Fig (Ficus carica L.) is a nutritious fruit packed in with a rich source of calcium, iron and sugar. For this, there is an increased awareness among farmers to cultivate fig. Hence the present investigation was carried out in the fig block of orchard of Department of Horticulture, Khalsa College, Amritsar during the year 2019-2020 to study the effect of etiolation and growth regulators on the rooting of air layers in fig cv. Brown Turkey. The research study was carried out with two levels of etiolation (etiolation and non-etiolation), three levels of NAA(500, 750 and 1000 ppm) and IBA( 500.750 and 1000ppm) along with control to find out the influence of etiolation, growth regulators and their treatment combinations. In the experiment the treatments were replicated thrice in a factorial randomized block design. The results of the study revealed that etiolation(E1) proved to be the best in minimising the number of days to initiation and 100 percent rooting. It was also superior in increasing the production of primary and secondary roots, root length and thickness, rooting percentage and survival of rooted air layers. Among growth regulators the air layered shoots treated with 1000 ppm IBA was significant than other auxin treatments in terms of minimizing the time for root initiation , increase in rooting percent, primary and secondary shoot formation, length and thickness of roots, early sprouting with higher number of sprouts per cutting, greater shoot length with more number of leaves. Among interaction effect between etiolation and application of growth regulators the treatment combination E1T5 was numerically effective in reducing the period for first rooting, rooting percentage, increase in number, length and weight and primary and secondary roots, shoot number and shootlength with maximum survival of the air layers.
