Description ABSTRACT
The present investigations entitled “Studies on the development of cultivation practices of
Asparagus racemosus Willd. under mid hill conditions of Himachal Pradesh” was carried out in
the experimental farm as well as in laboratory of department of Forest Products, College of Forestry,
Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan (H P) during 2011-2015. The
study was undertaken with the objectives (a) Morphological and phenological studies of A. racemosus
(b) standardization of nursery raising techniques (c) standardization of cultivation technology and
estimation of cost of cultivation and benefit cost ratio. The plants under study were perennial climber
with fasciculated tuberous roots. Pollen were observed bicolpate, elliptical in shape when shed and
circular when moist. Cladodes per tuft were observed 5-10 in number. Flowering occurred from
September to December in 3 flushes under open conditions and September to January in 4 flushes
under polyhouse conditions. Seed ripened from October even upto March-April. Very low seed set
was observed in the experimental area. Seed sown during May month in Soil + Cocopeat +
Vermicompost (1:1:1) media under protected conditions resulted in maximum germination
percentage, shoot and root length. Pre-sowing treatment of seeds with H2SO4 (10%) for 30 minutes
resulted in maximum germination percentage and mean daily germination. Seeds stored in polythene
bags under refrigerated condition retained viability for longer period. Field plantation at 30 cm x 45
cm spacing after 24 months of planting resulted in higher underground biomass yield/ha (28.46 q/ha).
NPK @ (60:30:30 kg/ ha) combination gave maximum underground biomass yield after 24 months of
planting (20.27 q/ha) which was followed by combination of FYM + Vermicompost + PSB (5t : 2t :
5kg) (18.41 q/ha). Higher benefit : cost ratio (3.65) was obtained with the application of NPK @
(60:30:30 kg/ha) which was followed by FYM + PSB @ (5t : 5kg) i.e. 2.65
