Effect of plant geometry, fertility level and Zinc level on Kharif baby corn (Zea mays L.)

A Field experiments were carried out on sandy loam soil at Sabour during kharif season of 2018 to evaluate appropriate plant geometry, fertility levels and zinc lvel for baby corn (Zea mays L.). Experiment was laid out in split– plot design and replicated thrice with three plant geometry viz. P1 (40X20 cm), P2 (50X15 cm) and P3 (paired row at 50+30 x20 cm) in main plot, three levels of fertility (kg NPK/ha) viz. F1(120:60:60), F2 (150:75:75) and F3 (180:90:90) in sub plot whereas, two levels of zinc (kg/ha) viz., Z1 (2.5) and Z2 (5.0) in sub-sub plot. Significant increase in baby corn yield (14.34q ha-1 ), green fodder yield (267.822q ha-1 ) and net return (Rs 225774 ha-1 ) and B: C ratio (5.12) in baby corn was recorded with paired row plant geometry. The baby corn yield (13.92q ha-1 ), green fodder yield (278.91q ha-1 ) and net return (Rs 219108 ha-1 ) and B: C ratio (4.81) was significantly higher with fertility level 180: 90: 90 kg N P2O5 K2O/ha. Higher level of zinc had improved baby corn yield (13.38q ha-1 ), green fodder yield (277.7q ha-1 ) and net return (Rs 211821 ha-1 ) and B: C ratio (4.77) with successive increase in zinc level up to maximum level of fertility Zn2 (5.0 kg ha-1 ). | Effect of plant geometry, fertility level and Zinc level on Kharif baby corn (Zea mays L.)
