The study was undertaken to refine nursery production technology on aonla in order to maximize nursery output. Healthy seedlings of aonla cultivars NA-10 and NA-7 were transplanted at three spacing and were applied three fertilizer doses. In Another experiment the seedlings were transplanted on five (15 th and 30 th June, 15 th and 30 th July and 15 th August) dates to find out the optimum time for transplanting of aonla rootstock. It was also observed during the study that the seedling survival and plant growth in spacing S 1 (30×30 cm 2) were low as compared to other spacing, which resulted in poor budding success and ultimately lesser number of saleable plant. In spacing S 3 (30×10 cm 2) the initial plant population was very low, although, the seedling survival, growth parameters and budding success were highest in combination having S 3 spacing, final production of saleable plants was lower than spacing S 2 (30×20 cm 2). There was a definite effect of budding time on budding success. The seedlings budded in July had better bud taken as compared to those budded in March. However, the seedlings transplanted on 15 th July observed to have the maximum budding success both during March and July. The rate of successful budding increased steadily up to third transplanting date (15 th July) and declined thereafter. Aonla cultivar NA-10 had better budding success (52.87%) in the plants budded in March whereas the effect was non-significant during July. 2. Materials and Methods An experiment was conducted to work out optimum spacing and fertilizer level for rapid nursery production of aonla on the experimental farm of Institute of Biotechnology and Aonla, Emblica officinalis, budding, nursery, fertilization
