abstract
An experiment was carried out during the year of 2009 - 2012 at lava (2040 m asl), Darjeeling hill, under the aegis of Uttar Banga Krishi Viswavidyalaya, to evaluate the effect of various showing measures and organic nutrient application on newly introduced plant Coptis teeta in Darjeeling hill. Seedlings were planted in main field, to work out its morphology and other growth pattern with agronomic manipulation. Field experiment was conducted in split plot design with three replication, having four method of sowing in main plot, which includes viz. plain bed, sloppy land (terrace), furrow and undulated sowing, and four nutrient management practices in subplot viz. vermicompost (@0.50t/ha), FYM (@0 50 t/ha), leaf manure (@0 50 t/ha) and control (no nutrient). This is a small herb of 20-25 cm in hight. This has compound leaf, serrated into 3 part leaf blade ovate, triangular in shape. Root was fibrous in nature with small yellow coloured. Colour of the rhizome was golden yellow. Inflorescence includes 3-5 flowers, bract elliptic, 3 parted or pinnately divided, solitary, cymose. Rhizome weight was more found with sloppy land cultivation (3.51 g), and was at par with the ridge method of planting (2.96 g), and statistically better to rest of the imposed treatments of main plot. This treatment gave 85.75 and 56.61% more yield of rhizome compared to plain bed sowing, which gave least weight amongst all the observations under main plot. Root length was more observed with the sloppy land showing and statistically better to rest of the treatments. Rhizome weight was more found with vermicompost (@0.50t/ha), and was at par with leaf manure (@ 0.50 t/ha) and statistically better to other set of organic nutrient management. This treatment gave 102.31 and 82.11%, more rhizomes compared to control, respectively. Root length was more observed with the vermicompost (@0.50t/ha) and was statistically similar with the FYM (@0 50 t/ha). From the study, it can be conclude that sloppy land with vermicompost (@0.50t/ha), become more preferable condition for good growth of rhizome and root of Coptis teeta, which has high demand in domestic and international market.
