ABSTRACT
The present research entitled s“Floral biology and manurial studie in clary sage (Salvia
sclarea L.)” were carried out in the experimental field as well as in laboratory of the Department of
Forest Products, COF, UHF, Nauni, Solan (H.P) during 2017-18. In the first experiment “Study of
floral biology on clary sage” was found to be herbaceous perennial, cross pollinated, aromatic herb
with profusely flowering verticillasters. Roots were cymose tap root system. Stems were erect, thick,
quadrangular and pubescent. Leaves of basal part were petiolate, broadly ovate shape, obtuse apex and
cordate base, crenate margin, pubescent surface with dark green colour arranged in opposite and
decussate manner. Inflorescence was comprised of verticillasters profusely branched spike with many
bluish to purplish flowers. Flowers were hermaphrodite, zygomorphic, gamosepalous, bilipped, upper
lip bilobed, lower lip trilobbed, two stamens, epipetalous, bicarpellary, syncarpous, superior, bifurcated
stigma; schizocarpic nutlet fruit with axile placentation. Seed germination percentage in laboratory
gave 86.67 ± 6.48 % and in open field gave 81.33 ± 2.77 %. In second experiment “Comparative
efficacy of nutrient management on clary sage” the growth parameters and essential oil content (%)
were investigated. In this experiment ten treatment consisting of control, NPK, FYM, vermicompost,
FYM+NPK, Vermicompost+NPK, Jeevamrit (jersey), Jeevamrit (desi), Panchagavya (jersey) and
Panchagavya (desi) were evaluated in RBD design with three replications in the field. The nutrient
combination of Vermicompost (2 t/ha) + NPK (90:60:30 kg/ha) gave the maximum value of growth
and yield parameter viz. spike length (67.30 cm), spike yield per plant (107.26 g), essential oil content
(0.18%), estimated spike yield/ha (11917.68 kg/ha) and estimated essential oil yield (21.45 l/ha) which
was followed by the combination of FYM (15 t/ha) + NPK (90:60:30 kg/ha). In the post-harvest soil
the status of mineralizable nitrogen, phosphorus, potassium and organic carbon were increased. Results
revealed that combined application of organic manures and inorganic fertilizers produced higher
biomass and oil yield as compared to control and sole application. Maximum Benefit:Cost Ratio
(1.69:1) was found in NPK+Vermicompost treatment followed by 1.53:1 in treatment NPK fertilizers
