An experiment was conducted during kharif season, 2010 and 2011 at Rajasthan College of Agriculture Udaipur, to study the effect of crop spacing (45cm × 20cm, 60cm × 15cm and 90cm × 10cm), nitrogen levels (60, 90 and 120 kg ha-1) and plant growth regulators (control, NAA @) 40 ppm and Mepiquat chloride @ 200 ppm) on yield, nutrient content and uptake of baby corn. The higher green cob yield, baby corn yield and green fodder yield was significantly recorded at 60cm × 15cm spacing over 90cm × 10cm. Increasing nitrogen levels up to 90 kg ha-1 showed marked improvement in green cob yield and baby corn yield, but in case of green fodder yield, nitrogen concentration and uptake by fodder recorded significantly highest with 120 kg ha-1. The crop sprayed with Mepiquat chloride @ 200ppm produced the highest green cob yield (5903.03 kg ha-1), baby corn yield (2082.64 kg ha-1) and this was comparable with application of NAA, in case of green fodder yield NAA @ 40 ppm produced significantly higher green fodder yield (26.88 t ha-1) over Mepiquat chloride @ 200 ppm which produced lowest green fodder yield (22.13 t ha-1).
