Abstract
The paper presents preliminary experimental results of the influence of seven ecological fertilizers on the cucumber seeds yield in ecological farming system conditions. The experiment took place in 2019 and the biological material was represented by Mapamond cucumber variety, developed at the Vegetable Research and Development Station Bacău, approved in 2006. The experimental device included seven fertilizers: Funres, Blocks, Azospirillum lipoferum, Azotobacter chroococcum, Bacillus megaterium, Rom-Agrobiofertil NP, Cropmax, by comparison with control variant (untreated). Investigations related to yield components were registered. Rom-Agrobiofertil NP and Cropmax variants exhibit the strongest influence on the seed yield. The highest quantities of cucumber seeds were obtained in the variants treated with Rom-Agrobiofertil NP (V6) - 318 kg ha-1 and Cropmax (V7) - 239 kg ha-1. The study demonstrates the suitability of Mapamond variety to ecological cultivation and also the influence of ecological fertilizers on cucumber seed yield.
