The experiment was conducted during season 2018 in Ain Al- Neser field 20 km north east of Homs to investigate the effects of four irrigation intervals (10, 14, 18 and 22 days), The plots were irrigated by drip irrigation in three sowing dates (15 April-25 April and 5May) on three peanuts genotypes (Syrian2, Syrian, Sahel) on relative water content (RWC%) during growth stages (vegetative-flowering-pod development-maturity).

The treatments were laid out in general randomized blocks design with three replications.

The results of statistical analysis showed that there are not significant differences in vegetative stage between 15, 25 April in Syrian, Sahel cultivars.

There are not significant differences in flowering stage between three sowing dates at Syrian, Syrian2 cultivars.

At pod development stage the plants of Syrian, Syrian2 cultivars didn't gave significant differences in sowing dates 25 April,5May but the lowest (RWC%) of three cultivars was obtained at 15 April sowing date.

In maturity stage the three cultivars gave the highest (RWC %) at 5May sowing date without significant differences between 15,25 April sowing dates.

The 10 days treatment resulted the highest (RWC %) at three cultivars followed by 14 days irrigation interval without significant differences between 18, 22 days treatments, on the other hand the 18 days treatment superiors the 22 days one at Sahel cultivar.
