The results of field experiment conducted at Agricultural Research Institute, ANGRAU, Rajendranagar, Hyderabad during rainy (kharif) season of 2005 and 2006 revealed that recommended dose of N (RDN) through fertilizer application (90 kg N ha-1) recorded significantly higher number of cobs plant-1, cobs ha-1, baby corn green ear yield, stover yield and nutrient uptake over combined application of 75% N through fertilizer + 25% N through Neem cake, 50% of N through fertilizer + 50% of N through Neem cake. However, the number of days taken to first harvest and harvest duration (First harvest to final harvest) were not influenced by N management practices. Higher net returns (`30767 ha-1) and B:C ratio (2.3) were obtained with recommended dose of N application. Out of all the cultivars tested VL-78 recorded significantly higher baby corns plant-1 (2.92), more green ear weight (23.3 g), harvest duration (25.2 days), baby corn yield (5511 kg ha-1), N and K uptake, also net returns (`36693 ha-1) and B:C ratio (2.5). Significantly higher net returns were obtained by cultivar VL-78 with combined application of 75% N through fertilizer + 25% N through Neem cake.
