAP), and heigt’s weed in 3 WAP. The lowest weed’s growth showed in control and not significantly different with all treatments. The weed dominance it showed in area is Axonopus compressus. The allelochemical compound contained in pre-emergence bioherbicide Imperata cylindrica are flavonoids 0,097% and tanin 0,105%.

Abstract

Dayak shallot has various phytochemical compounds that useful for health; people use it as medicinal plants. The technique of cultivating plants has not been informed completely. Hence, the research needs to be conducted to understand the competitiveness of weeds and the best planting space for optimal production. The research objectives are to obtain the effect of weed control and plant spacing for Dayak shallot growth and development. This research was used randomized block design two factors. The first factor is plant spacing and the second factor is weed control. There are four combinations of treatments between planting space and weed control. The treatment combinations used are: (1) Plant spacing of 15 cm x 15 cm with weed control; (2) Plant spacing of 15 cm x 15 cm without weed control; (3) Plant spacing of 30 cm x 30 cm with weed control; and (4) Plant spacing of 30 cm x 30 cm without weed control. Each treatment combination was repeated three times. The results showed that a combination of plant spacing and weed control was affected the percentage of flowering, the number of flowers on 4 and 6 days after planting, and the dry weight of Dayak shallot. The components of plant growth of Dayak shallot (plant height, number of leaves, root length, leaf biomass, root biomass, and total flavonoid content) was not affected by the combination of treatments. The dominant weed is Borreria latifolia, with SDR 30.623%.
