Proper fertilization for adequate levels of all nutrients is the best way to maximize standability. (702) Canola Winter Type3. Fertilizer has a significant influence on water use, as illustrated in Table 2. Sustainable sorghum farming strategies – growing tips and fertiliser recommendations to improve sorghum crop quality and yield. Soil tests for some of these nutrients are difficult to interpret. Fertilizer nutrient needs for grain sorghum are based on expected yield, nutrient levels in the soil and fertilizer-nitrogen costs. Recommendations for nitrogen, phosphate, and potash are summarized in the tables that follow. Prior to his current role, he was a Field Sales Agronomist involved in sorghum production with growers in Nebraska. Sulfur can be lacking on sandy soils low in organic matter. Optimum nutrient … Under low rainfall conditions with low yield potential, 30 to 60 pounds of nitrogen per acre may be adequate. • Fe and zinc are the micronutrient most likely to be deficient in Kansas for sorghum. Nitrate is a colorless, odorless, and tasteless compound and it is also one of the most Phosphorus Phosphorus is especially limited when pH drops below 6 or is above 8. Fertilizer management for high yielding grain sorghum Nitrogen is the main building block of plants and is used to make amino acids, proteins and then biomass. Jason Clark . BMR sorghum Phosphorus and K fertilizer rates of 0, 0.5, 1.0, and 2.0 times the recommended rates (recommended rates were 79 kg/ha P2O5 and 101 kg/ha K2O) for the lowest soil test values were applied broadcast and incorporated before planting. See NebGuide G361, Using Starter Fertilizers for Corn, Grain Sorghum and Soybeans. In productive irrigated situations, up to 200 pounds of nitrogen will be required. Extension management recommendations to produce a high yielding, economical grain sorghum crop. Rely on experience and local recommendations to determine the need to supplement these nutrients where a grain sorghum crop is planned. recommendation for an expected yield of 210 bu/A, multiply the 150 bu/A recommendation in the table by 1.4 (210÷150=1.4). Sulfur An often neglected nutrient in grain sorghum is sulfur, which improves nitrogen use efficiency and is especially important as yield increases. Zinc is a nutrient that is often overlooked, but is a crucial element for optimum sorghum production. The fertilizer needs of the crop are often neglected while attention is mostly directed at fertilizing other crops in the rotation. Properly fertilized sorghum used an average of one inch more water than unfertilized sorghum but produced 12.5 hundred weight (22 bushels) more grain per acre. … At boot stage, 65 to 70 percent of the total nitrogen has been taken up. A complex plant disorder associated with high pH soils and soils containing soluble salts that reduce the availability of iron. Both phosphorus and potassium are immobile nutrients in the soil and are generally safe from leaching. -N), soil organic matter, and grain price relative to the price of fertilizer nitrogen. Soil testing is the basis for determining which of these nutrients will likely limit production. He has been with Pioneer Hi-Bred since 1990. Other credits include 15 lb. Toll Free: (877) 643-USCP. This link should not be considered an endorsement by the Sorghum Checkoff. Thus, a good starter fertilizer might range from a ratio of 1-4-0, 1-3-1, 1-3-3, to 1-1-1, depending on the rate of fertilizer required. A general rule to thumb for nutrient removal of NPKS is 24:8:32:5 In some soils, growers also may need to adjust pH to ensure the availability of soil nutrients to the sorghum.
