Summary: | A field experiment was carried out in Alsufia - Al-Ramadi city - Al-Anbar governorate Republic of Iraq at winter season 2020-2021 on sandy loam soil. The experiment included 12 treatment resulted from the combination of planting date Oct25, Nov10, Nov25 and Dec10 ( main plots) and kinetin concentration 0,30 and 60 mg L
-1
( sub plots ) using RCBD with split plot arrangement and three replications. The results revealed that the plants of first planting date recorded 91 days until booting stage and reduced gradually to 60 days at fourth date. First planting date score highest thermal accumulation at 1876 C and declined to lowest value at third date (1389) C. Fourth planting date gave the highest CGR (0.127) g day

and NAR (0.00028) g cm

day

. The concentration of kinetin 30 mg L

surpass in CGR significantly, but kinetin concentration have on significant effect on NAR. |
