Abstract
Investigations were undertaken at the Department of Agronomy)
College of Horticulture) Vellanikkara, Trichur, Kerala during 1996 - '97 to
standardise the agrotechniques in Indian sarsaparilla (Hemidesmus indicus
[Linn] R. Br).
The mam objectives of the study were to standardise the planting
material in Hemidesmus indicus and to arrive at the optimum spacing for
getting maximum yield. The study also aims to workout the optimum stage of
harvest so as to get the highest yield of good quality. The salient findings of
o
the study are abstracted below.
The nursery studies revealed that 5 cm long root cuttings planted
vertically formed the best propagule in Hemidesmus indicus. Hence the
experiment was carried out using 5 cm long root cuttings planted vertically.
The application of FYM @ lOt ha" and high density planting at (10 x 10 cm)
resulted in increased nutrient uptake and thus improved the growth and yield
of Hemidesmus indicus. The oil yield) water and alcohol soluble extract
obtained in this treatment was superior as compared to that with control plots
with~ut any FYM application. The available N) P20S) K20 and organic carbon
content of soil was more in heavily manured plots. The available N and P20S
left in the soil was higher in widely spaced plots (20 x 20 cm) where as
available K20 and organic carbon content more in dense planting of
10 x 10 cm.
The different stages of harvest were compared with regard to their effect
on growth and yield of hemidesmus. The nutrient uptake by the crop was
highest in the eight month stage and hence this particular treatment resulted in
the highest oil yield as compared to that in the other stages of harvest.
Excepting available N, the nutrients left in the soil was found to be decreasing
by eight month crop stage.
The interaction effect of spacing x FYM and stages of harvest showed
that the treatments receiving FYM @ lOt ha" and high density planting at
10 x 10 cm spacing when harvested at eight month stage, recorded the highest
oil yield. Also this particular treatment recorded highest root yield, total
returns and net returns as compared to the other treatment combinations.
