Abstract
Rooting trials were carried out using branch cuttings obtained from 7 year old plants of Acacia nilotica with four different auxins in three different concentrations replicated under different shade house environments, open condition and polytunnels. IBA was found to be most effective with 40 per cent rooting in cuttings made in the month of September. November planted cuttings failed to root even with application of auxins. Using heat and fungicide treated, soil, mixed with charred paddy husk rooting percentage improved. A polyglobule system was tried in which the cuttings were placed inside the large polythene bag and the mouth of the polythene bag tightly tied. Rooting response in such a system improved. Rooting occurred between 15th to 20th day. The system also does not require watering for over 25 days.
