| Abstract | ||
| The experiment was aimed to investigate the effect of different levels of Zinc on the vegetative and flowering characteristic of Somer and supermarimond tomato cultivars grown under unheated plastic houses, during 2005- 2006 season using R.C.B.D. design with 4 riplications . Results indicated that spraying with 50 mg/l zinc twice the first at first flower emergence and the second 25 days after the first treatment was efficient. Highest rates of fruit weight, fruit number, fruit set percentage, flower number, number of shoots and hight for both cultivars used in this trial were improved. On the other hand there was asignificant impact of the treatment on the yield ( kg/plant ) and total fruit yiel | ||
