Online published on 10 May, 2021. Abstract Survival and growth performance of four tree species viz., Bischofia javanica, Elaeocarpus floribundus, Swietenia macrophylla and Cinnamomum zeylanicum was studied under silvihorticultural system in the model farm of the Department of Forestry, Uttar Banga Krishi Viswavidyalaya during 2016-2019. B. javanica obtained highest growth in terms of collar diameter 10-12 cm class and height (3.80 m) followed by S. macrophylla and E. floribundus with collar diameter 6-8 cm and height growth 3.50 and 2.13 m respectively and C. zeylanicum also exhibited 6-8 cm class and lowest height growth (1.5 m). The study also indicated a stability of species survival in S. macrophylla (100%), B. Javanica (98%) and E. floribundus (90%) and C. zeylanicum (37.5%) for terai region. B. javanica was the best performing species for all parameters including growth of collar diameter, height and volume increment. There is need for further investigation for nutrition management to obtain optimal growth condition. Top Keywords Collar diameter, Increment, Silvihorticultural system, Survival. Top | |
