The present investigation entitled “Effect of different concentrations of vermiwash on survival and root growth of black pepper cuttings (Piper nigrum L.)” was conducted at the Department of Horticulture, College of Agriculture Dapoli, and Dist. Ratnagiri during the year 2018-2019. The experiment was conducted in Randomized Block Design (RBD) with six treatments and four replications. The treatments were T1-Vermiwash 10 % drenching, T2-Vermiwash 20 % drenching, T3-Vermiwash 30 % drenching, T4-Vermiwash 40 % drenching, T5-Vermiwash 50 % drenching and T6-Control (no drenching of vermiwash).

It is observed that root growth parameters were significantly influenced by vermiwash drenching as compare to control (i.e.) no drenching. In treatment T4 (i.e. 40% vermiwash drenching) high survival (88.50%), root length (20.37 cm), more number of primary roots (21.20), and dry root weight (2.014 g) was observed. Lowest survival (60.50 %), lowest root length (17.97 cm), lowest number of primary roots (14.15), and low dry root weight (0.710 g) was observed in control i.e. no vermiwash drenching. The vermiwash drenching at various concentrations improves the survival and root growth of black pepper cuttings in comparison to control i.e. no vermiwash drenching.
