Sweet corn (Zea mays L. var. Saccharata Sturt), is a variety of maize with a high sugar content. It is  also called Indian corn, sugar corn and pole corn. Nature of weed problem in Rabi maize is quite different from that of the rainy season maize. In the rainy season, emergence of maize and weed start simultaneously in which first 20-30 days are most critical looking to crop-weed competition while in winter maize, weeds emerge most often after the first irrigation. However, wider row spacing and liberal use of irrigation and fertilizers lead to more growth of weeds (Porwal  2000). Therefore, the study was carried out to find economically effective method of weed control for realizing higher productivity and profitability of sweet corn.
