We conclude that including leguminous cover crops in a cropping system has the potential to reduce N requirements and improve the N availability and grain yield of the succeeding grain sorghum crop. ... better define the relationship between preplant soil test and fertilizer N requirements, and (ii) quantify the efficiency of crop recovery and conversion of fertilizer N into grain yield for different fertilizer products, management strategies, crop rotations and seasonal conditions. Soils: Sorghum … requirement for Texas grain sorghum is: N requirement: 2 lbs. The researchers concluded that they likely used too much fertilizer on the sorghum, even though it received half the amount as maize. If P fertilizer is needed, rates can be reduced if banded. Grain Sorghum is a great alternative to to corn on dryland acres or marginal ground with less water requirements than corn but similar fertilizer needs. The accumulated growing day degree requirements in excess of 10°C for sorghum are: 145 for seedling establishment, 440 for ear differentiation, 730 up to bud leaf, 880 up to half bloom, 1025 up to dough stage, 170 up to hard kernel stage and 1315 for maturity. Fertilizer application at conventional recommended rates In both cases, to derive the most benefit, the ‘4Rs’ of fertilizer management should be followed: • use the right fertilizer product for the crop • apply the right amount When following soybeans, 10 to 15 percent more fertilizer N … The minimum temperature for germination varies from 7 to 10 °C. While not quite as much of a fertilizer user as corn, sorghum does like its nitrogen. The climatic requirements for the production of sorghum are divided into temperature, day length and water needs. The only way to be sure of the soil temperature is to place a thermometer into the cultivated soil at planting depth at 9am. This is why an integrated soil fertility management (ISFM) approach, which means using good Page | 7 In facilitating training it is essential to understand how adults learn, the role of the facilitator and participatory learning techniques that can be applied. The first method was based on P on applied P uptake, and grain yield relationships for grain sorghum. Temperature also affects flower- ing and flowering occurs best at 22 to 26 °C rather than at 17 to 20 °C. 125 kgs Sulphate or Muriate of Potash/ha. (Usually this is required at the time of planting). At a temperature of 15 Use of pop-up fertilizer placed in direct contact with the sorghum seed is more risky, but can be done successfully by precisely metering a lower rate. Sorghum and millet will give a 60-70% increase in yield if the farmer uses good seed and observes timely planting at optimum spacing, timely weeding and timely fertilizer application. To improve the crop, broadcast an additional 80 to 100 pounds of actual nitrogen (175 to 220 pounds of 46-0-0) per acre 6 to 8 weeks after planting. Thus a 5,000-pound grain yield would need about 100 lbs. E. Variety Selection: Improved short-season grain sorghum hybrids are available, but most of the breeding is for the major grain sorghum production areas, which have warmer, longer growing seasons. All fields are required. Temperature Sorghum is a warm-weather crop, which requires high temperatures for good germination and growth. Overall, summer cover crops can reduce or supplement fertilizer N requirements for grain sorghum production. The rate of starter fertilizer depends on the salt content, or index, of the fertilizer, the distance between the fertilizer and the seed, and the soil texture. The minimum temperature for germination varies from 7 to 10 ºC. fertilizer on their sorghum and millet crops: 1. At a temperature of 15 °C, 80 % of seed germinate Sorghum will perform optimally when planted in deep, fertile and well draining loam soils with a pH between 6.0 and 7.5. Table 1: N, P and K removal, N fertilizer uptake efficiency and predicted milk yield (milk/ton and milk/acre) of brown mid rib sorghum sudangrass in response to N application rate and method (at planting/after the first cut) at the Valatie Research Farm, Columbia County, NY (2000 data). Agronomic requirements Climatic requirements Its seeds germinate best at temperatures of between 20 and 35 °C. Hoe the area daily to stop the growth of any unwanted weeds. In soils with a high sand content, N and K can leach out of the plant root zone under high rainfall or irrigated conditions. The best example of this involves the use of fertilizer. Optimal production under water restrictions or limited irrigation fields. Temperature Sorghum is a warm-weather crop, which requires high temperatures for good germination and growth. sorghum is a “smart” crop, which meets the triple requirements of food, fuel and fodder To assess the potential benefits of sweet sorghum as a feed stock for bioethanol production, a new pilot program is being tested in the state of Andhra Pradesh, under the partnership of B. Nippert 3 and C. W. Rice 1 1 Department of Agronomy, 2004 Throckmorton Plant Science Center, Kansas State University, Manhattan, On imperfectly to poorly drained soils, nitrogen requirements for no-till will differ from tilled cropping systems. Nitrogen requirement is 1.1 pounds/acre for each bushel of grain yield. A list of herbicides labeled for use in sorghum in Nebraska is available in the latest edition of the UNL Guide to Weed Management. Basic requirements Sorghum is a warm-season grass which is adapted to grow in a wide range of soil types and climatic conditions, tolerating waterlogging and poor soils. Safened seed is required if using Dual or Bicep-like herbicides containing s-metolachlor. Sorghum [Sorghum bicolor (L.) Moench] is an important food crop grown by subsistence farmers in Africa with little or no fertilizer. 125 kgs Urea/ha. Grain Sorghum and Soybean Cropping Sequence Affect Yield and Fertilizer N Requirement Author: Kelley, Kenneth W. Source: Crop management 2005 v.4 no.1 pp. 2019 Grain Sorghum The Nitrogen fertilizer should not allowed to contact the seed, otherwise poor germination will result. In Texas this has generally been presented to producers as the amount of N fertilizer to add. 1 Amounts shown are for medium (M) soil test levels. of yield goal. Two methods were evaluated for determining the fertilizer phosphorus requirements (FPR) of sorghum grown on a Vertisol under rainfed conditions. This research provides vital information for producers, especially in developing countries, where, because of high costs and the unavailability of fertilizer N, producers are unable to use fertilizer N for grain sorghum production. Sorghum is mainly cultivated on low potential, shallow soils with a high percentage clay content, not suitable for maize cultivation. Across years, grain sorghum in a double‐cropped soybean system and a fallow system with 90 kg N ha −1 gave profitable economic net returns. sorghum is more tolerant of wet soils than most grain crops. It is best to have fertilizer . Sorghum … The best fertilizer for sorghum will be high in nitrogen with moderate amounts of phosphate and potassium. Contact us to learn how to regenerate your soil, increase plant health, reduce chemical reliance and boost your profitability. Sweet sorghum (Sorghum bicolor L.) offers potential as a renewable energy resource for production of ethanol.Nutrient requirements and nutrient use efficiency will influence the viability of sweet sorghum as a source of renewable energy, since fertilizer represents a significant non-renewable energy input. G1669 Nutrient Management Suggestions for Grain Sorghum. Apply 50% of this r ate if soil test is high (H) and omit if sod test is excessively high (EH). Sorghum potassium (K 2 O) requirements are similar to that of nitrogen. Forage sorghum hybrids should not be sown earlier than mid October in most districts as the soil temperature has to be at least 16 degrees and rising. In these soils a split application is recommended. Print; E-mail. NTS has developed highly successful strategies for sorghum production. Response of fertilizer treatments on agronomic and biochemical traits in main and ratoon crops of sweet sorghum (Sorghum bicolor (L.) Moench) cultivar ICSV 93046 Article Full-text available Sorghum, like other grains, has two basic markets that it serves namely, the human component and the animal feed component.
