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 the growth and yield of ginger. Healthy and disease free ginger rhizomes were select 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 with Twelve treatments replication thrice. 180 days after sowing that variety V₁ (Baruwa Sagar, 57.54 and 58.09 cm) maximum height than the variety V₂ (Rio-de-Janeiro, 56.17 and 56.34 cm.) in both the years that the data also showed that the application of urea as foliar spray increase the plant height. Significantly both years. In respect of doses of NAA, 400 PPM was (N₂) height of 59.69 and 59.81 cm. both the years and next dose of 200 PPM (N₁) maximum height 57.11 and 57.84 cm. as compared to 53.75 and 54.01 cm. in N0 in both year. Thickness of main stem at 180 days that variety V1 (Baruwa Sagar, 0.895, 0.896 and 0.895 cm.) was superior to variety V₂ (Rio-de-Janeiro, 0.881, 0.864 and 0.872 cm.) in respect of thickness in first year, second year and in pooled mean. It was also found application of urea in both the years and pooled analysis. It was further observed that there was maximum thickness in N₂ (NAA 400 PPM, 0911 cm) which was at Par with N₁ (NAA 200 PPM, 0.901 cm.) and minimum in No (NAA OPPM, 0.852 cm.) in the first year however, in the second year. Number of tillers at 180 days that the variety V₁ Baruwa Sagar as 13.62, 13.18 and 13.40 was superior than variety V₂ Rio-de-Janerio recording 13.17, 12.93 and 13.04 Number per plant in the first and second year and in pooled analysis, respectively. it was also found application of Urea in both the years. The data furthe showed that treatment N₂ (NAA 400 PPM) produced maximum number of tillers an 13.78 per plant, which was as good as to N₁ (NAA 200 PPM) recording 13.40 number of tillers per plant in the first year. However, in the second year N₂ was significantly superior by showing 13.82 number of tillers as compared to 13.40 and 11.95 per plant in N₁ and N₀, respectively. Yield per Plant of ginger that the variety V₁ (Baruwa Sagar) was significantly superior to variety V2 (Rio-de-Janeiro) in both the years and in pooled analysis. The data showed that there was maximum plant yield with the application of N₂ (NAA 400 PPM) followed by N₁ (NAA 200 PPM) and minimum in N₀ (NAA O PPM) in both the years as well as in pooled mean. The maximum value was 151.97 gm. in the first year in N₂, 149.67 gm. in the second year and 150.82 gm per plant in the pooled mean. Similarly, the application of Urea 2 per cent also produced the higher yield to the tune of 150.68, 148.20 and 149.44 gm. per plant respectively in the first year, second year and in pooled mean. Yield per hectare that variety V₁ (Baruwa Sagar) sagar significantly superior to variety variety V₂ (Rio-de-Janerio) in both the years as well as pooled mean. That yield values were 286.02, 277.32, 281.66 q/ha in first year second year and pooled mean, respectively. The application of urea also showed significantly increase in yield in both the years as well as in pooled mean. Similarly, the N₂ (NAA 400 PPM) gave the maximum followed by N₁¬ (NAA 200 PPM) and N0 (NAA O PPM) to the tune of 301.39, 299.03 and 300.21, 287.36, 284.03 and 265.69 and 235.56, 244.03 and 258.42 q/ha in first year second year and pooled mean respectively.
