The ratio of nitrogen, phosphorus and potassium is 10.51.2. Mustafa and Manures and Fertilizers in Sorghum Production:-Proper application of manure and fertilizers on time ensures good crop growth and high yield. Was calculated using the following equation: Characteristics of soil sample of experiment site at 30 cm depth, EC: Exchange capacity, CEC: Cationic exchange capacity, OM: Organic matter, P: Phosphorus, K: Potassium, Effect of N levels on plant height and leaf area index, NB: Levels not connected by same letter within the same column are significantly different, Effect of N levels and varieties on panicle length and yield per panicle thousand seed weight, Effect of nitrogen levels on Agronomic Nitrogen Use Efficiency (ANUE), Main effect of nitrogen on N-uptake (kg N ha. The test data shows that for every 100kg of sorghum grain produced, it is necessary to absorb 2.6kg of nitrogen (n), 1.36kg of phosphorus (p) and 3.06kg of potassium (k). Striga spp. These were used to estimate Agronomic Nitrogen Use Efficiency (ANUE), Physiological Nitrogen Use Efficiency (PNUE), Apparent Nutrient Recovery Efficiency (ANRE) and total nitrogen uptake of sorghum using the following equation: Statistical analysis: All data collected was subjected to the analysis of variance for using “JMP” statistical software package Version five. Falls, S.A. Siegel, in Encyclopedia of Analytical Science (Second Edition), 2005. randomized complete block design with three replications. Three nitrogen levels (0, 75 and 150 kg ha-1) were applied in three grain sorghum cultivars in a Turkish experiment (Güller et al. Sorghum is cultivated on Vertisols in the Ethiopian Highlands. Because micro dosing reduces the amount of fertilizer used, it helps to decrease nitrate levels in groundwater and surface water. The micro dose technology was so successful in the targeted regions that the National Directorate of Agriculture recommended that all millet and sorghum farmers apply it. leaf area index, panicle length, yield per panicle, 1000 grain weight, grain Sorghum cultivars are known to vary in their response to fertilizers. Trifold Chinch Bug Plan:  Chinch bugs are a threat to sorghum at three stages. The nitrogen fertilizer rates were applied to corresponding experimental plot divided in to two halves. Field experiments were conducted in … Therefore, there can be no doubt that steadily increasing the fertility of the land which includes providing a good level of nitrogen in the fertilizer used is an essential component of any Striga control system. There are limited options for post grass control so scout heavy early and respond aggressively to escapes while they are small. Nitrogen level of 150 kg ha-1 gave the highest thousand seed weight (26.7 g) which was comparable with nitrogen application at 100 kg ha-1. Ouedrago previously harvested only 0.7 tons of crops per hectare on his millet and sorghum farm. 2,100, in which Rs. Fertilizer application of 100 kg N and 60 kg P 2O 5/ha for multicut sorghum and 80 kg N and 40 kg P 2O 5/ha for single cut sorghum is recommended. Check out the sorghum soil management page for current University of Nebraska-Lincoln Extension recommendations for nitrogen, phosphorus, potassium, zinc, iron, and sulfur. Map of the study area (Mechara Agricultural Increase in grain weight at higher nitrogen rates might be primarily due to increase in photosynthetic rate which ultimately produce sufficient photosynthates available during grain development. Mustafa and Abdelmagid (1982) has also shown that application of nitrogen fertilizer increased plant height in sorghum. Residue also shades the soil and reduces evaporation loss from the soil surface. (2006) as in the presented study, reported a positive effect of nitrogen fertilizer application on the harvest index on grain sorghum. 1,000 for farmyard manure and Rs. Band application of phosphorus fertilizer on low phosphorus soils is suggested for corn and grain sorghum to maximize fertilizer use efficiency. As a result, the crop has been and is still an important staple in the Semi-Arid Tropics (SAT) of Asia and Africa (Jambunathan et al., 1984). Different authors also reported the negative effect of nitrogen on Striga growth and development. Results (1974): Data on Striga days to first emergence, branch per plant, plant height and Striga count per plot were recorded. In agreement with the present finding Sinebo and Drennan (2003), reported reduced height and weight of the parasite weed S. hermonthica with nitrogen application. Similarly, Agbobli (1991) reported application rates greater than 60 kg N ha-1 reduced number of emerged Striga asiatica in maize crop. Moreover, nitrogenous fertilizer may enhance the degree of resistance shown by resistant sorghum cultivars (Ramaiah and Parker, 1982). The Striga found in Northern Ethiopia shows greatest diversity in morphology and behavior attacking exceptionally wide range of crops as compared to the Striga spp. Many grain sorghum varieties grow to only 5 feet tall, but sweet sorghum and broom corn plants can top 8 feet. The enhance in grain yield with increase in N levels application might be due to the increase up of yield attributing characters and nutrient uptake of the crop under these levels as well as reduced Striga infestation at high application levels. This helps to take the E (evaporation) out of ET (evaporation & transpiration), which are the water use components. consisted of four rates of nitrogen (23, 46, 69 and 92 kg N ha-1) and three time of N application (1/2. Decrease in Striga plant height was observed with increased nitrogen level application. Results from a crop rotation study conducted by Paul Hay from 1994-2005. The increased panicle length at high level of nitrogen application might be due to high nitrogen uptake under these treatments. Data on sorghum growth parameters and yield components as well as some Striga Lowest harvest index was obtained in the control and with 50 kg N ha-1 application. Sorghum [Sorghum bicolor (L.) Moench] is an important food crop grown by subsistence farmers in Africa with little or no fertilizer. This is not the way those choices should be made. Effect of nitrogen on Striga plant height, branching and count per plot: As depicted in the Table 5 and Fig. One meter and 1.5 m distances were maintained among plots within replication and between replications, respectively. (C01) Corn (for Grain) Irrigated 200 bu/a It is a short duration crop of 110-130 days as compared to 12-18 months in sugarcane. kg/haand fertilizer levels (three: 60:30, 80:40 and 100:50NP kg/ha) fertilizer dose for getting maximum fodder yield of sorghum CSV-21F. Communications Bldg.Lincoln, NE 68583-0918. crop for many growers. The field was ploughed twice using traditional oxen drawn plough before planting and seedbeds were prepared using human labor. study was conducted during 2008 (2000/01 E.C.) Now, with the micro dose technology, he can harvest up to 1.2 tons per hectare. Benth is the most tenacious, prolific and destructive Farmers who use microdosing apply 6 gram doses of fertilizer—about a full bottle cap or a three- finger pinch -- in the hole where the seed is placed (at the time of planting). Sorghum Production: Sorghum is one of best millet crop for food and forage (fodder for livestock). The Association of Fertilizer and Phosphate Chemists administers two check sample (or proficiency) programs that are utilized by manufacturers, customers, and regulatory agencies throughout the world. Cowpea residues resulted in microbial immobilization of added and mineral soil N and P. N/P ratios suggested more microbial P than N limitation in organic amendment treatments. Microfertilizing, consisting of applying small amounts of mineral fertilizer to the planting hole or pocket, was tested in Mali. Cechin and Press (1993) reported that application of nitrogenous fertilizer like ammonium nitrate affect Striga emergence either by reducing production of stimulatory compounds or their specific leakage from host roots and Kabambe et al. 75, 100 and 125 per cent of recommended dose of fertilizer (RDF). Productivity of sorghum is limited by soil fertility. https://scialert.net/abstract/?doi=ijar.2015.14.23, Maximum leaf width (cm)xMaximum leaf length (cm)x0.747. In-furrow insecticides increased corn grain yields by as much as 1823 kg/ha. showed that application of N-fertilizer significantly increased plant height, This is particularly true as you move west in Nebraska to dryer and warmer summertime soil temperatures. Sorghum is produced in virtually all the States in Nigeria, though some States produce more than others. On the other hand, the lowest 1000 grain weight was recorded from the control and plots receiving 50 kg N ha-1. Don't be afraid of taller hybrids. Optimal yields were produced with micro-dose application plus 20 kg/ha P and 30 kg/ha N. (2000) The keys to weed control in milo are Early Preplant (EPP) and Days Before Planting (DBP) listed in the University of Nebraska-Lincoln Extension Guide for Weed Managemen (See the Sorghum Weed Management section). July is greenbug month. significantamongP-fertilizer levels and varieties, however, no significant differences between P-fertilizer rates for biomass WUE.P-application increased grain WUE of sorghum by 20-39%, the ICSV400 estimated the mean highest value of 9.3 and 8.6 kg ha-1mm-1 over CSR-01 and local at both Significantly, highest Striga plant heights were recorded from the control and the lowest nitrogen rate (50 kg ha-1) (35.2 and 34.2 cm, respectively). However, the result showed that the effect of nitrogen on harvest index is not directly proportional with increase in nitrogen levels. Treatments in August most often kill the greenbugs after the damage has been done. Please check the Crop Watch Calendar for Upcoming Events! Keywords: Biomass WUE, crop evapotranspiration (ET c), Grain yield WUE, P-Fertilizer effect, sorghum … The result also indicated that the soil had Cation Exchange Capacity (CEC) of 30.8 meq/100 g, 1.06 ppm available phosphorus, 224.5 ppm available potassium and 0.043% total nitrogen. Soil nutrient deficiency and rainfall variability impair the production of sorghum (Sorghum bicolor (L). UNL web framework and quality assurance provided by the, Apply to the University of Nebraska–Lincoln, Give to the University of Nebraska–Lincoln, Institute of Agriculture and Natural Resources, Strengthening Nebraska's Agricultural Economy, USCP Central & Eastern Plains Production Handbook, Additional sorghum production information can be found at the. When the herbicide is in place for the later planted crop, it saves moisture and gives the producer added options for both grass and broadleaf control. production is constrained by many biotic and abiotic factors amongst Striga dose fertilizer application, improved sorghum and maize varieties, the basin tillage practice of zai and reducing runoff and erosion with stone barriers or earthen bunds. application over the control by 9.54, 35.76 and 36.95%, respectively. June and October) season. The biomass sorghum (Sorghum bicolor L. Moench), Palo Alto® hybrid was sown in December 2015 with NPK planting fertilizer, recommended for forage sorghum []. hermonthica (Del.) Levels of nitrogen fertilizer from 110-170 kg N ha-1 were reported to control Striga hermonthica in sorghum (Showemimo, 2007). corn, sorghum and wheat. On-station and on-farm trials were conducted for two consecutive seasons (2009/2010 and 2010/2011) at Al-Tukma village (12°00′57.60′′ N and 29°46′12.15′′ E) in South Kordofan State, 15 km southeast of Dilling city. The control measures include; crop rotation, catch cropping, hand-pulling, nitrogen fertilization, intercropping, solarization, chemical (herbicides and or artificial seed germination stimulants, e.g., ethylene, strigol analogue), use of resistant varieties and biological control. Increasing seed rate significantly decreased the … Among the pests, the root parasitic weed Striga has long been recognized as the greatest biological constraint to sorghum production in the region. In addition its water and fertilizer requirement is much less, resulting in lower cost of cultivation than sugarcane. The amount of N credit varies with crop, stand, yield, and other factors. of four nitrogen fertilizer levels (0, 50, 100 and 150 kg ha-1). N0 (no nitrogen), N1 (50 kg N ha-1), N2 (100 kg N ha-1), N3 (150 kg N ha-1) laid out in a randomized complete block design with three replications. Due to the need to monitor Striga emergence without obstruction and quantify the effect of Striga only, plots were kept free of weeds by repeated hoe and hand weeding at all growth stages. Thinning should be done before hilling-up or side dressing the second fertilizer dose which is 14-21 days after emergence. The Southwesterly monsoon winds bring rainfall The plant’s capacity to produce Right behind Harrison was Jim Boehike in Idaho and Ki Gamble in Kansas with yields of more than 230 bushels. The highest grain yield was obtained with 150 kg N ha-1 (2231.48 kg yield ha-1) application which was comparable with 100 kg N ha-1 (2083.33 kg ha-1 grain yield) application. The grain yield improved with increased levels of nitrogen fertilizer application. This finding confirms the results reported by Showemimo (2007) which stated nitrogen fertilizer application from 110-170 kg of N ha-1 control S. hermonthica in sorghum. ... Sweet sorghum has less water and fertilizer requirements and hence lower cost of . These Declining soil fertility and low rainfall are key constraints to crop production and are threatening food security in semi-arid areas. J.H. Effect of spacing and fertilizer dose on growth and yield of potato (Solanum tuberosum L) Gudane variety at West Hararghe, Eastern Ethiopia Int. Sweet sorghum is remarkably drought-resistant and resists months of dry weather until rains resume. Increasing nitrogen application from 50-100 and 150 kg N ha-1 increased ANUE by 59.2 and 53.8%, respectively. A field experiment was conducted on deep vertisols of Bhopal, India to evaluate the manural potential of three organic manures: farmyard manure (FYM), poultry manure (PM), phosphocompost (PC) vis-a-vis 0%, 75% and 100% recommended dose of fertilizer-NPK and to find out the most productive cropping s … If the phosphorus level in the field is low, starter fertilizer is an excellent way to get the phosphorus efficiently placed for top response. Association of Fertilizer and Phosphate Chemists Check Sample Program. Significant uncertainty remains in predicting climate in Africa, increasing the challenge of planning for climate change adaptation. This critical component determines if nutrients in the soil can be taken up by the plant. In general the positive effect of high dose Seed treatment insecticides can help in the seedling stage and to a lessor extent after the wheat ripens. found in any other sub-Sahara African countries (Fasil, 2003). In all management decisions including harvest, the milo producer who treats it a first class crop is going to be more successful. Sorghum (Sorghum bicolor L. Moench) is an important food crop in Ethiopian. Striga hermonthica is the most widely distributed and devastating species in Northern Ethiopia severely affecting sorghum yield, the second most important crop in the region. Numbers of Striga germinated per plot were lower in plots treated with nitrogen at a dose of 150 kg ha-1 (15.9) while highest numbers of Striga per plot were obtained in none treated plots with nitrogen (25.2). fertilizer dose. It contains B-vitamins like thiamin and riboflavin. fertilizer until the nodules are formed. This result disagrees with previous findings. Soil test levels and past yield goals will tell you the nitrogen fertilizer addition you will need and the response you might expect from phosphorus and zinc. V CONCLUSION Mechanized zaï and micro dose of NKP fertilizer gave high level of root biomass on sorghum (760 kg ha -1 in the layer 0-40 cm). ect of nitrogen fertilizer application on the growth and ethanol yield of sweet sorghum varieties in the Southern Guinea Savannahagroecological zone of Nigeria. application on yield and yield components of sorghum in northern Ethiopia. This roots system is favorable to sorghum … Modern grain sorghum hybrids have the ability to yield much more than what the casual grain sorghum grower usually realizes. Since 2014, subsidized fertilizer has decreased from nearly 11.8 million tons to 4.1 tons — a savings of 7.7 tons. (701) Canola Spring Type2. Farm productivity is also at risk from extreme weather and future climate change. This study was undertaken with the objective of evaluating micro-dosing of mineral fertilizer combined with seed priming in sorghum, groundnut, sesame, and cowpea. If you feel you have to part the residue, do so without moving soil. Striga plant height, number of branches per plant and Striga plant Select a top performing hybrid from one of the seed companies who are proud to sell milo seed. Soils with a Placement of starter fertilizer in the seed furrow, commonly called “pop-up”, requires care to prevent germination injury from fertilizer salts. The shares of irrigated and rainfed sorghum in total fertilizer consumption were 0.5 and 2.4 percent, respectively. (2008) reported fertilizer application promoted Striga emergence. Top dressing: It is the application of manures and fertilizer… Progress 10/01/02 to 09/30/03 Outputs Micro-dose fertilizer yield response of grain sorghum and pearl millet was not uniform across locations, but on average increased grain yield by 35% and stover yield by 61% in Burkina Faso, Mali and Niger. Soil pH. Yield per panicle increased with increasing of nitrogen levels. growth and its indirect effect by reducing Striga infestation which was Crop residue does this in two ways. What about a burndown with glyphosate at planting or pre-emerge treatment? Phosphorus (P) requirements for sorghum are slightly less than corn. Increased application of nitrogen results incoherent augmentation of ANUE (Fig. Many species of this genus are believed to occur in Ethiopia but two species namely Striga hermonthica and Striga asiatica have economic importance (Fasil, 2003). Plants 012 Figure 1. Grain sorghum draft paper (organic fertilizer enrichment) 13 Executive summary • New genotype ‘SPV2468’ with 15.8% higher grain yield was promising to chekcs (3.6 t/ha) at DharwadSorghum . Soil nutrient deficiency and rainfall variability impair the production of sorghum (Sorghum bicolor (L). The area has a unimodal One, in the seedling stage when chinch bugs are present because of poor control or too late control of grasses like volunteer wheat. Abdelmagid (1982) has also shown that application of nitrogen fertilizer That translates to about 67 pounds of fertilizer for every 2.5 acres. So a solid before planting program is the best. Pre planting soil analysis illustrates that the textural class of the soil is clay (52.36%) with soil pH of 7.4. On the other hand, the lowest plant height (120.83 cm) was obtained from plots These parasitic weeds threaten around 45 million hectare of African arable land (Sauerborn, 1991). Conclusion: The results showed that the highest production of sorghum forage and protein content was obtained at doses of fertilizer was 25 t ha –1 . Nitrogen suppresses some development stages of Striga such as stimulant production or activity (Cechin and Press, 1993). Applying inorganic fertilizer at reduced amount (micro-dose) and in situ rainwater harvesting using infiltration pits (IP) or tied ridges (TR) are low-input strategies to cope with these constraints. As depicted in Table 3, response of yield per panicle to nitrogen rates was significant (p<0.05). If there is no rain to activate the herbicide, escapes can occur where there is a bit of moisture in the soil to germinate grasses which come through the non-active barrier. Table 1 portrays the result of pre planting soil analysis. The highest value of the mentioned trait was registered at fertilizer rate of 150 and 100 kg N ha-1.
