Abstract
The present investigation was conducted at College of Forestry (ACHF), Navsari Agricultural University, Navsari, Gujarat, India. The experiment was laid out in a Completely Randomized Design with three repetitions. The cuttings were raised by using IBA @ 25 ppm + NAA @ 25 ppm. After two months of planting of cuttings the rooted cuttings which exhibited uniform growth were treated with different eight treatments of biofertilizers viz., Azospirillum, Phosphobacterium, Azotobacter and their combinations along with three repetitions were studied for six months. The treatment T : 8 Azospirillum + Phosphobacterium + Azotobacter (3.33 ml each/rooted cutting) enhanced shoot length (12.48, 18.89, 24.94, 31.80, 38.65 and 44.97 cm) and collar diameter (3.00, 4.22, 6.36 8.50, 10.29 and 11.23 mm) respectively of new sprouted shoot at 30, 60, 90, 120, 150 and 180 days after transplanting (DAT). The same treatment also recorded maximum values of fresh and dry weight of root (5.62 and 2.58 g plant-1), shoot (51.54 and 18.42 g plant-1) and plant (57.16 and 21.00 g plant-1), respectively at 180 DAT. Moreover, minimum values of above all parameters were noticed in Control. However, at 180 DAT the highest value of root: shoot ratio on dry weight basis was observed in Control (0.26).
