Generally, early planting comes with the risk of late-spring frost, insect or disease losses, and slug damage.

To figure planting rate, use this formula: You need to plant 7.

This is a function of the crop phenotypic plasticity in response to plant density. If you plan to use a rotary hoe, increase the seeding rate by 10 percent to compensate for plants destroyed by hoeing.

Drilled soybeans, in row spacings of 12 inches or less, account for less than 20% of total acreage.

In recent years, 15-inch and 30-inch row spacings have been the most common planting configurations in North American production, each accounting for over 1/3 of total acreage ( Figure 2 ).

In conducting the analysis, Adee notes that two assumptions were made. com. First, 90% of the seeds would develop into harvestable plants and secondly, seed cost would be $31.

The best planting depth is 3 to 5 cm.

Put beans in the ground 2-3 weeks after the last frost date, when soil temperatures are about 60°F. Jan 28, 2008 · class=" fc-falcon">The optimum number of plants varied from 100,000 to 109,000 plants per acre. Plant seeds at a depth of 1-2 inches.

. Since soybean seed is usually sold by weight rather than by number.

Wet the soil sufficiently so seeds can uniformly germinate.


Timely planting allows for soybean to maximize light interception and canopy photosynthesis, increase number of nodes and seeds per unit area, and lengthen the seed filling period. If you’re aiming to raise soybean yields by increasing seeding rates to the stratosphere, think again.

Planting corn and soybeans after soil temperatures reach 50 degrees F is recommended. .

5 seeds/pod while those under stress will have less.
Soybean row spacings (in inches) in North.



Recommend seeding rates for seed not treated with insecticide or fungicide is around. Generally, a soybean fungicide/ insecticide treatment will cost $10 to $12 per 140,000-seed unit, says Katie Jaeger, Syngenta seedcare product lead. However, heavy rainfall right after planting reduced final stand counts — an average of 73,000 plants per acre — on a field with a seeding rate of 142,000.

Solid seeding was predominant when soybeans first became popular in Missouri and the crop was used primarily for hay. . . Feb 19, 2019 · At another on-farm research site in central Ohio in 2017, soybeans were planted on time, April 27. However. If planting 2 inches deep to access uniform moisture, make sure the variety has an excellent emergence score.


4 bushels per acre. Small-seeded varieties have some advantages: the seed­lings emerge better through crusted soil, fewer pounds of seed are.

Summary • Soybean seed for the 2021 planting season is larger than normal, with some seed lots being in the 18001900 seeds - per pound range.


class=" fc-falcon">Direct Sowing.

Under plough tillage system, it was shown that with an increase in plant height, number of pods per plant, number and weight of seeds per plant, and 1000 seed weight by one unit, the yield increased on average from 0.
