Performance of Tecomella undulata (Desert Teak) Stump Planting Over Seedling for Growth and Straightness under Arid Condition

Abstract

Tecomella undulata (Rohida) stump planting and seedlings had shown 100 percent survival during the study period. Stump plants exhibited enhance growth parameters over seedling originated plants. Treatment T4 showed best growth performance in terms of plants’ height, collar diameter, number of leaves and sprout density, with 44% and 54% higher growth in height and collar diameter than seedlings after two years of planting. As per the modified visual method of assessing straightness, higher stem straightness was obtained in T4 (0.56m) and T3 (0.40m) which had 77% and 66 % stem straightness, and score of 6 & 5 which plunge under A grade category. Whereas, T2 and T1 (0.33m & 0.23m) had 48 and 32% stem straightness percent with a score of 4, 3 and 2, which comes under B & C grades. From the study it was a clearly found that stump plantings treatment T4-(>8-9mm thickness (pen/pencil-sized), with 20-25cm stump plants (2-5cm stem and 15-20cm tap root) was found to have achieved enhanced growth compared to seedling plants.
