Effect of position of branch on tree, season and treatment with NAA was studied on rooting cuttings of a 40 years old tree of Tectona grandis Linn. f. growing in the New Forest environment. The treatment of NAA showed significant promotive effect on per cent callusing, rooting, sprouting, number of shoot and root per cutting and root length while, the effect of position was only significant for per cent rooting and sprouting. The effect of season (month of planting) was significant for all parameters that is per cent callusing, rooting, sprouting, number of shoot, leaves, root per cutting, shoot length and root length. The two and three factor interaction effects were non-significant for all the parameters. Maximum per cent callusing occurred in June. It was totally absent in the month of October and November; even NAA application did not cause callusing in these months. Maximum per cent rooting was recorded in August and minimum in November, while maximum sprouting was recorded in June and minimum in November. Number of shoot and leaves per cuttings were maximum in July and minimum in November while, the number of roots per cutting was maximum in June and minimum in November. Cuttings obtained from lower position showed the highest percentage of sprouting and rooting.
