FOLIAR SUPPLEMENTATION OF COPPER BASED ZINC NANO FERTILIZER ON GROWTH AND FLOWERING OF LISIANTHUS

Abstract

A field experiment was conducted in the Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka during the period from October 2019 to April 2020 to evaluate the effect of foliar application of supplement copper based zinc nano fertilizer on three lisianthus varieties. Lisianthus varieties viz. V (Light Pink), V 3 1

(Purple Picotee), V (Super Magic Type Blue); and copper based zinc nano fertilizer application with different concentration in: N (Control; No nano fertilizer application), N 1 (1ml/L), and N 2 0 (2ml/L) were used in this experiment arranged in Randomized Complete Block Design with three replications. Data on growth and flower yield attributes parameters were collected in which all the treatment showed significant variations. Among varieties, number of branches (4.9), stem length (55.3 cm), no. flower buds/stem (13.6), no. of flowers/plant (37.6), vase life (17.7 days) were observed in V (Purple Picotee) which is an early variety among the three varieties whereas minimum in V 1 (Light Pink) is a late variety. Again, 2ml/L copperbased zinc nano fertilizer application influenced growth characteristics of plant, where

tallest

plant height (78.8 cm), maximum number of leaves (104.3), SPAD value (56.7), stem diameter (5.4 mm), stem length (56.8cm) were recorded. Furthermore, maximum flower yield per hectare (9.1million) were found in V 2 1 N and minimum (2.1 million) in V 2 N . In view of overall performances, Purple Picotee lisianthus with the application of 2ml/L of copper based zinc nano fertilizer would be the potential for flower yield as well as quality.
