up during 2002-2003 at College of Horticulture, Vellanikkara, Thrissur. The
experimental site was Cashew Research. Station, Madakkathara, Kerala
Agricultural University. It consisted of two parts viz., management practices for
cashew root stock production and the management practices of cashew grafts.
The experiment on the management practices for cashew root stock
production was conducted to select the best organic sources (cowdung, poultry
manure, coirpith compost) of nutrients in the potting media and to find the effect
of Azaspirillum, Phosphorus Solubilizing Bacteria and Arbuscular Mycorrhizal
Fungi inoculation on the growth of root stocks.
The-bulk density and particle density were found to be decreased and by
the application of organic manure in the potting mixtures and the lowest was
found with coirpith compost. The pore space and water holding capacity were
increased by the organic manur~s in the potting mixtures and the maximum was
observed with coirpith compost.
In all the organic manure containing potting mixtures combined
inoculation of Azospirillum, PSB and AMF decreased the days taken for
germination, compared to single inoculation and the minimum was observed in
coirpith compost applied treatment. The maximum germination percentage was
found with AMF inoculation in cowdung containing potting mixture and
Azospirillum+ PSB+ AMF inoculated potting mixtures of cowdung and coirpith
compost. Among the different potting mixtures, a higher growth rate of seedlings
were observed in the potting mixture containing sand:soil:cowdung+
Azospirillum+ PSB+ AMF .
. ,
The care and management of grafts in the nursery involved soil and foliar
application of nutrients in the second part of the experiment. Here all the
treatments were having the" same potting mixture (sand:soil:cowdung+
" .
Azospirillum+PSB"+AMF) and nutrient supplementation through various sources
were given at 1 MAG and 3 MAG through soil and foliar application respectively.
The performance of the grafts were found "better With the soil application of 100
ml of decanted extract of groundnut cake + 100 ml of 17: 17: 17 mixture (prepared
by 100g 17:17:17 mixture added in 10 1 water) "at 1 MAG followed by 2%
17:f7:17 spray at 3 MAG.
