Abstract
A field trial was conducted in plastic house unit belongs to the Collage of Agriculture / University of Tikrit during 2010 – 2011 season in unheated plastic house ( 450 m^2 ) to study the interactive effect of three dates of transplanting ( 15 / 9 , 15 / 10 , 15 / 11 ) and four sizes of containers for seedling production cup diameter 10 cm , 6.5 cm and stauropore trays of 84 holes and 209 holes ( A , B , C , D respectively ) on vegetative and floral growth and yield of tomato plant ( Wijdanvarity ) which known as a high tolerance variety against virus diseases .used factorial experiment in Randomizer Complete Block Design ( R . C . B . D ) was with three replication . Duncan Multiple Rang Test was used for comparsion of means at 5 % probability . Following results were obtained : first planting date was exceed in plant length , No.plant leaves , No.of flower clusters and No.offolowering buds / plant on other tested sowing dates , container A was exceed as well on retested containers . First and second sowing dates were significantly higher as well in fruits no / plant , average of fruit weight and plant yield and total yield of plastic house on the third sowing date , container A , B and C were significantly higher than containers D in same above mentiond characters . First and second sowing date for the container A were significantly higher in general on the third sowing date , for the container D in character of No.of fruit / plant , average of fruit weight , plant yield and total yield for planstic house
