Implication

Randomized field experiment reveals optimal baby corn yields at high zinc levels with narrow spacing, suggesting density drives field productivity.

Key Points

To evaluate the impact of different zinc sulfate levels and planting spacings on the growth parameters, cob characteristics, and total yield of baby corn.
Conducted a field trial using a Randomized Block Design with nine treatments replicated three times during the 2020 Zaid season in sandy loam soil (pH 7.1).
Tested three zinc sulfate application rates (15, 20, and 25 kg/ha ZnSO4) across three plant spacing configurations (40 × 20 cm, 50 × 20 cm, and 60 × 20 cm).
Application of 25 kg/ha ZnSO4 with 60 × 20 cm spacing maximized individual plant growth metrics, including plant height (168.13 cm), leaves per plant (13.25), dry weight (90.96 g), cob weight with husk (47.92 g), and cob weight without husk (22.70 g).
Application of 25 kg/ha ZnSO4 with 40 × 20 cm spacing achieved the highest area yields, recording cob yield with husk of 14.63 t/ha, dehusked cob yield of 5.09 t/ha, and green fodder yield of 28.83 t/ha.
Treatment with 20 kg/ha ZnSO4 at 40 × 20 cm spacing produced the maximum crop growth rate at 30.45 g/m²/day.
