A goal of 10 to 15 oat seeds/square foot (30 to 45 lbs/a) and four pea seeds/square foot is recommended. Good seed will have a germination of 90-95% and seed mortality is approximately 3%, but can vary greatly. There is considerable variation in pea seed size. If the seeds per pound of a seed lot is not known, the most practical way to obtain this information is to count out 100 seeds two or three times, weigh each sample and calculate the average weight per 100 kernels. The drill seeding rate of 1 to 2 pounds PLS per acre in 45 to 60 cm (18 The accuracy improves as more seeds are counted. Planting specifications: Seeding rate: Seed all at 40-60 lbs per-acre for a cover crop only, 75-100 lbs per-acre for forage. Farmers have … 1,250,000 seeds x 110% = 1,375,000 viable seeds needed per acre. If seeds per pound are unknown, count out 100 seed samples several times. Tables 4 and 5 list guidelines for phosphate and potash fertilizer use, respectively. It’s important to adjust the seeding rate to produce a plant population with a main stem and one or two tillers. Use one of the following equations if a phosphate guideline for a specific expected yield and a specific P soil test is desired. Great for a double crop. Expected stand loss as a function of the quality of the seedbed. 1,375,000 seeds divided by 14,250 seeds per pound = 96.5 pounds per acre seeding rate, or 28 seeds per square foot. As long as seed and fertilizer are separated by at least 1½ inches for urea and nitrogen solutions, and separate… K2O rec = [1.286 - (0.0085) (K soil test)] (expected yield). University of Minnesota Extension discovers science-based solutions, delivers practical education, and engages Minnesotans to build a better future. 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. This rate is applied when you're using a machine called a drill to plant the seed. Nitrogen can be applied with the seed at planting as long as it does not exceed the limits recommended inTable 5. Some growers also use a midrow band application of anhydrous ammonia, urea or nitrogen solutions successfully. The number of seeds per pound differs for each variety and can vary considerably between seed lots of the same variety. As a grain barley is 10 days earlier than wheat. Barley can replace corn in a livestock ration. 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. Table 3 lists the nitrogen credits for a legume crop grown two years preceding the barley. Producers should consider their germination percentage, seedling mortality, seed size (or thousand kernel weight), as these factors can significantly impact seeding rates. arley is cold tolerant and spring barley can be planted as early in the season as the ground can be worked. *Suggestions for marginal soil tests are based on limited trial data. Effect of ryegrass cover crop seeding rate on next year alfalfa yield. Oats: Oats are one of the most widely grown small grain forages in Michigan and are better adapted to cool wet soils than barley. 2021 Germination and mortality are based on seed tests. Desired Plant Density (plants / sq. Seeding rates for small grain/forage pea mixtures should be based on seed size and desired number of established plants per square foot, not just on pounds of seed per acre. All rights reserved. We base these suggestions on a realistic expected yield, previous crop and soil organic matter content. It cannot take very wet areas or may winter kill. If barley is grown on sandy soils, either broadcast 25 lb. Do this up to a maximum rate of 1.6 million seeds per acre. For more detailed charts that include variation in soil texture and soil moisture, refer to the NDSU Extension publication ”Fertilizer Application With Small-grain Seed at Planting”. Calculating the right amount of seed is an important first step toward maximizing yield. University of Minnesota Extension discovers science-based solutions, delivers practical education, and engages Minnesotans to build a better future. An example for calculating the planting rate for wheat: Desired population is 1.25 million plants per acre at harvest. You will not need copper  in a fertilizer program when barley is grown on mineral soils. All rights reserved. Use these credits when the soil NO3 - N test is not used. Compared to a broadcast application, you can reduce rates by 1/2 if using a banded application. BY LEE HART . An increased seeding rate will partially compensate for the decrease in grain yield and the reduction in tillering. The use of sulfur (S) and copper (Cu) may be important for optimum barley production in limited situations. Seed lot has a seed count of 15,000 seeds per pound. Because barley is very susceptible to barley yellow dwarf virus, planting before this time is strongly discouraged. 1,375,000 seeds divided by 14,250 seeds per pound = 96.5 pounds per acre seeding rate, or 28 seeds per square foot. Small grains have the ability to tiller and produce several stems that can produce grain. Connect with Nutrient Management Extension, Alfalfa clover, birdsfoot trefoil, and red clover. In Minnesota, barley is either grown for malting or as a feed grain. S/ acre with the drill at planting. * low = less than 3.0%; medium and high = 3.0% or more. Use this number to calculate the number of seeds per pound. Number of wheat seeds per acre based on thousand kernel weight or seeds per pound and seeding rates per acre. Barley, buckwheat, canola, corn, grass hay, grass pasture, oat, potato, rye, sorghum-sudan, sugar beet, sunflower, sweet corn, triticale and NS wheat. 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 (?) © The next year, 2013, was more mixed. Table 8. Works well when mixed with crimson clover or annual ryegrass. Seeding 40 lb of seed with a weight of 15,000 seed per pound has a yield potential of 60 bushels per acre. Figure 1. Seed production fields should be soil tested before planting to determine soil nutrient levels and fertilizer needs. In general, data suggest planting oats at about 15 PLS/ft 2 and peas at approximately 8 PLS/ft. For winter wheat, increase seeding rates if planting is delayed to compensate for a potentially higher risk of winterkill. In 2005 at Wall in Pennington County, SD, ‛Jerry’ oats, ‛Haybet’ barley, triticale (unknown variety) and annual ryegrass were compared to … To achieve maximum grain yield, it’s important that the population is optimal. Small grains planted late normally do not tiller as well as early planted small grains. Often these low rates are for plot production where seed of new varieties can cost as much as $500 per acre but many times as well for field scale multiplication when seed availability is limited. Alsike clover, birdsfoot trefoil, grass/legume hay, grass legume pasture, fallow and red clover. Plant malting barley at a rate of two bushels (96 lbs) per acre. When using guidelines in this table, there is no distinction between malting barley and feed barley. Seeding rates. The general formula for calculating a seeding rate is: Seeding rate (pounds per acre) = [(desired stand in plants per acre) / (1 - expected stand loss)] / [(seeds per pound) x (percentage germination)]. barley is typically planted in mid to late Septem-ber and spring barley in mid to late April. Oats and barley have had equal yields in fall forage trials of 1-3 tons of dry matter per acre . Table 6 summarizes the Cu suggestions. Following are the forage seeding rates when seeded alone or in mixtures (Table 1), and adaptation characteristics of legumes and grasses (Table 2). When planting oats, barley, or wheat, work to achieve harvest plant populations of 1.0 to 1.3 million plants per acre or approximately 22 to 29 plants per square foot. Barley grown in the first and second years after a legume can utilize the N supplied by legume crops in a rotation. With adequate soil fertility, this grass/legume mixture should not need additional nitrogen applied. This number should increase by 1 to 2 plants per square foot for every week planting is delayed past the early optimum seeding date. S/acre or use 10-12 lb. pH Range – 6.0 and above. Spring barley should be planted in early April to strongly reduce summer weed pressure and maintain yield potential which drops by ~0.5-1 bushel per day after April 15th. 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. (lb./acre) NO3-N, Npc = amount of N supplied by the previous legume crop (lb./acre). Figure 2. The optimum population is a function of the production environment, the yield goal and the planting date. 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). Barley, General Purpose Seeding Rate Calculator. You need at least one tiller for optimal root development. Figure 3. a pound per acre basis. Its use in beer production drove malting barley from the East Coast farther west. You will not need sulfur for barley grown on fine-textured soils. per acre. Best winter barley for grains in the south. Effect of oat seeding rate on forage and grain yield. ft.. 1,000 Kernel Weight (g) 35 TKW ranges between 25 to 50. arley is typically planted at 300-350 live seeds per square meter, or around 125 pounds of seed per acre. Increase seeding rates by 20 percent when planting after November 15. You will not need copper in a fertilizer program when barley is grown on mineral soils. ft.) 35 Plant Density ranges in the 15 to 50 plants per sq. Table 2. If barley is grown on sandy soils, either broadcast 25 lb. The seeding rate for irrigated fields, or fields that receive adequate moisture from rainfall, is 15 to 20 lbs. It is best to sow the seed with a grain drill at a depth of 1 to 1-1/2 inches. Regents of the University of Minnesota. Malting barley was introduced to the United States by the Dutch, English, and French during the time of European settlement and became an important crop for both animal feed and its use in the production of beer. This happens because the crop will go through its development faster as average temperatures increase during the growing season. KEEP SEEDING RATES UP, AND SEED EARLY . NO3-N. Use these credits for the "Npc" factor in situations where the soil nitrate test is used. The higher rates are used for irrigated wheat which often is seeded in narrower rows and later in the season since it often follows another crop rather than fallow. Seeding rates should be in the 96 to 120 pounds per acre or 2- to 2-1/2-bushel range. Varieties that produce few tillers may require higher seeding rates. Gerald Finster aims for a seeding rate that will produce about 22 plants per square foot on fields he’s seeding to Xena feed barley on his Peace River region farm.. We suggest using the soil NO3-N test in shaded areas of western Minnesota (see Figure 1). It is more tolerant of temporary dry conditions than legumes. The optimum seeding depth is 0.3 to 1.3 cm (0.125 to 0.5 in). © 15,000 x 0.95 = 14,250 viable seeds per pound. This illustrates that a 40-pound-per-acre seeding rate of variety 4 will result in the same number of seed per square foot as 60 pounds of variety 2. per acre. seeding rate. Example. N/acre to the credits listed if the 3rd or 4th cutting was not harvested. Nebraska growers use seeding rates for winter wheat that vary from 30 to 180 lb per acre (320,000 to almost 3,000,000 seeds per acre). Excessive seeding, however, can lead to lodging and poor root development. If soil fertility levels are low, consider applying 25 lbs of N/acre between planting and mid- to late-tillering of the barley. Effect of oat (var Porter) and pea (var Trapper) seeding rate … 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.
