| dc.description.abstract | An experiment was conducted in the research field of the Department of Agroforestry and
Environment, Hajee Mohammad Danesh Science and Technology University, Dinajpur
during 24 March 2018 to 10 January 2019, in order to investigate the growth and quality of
different turmeric varieties under mango tree and open control. The experiment was
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; another 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 Randomized Complete Block Design
with Three replications. Findings of the study revealed that growth and quality of turmeric
significantly varied in the main effect of different agroforestry production systems. The
tallest plant height, length and width of leaf were recorded in (T1) and lowest were found in
(T2). The maximum number of finger, length of the biggest rhizome and width of the biggest
rhizome were recorded in (T2), and minimum were found in (T1). The highest fresh weight of
rhizome 11000 kg/ha was obtained in (T2) and lowest 7055 kg/ha in (T1). And the highest
dry weight of rhizome 2126 kg/ha was found in (T2) and lowest 1456 kg/ha was observed in
(T1).The highest light intensity was 68.96 LUX observed in (T2) and lowest 34.70 LUX in
(T1). Moreover, the highest germination speed was found in (T1) and lowest in (T2).The
experimental results revealed that the main effect of varieties on growth and quality
contributing characters of turmeric were significantly varied with each other. The tallest
plant height, length of leaf, width of leaf, number of finger, length and width of the biggest
rhizome with (V2) were recorded. 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). Germination speed was found highest with (V2) and lowest with (V1).The
interaction effect of different turmeric variety and production systems on the growth of
turmeric was found significantly different at different days after planting (DAP). The longest
plant height was recorded with T1V3 but maximum biggest rhizomes lengths were with T1V1
and maximum biggest rhizome width was found T2V2. The highest fresh rhizome weight
13611 kg/ha and dry rhizome weight 2631 kg/ha were recorded in (T2V2) and (T2V2)
respectively, on the other hand the lowest were found in T1V2 (5944 kg/ha) and T1V2 (1208
kg/ha). Highest germination speed was found in T1V3 and lowest in T1V1. | en_US |
