Influence of Vermiwash and Plant growth regulators on the Exomorphological characters of Abelmoschus esculentus (Linn.) Moench

Abstract

3 Abstract: The role of vermiwash, an organic liquid fertilizer as foliar spray on plant growth and its impact in comparison with the plant growth regulators on the exo-morphological characters of Abelmoschus esculentus were investigated. The results of the study showed that vermiwash exhibited growth promoting effects on the exo-morphological characters such as plant height, length and diameter of the internode, number of leaves, leaf surface area, root length, wet and dry weight of the shoot and root of Abelmoschus esculentus. Among the various foliar treatments used in the study, 15% vermiwash (V-II) showed growth enhancing effects followed by 10% vermiwash (V-I), Gibberelic acid (100 g/ml) and Naphthalene acetic acid (100 g/ml). Maximum root length and plant biomass was recorded in V-II. These results clearly indicate that vermiwash can be exploited as a potent biofertiliser and foliar spray.
