Abstract
The present investigation entitled “Effect of plant growth regulators on rooting growth
and survival of semi-hardwood cutting in Pomegranate (Punica granatum L.) cv Bhagwa”
was conducted at Fruits nursery, Department of Fruit Science, college of Horticulture, Banda
University of Agriculture & Technology, Banda - 210001 (U. P.) during the year 2020-21. The
experiment was laid out in a Randomized Block Design with 9 treatments and 3 replications. The
minimum number of days taken to first sprouting (10.26 days). The average total sprouted cuttings
(89.30%) diameter of shoot (6.75 mm), shoot length of cutting (24.70 cm) at 90 DAP, number of
leaves per cutting (5.66, 6.80, 9.96) at 30,60,90 DAP respectively, fresh weight of shoot (11.19 g)
and dry weight of shoot (5.47 g) at 90 DAP was recorded in treatment T4- IBA 1000 ppm. The
maximum rooting percentage of cutting (84.32) at 90 DAP respectively. The length of root of
cutting (10.80 cm, 18.16 cm, 27.15 cm), average number of roots per cutting (20.19, 24.53, 37.52)
at 30, 60 and 90, DAP respectively. The fresh weight of root (1.39 g), dry weight of root (0.76 g),
survival percentage of cutting (90.54 %) at 90 DAP respectively was recorded under the treatment
IBA- 1000 ppm. Therefore, it is concluded that the application of IBA-1000 ppm shows the best
result for all parameters like, days taken to first sprouting, total sprouted cutting, shoot diameter
and length, numbers of leaves par cutting, fresh and dry weight of shoot, rooting percentage of
cutting, length of roots, fresh and dry weight of roots, survival percentage of cutting and number of
roots per cutting.
This research has been recognized as practical application by nursery man of pomegranate
for preparation of better quality planting materials along with better survivability. The work has
both academic as well as practical significance and it will help to farmers for establishment of
pomegranate nursery resulting in generate the farmer’s income.
