... so highly grain trade connected to the currently independent South Sudan, where the State provides South Sudan with its whole consumption requirements from sorghum and millet. Descriptive statistic and regression analysis were used throughout the course of the study. The model of analysis used was based on Koaster [1], Correlation coefficient matrix. Regression equation was used for estimating a dependent variable from independent variables to determine the level of market co-integration among the market places covered. Trade analysis indicated that production across States is not correlated which create more opportunities for intra-regional trade between Nyala market of SDS and other States of the country for both millet and sorghum provided that trade barriers are removed.
