Baby corn is the female green ear of the corn plant harvested before fertilization and its cultivation is a profitable alternative for small farms. The objective of this study was to evaluate the effect of row spacing (0.5, 0.6, 0.7, 0.8 and 0.9 m) and seeding rate (13, 15, 17 plants per meter) on baby corn production. The study was conducted at State University of Northern Paraná, Luiz Meneghel Campus, southern Brazil with a 5 × 3 factorial scheme (spacing, density) arranged in a randomized block design with four replications. Corn hybrid AG1051 was grown in 5-m long and 6.5-m wide plots. The yield components evaluated were stalk diameter, length and diameter of the unhusked and husked ear, shape index, unhusked yield, husked yield, and marketable yield. Stalk diameter and ear size were significantly affected by row spacing. Ears were not perfectly cylindrical. Baby corn yield was not affected by either row spacing or planting density.
