Abstract: The experiment was conducted during 2012-13 and 2013-14 to study the effect of date of planting and crop geometry impacts on growth and yield of baby corn (Var. G-5414) in a split plot design with five dates of planting viz, October (D1), 1 November (D2), December (D3), January (D4) and February (D5) and three levels of plant population viz. 45 x 30 cm (S1), 2 3 4 5 1 45 x 20 cm (S2) and 45 x 10 cm (S3) with three replications. Plant height, corn yield and fodder yield were higher when 2 3 baby corn planted wider spacing of 45 x 30 cm. December sowing took the longest duration for 50% germination, which was at par with that of November sowing. Number of leaves per plant was the highest in February sowing and it did not vary with that of October sowing. Whereas, closer spacing of 45 x 10 cm resulted in shorter plant height and reduction of both corn and fodder yield. Days to 50% flowering did not vary among the spacing but this character did vary significantly across the sowing dates and the longest and shortest durations being in the December and February sowings respectively. The growth and yield parameters of baby corn were clearly indicative that they were thermo- sensitive and baby corn cobs and fodder yield are higher at closer spacing.
