YIELD AND QUALITY OF DIFFERENT TURNIP VARIETIES INFLUENCED BY VERMICOMPOST

Abstract

An experiment was carried out at the Horticulture research field of Sher-e-Bangla Agricultural University, Dhaka during the period from November 2020 to March 2021 to find out the yield and quality of different turnip varieties influenced by vermicompost. The experiment was laid out in two factorial RCBD with 3 (three) replications. Factor A (Three different turnip varieties) viz. V 1 = Purple Top White Globe; V 2 = Pusa Chandrima; V 3 = Early Milan Red Top and Factor B (Four different levels of vermicompost) viz. F 1 = 0 t/ha; F 2 = 2 t/ha VC doses, F 3 = 4 t/ha VC doses and F 4 = 6 t/ha VC doses. Significant variation was found in all parameter due to the effect of different turnip variety and different amount of vermicompost application. In case of different variety, the maximum yield (17.84 t ha -1 ) was recorded from the Purple Top White Globe (V 1 ) as it is a high yielding variety. One the other hand, the lowest root yield (11.02 t ha -1 ) was recorded from Pusa Chandrima (V 2 ) which is a moderate early variety. In case of different levels of vermicompost, results exposed that the highest roots yield (17.22 t ha -1 ) was recorded from F 3 (4 t ha -1 VC) which was statistically different from all other treatments, where the lowest yield (10.75 t ha ) was achieved from F 1 (0 t ha -1 VC i.e. control). Finally, root yield as t ha -1 was the output of different varietal treatments applied as well as the effect of different level of vermicompost (VC) doses. The maximum roots yield (21.24 t ha -1 ) was found from V 1 F 3 (Purple Top White Globe with 4 t/ha VC doses) which was statistically different from others. Again, the minimum roots yield (7.80 t ha -1 ) was observed from V 2 (Pusa Chandrima with 0 t/ha VC doses i.e. Control) which was statistically similar with V 2 (Pusa Chandrima with 2 t/ha VC doses). The findings of the present investigation clearly indicates that the use of Purple Top White Globe turnip variety and optimum level of vermicompost for growing turnip root is a viable option for improved cultivation.
