The University of Minnesota is an equal opportunity educator and employer. You will not need sulfur for barley grown on fine-textured soils. As a grain barley is 10 days earlier than wheat. PLANTING  Rate: approximately 1.5 to 2.0 bushels per acre (65 to 90 pounds pure live seed per acre, or 73 to 100 kg per hectare). ft.) 35 Plant Density ranges in the 15 to 50 plants per sq. Regents of the University of Minnesota. 1,250,000 seeds x 110% = 1,375,000 viable seeds needed per acre. Following are the forage seeding rates when seeded alone or in mixtures (Table 1), and adaptation characteristics of legumes and grasses (Table 2). Yield potential in bushels/acre of a seeding rate of 18 seeds per foot of row with 80% germination and emergence and seeded on the recommended seeding date for the area. We suggest using the soil NO3-N test in shaded areas of western Minnesota (see Figure 1). Figure 1. Figure 2. The optimum population is a function of the production environment, the yield goal and the planting date. seeding rate. It’s important to adjust the seeding rate to produce a plant population with a main stem and one or two tillers. Expected stand loss, even under good seedbed conditions, is 10 percent to 20 percent and will increase with a poor seedbed or improper seed placement due to poor depth control. University of Minnesota Extension discovers science-based solutions, delivers practical education, and engages Minnesotans to build a better future. 125 lb/acre PLS if broadcasting, and incorporate seeds with shallow tillage using a field cultivator with harrow attachment (Clark, 2010). Barley production and malt houses were common in colonial Pennsylvania. In general, seed oats at 70 to 90 pounds per acre, barley at 80 to 100 pounds per acre, and triticale at 100 pounds per acre. Some growers also use a midrow band application of anhydrous ammonia, urea or nitrogen solutions successfully. Higher seeding rates may increase lodging, disease potential, and lead to smaller and more variable kernels. Farmers have … Seeding rates should be in the 96 to 120 pounds per acre or 2- to 2-1/2-bushel range. 1,375,000 seeds divided by 14,250 seeds per pound = 96.5 pounds per acre seeding rate, or 28 seeds per square foot. However, diminishing returns and cost of peas suggest that the optimum seeding rate is 50 lb Trapper peas per acre. Seeding rates range from 120 to 150 lbs. Seeding rate (pounds of live seed per acre) Seeding date* Depth; Spring Fall; Grasses; Barley: Annual, cool-season grass: Broadcast:110 to 140 Drilled:80 to 110 : Sept 15 to 30: 1 to 2 inches: Bermudagrass: Perennial, warm-season grass: 20 to 30 bushels per acre sprigged 30 bushels broadcast: March to May : 1 to 2 inches. As a seed grower, there are many times we plant at 25 to 30 pounds per acre with very little yield penalty to a fieldseeded with a normal (?) If planting is delayed past the optimum seeding date for spring-planted small grains, increase seeding rates by about 1 percent for each day planting is delayed. In Minnesota, barley has not responded to the use of zinc (Zn), iron (Fe), manganese (Mn) and boron (B) in a fertilizer program. For winter wheat, increase seeding rates if planting is delayed to compensate for a potentially higher risk of winterkill. If barley is grown on sandy soils, either broadcast 25 lb. For malting barley, the seeding rate should be in the range of, but not exceeding, 300 seeds per meter squared. Seed Rate 100 lbs per acre. It is best to sow the seed with a grain drill at a depth of 1 to 1-1/2 inches. Adjustments to these rates need to be made as follows: Seed at the lower end of the range for early planting and the higher end of the range for late planting (after mid-May). Regents of the University of Minnesota. An average optimum stand for hard red spring wheat, when planted early, is 28 to 30 plants per square foot, or approximately 1.25 million plants per acre. Table 6 summarizes the Cu suggestions. If barley is grown on sandy soils, either broadcast 25 lb. * low = less than 3.0%; medium and high = 3.0% or more. arley is cold tolerant and spring barley can be planted as early in the season as the ground can be worked. Determining the number of seeds per pound and germination rates provides a more accurate seeding rate. Table 6 summarizes the Cu suggestions. Table 3 lists the nitrogen credits for a legume crop grown two years preceding the barley. Barley, buckwheat, canola, corn, grass hay, grass pasture, oat, potato, rye, sorghum-sudan, sugar beet, sunflower, sweet corn, triticale and NS wheat. Increase seeding rates by 20 percent when planting after November 15. Oats and barley have had equal yields in fall forage trials of 1-3 tons of dry matter per acre . The lower rates are most common in drier areas. Nitrogen can be applied with the seed at planting as long as it does not exceed the limits recommended inTable 5. Number of wheat seeds per acre based on thousand kernel weight or seeds per pound and seeding rates per acre. © If you are just throwing the seed on the ground in a broadcast fashion, you … Use Table 2 if the soil NO3-N test is not used. Table 8. Plant malting barley at a rate of two bushels (96 lbs) per acre. 15,000 x 0.95 = 14,250 viable seeds per pound. 1,375,000 seeds divided by 14,250 seeds per pound = 96.5 pounds per acre seeding rate, or 28 seeds per square foot. The number of seeds per pound differs for each variety and can vary considerably between seed lots of the same variety. Seed production fields should be soil tested before planting to determine soil nutrient levels and fertilizer needs. Germination and mortality are based on seed tests. arley is typically planted at 300-350 live seeds per square meter, or around 125 pounds of seed per acre. Effect of oat (var Porter) and pea (var Trapper) seeding rate … You need at least one tiller for optimal root development. Research shows the main stem and the first tiller contribute the majority of the grain yield. Nitrogen fertilizer guidelines can be based on the results of the soil NO3-N test or the consideration of expected yield, previous crop, and soil organic matter content. Take an average weight per 100 kernels. An example for calculating the planting rate for wheat: Desired population is 1.25 million plants per acre at harvest. * Add 20 lb. Small grains planted late normally do not tiller as well as early planted small grains. Emergence Mortality (%) 5% Emergency mortality ranges between 0% - 30%. The next year, 2013, was more mixed. To achieve maximum grain yield, it’s important that the population is optimal. Another advantage of crops with few tillers is that most stems will be in similar development stages. Barley can be planted in the early spring because barley is the earliest maturing small grain species. Subtract these credits from the N recommendations listed for the crop sequence when barley is grown after crops in group 2. In general, data suggest planting oats at about 15 PLS/ft 2 and peas at approximately 8 PLS/ft. Calculating the planting date a cover crop seeding rate: seed all 40-60.
