Field investigation was carried out at farmer’s field, Manaveli, Cuddalore (Taluk), Tamil Nadu during (January to December) during 2014 with sugarcane cv. EID PARRY 1110. The objectives of the study were to compare the conventional and modern irrigation practices and weed management practices for sugarcane. The main plot treatments were M1 - Conventional irrigation and M2 - Sub surface drip irrigation and the sub plot treatments were S1-Unweeded (Control), S2 - Hand weeding thrice (30, 60 and 90 DAP), S3 - Atrazine alone, S4 - Atrazine + 2,4-D, S5 - Atrazine + metribuzin and S6 - Atrazine + 2,4-D + Metribuzin. The treatments were compared in split plot design with 3 replications and a plot size of 40m2. Among the treatment combinations, application of atrazine @ 2.0 kg a.i ha-1 was sprayed on 3 DAP, 2,4-D @ 1.0 kg a.i ha-1 was sprayed on 21 DAP + metribuzin @ 1.0 kg a.i ha-1 was sprayed on 21 DAP under subsurface drip irrigation proved its superiority over the other treatments on weed population, crop nutrient uptake and cane yield when compared to conventional irrigation and unweeded control recorded higher weed population, lower crop nutrients removal and cane yield.
