Effect of Foliar Application of Nano Urea on Growth and Flowering of Rose cv. Gladiator

Abstract

The present experiment was carried out at Instructional Unit, College of Horticulture, Junagadh Agricultural University, Junagadh (Gujarat), in the Rabi seasons of the year 2022-23 and 2023-24 under open field conditions using Randomized Block Design with seven treatments and three replications to find out the effect of nano urea on growth and flowering of rose cv. Gladiator. The pooled results revealed that treatment T1- recommended dose of fertilizer (40:20:40 g NPK/plant) gave maximum increase in plant height (39.86 cm), maximum increase in plant spread (1544.13 cm2) and number of flowering shoots per plant (19.89), but found at par with treatment T7- 75 percent recommended dose of nitrogen + 3 spray nano urea (4 ml/l). All the parameters were found lowest in treatment T2- 75 percent recommended dose of nitrogen + 2 spray nano urea (2 ml/l). Maximum stem diameter (1.89 cm) was recorded with treatment T7 followed by treatment T6- 75 percent recommended dose of nitrogen + 3 spray nano urea (3 ml/l). Flowering parameters viz., days taken for flower bud appearance after pruning and flowering after pruning remained non-significant by application of different treatments.
