Assessment of different bioregulators on survival and growth of black pepper cuttings (Piper nigrum L.)

Abstract

The present investigation entitled “Assessment of different bioregulators on survival and growth of black pepper cuttings (Piper nigrum L.).” was conducted at the Department of Horticulture, College of Horticulture Dapoli, Dist. Ratnagiri during the year 2020-2021. The experiment was conducted in Randomized Block Design (RBD) with seven treatments and three replications. The treatments were T1 – Vermiwash 15%, T2 – Vermiwash 20%, T3 – Vermiwash 25%, T4 – Cattle urine 5%, T5 - Cattle urine 7.5%, T6 - Cattle urine10%, T7 – Control(no drenching). Growth parameters of black pepper cuttings viz. number of days required for initiation of sprouting, number of days required for peak sprouting, number of days required for complete sprouting, length of the shoot, number of leaves, leaf area, girth of sprout, vine length, intermodal length, number of primary roots, root length, number of nodes, dry shoot weight, dry root weight, absolute growth rate, relative growth rate were significantly influenced by bioregulators drenching. In treatment T2 (Vermiwash 20%) high survival per cent (82.67%), less days required for initiation of sprouting (20.67).
