Testing results of new technologies in onion and carrots seeds production
Original technologies of onion seeds growing on irrigated fields with the yield about 500-700 kg/ha were offered. Economy process of onion seeds growing is two harvest crop - harvesting seeds in the next year on the same field from the same plants, shooting from the brood bulbs. The seed yield in two harvest crop was only 6-14% below in comparison with traditional technology (planting mother bulbs in spring). Two harvest crop can be used only singly, in addition to main seed growing technology. It is possible in Moldavia conditions to grow onion seeds from small bulbs by planting them in the end of august and harvesting seeds the next summer. The seeds yield is only 15% lower than by traditional technology, and first cost of the seeds was 30-35% lower. Spraying of the plants with the solutions of microelements and plant grows regulators enhance seeds setting, seeds yield and seeds quality. The positive influence of inner cultivar pollination on the yield and quality of carrot's seeds was evaluated in the field's experience. In Moldavia conditions the technology of carrots seeds growing from seedlings (sowing seeds in 10-12 of august and storage of seedlings in plastic tunnels during the winter) is perspective. The yield of high quality carrot's seeds was about 764-750 kg/ha.
