Abstract
The present experiment entitled “Effect of different media composition and
shade levels on growth and marketability of tropical ornamental foliage plants” was
carried out during the winter season of the year 2018-19 at the Floriculture Research
Block, College of Horticulture, Mojerla.
The results revealed that significant differences were recorded in
different ornamental foliage plants (Dieffenbachia, Syngonium, Philodendron)
Among the different compositions of media, M2 combination of media Red Earth +
Cocopeat (1:1) at 120 days after planting (DAP) recorded maximum leaf length
(26.26 cm,10.80cm, 13.86 cm), leaf width (10.00 cm, 9.00 cm, 3.80 cm), leaf area
(201.80 cm
2 ,132.95 cm2
, 68.11 cm2
), length of the petiole (9.18 cm, 23.07 cm, 4.50
cm), height of the plant (43.58 cm, 32.25 cm, 17.75 cm), number of leaves (10.62,
10.87, 6.62), length of the internodes (2.71 cm, 5.47 cm, 1.30 cm), shoot fresh
weight (69.00 g, 22.91 g, 8.22 g), number of roots (14.25, 6.62, 6.75), length of the
roots (49.25 cm, 27.01cm, 34.76 cm), fresh weight of roots (36.13 g, 19.5 g, 7.70 g)
over other combination of media.
Among the shade levels, 80 % shade recorded maximum leaf length (27.10
cm, 9.86 cm, 16.80 cm), leaf width (10.11cm, 8.28 cm, 5.08 cm), leaf area (210.10
cm
2
, 132.95 cm2
, 86.20 cm2
), length of the petiole (10.23 cm, 24.00 cm, 4.58 cm),
height of the plant (50.36 cm, 35.13 cm, 23.67 cm), number of leaves (9.87, 10.50,
7.25), length of the internodes (2.71 cm,7.12 cm,1.75 cm), shoot fresh weight (71.90
g, 22.30 g, 10.20 g ), length of the roots (47.70 cm, 26.70 cm, 39.90 cm), fresh
weight of roots (36.25 g, 18.50 g, 9.80 g) over other combination of media.

The interaction between different compositions media and shade levels had
significant influence on plant height, plant spread, number of leaves, number of
roots, leaf quality, leaf colour at final stage. M2 combination of media (Red
Earth+Cocopeat (1:1) and Shade level (80% shade) registered significantly
maximum leaf length (30.50 cm, 11.80 cm, 20.30 cm), leaf width (11.70 cm, 9.75
cm, 5.55 cm), leaf area (241.90 cm
2
, 140.90 cm2
, 98.30 cm2
), length of the petiole
(11.85 cm, 27.90 cm, 6.30 cm), height of the plant (55.90 cm, 38.60 cm, 27.10 cm),
number of leaves (12.00, 13.00, 10.00), length of the internodes (3.40 cm, 8.55 cm,
2.15 cm), shoot fresh weight (87.05 g, 26.70 g, 13.30 g), number of roots (17.00,
8.00,10.00), length of the roots (60.30 cm, 30.40 cm.52.70 cm), fresh weight of
roots (44.50g, 20.50 g, 12.30 g).
Among the different compositions of media, M2 combination of media (Red
soil + Cocopeat (1:1)) recorded less number of days taken to bud sprouting (27.18
days, 30.50 days, 30.71 days) and full leaf expansion (8.60 days, 8.62 days, 7.50
days ). where as shade levels of 80 % shade recorded less number of days taken to
bud sprouting (30.76 days, 29.10 days, 29.70 days) and full leaf expansion (9.50
days, 9.12 days,7.00 days).
The data on quality of plants indicated that, among the different compositions
media, M2 combination media (Red Earth+ Cocopeat (1:1)) recorded significantly
good quality and colour of the leaves. Among the shade levels, 80 % shade
recorded the excellent quality and colour of leaves.
Data on economics indicated that among all media compositions and shade
levels, interaction effect of M2 combination of media (Red Earth + Cocopeat (1:1)
and 80 % shade level recorded maximum gross returns (39600.00, 38800.00,
46750.00), net returns (27050.00, 21750.00, 34200.00) and B : C (2.15, 2.09, 2.72)
ratioes over other treatments.
