EFFECT OF DIFFERENT GROWING CONDITIONS AND VARIOUS CONCENTRATIONS OF IBA ON THE ROOTING AND SHOOTING OF HARDWOOD CUTTING OF PHALSA (GREWIA ASETICA L.) UNDER VALLEY CONDITION OF GARHWAL HIMALAYAS

The effect of different growing conditions and various concentrations of IBA on the rooting and shooting of hardwood cutting of phalsa (Grewia asetica L.) under valley condition of Garhwal Himalayas was assessed in an experiment conducted at the Horticulture Research Centre, Chauras Campus. H.N.B. Garhwal University, Srinagar, Garhwal (Uttarakhand), India. The experiment was laid out in Factorial Randomized Block Design (RBD) with three replications. For preparing the rooting media, sandy soil and farm yard manure (FYM) in ratio of 2:1 by v/v were mixed thoroughly, cleaned for stones and grasses, then the mixture was filled in root trainers. Properly prepared cuttings of about 15-20 cm length in the month of September were treated with different concentrations of IBA viz., 1000, 1500, 2000 ppm and control for 10 second by concentrated solution dip method and planted in 2 different conditions namely shade house and mist chamber. The mist house growing condition was found effective in increasing the success rate of the cuttings. The cuttings treated with IBA 2000 ppm, performed the best in all aspects, as rooting percentage, survival percentage, length of shoot, length of root, thickening of root and leaf sprouting in shoot. Overall treatment G 2 C 3 (Mist chamber with 2000 ppm IBA) treatment combination was found best in all parameters taken.
