Abstract
ABSTRACT
The present investigations entitled “Morphological and agro-economic studies of
Origanum vulgare L.” were carried out in the experimental field as well as in laboratory of the
Department of Forest Products, College of Forestry, Dr Y S Parmar University of Horticulture and
Forestry, Nauni, Solan (HP) during 2020-2021. In the first experiment “Morphological studies of
Origanum vulgare L.” was found to be perennial herb, erect, quadrangular, with several branches,
pubescent having distinct nodes and internodes. Leaves were opposite and whorled, pinnately
dissected and compound, estipulate having root system. Inflorescence of Origanum vulgare L.
composed of axillary pair of dichasial cymes that formed an apparent whorl. The flowers were
hermaphrodite, solitary on each axil, flowers bracteolate and white in colour. Calyx were 5, glandularhairy,
persistent, bilibiate and superior. Corolla was bilabiate (upper lip obsolete) and lower lip
3- lobed. Anthers were four in number, didynamous and epipetalous. Gynoecium with superior ovary
(4- lobed) with two carpels, anatropous, erect, epipetalous consisting of either unifid or bifid stigma.
Fruit composed of 4 nutlets (fleshy pericarp), cohering in pairs within the persistent calyx seed. In the
second experiment, “Studies on the influence of various organic manures, fertilisers, and harvesting
schedules in Origanum vulgare L.” Vermicompost (2t/ha) + NPK (90:45:30 kg/ha) had a substantial
effect on growth and yield in two harvests. The treatment combinations Vermicompost (2t/ha) + NPK
(90:45:30 kg/ha) had the highest fresh leaf weight per plant (23.58 g), dry leaf weight per plant
(8.38 g), total fresh aerial biomass yield (23.44 q/ha), total dry aerial biomass yield (7.61 q/ha) and
essential oil yield (9.92 l/ha). All the treatments viz. NPK (90:45:30 kg/ha), FYM (4t/ha), FYM (4t/ha)
+ NPK (90:45:30 kg/ha), Vermicompost (2t/ha), Vermicompost (2t/ha) + NPK (90:45:30 kg/ha),
Jeevamrit (3 splits (as BD + 30 DAT + 60 DAT)) performed better than control. Economic analysis of
Origanum vulgare L. revealed that Vermicompost (2t/ha) + NPK (90:45:30 kg/ha) had the highest
Benefit cost ratio of 1.56 which was followed by FYM (4t/ha) which had benefit cost ratio of 1.3.
