Field experiment was carried out at Al-Mohamadi city beyond to Heat town-Al-Anbar in the right bank of Euphrates River during 2012-2013 season to study effect of planting dates and calcium spraying on the yield of local cv.

of peanut (Arachis hypogaea L.) and its components.

Factorial experiment in RCBD design with three replication and two factors were used .First factor included six dates for planting (1st and 15th April, 1st and 15th May and 1st and 15 June), the second factor was three levels of calcium (200, 400 and 600 mg Ca.L-1) in addition to control treatment (spray with water only).

The results showed superiority of planting date 15th April in pods No.

(96.77 and 95.17) pod.plant-1, 100 seed weight (81.36 and 85.78) gm for both seasons.

The 1st May was superior in seed No.

(60.90 and 64.00) seed plant -1.

Planting dates on 15th April and 1st May gave highest pods yield about 132.69 and 139.82 gm.plant-1, for both seasons, respectively.

The concentration 600 mg Ca.L-1 was superior in pods No.

(87.44 and 83.42) pod plant-1, seed No.

(89.19 and 94.52) seed plant-1.

The highest pods yield was 123.48 and 128.84 gm.plant-1 from 600 and 400 mg Ca.L-1 for both season respectively.

The combination of planting date 1st May x 600 mg Ca.L-1 at the first season gave the highest pods yield about 150.33 gm.plant-1 while the combination 15th April x 400 mg Ca.L-1 at the second season gave the highest plant yield about 153.35 gm.plant-1.

The conclusion was the early planting during April and May were best in compared to June planting and spraying 400 mg Ca.L-1 was best for pod yield of peanut.
