A field experiment was conducted to evaluate the response of okra sowing date and variety on growth and yield at the experimental farm of faculty of agriculture, assiut university, assiut, egypt, during 2011 and 2012seasons.

two sowing dates i.e.

april 15 and may 15 and five varieties i.e.

baladyassiut, baladyqena, emerald, golden coast and pusasawani were studied.

from the results it was noticed that the fruit number and fruit yield significantly affected by sowing date and variety.

in case of sowing on 15thapril, the heighest fruits yield was (8.577 and 8.146 ton/feddan) in both seasons.

however 15th may sowing date produced the lowest fruits yield (4.227 and 4.005ton/ feddan).

pusasawani cv produced the highest yield of okra in two sowing dates (12.341, 6.632 and 11.904, 6.365 ton/feddan) in both seasons, respectively.

determination of optimum sowing date is considered an important to have optimum yields.

results shown that varities, golden coast and pusasawani produced higher fruits yield on 15th may than baladyqena cv sown on 15th april.

the interaction between varieties and sowing date was significant in both seasons for plant height, number and weight of green pods/plant and total green yield/fed.
