In to the research including five size of onion bulbs 30–80 mm and three scheme of plant density – 71; 95 and 143 th pl./ha were established that onion seed production, variety Haltsedon, substantially depends on bulbs size and plant density. Seed production per plant grow with in size bulb growing and decreases with plant density growth. In the same time the yield per ha growth with increasing plant density and bulb size. Were established that for every plant density should be used for planting the respective size of bulbs. So for the density 71 th pl./ha the recommended size of bulbs is 50–60 and 60–70 mm, for the density 95 th pl./ha the optimal size of the bulbs is 50–60 mm, and for the density of 143 th pl./ha should be used bulbs with the size 40–50 and 50–60 mm. Bulbs with the size bigger than 50–60 mm used for planting in to the high plant density scheme decrease substantially the efficiency of seed production due to the high planting material costs. |
