Abstract

Research into the critical phase of weed competition in maize aims to determine weed control at the right time. The study used a randomized block design consisting of eight treatments with weed-free (WWF) and weed-free (WF) plant age periods up to 10, 20, 30, 40, 50, 60, 70, and 80 days after planting (DAP). Each treatment was randomly repeated in three blocks, resulting in 54 experimental units The observation parameters include weed population, dry biomass weight of weeds and maize, plant height, leaf area, ear length, ear diameter and dry weight of maize kernels per plot. Data analysis using analysis of variance and William's statistical test. The results of the study showed that the critical period for corn competition with weeds on dryland was about 20 - 30 DAP when the corn was planted. If weeds are removed after the plants are more than 30 days old, the harvest cannot be saved. Plants competing with weeds for 40, 50, 60, 70, and 80 days experienced yield reductions of 60.32%, 82.84%, 98.66%, 99.99%, and 99.99%, respectively. In contrast, plants that were only weed-free up to the age of 10, 20, and 30 days showed yield losses of 98.66%, 80.16%, and 61.40%, respectively. It is recommended to start controlling corn weeds on dry land 20 days after planting and to avoid weeding 30 days after planting.

Abstract

This research aims to determine the Poaceae weed species that have a significant effect on corn yield loss in dry land. The research method was descriptive and data collection using survey techniques in 10 sample plots measuring 1 m2 which were placed using random sampling. Observation parameters include the number of species and populations of weeds, the population of corn plants in plot-1 and the dry biomass weight of weeds and corn in plot-1. Quantitative data analysis by calculating relative density, relative frequency and relative dominance values ​​to calculate the importance value index and Summe Diminance Ratio (SDR). The results showed that the diversity, evenness, dominance and abundance of Poaceae weeds in corn plants in dry land was high. So it was found that seven species of weeds were dominant and continued to exist while the corn was growing, namely Paspalum vasginatum Sw., Leersia hexandra Sw., Digitaria longiflora (Retz.) Koel., Digitaria ciliaris (Retz.) Koel., Cynodon dactylon L., Eleusine indica Gaertn., and Panicum repens L. The competitiveness and ability to reduce corn yields of the weeds Paspalum vasginatum, Leersia hexandra and Digitaria longiflora are higher than other weeds, so that corn yield losses due to competition reach 16.45%, 7.48% and 4.40%. The weeds Brachiaria reptans, Axonopus compressus and Echinochloa colonum do not need to be controlled in corn after the plants are 45 DAT, because their competitiveness and ability to eliminate crop yields is very low.
