Abstract
An experiment was conducted at the field of the Dep. of Hort. Coll. of Agric. Univ. of Baghdad, during the spring season of 2007 and 2008, to study the effect of spraying Gibberellic acid (GA3) and Liquorice extract on some characters of Muskmelon. Spraying GA3(0, 25, 50) mg/l (G0,G1,G2) respectively and liquorice extract(0, 4000, 8000) mg/l (L0,L1,L2) respectively. The plant were sprayed twice at fruit set and 15 days after the first spray. R.C.B.D. as factorial experiment was adapted with three replicate. Results showed spraying of GA3 at (25 mg/l) increased leaf area (6.21 , 5.26 m2), rind thickness (2.28 and 2.20mm), fruit firmness (8.95, 8.06 kg/cm2) and fruit flesh thickness (3.97, 3.65 cm) as compared with G0 for both seasons, respectively. While GA3 at 50 mg/l (G2) increased plant yield (13.71, 11,01 kg) as compared with G0 (11.32, 9.33 kg) for both seasons, respectively. Spraying of liquorice extract (L1) increased leaf area (6.55, 5.71 m2), plant yield (13.23, 11.43 kg), rind thickness (2.36, 1.23 mm), fruit firmness (9.33, 8.08 kg/cm2) and fruit flesh thickness (4.04, 3.42cm) as compared with L0 for both seasons, respectively. The combination treatment (L2G2) was superior on increased plant yield (13.76, 12.47kg) as compared with L0G0 (9.04, 8.52 kg) and L1G1 was superior in increasing of fruit firmness (9.80, 8.83 kg/cm2) as compared with L0G0 (6.70, 6.06kg/cm2) and L1G2 was superior in increasing of fruit flesh thickness (4.20, 3.83cm) as compared with L0G0 (3.20, 2.90cm) for both seasons, respectively.
