Performances of different type intermediate tomato varieties in open field and screenhouse

This study was conducted out at agricultural application and research center of gaziosmanpasa university between april and november in 2015. aim of this study is to determine the effects on different intermediate tomato types in open field and screenhouse on yield and its parameters. the seeds were sown on april 20th,2015. seedlings were planted out in open field and screen house in may 20th,2015. the experiment was carried out randomized complete split plots in block design with three replications. marketable fruit yield (kg) per plant,fruit number per plant,and total yield (kg/m2) were significantly affected by both growing systems and varieties,whereas maturity duration (day) and average fruit weight (g) were significantly affected by only varieties. interactions were no significantly affected. maximum fruit yield per plant was obtained from screenhouse (3.14 kg),it was 2.57 kg in open field. according to varieties,it was highest on merkur fi (4.68 kg),asya fi (3.88 kg),and cemile fi (3.83 kg) varieties. the most fruit number per plant was observed in screenhouse (65.46 numbers per plant),it was 55.96 number per plant in open field. maximum total marketable yield were obtained from screenhouse (16.71 kg/m2). it was 13.71 kg/ m2 in open field. according to varieties,the highest total marketable yield was determined on merkur fi (24.94 kg/m2),asya fi (20.69 kg/m2),and cemile fi (20.41 kg/m2) varieties.
