Two field experiments were conducted in 1980 and summer seasons to find out the effect of plant population on the growth, yield and fruit quality of cucumber plants. Sowing cucumber seeds on the wide ridges (100 or 120 cm by width) resulted in significant increases in the number of leaves, dry weight of leaves, branches and total dry weight as well as the relative photosynthetic productivity as compared to those sown on 90 cm apart. Significant and gradual increases were obtained in the total and early yield of cucumber by widening the width of the ridge from 90 to 120 cm, but the early yield percentage was decreased. The quality of fruits expressed as number and weight of fruits per plant, average of fruit and the harvest index followed the same pattern of change as that of total yield. Double sowing per ridge outyielded single sowing with respect to total and early yield as well as the percentage of early yield. The quality of fruits as mentioned above was decreased by the double sowing. Total and early yield increased as a result of the double in the wide ridges (100 or 120 cm) compared with the sigle sowing in narrow ridges.
