Abstract
This experiment was conducted to evaluate the best treatment combination among IBA, Seaweed Extract and Phloroglucinol concentration for assesing the success rate, survival percentage of Kinnow. The experiment was laid out in Randomized Design having 12 treatments and replicated 3 times. The T7 IBA@2000ppm+Phloroglucinol@5000ppm recorded highest values in terms of success in rooting percentage (73.67), number of days taken for initial root formation (28.44), root length of layers (7.30cm), number of roots per layering (20.44), root thickness (3.70mm), number of new sprouts per layer (6.56-1MAP, 8.89-2MAP, 8.56-3MAP & 8.00-4MAP), number of new leaves per layer (6.67-1MAP, 10.56-2MAP, 7.09-3MAP & 12.78-4MAP), length of new shoots (4.26cm-1MAP, 5.23cm-2MAP, 7.09cm-3MAP & 9.94cm-4MAP) and survival percentage of rooted polybag transplanted air layers (68.66%) respectively in Kinnow, whereas minimum values were recorded in T6 (IBA@3000ppm + SWE@5000ppm).
