Growth and Yield of Three Turmeric Varities (Curcuma longa L.) under Mango Based Agroforestry

An experiment was conducted at the Department of Agroforestry and Environment, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh during 24 March 2018 to 10 January 2019, to investigate the growth and yield of different turmeric varieties under mango trees and open control. The experiment consisted of two factors with three replications. Among the two factors, one factor was two production systems: T1 =Mango + Turmeric and T2=Open control + Turmeric; the second factor was three turmeric local varieties: V1=Thailand, V2= Malshira and V3= Debipat. Interaction treatments between factor A and factor B were T1V1, T1V2, T1V3, T2V1, T2V2 and T2V3 combinations. The experiment was laid out following a Randomized Complete Block Design with three replications. Findings of the study revealed that growth and yield of turmeric significantly varied in the main effect of different agroforestry production systems. The highest fresh weight of rhizome (11000 kg/ha) was obtained in T2 and lowest (7055 kg/ha) in T1. The highest dry weight of rhizome (2126 kg/ha) was found in T2 and lowest (1456 kg/ha) was in T1. On the other hand the highest fresh weight of rhizome was 9777 kg/ha found with (V2) and lowest 8055 kg/ha with (V3), the highest dry weight of rhizome was 2013kg/ha found in V1.In case of interaction, the highest fresh rhizome weight (13611 kg/ha) and dry rhizome weight (2631 kg/ha) were recorded in T2V2 and T2V2, respectively. However, the lowest were found in T1V2 (5944 kg/ha) and T1V2 (1208 kg/ha).
