Abstract:
A field experiment was conducted at College of Horticulture, Mojerla during Rabi 2016-17 to study the influence of plant growth regulators and their time of application on growth and tuber yield of sweet potato Cv. Kiran. The treatment comprised six plant growth regulators viz... Cycocel, Paclobutrazole, ALAR, Salicylic acid, Gibberellic acid and Ethrel each with two different concentrations and control (water) were used as foliar spray at 30 and 45 days after planting. Experiment was carried out under factorial randomized block design (FRDB) with two replications. The result revealed that, among different plant growth regulator treatments, CCC 500 ppm recorded significantly maximum carbohydrate percentage (27.05) and protein percentage (2.33) as compared to other treatments.
