The effects of fruit thinning, defoliation, and training methods, using lateral shoots for increasing leaf areas, on fruit soluble solids content and yields of tomatoes were investigated. Restricted fruit load per fruit truss by fruit thinning did not result in increment of total yields, marketable yields or fruit soluble solids content. Defoliation and training methods for increasing leaf areas did not influence total yields or marketable yields. Fruit soluble solids content was lowered by defoliation and increased with increasing leaf areas by leaving the lateral shoot just below the fruit truss.
