Abstract

The investigation was conducted with an aimed to study the effect of nano fertilizers (nano urea, nano
diammonium phosphate) and liquid micronutrients on flower yield and flower quality of gerbera (Gerbera
jamesonii) cv. Toro Rosso under shade net conditions during the late winter seasons of the year 2024-2025. This
study involved seven treatments in a completely randomized design with three replications. Among different
treatments T6 was significantly resulted with minimum number of days taken to first flower bud initiation (45.73
days), days taken to first flower bud opening (65.20 days), scape bending curvature (11.42°) and maximum flower
diameter (11.93 cm), flower stalk length (64.17 cm), flower stalk diameter (8.30 mm), fresh weight of flower (34.5
g), longevity of flowers on the plant (15.53 days), vase life in distilled water (9.06 days), flower yield per plant
(2.40) and maximum total flower yield per plant at the 150 days after planting (7.13) was recorded in June, 2024.
Based on the significant results from the study it was concluded that foliar application of nano fertilizers and
liquid micronutrients of T6 [75% N + 75% P2O5 + 100% K2O + nano urea @ 3 ml/L (Fortnight intervals from 30
days onwards up to 150 days) + Liquid micronutrients @ 2.5 ml/L (Fortnight intervals from 30 days onwards up
to 150 days)] was best for all the flower, flower yield and quality attributes of gerbera.
