How many bushels per acre of soybeans?
The yield difference between 30-inch rows and rows 20 inches or less can be as much as 2.9 bushels per acre, but there are other considerations. Soybeans can be susceptible to disease, with their closed canopy creating a humid microclimate. In areas prone to pathogens like white mold, plant spacing of up to 30 inches may be preferable.

What is soybeans?
A versatile legume, soybeans are a common cash crop that produce at least twice as much protein per acre as most other vegetables or grains. As processed meal or oil, soybeans make their way into human and animal foods, as well as an array of nonfood industrial products and fuel. The soybean is native to East Asia, ...
What is the importance of planting season?
Once planting season begins, it is of utmost importance to follow best practices for safety and environmental stewardship. Time is short. The planting season is hectic. But take time to take extra care.
Where is soybean grown?
The soybean is native to East Asia, but today most soybean production takes place in the U.S. and South America. They are generally grown in a crop rotation with corn, creating good risk management for both crops by breaking disease, insect, and weed cycles, as well as managing farm workflow.
When to use fungicides for seedlings?
Like any input, the cost must be weighed against yield gains. Fungicide treatments are especially helpful if planting early in the spring, as wet, cool soil conditions can add to the risk of seedling disease.
How to increase soybean yield?
High soybean yields are possible with a wide range of plant populations because single plants of most varieties will utilize a 7- to 9-inch area in all directions around the main stem. Plants adjust to tow populations by producing more branches per plant and by increasing the number of pods on both the main stem and branches. There is, however, little change in seed size and in seed number per pod. While the production of more branches and pods per plant maintains the yield potential for soybeans, harvest losses may be greater in thin stands since the pods on the lateral branches will be close to the soil surface and branch lodging is apt to occur. Leaves on plants in a thin stand also take longer to produce a ground-covering canopy. This allows more weed competition and soil moisture evaporation. In contrast, a stand that is too thick may result in excessive early lodging which means reduced yields as well as increased harvest loss.
Why are soybeans high in populations?
When grown under high populations, individual plants produce fewer pods, fewer branches, grow taller, and pod higher off the soil surface than when grown at low populations. Yield potential is maintained with high populations since there are more plants per acre. Soybean populations that are too high also undergo a natural thinning process due to the intense competition between plants, which reduces the stand to a more acceptable level. In other words, plants are eliminated after emergence. In summer, soybean populations can vary perhaps as much as 50 percent from recommended levels without affecting yields, as long as missing plant spaces are not too large and weeds are controlled.
Why is it important to plant soybeans deeper?
Deeper planting will reduce emergence , because the distance a soybean can grow up through the soil is limited. Secondary tillage affects the condition of the seedbed and influences the accuracy of planting depth, crusting tendency of the soil, and moisture retention.
What is the best temperature to test for seed quality?
The most difficult figure to accurately determine when using the above seeding rate formula is percent expected emergence. Percent warm germination is the standard measure for seed quality; every bag of commercially-processed seed in Indiana must be labeled with this information. The warm germination test is run under ideal conditions (i.e., 7 days at 70° F and high humidity) and thus is essentially a test for live seed.
What are the factors that determine the emergence of a plant?
The main ones are soil conditions, weather, date of planting, cultural practices including planting depth, and seed treatment. Emergence response to these factors often is referred to as "seedling vigor"; and all the factors must be considered in predicting percent emergence.
What is the best temperature for soybeans?
In addition to influencing soil conditions, rainfall and temperature play a critical role in the germination and growth of soybeans. Soil and air temperatures of 55-60° F are necessary for seed germination and seedling growth; and as temperatures increase (up to about 90° F), rate of germination and growth likewise increase. Adequate soil moisture is needed to initiate seedling growth, but too much or too little can adversely affect soybean emergence.
Why are soybeans thinning?
Soybean populations that are too high also undergo a natural thinning process due to the intense competition between plants, which reduces the stand to a more acceptable level. In other words, plants are eliminated after emergence.
How much does an Iowa farmer spend on soybeans?
On average a farmer in Iowa spends $25 per acre on seeds (Figure 1). An optimal plant population for soybean production is one that maximizes both yield and profitability. Choosing a seeding rate that is high increases seed cost and may not contribute to a yield increase.
How does soybean compensate for poor stands?
Soybean is able to compensate for poor stands by producing more branches resulting in yields comparable to higher plant populations. However, low plant populations may result in lower pod height, lodging of lateral branches, and higher weed populations, all of which may result in harvest losses.
What is seeding rate?
Seeding rate or planting rate refers to the number of soybean seeds planted per acre to attain a certain plant population. Most farmers find it easier and more reliable to count number of seeds per foot of row or seeds per acre instead of pounds or bushels per acre.
Why are higher seeding rates needed?
Higher seeding rates are needed if speed is too high due to poor seed placement. Emergence and eventual establishment of a soybean stand varies from year to year because of many factors (Table 1). Determination of the plant population is essential after damage by hail, diseases, or herbicides.
How does row spacing affect plant population?
At a given plant population, as row spacing decreases the plant spacing within the row increases and results in a more equidistant plant spacing. At a fixed row width, as plant population increases the plant spacing within the row decreases and interplant competition increases. Obviously, both factors can be adjusted to provide optimal plant ...
What causes poor seeding?
Planting into a poor seedbed, use of poor quality seed, inaccurate planter adjustment, planting too fast, soil crusting, soil moisture extremes, and environmentally induced plant injuries such as herbicide drift, pathogens, insects, hail, or frost all reduce plant population requiring a greater seeding rate.
What is the physiological response to plant spacing?
Physiological response to plant spacing. Plant spacing in the field is very important and plays a significant role in determining plant growth and development. Plant spacing should be thought of as existing in two directions: 1) within row spacing and 2) between row spacing. At a given plant population, as row spacing decreases ...
