Abstract

One of the step of corn cultivation is plant maintenance. It is intended for control of pests or weeds around the cultivated area. Weeds are capable to decrease both quality or quantity of crops. The research is aimed at dentify the types of weeds that grow on the Pertiwi variety corn cultivation land, and determine the dominant weeds on the land. The study was conducted by the square method by spreading a frame measuring 50 cm x 50 cm on the cultivated land of the Pertiwi variety of maize 10 times, weeds that entered into the frame then recorded the type and amount, and determined the dominant weed. The results showed that there were 11 species of weeds that grow in the corn cultivation of Pertiwi varieties, including 6 species of narrow-leaved weeds, 2 species of sedges, and 3 species of broad-leaved weeds. Narrow leaf weeds (grasses) are the most widely grown weeds in the cultivated land of Pertiwi varieties. Weeds that dominate the cultivated land of maize varieties are Cynodon dactylon with  SDR value of 19.95, and Echinochloa colona with SDR value of 10.44. The Poaceae / Graminae family is the main weed family that grows in the cultivated land of the Pertiwi variety.
