الملخص الإنجليزي

A pot experiment was conducted to evaluate the growth and seed production of wilde Hordeum which had grown under different environmental condition .

The study included two factors .

The first was seed burial in soil at (4 , 8 ) cm.

while the second factor , it was grown seed after spray herbecide ( directly, after 1week, after 2week ,after 4week, after 6week, and after 8week).

The results showed that the seeds on 4cm.

depth in soil had supperpass significantly in percentage of emergences than 8 cm.depth in soil .

On other hand , plant that had emerged at 4cm.

seed depth had significantly increased in number of tillers ,number of leaves, dry weight and seed production.The percentage of emergences had significantly increased when grown seed after 4 week spray herbecide .

Grown seed after spray herbecide had significant in number of tillers and leaves / plant , dry weight per plant and seed production if it compered with plants had grown after 8 week from spray herbecide .

The interaction between the seeds on 4cm.

depth in soil with grown after (4,6,8) week from spray herbecide had high percentage of emergences .

High number of tillers and leaves per plant found in the interaction between the seeds on 4cm.

depth in soil with its grown seed after spray herbecide .

High dry weight per plant and high number of seed per spik found in the interaction between the seeds on 4cm.

depth in soil with its grown seed after spray herbicide.
