\textbf{Abstract}
\begin{abstract}
\normalsize{
Field experiments were executed for two successive seasons (2009 and 2010), at the southern area of Gedarif state with the objective of studying the influence of sowing date and population density on the productivity of a land race Bambara groundnut. Four sowing dates, \textit{viz}., 27\textsuperscript{th} of June, 9\textsuperscript{th}, 19\textsuperscript{th} and 27\textsuperscript{th} of July and five combinations of inter"=row*intra"=row spacings, 40cmx\mbox{30\,cm}, 40\,$\times$\,20, 30\,$\times$\,30, 30\,$\times$\,20 and 20\,$\times$\,20, were used during both seasons. The data recorded in both seasons were plant height, canopy width, 100 seed weight, shelling \% and pod yield ton/ha, Results revealed highly significant differences in almost all measured parameters with respect to sowing date. Early sowing resulted in a significantly higher pod yield ton/ha when compared to late sowing (4.3, 2.3, 1.3 and \unitfrac[0.94]{ton}{ha} respectively). Variable plant spacing significantly affected pod yield during the first season, while no significant variation was observed during the second season. Nevertheless, better yields were obtained with wider spacings.



Based on the findings of this study the following recommendations are suggested to be released to the farmers:



1.	Bambara ground nut has a high potential under rain fed conditions of south Gedarif and thus can be considered as one of the potential crop choices in the targeted area



2.	Late June to early July is the optimum sowing date range for the Bambara groundnut in South Gedarif area.



3.	40--\mbox{30\,cm} inter"=row spacing and 30--\mbox{20\,cm} intra"=row spacing is the optimum spacing for Bambara ground nut production under rain fed conditions of South Gedarif.
