To clarify factors which contribute to fruit yield in low-truss tomato cultivation, we investigated the effects of the planting stage and density of seedlings on transplantation on the growth, fresh fruit yield, and yield components. Tomato seedlings were transplanted at four seedling stages, and at two planting densities. Seedlings with 2–3 leaves (Direct planting, no secondary ­raising),­immediately­before­anthesis­in­the­first­inflorescence,­at­the­first­flower­anthesis,­or­at­the­3rd­flower­anthesis­were­ transplanted onto rock wool slabs at 2.6 or 3.9 plants per m2.­Significant­differences­in­the­fruit­yield,­leaf­area­index­(LAI),­and­ total dry matter production (TDM) were observed among the seedling stages and densities at 110 days after sowing. However, neither­the­seedling­stage­nor­plant­density­significantly­influenced­the­light­use­efficiency­(LUE).­Since­the­difference­in­LAI­ caused­the­difference­in­the­fraction­of­light­interception­by­plants,­the­fraction­mainly­influenced­the­yield­and­TDM.­These­ results were also supported by Pearson’s correlation between each yield component. TDM had positive correlations with dry fruit­yield­and­fraction­of­light­interception.­There­was­a­significant­positive­correlation­between­the­fractions­of­light­interception­and­LAI.­Accordingly,­ the­differences­in­fruit­yield­and­TDM­would­be­mainly­due­to­the­fraction­of­ light­ interception­ ­resulting­from­the­difference­in­LAI.­These­suggest­that­there­is­no­improvement­of­LUE­on­modifying­the­seedling­stages­and­ densities­at­transplantation,­and­that­increases­in­LAI­and­the­fraction­of­light­interception­would­increase­the­fresh­fruit­yield­on­ low-truss tomato cultivation.
