Title : Integrated approaches for management of spot blotch of wheat [Bipolaris sorokiniana (Sacc. In Borok) Shoem] and its effect on crop growth and yield

Abstract :

Integration of soil application, seed treatment and foliar spray with fungicide i.e. propiconazole provided protection of spot blotch and increased crop growth and yield of wheat. Among the treatment, the maximum germination with 99.65 % and vigour index with 795.20 was recorded in T3 treatment as seed treatment with bioformulation of T. viride @ 4 % + soil application with vermicompost (1:4) + foliar spray of propiconazole @ 0.1 %). The minimum disease area and disease severity was also recorded in T3 (Seed treatment with bioformulation of T. viride @ 4 % + soil application with vermicompost (1:4) + foliar spray of propiconazole @ 0.1%), representing value as 0.46 cm2 and 10.72 % respectively which was followed by T6 (Seed treatment with bioformulation of T. viride @ 4 % + soil application with mushroom compost (1:4) + foliar spray of propiconazole @ 0.1 %) as 0.52 cm2 and 12.65 %, respectively. The growth promoting effect of wheat crop have also been perceived from integrated approaches. The maximum with 40.15 and 27.40 cm shoot and root length were found in T3 treatment (Seed treatment with bioformulation of T. viride @ 4 % + soil application with vermicompost (1:4) + foliar spray of propiconazole @ 0.1 %). The highest grain yield with 39.01g was also obtained in T3 (Seed treatment with bioformulation of T. viride @ 4 % + soil application with vermicompost (1:4) + foliar spray of propiconazole @ 0.1 %), representing 80.43 per cent increased over control.
