A field experiment was conducted in Al Hasinyia, Karbala Governorate to study the effect of Goat and Poultry manure on availability of few soil nutrients, yield and fruit’s quality of watermelon.

RCBD design was used.

Four levels of Goat and Poultry manure; (4, 8, 12 and 0.00 ton/H)were applied.

Watermelon (Charleston Gray) Seeds were sown on 15/2/2008, first season, and 10/3/2009, second season.

Manure was added (mixed) to the soil in one lot before sowing.

The plots were irrigated frequently (when plants utilized about 75% of soil moisture).

The results showed that adding the Goat and Poultry manure significant increase in availability of few soil nutrients, yield and fruit’s quality.

Poultry manure treatment showed better effect over the Goat manure during the first season.

The treatment of (12 ton/H) showed the highest effect on; nutrients availability, N,P and K, the means were(22.46, 19.63 and 15.72) mg/kg.

It also showed higher effect on fruit diameter, soluble solid content percentage and yield were (14.74 cm, 10.54% 37.35 ton/H) successively.

But during the second season Goat manure showed higher effect over poultry manure on treatment (12 ton/H),which showed the following results , N and P were (15.74 and 17.65) mg/kg, and fruit diameter, soluble solid content percentage and yield (13.18 cm, 10.38% and 37.04 ton/H) successively
