Abstract
The present investigation entitled “Standardisation of nursery techniques for better outplanting performance in aonla (Emblica officinalis Gaertn.)” was undertaken in the Department of Silviculture and Agroforestry, Dr.Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan- 173230 (HP) during 2013-2014. The study involved two nursery experiments and one outplanting experiment, each laid out in randomized block design (factorial), replicated thrice, to standardize best growing medium and container type and to determine best shoot and root pruning levels to compare the transplanting performance in the nursery. During the present investigation, it has been revealed that seedlings raised in polybag of size 9”x4.5” with eight side + eight bottom perforations and use of growing medium consisting of soil + sand + mushroom compost in ratio of 1:1:2 recorded significantly highest germination (76.00%), growth and biomass production in the seedlings. Furthermore, the seedlings raised in this way resulted in superior outplanting survival (93.33%), final height (63.13cm) and collar diameter (7.62mm) growth in the field. Similarly, the use of shoot pruning at 10cm and root pruning at 13cm level during the month of August resulted in significantly highest transplanting survival(83.33%), growth and biomass production in the plants at the end of eighth month and therefore proved to be the best treatment for raising quality planting stock in the species.
