Determining the Effect of IBA and Rooting Media on Air Layering in Kinnow (Citrus spp)

Abstract

The present investigation was carried out in the department of Horticulture, Prayagraj, Naini Agricultural Institute, Sam Higginbottom Institute of Agriculture, Technology and sciences, Prayagraj during 2023-2024. The study aimed to determine the best treatment combination for increasing farmer profitability and yield. A Factorial Randomized Complete Block Design including twelve treatment combinations and three replications was used to set up the experiment. The treatments consist of various IBA Concentration (1000 and 1500 ppm) rooting media (Cocopeat, vermicompost and soil). Result showed that the treatmentT8(Soil+Cocopeat+IBA at 1000ppm) achieved the best growth features, including success percentage (91.67%), survival percentage (66%), number of days to root formation (initial rooting)(27.67), number of days to complete rooting(46.33),Root length(5.43),Root thickness(3.03), number of roots per layer(13.10), number of new sprouts in a layer per month(6.00,11.67,10.33,6.33),number of new leaves in a layer per month (7.67,11.33,12.6,13.6) and length of new shoot in a layer per month (7.67,11.33,12.6,13.6). The results of the study can be used to obtain the best results for propagating this plant vegetatively.
