An evaluation of vertical cultivation in selected cultivars Cucumis sativus
2002
Vargova, E. (Slovenska Polnohospodarska Univ., Nitra (Slovak Republic))
The experiment included four cultivars of cucumber - Santana F1, Potomac F1, mostly with pistillate flowers, and parthenocarpic cultivar Harmonie F1. Vertical technique was used for their cultivation in the conditions of southern Slovakia. Within two experimental years (1999 2000), the statistically significant highest yield, both in weight and a number of fruits, was observed for Harmonie F1 cultivar. It was 28% higher in comparison with the mean production of other cultivars. An average weight of fruits ranged from 20.98 to 25.37 g. The same cultivar also showed the lowest water requirement for production of 1 kg of cucumber fruits in 1999, which was 14.5% less than the average water requirement of 86.34 L found in other varieties. In 2000, the average water requirement was greater (129.15 L) because of the longer vegetation period, but Harmonie F1 cultivar again needed 29.75% less water. The total water need for production of 1 kg cucumber fruits was between 74 L and 150 L. In spite of its relatively low resistance to Perenoplasmopara cubensis, cultivar Harmonie F1 is suitable for vertical cultivation, especially in warm and dry areas. Cultivar Santana F1 was found to be suitable in terms of a number of 51-70 mm fruits per kg
