Effects of Plant Growth Regulators (IBA) and Soil Media on Success, Growth and Survival of Stem Cutting of Assam Lemon (Citrus lemon (L) Burm)

An investigation was carried out to study of the “ Effects of plant growth regulators (IBA) and soil media on success, growth and survival on rooting of stem cutting in Assam Lemon (Citrus lemon (L) Burm).” was successfully carried out in the year 2021-2022 in naturally polyhouse of experimental farm ,under (KVK),Central Agriculture University, Selesih, Aizawl, Mizoram. The experiment was carried out using Factorial Completely Randomized Design (FCRD) with replicated thrice. The cuttings were treated with five different doses of IBA and four different soil media and then planted in raised bed polyhouse. From the experiment, T5M2 (IBA 800ppm+Soil + Sand + vermicompost + Cocopeat (1:1:1:1)) was the best treatment in all the parameters for rooting of stem cutting in Assam lemon and over all the treatment gave the significant response in respect to all the parameters i.e. Date to first new leaf initiation (16.33), Number of leaf per plant (13.50), Plant height (21.43 cm), Shoot length (6.59 cm) , Stem diameter(2.37 cm) , Number of branches (6.08), Length of tap root (7.92 cm), Root spread (8.42 cm), Fresh weight of root (0.54 g), Dry weight of root(0.34 g), Survival percentage of cuttings (1.00), during the observation period in the foot hills of Mizoram.
