A field experiment was conducted at the Agricultural College Farm, Bapatla, to study effect of varying levels of nitrogen and intercropping on growth, yield attributing characters and yield of baby corn (Zea mays L.). The treatments consisted of C1: Sole baby corn, C2: Baby corn in paired row, C3: Baby corn in paired row + Soybean, C4: Baby corn in paired rows + Blackgram, C5: Baby corn in paired rows + Greengram in factor – A and N1= 100 % RDN, N2= 75% RDN and N3= 125% RDN in factor –B of Randomized Block Design with factorial concept and the treatments were replicated thrice. Significantly the highest baby corn cob yield (17048 kg ha-1), ear yield (5597 kg ha-1), husk yield (11450 kg ha-1), green fodder yield (58.8 t ha-1), nitrogen uptake (192.54 kg ha-1),were recorded in Baby corn in paired rows + Greengram. Application of 125% RDN gave the highest baby corn cob yield (17048 kg ha-1), ear yield (5597 kg ha-1),husk yield (11450 kg ha-1), green fodder yield (58.8 t ha-1), nitrogen uptake (207.77 kg ha-1). Gross and net return registered the lowest and highest gross & net returns (Rs. 1,38,146 &110809) and (Rs. 2,24,880 &195651) in baby corn sole crop with 75% RDN and baby corn + greengram with 125%,RDN respectively.
