Milk production has increased and become intensive in some parts of Turkey. In parallel to the increasing milk production, farmers demand high yielding annual legume forage crops for summer seasons in irrigated lands to grow as mixture with maize and sorghum. Regarding this point, cowpea has been conducted in researches more than 15 years. This study was conducted to determine the effects of row spacing and sowing dates of the Cultivar ÜLKEM and a promising forage cowpea genotype on seed yield and some other characters i such as the number of seeds per pod, pod length, thousand seed weight and seed yield. In this study, It was clear that the Cultivar ÜLKEM was superior to the promising genotype; higher yields were obtained in sowing date 1st May; larger row spacing caused decreasing seed yields however larger row spacing had positive effect on other measured characters. The highest seed yields were determined at 30 cm row spacing (121.18 and 141.14 kg per da) for both sowing times. Average thousand seed weights were determined between 157.14 and 187.50 g at 1st May and 155.85 and 178.59 g at 1st June. In conclusion, for high seed yield, cowpea could be sown in 30 cm row spacing at the earliest possible time in spring.
