Abstract
ABSTRACT Two experiments were conducted in Petrolina, State of Pernambuco (PE), Brazil, in order to evaluate the performance of mini tomato cultivars under the conditions of the Sub-Mid São Francisco Valley. One on crops of the second half of the year (SH) from August to December 2012, and other on crops of the first half of the year (FH) from March to July 2013. Six mini tomato cultivars were evaluated in both seasons: E5663, Kada, F1170, Tanzimech, E1275 and Abirú. A randomized block experimental design was used, with four replications, arranged in split plot, with the growing seasons in the plots and cultivars in the subplots. The total and commercial fruit yield, soluble solid contents, fruit yield per plant, number of fruits per plant, and fruit fresh weight were evaluated. The total yield was higher in the FH, regardless of the cultivar used. The cultivar E5663 presented yield of 40.3 Mg ha-1 in the SH and 104.0 Mg ha-1 in the FH. Commercial yield, soluble solid content and yield per plant followed the same trend. The number of fruits per plant ranged from 390.8 to 941.4 (FH) and from 80.5 to 315.4 (SH). The cultivar E5663 presented the best yield and soluble solid content responses, thus, it may be recommended for the conditions of Petrolina PE, and can be adopted for planting in both seasons evaluated.
Highlights
Tomato (Solanum lycopersicum L.) crops in the Brazilian Northeast are conducted mainly by small farmers, especially in the states of Pernambuco, Bahia and Ceará, and has a great socioeconomic importance

Summary
Tomato (Solanum lycopersicum L.) crops in the Brazilian Northeast are conducted mainly by small farmers, especially in the states of Pernambuco, Bahia and Ceará, and has a great socioeconomic importance. The Sub-Mid São Francisco Valley was an important tomato production center during the 1990s and early 2000s, almost all of those fruits was intended for processing. Thereafter, the tomato processing industry declined, and the few producers who remained, kept the habit of grow the same type of materials (cultivars suitable for processing), despite aiming to supply the fresh consumption market. Information on the best tomato cultivars for the fresh consumption market, for various edaphoclimatic conditions, are available in the literature (GUSMÃO et al, 2006; PENA et al, 2010), for the conditions of the Sub-Mid São Francisco Valley, the works so far, were directed to materials intended for processing
