3.1.3 Interaction of Variety and N-Level on the Growth Parameters of Baby Corn
Interaction effects of variety and N fertilizer was found significant for plant height at all growth stages (Figure
10). The tallest plant was obtained from Shuvra at 200 kg N ha-1 and the shortest from BARI sweet corn-1 at 0
kg N ha-1 at all growth stages. Interaction between variety and N fertilizer rates was found significant for days to
first tasseling and first silking (Table 2). Hybrid baby corn-271 took maximum days (83.0) for tasseling with 200
kg N ha-1 whilst BARI sweet corn-1 at 160 kg N ha-1 took the minimum (65.3). Hybrid baby corn-271 took
maximum days (87.7) for silking with 200 kg N ha-1 and BARI sweet corn-1 with 160 kg N ha-1 took the
minimum days (70.0). In general, less period of harvest (5-6 days) was needed in Hybrid baby corn-271 and
Shuvra compared to Khoibhutta and BARI sweet corn-1 (7-10 days) at all rates of N-fertilizer. Interaction of
