Abstract
An investigation on the “Standardization of Vegetative propagation
of Morinda citrifolia L. var. citrifolia by cuttings” using various inputs was
carried out in a medium cost poly house during 2008-09 at Gandhi
Krishi Vignana Kendra, University of Agricultural Sciences, Bengaluru.
Experiments were conducted to standardize the vegetative propagation of
noni cuttings using growth regulators with sand as rooting medium and
organic preparations with different rooting media.
Among the different nodal cuttings and growth regulators
treatments triple nodal (12 cm) cuttings were significantly superior in
time taken for sprouting (18.64 days), number of roots (2.87), root length
(4.88 cm) and survival rate (46.33%), whereas IBA 3000 ppm recorded
significant number of roots (2.96), length of root (7.80cm), and survival
rate (72.22%), their interaction recorded highest number of roots (2.89),
root length (11.44 cm) and survival rate (73.33%).
Among the organics panchagavya recorded highest number of
roots (18.27), root length (7.96 cm) and survival rate (70.67%) whereas
the vermiwash recorded 22.96 days to sprout, 95.33 per cent rooting,
13.07 roots, 4.00 cm root length, and 66.00 per cent survival rate.
Among the different rooting media used, mixture of red soil, sand
and FYM (1:1:1) was found to be significant with higher rooting (88.67
%), number of roots (14.96), longest root (4.53 cm) and survival rate (64
%). The combination of panchagavya with 1:1:1 rooting mixture of red
soil, sand and FYM was found to be significantly superior with respect to
root and shoot parameters. This combination recorded maximum
number of roots (24.11) and longest root (10.82 cm).
The present study can be concluded as, triple nodal cuttings
coupled with IBA 3000 ppm is the best treatment for propagation.
Whereas panchagavya or vermiwash coupled with rooting media
comprising of 1:1:1 mixture of red soil, sand and FYM is best for organic
cultivation.
