Abstract

Cape gooseberry is a new crop for Bulgaria. Therefore, the establishment of appropriate technology is important. The main aim of this study was to evaluate the effect of different date of direct sowing outside under Bulgarian condition on the morphological development and on the productivity of cape gooseberry. The experiments were carried out with two varieties cape gooseberry - first Bulgarian variety Plovdiv and Columbian ecotype Obrazec 1 in region of Plovdiv, Bulgaria. Three dates of direct sowing outside - 1.04, 15.04 and 30.04 were investigated. Phenological observations were carried out. In phases of flower bud, flowering and fruiting the height of the stem; number of branches, weight, number and area of leaves, total vegetative weight were established. The total yield was determined. The content in the fruit of dry matter, sugars, total acids, ascorbic acid and pectin were analyzed. The highest yield for both varieties was obtained by sowing 30.04 - 387 kg/da and 341 kg and kg/da for Plovdiv and Obrazes 1, respectively. In this date of sowing and also in 15.04, the plants developed the highest stem, the biggest number of branches and leaf area. The contents of the above mentioned chemical components were highest in the fruits of Plovdiv when sowing was done on 15.04, while for Obrazes 1 – on 30.04
