Abstract EN

This experiment was conducted during the season 2004 / 2005 to investigate the effect of incubation (incubate the soil around the base of plant stem) and spraying of zinc at levels (0, 25, 50 mg Zn / l.) as (ZnSO4.7H2O) twice, first before bloom period and the second after (20) days) from the first spray under Plastic house conditions using R.C.B.D design with 4 replicates.

Results showed a significant effect of incubation and spraying of zinc on studied characters.

Plant height, branches number, flowers number, set flowers percentage, plant yield were highest in the interaction of incubation with spraying zinc at level 25 mg Zn / l and caused a significant increase in fruits number / plant and fruits weight with percentage of 38.52 % and 26.21 % respectively from control resulting increase in plant yield, early and total yield with percentage of 74.31 %, 49.54 % and 71.33 % respectively.
