Abstract
A field experiment was conducted during kharif 2010 and 2011 at Instructional farm of Rajasthan College of Agriculture Udaipur, Rajasthan, India to study the effect of crop spacing (45 × 20, 60 × 15 and 90 × 10 cm), nitrogen levels (60, 90 and 120 kg ha-1) and plant growth regulators (control, N-acetyl Aspartate (NAA) at 40 ppm and mepiquat chloride at 200 ppm) on yield attributes, yield and economics of baby corn. The crop spacing 60 × 15 cm significantly influenced yield attributes. Maximum green cob yield, baby corn yield and green fodder yield was recorded at 60 × 15 cm spacing which was higher (14.0, 24.3 and 8.8%, respectively) over 90 × 10 cm. Increasing nitrogen levels up to 90 kg ha-1 markably improved the yield attributes, yields and net returns. Application of 90 and 120 kg N ha-1 exhibited significant increase in green cob yield over 60 kg N ha-1. The results revealed that application of nitrogen up to 90 kg ha-1 level significantly increased green cob yield and baby corn yield in tune of 20.5 and 23.6% as compared to 60 kg N ha-1. The mepiquat chloride at 200 ppm exhibited highest yield parameters viz. cob length, cob girth, cob weight, corn length, corn girth, corn weight and cobs plant-1 . The crop sprayed with mepiquat chloride produced highest green cob yield (5903 kg ha-1), baby corn yield (2083 kg ha-1) and this was comparable with application of NAA. In case of green fodder yield, NAA at 40 ppm produced significantly highest green fodder yield (26.9 t ha-1) over mepiquat chloride at 200 ppm (22.1 t ha-1). Key words: Spacing, nitrogen levels, plant growth regulator, baby corn.
