A field experiment was conducted at Agricultural Research Station, Ummedganj, Kota under vertisol of Rajasthan during kharif 2009 & 2010. This is situated in between 250 11'N latitude & 750 54' E longitudes with an altitude of 273 m mean sea level. The objectives of this study were to study the effect of nitrogen levels and weed control methods on growth, yield attributes and yield of rice. The experiment was laid out in split plot design in three replications with three levels of nitrogen (N Kg ha-1) in main plots, while five weed management practices in the sub-plots of each main plot. The results revealed that the rice variety IR-64 recorded maximum grain (3.46 t ha-1), straw (4.84 t ha-1) and biological yield (8.30 t ha-1) with the application of 125 Kg Nha-1 under aerobic conditions which was statistically at par with application of 100 kg N ha-1. On the other hand, different weed control practices also gave significantly higher grain yield of aerobic rice. The application of Pendimethalin @ 1.0 kg a.i. ha-1at 2 DAS + Rice : Dhaincha (1:1) + 2,4-D Na salt @ 0.80 kg a.i. ha-1at 25 DAS recorded excellent performance and contributed grain, straw and biological yield of 3.98, 5.55 & 9.53 t ha-1, respectively. Weed dry weight was recorded at 55 DAS showed that application of Pendimethalin @ 1.0 kg a.i. ha-1at 2 DAS + Rice : Dhaincha (1:1) + 2,4-D Na salt @ 0.80 kg a.i. ha-1at 25 DAS recorded significantly lowest weed biomass as compared to other weed control treatments
