VARIETY STUDY OF WHITE-HEAD CABBAGE USING ORGANIC TECHNOLOGY IN THE OPEN GROUND

As a result of the conducted research, it was established that varietal characteristics influence interphase periods white cabbage and its yield. The duration period "stairs – beginning formation heads" varied in studies. During cultivation Slavia Slava 1305 varieties, "seedlings 88 89 days, respectively, but plants variety are characterized by more pronounced early maturity compared to varieties. In hybrids, Aquarel F1 hybrids Kubok F1. these options, from 83 84 days. Plants control hybrid Megaton were longer harvesting heads. specified product collection 20 other variants experiment, shorter 1 day relation 2 days variety. Among an earlier head found hybrids. F1, yield exceeded variant 7 –12 %, respectively. On average, during years conducting total between 26.3 27.0 t/ha varieties 30.1 32.6 Cultivation open ground is appropriate because provides increase overall plant 8 % for seedless cultivation.
