At each location, the experiment was laid out in randomized complete block design （RCBD） in three replications. Plot size was 9 m2. Data were collected on sprout count, plant height, number of tillers, number of leaves, main pseudo stem girth, rhizome number and weight. Analysis of variance was carried out on the combined data using GenStat Discovery Edition software. Results based on the combined data from four locations indicate that turmeric genotypes did not vary in percentage emergence and number of leaves. However, they varied in height, main pseudo stem girth, tillering, number and yield of fresh rhizomes. The effect of location on all attributes was significant （P 〈 0.05） with Jos location giving consistently the least values for all attributes thus suggesting that this location may not be suitable for the commercial production of turmeric. Genotype by environment interaction for most attributes was not significant indicating that the genotypes responded the same way across the locations. Ten genotypes, viz., UT39, UT44, UT46, UT58, UT50, UTI4, UT41, UT6, UT38 and UT35, are identified as promising and require further evaluation as pre-condition for nomination for official release to farmers.展开更多

The high potential of liquefaction is generally recognized when these types of soils are laid under the hydrostatic water table. Low plasticity silts, silty sands and sands are found as recent alluvial deposits in the western coastal part of Albania, especially in the sandy beaches of Adriatic Sea near Durres City. The aim of this study is to evaluate the soil liquefaction potential in the area of Golem. Ten CPTUs （cone penetration test with pore pressure measurements） are carried out for the site investigation of soils. In this paper, results of the CPTU based liquefaction analysis are presented. The data of two CPTUs （10 in total） are analyzed and factor of safety was found by considering different levels of hazard and ground water. The results of liquefaction potential analysis show that the soils in the area of Golem have a high risk of liquefaction.展开更多
