A field experiment was conducted in Lagawa area, Western Kordofan State, during 1999/00 and 2001/02 growing seasons, to study the influence of three inter-row spacings (75, 100 and 150 cm) and three intra-row spacings (50, 75 and 100 cm) on grain yield and its components of two pearl millet [Pennisetum glaucum (L.) R. Br.] cultivars (Ugandi and Dembi). Data were recorded for number of plants and number of heads per hectare, number of heads/plant and grain yield/ha. The number of heads/plant was the only trait affected by cultivar, and "Ugandi" surpassed "Dembi". With the exception of the number of heads/plant, all traits were significantly affected by inter-row spacing in both seasons and intra-row spacing in the first season and had their highest values at the narrowest spacing. Environmental variability due to seasonality had a grat effect on growth, grain yield and yield components. The interactions among the cultivars, inter- and intra-row spacings for the two seasons were signigicant for grain yield/ha. The best spacing for pearl millet in Lagawa area was 75 x 50 cm for "Ugandi" and 100 x 50 cm for "Dembi". However, these results suggest further research with different cultivars and under different rainfall conditions in order to find out the most suitable inter-row and intra-row spacings and to get maximum benefit from the main yield limiting factor (i.e., soil moisture) which depends mainly on the rate and distribution of rainfall during the season
