The experiment was conducted at six locations, Spices Research Centre, Bogra (L1); Spices Research Sub-Center, Lalmonirhat (L2);Regional Spices Research Centre, Comilla (L3); Joydebpur (L4), Magura (L5) and Spices Research Sub-Center, Faridpur (L6)) during April, 2011 to February, 2012. Three turmeric lines viz., T098, T0106 and T0110 were included in this study with BARI Halud-3 as check. The experiment was laid out in RCB design with three replications in each location. The unit plot size was 4.0m × 1.8m. cm. Mother rhizomes of 35-45 gm were used as planting material. Planting was done April, 2011 maintaining 60cm × 25cm spacing. The land was fertilized with cowdung, N, P, K, S and Zn at the rate of 10t, 100, 36, 85, 20 and 2.0 kg per hectare, respectively. The entire quantity of cowdung, P, S, Zn and half of K were applied as basal dose. Half of N was applied at 50 days after planting. Remaining N and K was applied as top dress in two equal splits at 80 and 120 days after planting. Weeding and other intercultural operations were done as and when necessary. The crop was harvested on February, 2012 when all the plants started drying. Data on yield and yield contributing characters were analyzed statistically and the means were compared by LSD method.
The line × location effect of rhizome yield (t/ha) varied significantly. The results indicated that T0106 gave the highest yield across the locations except Faridpur. T0110 gave the highest yield at Faridpur.
The core color of rhizome was recorded deep orange yellow in all tested lines and exhibited moderate tolerance to leaf blight disease at all six locations. In terms of preference, high yielding line with maximum dry matter and attractive yellow color is considered for final selection.
