Effect of Methods and Timings of Vegetative Propagation in Aonla (Emblica officinalis Gaertn.) under the Northeastern Region of Uttar Pradesh, India

Abstract

Vegetative propagation enables large-scale multiplication of plants using suitable propagation techniques, as it produces true-to-type plants and ensures early fruit bearing. Among the vegetative methods, budding and grafting are commonly practiced in aonla. The present experiment was undertaken to standardize suitable propagation methods and optimal propagation times for aonla in the northeastern region of Uttar Pradesh, India. The investigation was conducted during the year 2024-25 at the Experimental Unit of the Department of Horticulture, Tilak Dhari Post Graduate College, Jaunpur, Uttar Pradesh. The experiment was undertaken to determine the most suitable time and method of vegetative propagation for aonla (Emblica officinalis Gaertn.). The study comprised six propagation dates at fortnightly intervals from July to September, namely 1 July, 16 July, 1 August, 16 August, 1 September, and 16 September. Two methods of vegetative propagation, viz., wedge grafting and patch budding, were evaluated during the course of the investigation. The results of the study revealed that among the propagation methods, wedge grafting produced the best results compared to patch budding. It recorded the minimum number of days to bud sprouting (13.43 days), the highest bud take percentage (87.19%), total number of leaves (27.90), sprout length (15.85 cm), and survival percentage (82.46%). Among the different propagation dates, 16 August proved to be the most suitable time, recording superior performance in terms of bud/graft sprouting, sprout length, and survival percentage.
