Abstract:
Ginger alloramin is an important condiment in food and pharmaceutical industries because of its antioxidant and poly phenolic compounds. Therefore present investigations are based on the study of the effect of foliar spray of urea and NAA on the recovery percentage and Production of olioresin. Study was conducted in the department of Horticulture at Kulbhaskar Ashram P.G. College, Allahabad during 2016-17. Recovery percentage of oleoresin calculated on variety Rio-de-Janeiro (5.76, 5.62 and 5.69 per cent recovery of oleoresin) was more than Barua Sagar (5.43, 5.33 and 5.38 per cent) in the first year as well as second year in pooled analysis. The recovery of oleoresin content was also more in U1 (Urea 2%) and found 5.83, 5.63 and 5.73 per cent in both the year and pooled mean. In case of NAA application, the maximum Oleoresin content was found in N2 followed by N1 and No. The values were 6.16, 5.70 and 4.93; 6.03, 5.61 and 4.79 and 6.09, 5.65 and 4.86 percent, respectively in first year and second year and in pooled mean. The production of oleoresin is the important character to judge the effect of Urea and NAA on the varieties under observation. Production of oleoresin was more in variety Rio-de-Janeiro to the tune of 373.15, 357.14 and 365.25 Kg/ha than in variety Baruwa sagar which contributed 342.67, 326.06 and 334.36 Kg/ha. in first year, second year and pooled mean respectively. The application of Urea also increased the production of oleoresin as 372.72, 350.80 and 361.76 kg/ha in first year, second year and pooled mean, respectively. it was also noticed that the maximum oleoresin content was obtained with the application of N2 (NAA 400 PPM) followed by N1 (NAA 200 PPM) and No (NAA OPPm) to the extent of 395.79, 379.27 and 387.53, 362.72, 348.78 and 355.75 and 315.22, 297.05 and 306.13 Kg/ha, respectively in first year, second year and pooled mean.
