Abstract
The present investigation entitled, “Studies on the effect of foliar application of
urea and nano urea on growth and quality of apple nursery cv. Red Velox” was carried
in the Pandah Farm, Department of Seed Science and Technology, Dr YS Parmar University
of Horticulture and Forestry, Nauni, Solan HP during 2022-23. The experiment was laid in
Randomised Complete Block Design (RCBD), comprising 7 treatments viz, T1: Urea @
0.3%, T2: Urea @ 0.4%, T3: Urea @0.5%, T4: Nano urea @ 0.3%, T5: Nano urea @ 0.4%, T6:
Nano urea @ 0.5%, T7: Control. Each treatment was replicated thrice. Three foliar
applications of urea and nano urea were given at weekly interval in the month of July. Nano
urea @ 0.4 % (T5) significantly resulted in maximum plant height (183.21 cm), stem diameter
(15.70 mm), number of branches (3.00) per plant, number of leaves (62.07) per plant, leaf
area (33.51 cm2), leaf chlorophyll content (2.76 mg g-1), leaf N (2.43%) and K (1.63%)
content, fresh weight of shoots (246.30 g), dry weight of shoots (116.56 g), number of roots
(23.00) per plant, total root length (5.47 m), fresh weight of roots (38.23 g), dry weight of
roots (22.13 g), biomass of plant (138.69 g). From the present studies, it can be concluded
that Nano urea @ 0.4 % (T5) significantly enhanced the growth and quality of apple nursery
cv. Red Velox.
