Soybean growth stages and requirements
Cold-pressed soybean for poultry
Case study data We examined the effect of the feed used by three different egg producers. These egg producers are located in north-west and north-central Bulgaria. All three are specialised egg and poultry producers with their own feed mills. Two used imported...

Water use and irrigation in soybean
Water requirements at growth stages Soybean uses water efficiently. Depending on weather and soil, it uses 400–700 mm water as rainfall, irrigation or from soil to form a yield of 3 tonnes/ha. Soybean uses 1,300 to 2,300 tonnes of water per tonne of soybean...

Risk management of downy mildew in soybean
Biology The plant pathogen P. manshurica exists currently in more than 30 different races. There is little relevant difference between races in virulence and response to management. This might change due to the ability of P. manshurica to rapidly adapt to the...
Choosing soybean cultivars
Selection criteria Progress to maturity (earliness): selection principles Depending on the autumn conditions of a site, harvesting in September is generally preferred while ripening in October increases risks with weather. The growing season from crop emergence...
Drill-seeding of soybean
Outcome Good crop establishment is the key to high soybean yields. Practical experience has shown that drill seeders are suitable for achieving high yields. Drill seeders sow in narrow rows which contribute to an early canopy closure which increases the...
Harvesting soybean
Outcome Successful soybean harvesting is about recovering the highest proportion of the grain with the best possible quality and purity at the optimal time. Harvest time Harvest should start when the seed moisture drops to 13–15%. The rate of drying primarily...
Mites in soybean production
Outcome Spider mite populations can reach damaging levels very quickly. Infestation can reduce the soybean yield by 40–60%. The protection of the crop from stresses, such as herbicide damage, reduces the risk of damaging infestation. Where chemical control is...

Southern green shield bug in soybean
Outcome The southern green shield bug is a relatively new soybean pest in Europe. It is becoming more abundant and could become a serious pest. Monitoring should start in May or June and continue during July and August. If economic thresholds are exceeded,...
The painted lady in soybean production
Life cycle The painted lady is a migratory species originating from Africa and the Mediterranean. It migrates from North Africa to northern Europe in May and June. The size and shape is similar to other butterflies. The wings are variegated reddish-brown and...
