الملخص EN

The experiment was carried out in plastic houses in the Directorate of Agricultural Research, Bakrajo, Sulaymaniyah during 2012 growing season in order to study the effect of three seed sowing dates (January 15, February 15 and March 15) and black plastic mulching in addition to their interactions on flowering growth as well as yield of eggplant (JAWAHER-F1 cv.).

The results indicated that the firstsowing date was not different significantly from the second date with regard to the total number of flowers and aborted flowers per plant, proportion of the setting fruits as well as some yield characteristics such as total yield per plant and average weight of one fruit.

However, the two sowing dates were superior significantly to the third date with respect to many studied characteristics.

Black plastic mulching resulted in the improvement of the whole studied flowering traits as well as total and early yields and number of the fruits per plant.

The first and second sowing dates and their interactions with black plastic mulching were not different significantly, while they were superior giving the maximum values in the majority of studied characteristics.
