Abstract
The present investigation entitled, “Studies on the effect of EMLA 111 rootstock on
growth and leaf nutrient status of exotic apple cultivars” was undertaken at Experimental
Farm of Department of Seed Science & Technology, Dr. Yashwant Singh Parmar University
of Horticulture and Forestry, Nauni, Solan (HP) during 2021-2022. The experiment was laid
out in a Randomized Complete Block Design (RCBD), with six different exotic apple
cultivars replicated four times. The plant spacing in bud wood bank was 2×2 m. Three plants
per replication were randomly selected for recording observations on growth and leaf nutrient
status of exotic apple cultivars. Among the different cultivars maximum plant spread (1.44
m2), incremental growth in tree height (62.34 cm), internodal length (4.02 cm), number of
shoots per plant (10.00), shoot length (74.07 cm), annual shoot growth (36.03 cm), total
number of leaves per plant (43.16), leaf chlorophyll content (2.41 mg g-1), leaf area (28.53
cm2), leaf area index (1.39) was recorded in cultivar Gala Schnico on EMLA 111. However,
the maximum numbers of graftable bud sticks (25.50) were also collected in cultivar Gala
Schnico on EMLA 111. Leaf N (2.16%), leaf P (0.18%) and leaf K (1.95%) was found
highest in cultivar Dark Baron Gala on EMLA 111 rootstock
