Fifteen turmeric accessions were evaluated during the rainy season of 2012 and 2013 at Igbariam (6.4°N, 6.93°E) in order to identify and select high yielding genotypes suitable for production in derived savanna zone of Nigeria. The accessions were laid out in randomized complete block design (RCBD) in three replications. Results obtained indicate that plant emergence was generally high ranging from 85 – 100%. Girth of main stem, plant height, tillering, number of leaves and leaf area increased with time and there were significant differences between turmeric accessions in these attributes at most sampling dates. Number of mother rhizome ranged from 23.7 in UT39 to 34.2 in UT35; while number of primary rhizome ranged from 64.7 in UT39 to 98.4 in UT35, number of secondary rhizome ranged from 189 in UT41 to 364.4 in UT25. The mean number of mother rhizome produced in 2012 was significantly higher than the number produced in 2013 but the mean number of primary and secondary rhizome produced in both years did not differ. The weight of mother and secondary rhizome sand total rhizome yield varied significantly with accession ranging from 0.55kg/m2 in UT60 to 1.45 kg/m2 inUT41; 0.85 kg/m2 in UT16 to 1.50 kg/m2 in UT39; and 2.15 kg/m2 in UT16 to 4.15 kg/m2 in UT39 respectively. UT39 with the highest total rhizome yield did not differ from 10 other accessions in this attribute. In general, high total rhizome yield (2.15 – 4.15kg/m2) and the large numbers of secondary rhizome recorded are indicative of the suitability of derived savanna agro-ecology for commercial production of turmeric in Nigeria; however, further study is suggested to cover more locations.
