DAP = day after planting, B = boron; L = light; V = variety; , columns having the same letter(s) are insignificant and different letter(s) are statistically significant, P = probability. Means were separated by Tukey’s test at , B₀ = 0 kg B ha⁻¹ (control), B₁ = 1 kg B ha⁻¹, B₂ = 2 kg B ha⁻¹, L = normal day light + 6 h extended red light at night (≈18 h light), L₀ = normal day light (≈12 h light), V₁ = Dhaka-1, and V₂ = BARI Chinabadam-8.
