Abstract
A Study Was carried out in the agricultural experiment station, Agriculture Collage , Tikrit University during growth season 2008-2009to know the Effect of Foliar nutrition by Marvel solution concentrations (0.5, 1and 2 m/ L) spray in three periods on Growth and yield of two varieties of Lettuce ( Local Lettuce and Paris Island ). Results demonstrated that the Paris Island variety superiority on Local Lettuce variety significantly in all studied characters ( length growth , number of leaves ,diameter of length diameter in head , fresh weight and dry weight of leaves , fresh weight to sealing and yield total ) respectively . Results revealed that concentration of nutrient solution Marvel have significantly effects on all studied characters for both varieties, Treatment 2 mL/L gave highest values for studied characters (length growth , number of leaves ,diameter of length diameter in head , fresh weight and dry weight of leaves , fresh weight to sealing and yield total) for both varieties ,they were 30.34 cm,45.67 leaf/plant, 4.12cm,14.32 cm,261.86 g/plant,74.95 g/plant,756.58 g/plant and 15.40 ton/h contrast with control treatment (26.67cm, 33.00leaf/plant, 3.20cm, 11.70cm,230.80 g/plant,49.50 g/plant,467.30 g/plant and 13.04 ton/h. The values of the interaction between variety Paris Island and concentrations of nutrient solution Marvel were higher for all studied characters, they were(33.68cm,53.00 leaf/plant,4.74cm,15.43cm.288.56 g/plant,97.63 g/plant,989.53 g/plant and17.12 ton/h) respectively .
