A field experiment was conducted at the Agricultural College Farm, Bapatla to study the effect of nitrogen levels and weed control practices in baby corn. Application of 180 kg N ha-1 recorded significantly more plant height compared to that of 150 and 120 kg N ha-1. Hand weeding twice (W2) recorded significantly more plant height. Higher ear and husk yields were obtained with the application of 180 kg N ha-1. Among weed control measures, hand weeding twice (W2) recorded significantly higher ear and husk yield. Higher fresh fodder fodder yield was obtained with the application of 180 kg N ha-1 but it was on a par with 150 kg N ha-1. Among weed control measures, hand weeding twice (W2) recorded significantly higher fresh fodder yield. But it was on a par with pendimethalin @ 1.0 kg a.i ha-1 + 2,4-D amine @ 0.58 kg a.i ha-1. The maximum nitrogen content and uptake in ear was recorded with the application of 180 kg N ha-1. Where as hand weeding twice (W2) recorded significantly higher nitrogen content and uptake in ear. Application of 180 kg N ha-1 recorded significantly higher crude protein over the 150 and 120 kg N ha-1. Among the weed control practices, hand weeding twice (W2) recorded significantly higher crude protein. The highest gross returns, net returns and returns per rupee investment were higher under hand weeding twice at all the levels of nitrogen.
