| dc.description.abstract | ABSTRACT The present investigations entitled “Evaluation of accessions and standardization of cultivation practices of Acorus calamus Linn.” 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 2015-16 & 2016-17. In the first experiment “Morphological studies of A. calamus under natural conditions” Acorus calamus Linn. was found to be perennial, semi-aquatic, monocot, aromatic herb with creeping rhizomes. Rhizomes were cylindrical or somewhat compressed, creeping, horizontal, greenish white on the outside, pinkish white and spongy inside with distinct nodes and internodes. Leaves were linear, smooth, erect, distichously alternate, ensiform, base equitant, moderate yellow green in colour and having a single prominent mid vein with margin almost entire. In second experiment “Evaluation of different accessions of A. calamus (Bach)” accession C4 (Nikyar) gave maximum fresh rhizome weight (31.29 g/plant), dry rhizome weight (15.33 g/plant), estimated fresh rhizome yield (17.37 q/ha), estimated dry rhizome yield (8.51 q/ha), essential oil content in fresh rhizome (1.07 %) and estimated essential oil yield (18.57 kg/ha) among all the ten accessions evaluated. No inter-accession difference in leaf shape, colour and rhizome colour were noticed amongst the ten accessions evaluated. In third experiment “Effect of different node cuttings on growth and yield of A.calamus” three node cutting (N3) of rhizome gave maximum fresh rhizome weight (28.13 g/plant), dry rhizome weight (13.78 g/plant), estimated fresh rhizome yield (31.25 q/ha), estimated dry rhizome yield (15.32 q/ha) and estimated essential oil yield (16.80 kg/ha) whereas higher benefit cost ratio (1.80) was obtained from one node cutting of rhizome which was followed by two node cutting of rhizome (0.93). In fourth experiment “Effect of different planting time and harvesting schedules on growth and yield of A.calamus” crop planted in July and harvested after 2nd growing season resulted in maximum fresh rhizome weight (33.85 g/plant), dry rhizome weight (15.91 g/plant), estimated fresh rhizome yield (37.61 q/ha), estimated dry rhizome yield (17.68 q/ha) and estimated essential oil yield (26.50 kg/ha). Higher benefit cost ratio (2.14) was obtained when crop was planted in July and harvested after 2nd growing season which was followed by planted in March and harvested after 2nd growing season (1.81). In fifth experiment “Management of A. calamus under different plant spacings, organic manures and fertilizers” Treatment combination of 5t Vermicompost + NPK (100:60:40) with 20x20 cm spacing resulted in maximum estimated fresh rhizome yield (63.25 q/ha), estimated dry rhizome yield (31.63 q/ha) and estimated essential oil yield (30.24 kg/ha) whereas higher benefit cost ratio (2.32) was observed when plants were planted at 20x20 cm spacing and NPK (100:60:40 Kg/ha) was applied which was followed by 30x20 cm spacing and NPK (100:60:40) Kg/ha (1.84). | en_US |
