CONCLUSION
1000-seed weight is more important and effectiveness than other yield contributing and had significant and positive
correlation with grain yield. Harvest index showed highly and positive correlation with percentage of filled spikelet
and grain yield. The results have shown that at the beginning of tillering was so sensitive to irrigation discontinue
because grain yield decreased by reducing of yield contributing like panicle length, number of spikelet per panicle
and number of panicle per M2. Maximum grain yield was obtained with irrigation discontinue treatment at 50 % of
flowering time.
