![]() ![]() The percentage of heaving was lower than 50 per cent when the weight of the obstacle was greater than 0.1 N.Įmergence (heaving and escape) was greatly reduced if the seedling encountered an obstacle with a diameter greater than 3 cm. To obtain the moment of the clod weight equal to the moment of the seedling force, the probability of heaving was determined after about 6 hours by using the statistical distribution of the forces developed during this period. Once your seedlings have gotten to a healthy size of about 2-3 tall, you can plant your beet plants in your garden. It appeared that the seedlings were able to lift obstacles the weight of which was greater than the growth force because the hypocotyl moved under the obstacle. Beets, Beta vulgaris, are herbacious biennial root vegetables in the family Chenopodiaceae grown for their edible root. Use a pair of scissors to cut the seedlings off at the soil line. ![]() If the seedlings were under a seedbed with clods, one of two processes were involved in emergence : the seedling lifted the clod or it grew under the clod to escape. When the beets are 2' to 3' tall, generally five weeks after planting, they need to be thinned to one plant every 6'. The emergence percentage was lower than 50 per cent as soon as the resistance of the crust was greater than 0.2 N and the maximum emergence percentages were reached after about 40 hours. If there was a crust at the surface of the seedbed, the calculated probability of emergence was estimated from statistical distribution of hypocotyl forces by using a mechanical model of rupture with bending and fracture. Relationships were established between the physical and mechanical characteristics of these obstacles and the growth force of the seedlings measured beforehand, which made it possible to develop a predictive model of the percentage and kinetics of emergence. Sow your beetroot seeds 2cm (3/4'-1') deep. The emergence of sugar beet through two types of seed beds, one encrusted and the other made up of obstacles independent of the underlying layer, was studied in the laboratory. ![]()
