What population do you plant soybeans?
As a general rule of thumb I recommend farmers purchase a bag of seed per acre (140,000 seed count) and plant that entire bag per acre (140,000 seeds) (Figure 1). Remember your target is to get a minimum stand of 100,000 plants per acre as this population will achieve 100% yield potential in most field environments.
What is the best population for soybeans?
Purdue research suggests that a final stand of 80,000 plants per acre (in 30 inch rows) is adequate for achieving 100% of yield potential. South Dakota research points to an ideal soybean planting population of 140,000 seeds/acre.
How do you calculate soybean population?
To determine stand count on 30″ rows it is just like the example above for corn. For soybeans planted on 15″ rows, you double that distance and measure off 34 feet 10 inches and count the plants. The number of plants x 1000 = plant population in plants per acre.
How many acres will one bag of soybeans plant?
bag of soybean seed will plant one acre, you will multiply 100 acres by the cost of the bag, $15.49, to find the total cost of planting your soybeans.
What is the best row width for soybeans?
Row spacing is a management decision that often comes up as a priority for achieving high-yielding soybean. Research across the Midwest over several years has consistently shown that soybean planted in narrow rows (<30 inches) has a yield advantage compared to wide rows (≥ 30 inches).
Can you plant soybeans 2 inches deep?
Soybean seed can be planted up to 2 inches deep in sandy soils. Adequate soil moisture is the most important factor affecting soybean germination. If you must plant deeper than 1.5 inches in order to place the seed into uniform moisture, make sure the variety has an excellent emergence score or long hypocotyl.
What is the best fertilizer to use on soybeans?
Soil pH of 6 – 6.8 is ideal. Banding fertilizers and foliar feeding are common application methods but should be considered only when conventional methods are not satisfying. Soybeans grains have a nitrogen content of 40%, therefore an adequate fertilization of nitrogen is a key factor in achieving high quality yields.
What is the best row spacing for soybeans?
between 7.5 and 15 inches
Purdue Extension recommends row spacing between 7.5 and 15 inches for maximum soybean yield. Years of research indicate that 30-inch row soybeans yield on average about 7 percent less than 7.5- or 15-inch row soy- beans (Hanna et al., 2007; Oplinger and Philbrook, 1992).
How deep should you plant soybeans?
Under most conditions, soybeans should be planted between 1 and 1.5 inches deep. As a general rule, plant at the shallower end of the range under the following conditions: Early planting….Planting at the deeper end of the range is recommended under the following conditions:
- Late planting.
- Coarse-textured soils.
- Dry soils.
How many acres can be planted per pound of seed?
1077 acres
Each pound of seed one can plant 1077 acres or 5657.14 square feet.
How much does a 50lb bag of soybeans cost?
Feed Soybeans Roasted 50 lb.
| 1 – 39 units | $29.50 ea. |
|---|---|
| 40 + units | $28.00 ea. |
Which fertilizer is best for soybeans?
Fertilizer Application
- Apply 20 kg N and 80 kg P2O5 and 40 kg K2O and 40 kg of S as gypsum (220 kg/ha) /ha as basal dressing.
- Soil application of 25 kg ZnSO4/ha under irrigated condition.
- Foliar spray of NAA 40 mg/l and Salicylic acid 100 mg/l once at pre-flowering and another at 15 days thereafter.
How big is a soybean row in Ohio?
In Ohio, most soybeans are planted in row widths ≤ 15 inches. Soybeans grown in narrow rows (≤ 15 inches) tend to out-yield soybean produced in wide row width (30 inches) due to increased sunlight interception in narrow rows.
How many soybeans per foot in a row?
It is recommended to count the number of soybeans in three to five feet of the row to get an estimate of beans per foot. This approach minimizes bias to avoid areas with poor plant spacing, large gaps or thin plant populations.
What’s the difference between 15 inch and narrow row soybeans?
Soybean acreage in drilled narrow rows has declined across North America in the last five years, while acreage in 15-inch rows has increased. Factors such as equipment costs, workload management, planting and harvest efficiency, and weed and disease control can all influence the economic viability of narrow-row soybeans.
What’s the best spacing for a soybean plant?
AY-217-W Plant Populations and Seeding Rates for Soybeans Purdue extension. 2 Purdue Extension recommends row spacing between 7.5 and 15 inches for maximum soybean yield. Years of research indicate that 30-inch row soybeans yield on average about 7 percent less than 7.5- or 15-inch row soy- beans (Hanna et al., 2007; Oplinger and Philbrook, 1992).
