Field demonstrations were conducted during rabi season for two years in seven locations of Tiruppur District, Tamil Nadu state to study the weed density under drip fertigation and conventional method of cultivation (Farmer's practice). Nine weed species emerged with a frequency of more than 50% irrespective of the locations. Drip fertigation with recommended dose of fertilizers (RDF) produced the highest bulb yield of onion when compared with the conventional method of cultivation. Total population of weeds and weed dry weight were minimum under drip fertigation.
