Abstract

ABSTRACT The critical period is a time when cultivated plants are very sensitive to the presence of weeds, so that the disturbance caused by them can reduce the final yield. So, no the entire growing period of plants is affected by weeds. This critical period related to the time of proper control, so that the presence of weeds does not always require control measures. This research aimed to determine the critical period for sweet corn (Zea Mays Saccharata Surt) against weeds and the effect of weeds on the growth and yield of sweet corn plants. This research was carried out at Gampong Mesjid, Kaway XVI, West Aceh regency, Soil Science Laboratory, Pest and Disease Laboratory, Faculty of Agriculture, Universitas Malikussaleh, North Aceh from February to April 2024. This research used an experimental method of randomized block design (RBD), single factor that consisted of 10 treatments with 3 replicating. P1: 0−15 DAP with weeds, P2: 0−30 DAP with weeds, P3: 0−45 DAP with weeds, P4: 0−60 DAP with weeds, P5: 0−Weedy harvest, P6: 0−15 DAP weeds free, P7: 0−30 DAP weeds free, P8: 0−45 DAP weeds free, P9: 0−60 DAP weeds free, P10: 0−DAP harvest free from weeds. The results showed that the critical period for sweet corn for weeds is determined at the age of 16−30 day after planting. Weed control carried out between 16−30 days of plant age will not inhibit the growth and yield of sweet corn plants. Keywords: Critical Period, Weeds, Sweet Corn.
