Abstract
Baby corn has a high monetary value, which allows for crop diversification value addition, and revenue generating. As a result, agro-techniques for its cultivation must be standardised. Hence, a field experiment was conducted during the rabi season in black clayey soils at Fodder Production Farm of Livestock Research Station, Sri Venkateswara veterinary University, Lam Farm, Guntur-522034, Andhra Pradesh, India to find out the Influence of different levels of phosphorus (40, 50, 60 kg/ha) and various row spacings (40 x 15 cm, 45 x 15 cm, 50 x 15 cm) on growth and yield of baby corn. The experiment was laid out in Randomised Block Design with nine treatments each replicated thrice. It is observed that crop established with 50 x 15 cm spacing along with application of 50 kg/ha Phosphorus produced Maximum growth attributes viz. Plant height (161.10 cm), Numbers of leaves (12.47), Plant dry weight (90.21 g/plant) and yield attributes viz. No. of cobs/ plant (4.03), Length of cob (24.34 cm), Length of corn (9.47 cm), Cob weight (56.38 g), corn weight (11.61 g), Cob yield (35696.67 kg/ha), Corn yield (7560 kg/ha).
