Abstract:
A field study was conducted at Department of Horticulture Kulbhaskar Ashram P.G. College, Allahabad during 2016 and 2017 to study the Effect of foliar spray of urea and NAA on Rhizome rot of Ginger. Healthy and disease free ginger rhizomes were selected and used for planting. The rhizomes were then cut into small pieces of about 15 gm. weights and planted at spacing of 25x20 cm. The experimental was conducted in Factorial Randomized Block Design. Results showed that the incidence of rhizome rot disease during the crop period indicated that main effect of urea and NAA and their interaction differed significantly in both years. It could be inferred from the mean table of urea and NAA that the application of Urea 2.0% decreased the infection of total rhizome rot in both the years. In case of NAA the maximum infection percent (13.21 and 13.37) was found in N₂ (NAA 400 ppm) followed by N₁ (NAA 200 ppm) 11.12 and 11.32 percent which was at par with No (NAA 0 ppm) 10.55 and 10.68 percent in first and second year respectively. The minimum infection of total rhizome rot was found in V₁ x N₁ which was at par with U₁ x V_o followed by the treatment combination V₁ N₂ whereas the maximum infection was found in U_oN₁, which was at par with U_oN₂ in both the year.
