Abstract
A field experiment was carried out at the Floriculture Unit of Kittur Rani
Channamma College of Horticulture, Arabhavi, University of Agriculture
Sciences,Dharwad during 1996-97 and 1997-98, to study the effect of
organic,inorganic and in situ vermiculture on growth and flower yield of Jasmine.
To achieve the objectives of the study, two separate experiments were carried out.
In the first experiment, all the growth components of Jasminum sambac
Ait. were better in the plants supplied with 50 per cent RDF along with vermicompost
(2 or 4 or 8 kg/plant) and RDF + RDFYM (120:240:240 g NPK + 20 kg FYM/plant).
The plants supplied with vermicompost alone (2 or 4 or 8 kg/plant) or in
combination with 50 per cent RDF were early to initiate flowering. Good quality
flower buds were produced by the plants which received 50 per cent RDF +
Vermicompost (2 or 4 or 8 kg/plant) and in situ vermiculture (50 or 100 worms/plant)
and RDF + RDFYM. The ftower yield was maximum in the plants which received
RDF -I- RDFYM and 50 per cent RDF + vermicompost (2,4 or 8 kg per plant).
In the second experiment, the growth parameters which were influenced
mostly by N were optimum in lower levels of N, but luxur-iant in higher levels at the
cost of flowering. The nutrient combination of 60:120:120 of per plant of NPK along
with 20 kg FYM per plant was found optimum to achieve the optimum growth and
flower yields in the first two years of planting in Jasminum auricuiatum Vahl.
