Interactive effects of nitrogen dose and split application schedule on growth and floral yield of Lisianthus (Eustoma grandiflorum)
Abstract
A field experiment was conducted at the Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka, during the period from September 2025 to January 2026 to study the effect of nitrogen doses and split application schedule on growth and floral yield of Lisianthus (variety, SAU Purple Nandini). Three nitrogen doses, namely N₁ = 112 kg ha⁻¹ (BARI recommended dose for marigold), N₂ = 150 kg ha⁻¹, and N₃ = 188 kg ha⁻¹, along with three split application treatments: S₁ (full dose applied as basal), S₂ (two splits: 50% basal + 50% at 30 days after transplanting), and S₃ (three splits: 33% basal + 33% at 30 DAT + 34% at 60 DAT), were evaluated in a Randomized Complete Block Design (RCBD) with three replications. Data on different growth, flower yield, and quality attributes were recorded, and all treatments showed significant variations. Among nitrogen doses, the maximum number of flower buds/plant (14.1), flower diameter (7.6 cm), and flower stalk/ plant (4.45) were found in the N3 treatment. Among the split application maximum number of flower buds/plants (12.8), and flower diameter (6.8 cm) were found in S3. The effect of nitrogen doses and split application showed that the maximum number of flower buds/ plant (15.3) was found in N3S3, and the minimum number of flower buds/plant (8.0) was found in N1S1. The study showed that the higher nitrogen doses with split application would have the potential for Lisianthus production.
