Use of different levels of plant growth regulators on rooting of cutting in fig (Ficus carica L.)

The experiment was carried out at Central Nursery, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. during kharif season in year 2018-19, on fig variety Dinkar in a randomized block design with three replications and twelve treatment combinations. The objective was to study the effect of different levels of plant growth regulators on rooting of cutting in fig. The experiment was laid out in Randomized Block Design in Twelve treatments with three replications. The treatments were T1 (IBA-1000 ppm), T2 (IBA-2000 ppm), T3 (IBA-3000 ppm), T4 (IBA-4000 ppm), T5 (NAA-1000 ppm), T6 (NAA-2000 ppm), T7 (NAA-3000 ppm), T8 (NAA-4000 ppm), T9 (IBA 1500 ppm + NAA 1500 ppm), T10 (IBA 2500 ppm + NAA 2500 ppm), T11 (IBA 3500 ppm + NAA 3500 ppm) and T12 Control. The study found that IBA at 4000 ppm was the most effective growth regulator for enhancing root growth in fig cuttings. It significantly reduced the time required for rooting, increased rooting percentage, and produced the longest roots, highest fresh and dry root weights, and maximum number of roots at both 60 and 90 days. While combinations of IBA and NAA also showed positive effects, IBA at 4000 ppm outperformed all other treatments. The control group consistently had the lowest results across all measured parameters.
