Abstract
Afield experiment was conducted in a plastic house in Al-Tahriyah region/ Babylon Province during 2013/2014 season , soil texture was Loamy Sand with 4 levels of potassium fertilizer (0 , 15 , 30 , and 45 kg K/h) using K2SO4.7H2O, and 4 levels of iron fertilizer (0 , 25 , 50 , and 75 kg Fe/h) using Fe-EDTA, and their interaction on some vegetative and flowering parameters of tomato plant wogdan variety. 4 spraying date among 30 days each, The experiment design was according to RCBD with 3 replicates, means were compared using L.S.D at 0.05 probability level. The result show , the treatment (45 kg K/h) gave significant increases in plant height , total leaf No. , leaf area , plant dry matter , leaf content from chlorophyll, nitrogen, phosphorus, potassium , inflorescense number per plant , and No. of flowers per inflorescense, giving increament percentages 33.62 , 22.95 , 22.78 , 18.10 , 24.79 , 40.94 , 72.97 , 39.16 , 47.25 , and 37.97% respectively compared with the control tratment. While iron spraying treatment gave increasing percentage 13.77 , 30.93 , 8.79 , 9.62 , 38.54 , 31.01 , 33.33 , 44.29 , 41.00 , and 16.65% respectively to the same above parameters . The interaction treatment (45 kg kLh + 75 kg Fe/h) gave the hieghest value of all parameters mentioned above.
