Yield and quality of cucumber (Cucumis sativus L.) grown under greenhouse conditions

Abstract

Yield and quality of five parthenocarpic American type cucumber genotypes (Cucumis sativus L.) grown under greenhouse conditions were evaluated during the dry season in Alajuela, Costa Rica. The harvest begun at 31 days after transplant for all genotypes. Data show a wide variability between genotypes with respect to fruit length (21,10 – 23,85 cm), fruit diameter (48,57 – 49,97 mm), total number of fruits per plant (21,63 – 24,31), mean fruit weight (304,51 – 378,51 g), yield per plant (6748,11 – 8540,18 g/plant), commercial yield (15,12 – 19,04 kg/m2), total yield (17,53 – 22,18 kg/m2), and percentage of total soluble solids (3,40 – 3,89 °Brix). Modan genotype obtained the lowest first quality yield. Primavera and Corinto genotypes obtained the highest commercial yield (19,04 and 18,27 kg/m2, respectively).
