The experiments was conducted at a farmers’ field adjacent to the HSTU Research Farm, Dinajpur during 28th April to 13th December 2018 to evaluate growth and quality of two ginger (Zingiber officinale Roscoe) varieties under different tree such as ghoraneem, litchi and mango based Agroforestry systems. The experiment was two factors RCBD where Factor A (four Agroforestry systems) and Factor B (two ginger varieties). Factor A (Agroforestry system) were- T1=under Ghoraneem, T2= under Litchi, T3= under Mango and T4= Open field (control). Again, factor B (variety) were- V1= Deshiand V2= China. Therefore, the treatment combinations were T1V1, T1V2, T2V1, T2V2, T3V1, T3V2, T4V1 and T4V2. The experiment results revealed that the growth and quality of ginger were significantly varied by the main effect of different Agroforestry systems. The highest germination speed, plant height was higher under Ghoraneem (T1) but thehighest fresh rhizome weight (21600 kg/ha) was found under Mango based System (T3), whereas the highest dry rhizome weight (20%) was found under Open field condition (T4). The main effect of varieties on growth and quality of ginger were significantly varied. Germination speed, plant height, fresh rhizome weight was higher in deshi ginger (V1) but highest dry rhizome weight was found in china ginger (V2). The interaction effect of Agroforestry systems and ginger varieties was also significant. The highest germination found in T1V1.Again, the tallest plant was recorded in T1V2.The highest fresh rhizome weight (20865 kg/ha) was found in T3V1 but the highest dry rhizome weight was found inT4V1 (21.25 %). The relationship between light intensity and fresh ginger rhizome yield was inversely proportional. The highest ginger rhizome yield (21600 kg/ha) was found when the total light intensity was 115.50 LUX under Mango (T1) and the lowest ginger rhizome yield(18366 kg/ha) was when the total light intensity was 321.50 LUX in open field (T4).
