Determining the Effect of Rooting Media and Different Polythene Wrappers on Air Layering of Grape Fruit (Citrus paradisi)

The present study aims to investigate the “EFFECT OF ROOTING MEDIA AND DIFFERENT POLYTHENE WRAPPERS ON AIR LAYERING OF GRAPE FRUIT (Citrus paradisi’)”at The Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad, during the period 2023-24. The experiment was laid in completely randomized block design with three replications and ten treatment combinations. viz, T1 (BA1000PPM + BLACK POLYTHENE + SPHAGNUM MOSS) ,T2 (IBA1000PPM + BLACK POLYTHENE + SAWDUST), T3 (IBA1000PPM + BLACK POLYTHENE + GARDEN SOIL+ SPHAGNUM MOSS),T4 (IBA1000PPM + BLACK POLYTHENE + SPHAGNUM MOSS+ SAWDUST), T5(IBA1000PPM + BLACK POLYTHENE + GARDEN SOIL+ SAWDUST), T6 (IBA1000PPM + WHITE POLYTHENE + SPHAGNUM MOSS), T7 (IBA1000PPM + WHITE POLYTHENE + SAWDUST),T8(IBA1000PPM + WHITE POLYTHENE + GARDEN SOIL + SPHAGNUMMOSS), T9(IBA1000PPM + WHITE POLYTHENE + GARDEN SOIL + SAWDUST),T10(IBA1000PPM + WHITE POLYTHENE + SPHAGNUM MOSS + SAWDUST). On the basis of present experimental findings, it is concluded that treatmentT4(IBA1000PPM + BLACK POLYTHENE + SPHAGNUM MOSS+ SAWDUST) was found to be best in terms of Number of days to root formation (initial rooting), Root length(cm), Root thickness(mm), Number of roots per layer, Survival percentage, Number of new sprouts per layered plant, Number of new leaves per layered plant and length of new shoot(cm) in Grape fruit.Whereas T9(IBA1000PPM + WHITE POLYTHENE + GARDEN SOIL + SAWDUST) was found to be least in terms of Number of days to root formation (initial rooting), Root length(cm), Survival percentage, Number of new sprouts per layered plant, Number of new leaves per layered plant and Length of new shoots(cm) whereas in Root thickness(mm) and number of roots per layer in Grape fruit.
