Bp. Nautiyal et al., Assessment of germinability, productivity and cost benefit analysis of Picrorhiza kurrooa cultivated at lower altitudes, CURRENT SCI, 81(5), 2001, pp. 579-585
Cultivation of Picrorhiza kurrooa Royle ex Benth, a small creeping, highly
medicinal and endangered species of alpine region was observed at comparati
vely lower altitude than its natural habitat. Germination was observed bett
er inside polyhouse at 15-20 degreesC temperature in sandy soil with litter
treatment and high-moisture content. Vegetative propagation was done succe
ssfully through stolon segments by using hormonal as well as convenient and
simple methods, viz. water-dip treatment and use of high-moisture trenches
for rooting in cuttings, which can be easily used for cultivation purpose
by local growers. Top segments were found more suitable for multiplication.
Yield measured in different landforms, i.e. raised and levelled grounds in
dicated that the latter was more suitable for better survival, growth and p
roduction. Similarly, intercropping with other economically beneficial plan
ts was successfully observed and Foeniculum vulgare and Solanum tuberosum w
ere recommended for intercropping. Forest litter was observed better for hi
gher production by using broad-leaf variety and maximum production was esti
mated at Pothivasa (1092 kg/ha). For cultivation of P. kurrooa, broad-leaf
variety, forest litter treatment, levelled ground and intercropping with pl
ants able to retain moisture in the soil for growing plants, and altitude o
f 2200 m were endorsed as best for higher production. Cost benefit analysis
after third year of cultivation indicated benefits of Rs 87,600/ha based o
n maximum production. Thus the cultivation of P. kurrooa can provide not on
ly an alternate income-generating resource, but can also provide the opport
unity for self-employment.
