There are limited options for post grass control so scout heavy early and respond aggressively to escapes while they are small. Micro-dose fertilizer use with improved cereal varieties is practised, often complemented by application of manure. fertilizer dose. The major factors that account for this low yield are moisture stress, low soil fertility and pest damages. If the phosphorus level in the field is low, starter fertilizer is an excellent way to get … Table 1 portrays the result of pre planting soil analysis. Nitrogen remaining in the nodules and other plant tissue and in the soil after a legume crop provides N for succeeding crops through mineralization. seven single-cut forage sorghum genotypes (SPH 1822, SPV 2316, SPV 2387, SPV 2388, CSH 13, CSV 21F and CSV 30F) and three fertilizer levels viz. Top dressing: It is the application of manures and fertilizer… A combined soil sample was taken from the experimental site using auger for soil physical and chemical properties analysis. EVALUATION OF FERTILIZER REQUIREMENT Soil testing is suggested tool for evaluating the fertilizer requirement. The highest value of the mentioned trait was registered at fertilizer rate of 150 and 100 kg N ha-1. rainfall pattern more than 80-85% of the rain falling in the summer (between The Southwesterly monsoon winds bring rainfall However, though it was comparable statistically, ANUE tended to decline by 11.6% with increment of nitrogen application level from 100-150 kg N ha-1. Research Center (HARC) Sheraro research sub-site, from July up to October during J. Horticul.Ornam. Many grain sorghum varieties grow to only 5 feet tall, but sweet sorghum and broom corn plants can top 8 feet. 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. Bilal et al. Fertilizer Recommendations by Crops, Categorized (Crop codes in parentheses) I Field Crops 1. application on yield and yield components of sorghum in northern Ethiopia. application. Please check the Crop Watch Calendar for Upcoming Events! J.H. 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. Yield per panicle increased with increasing of nitrogen levels. A The organic matter of the area is very low (1.0%). One, in the seedling stage when chinch bugs are present because of poor control or too late control of grasses like volunteer wheat. with the application of nitrogen fertilizers. to the area during the summer mainly from June to October. The use of inorganic fertilizers to boost yields of sorghum has been found to increase growth performance, as well as the chemical properties of soil [ 15 ]. Microfertilizing, consisting of applying small amounts of mineral fertilizer to the planting hole or pocket, was tested in Mali. 1,100 for inorganic fertilizers . Nitrogen application at a rate of 150 kg N ha-1 gave the lowest numbers of Striga branches per plant (5.6). On the other hand, the lowest plant height (120.83 cm) was obtained from plots In infested areas, yield losses related with Striga damage are often significant, varying from 40-100% (Hess et al., 1996). In-furrow insecticides increased corn grain yields by as much as 1823 kg/ha. Field experiments were conducted in … Effect of nitrogen on Striga plant height, branching and count per plot: As depicted in the Table 5 and Fig. 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. 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 … Since 2014, subsidized fertilizer has decreased from nearly 11.8 million tons to 4.1 tons — a savings of 7.7 tons. Decrease in Striga plant height was observed with increased nitrogen level application. It is very important in either case to take a load out of the bin after filling to take the cone down (level the bin) and remove fines from the grain spreader out of the center of the bin. Highest responses of If you feel you have to part the residue, do so without moving soil. Grain yield, stover yield and harvest index (HI): Result of data analysis presented in Table 4 indicated that nitrogen application at different rates significantly (p<0.05) increased grain yield over control. • Fe and zinc are the micronutrient most likely to be deficient in Kansas for sorghum. Effect of nitrogen on Striga emergence: The result in Table 5 clearly indicates variation in nitrogen rates had no effect on Striga emergence (p>0.05). Grain sorghum grown after legume crops required minimal levels of P and K, especially when N fertilizer was added. Sorghum [Sorghum bicolor (L.) Moench] is an important food crop grown by subsistence farmers in Africa with little or no fertilizer. Results from a crop rotation study conducted by Paul Hay from 1994-2005. Fasil (2003) also reported very high and two season consistent response of Sorghum to inorganic fertilizers mainly nitrogen in Sheraro (the area where this study was conducted). Agronomic Nitrogen Use Efficiency (ANUE): The data in the Fig. Increasing nitrogen application from 50-100 and 150 kg N ha-1 increased ANUE by 59.2 and 53.8%, respectively. Map of the study area (Mechara Agricultural 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 . From the perspective of the whole sorghum growth and development process, the sorghum fertilizer requirement rule is less in the early period and … et al., 2003). Check out the sorghum soil management page for current University of Nebraska-Lincoln Extension recommendations for nitrogen, phosphorus, potassium, zinc, iron, and sulfur. Sorghum productivity in the world in general and in Ethiopia in particular is by far below its potential. fertility and nitrogen is an essential element for reversing this effect. leaf area index, panicle length, yield per panicle, 1000 grain weight, grain altitude of 970 m above sea level. fertilizer dollars in sorghum is from N and P. • Sulfur becoming an issue on some soils. 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. of four nitrogen fertilizer levels (0, 50, 100 and 150 kg ha-1). 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. 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. Sorghum is considered to be originated in Northern Africa or at the Egyptian-Sudanese border 5,000-8,000 years ago. Trifold Chinch Bug Plan: Chinch bugs are a threat to sorghum at three stages. dose at sowing and 1/2 dose at mid-vegetative, 1/2 dose at mid-vegetative and 1/2 dose at booting. Moreover, straw and grain samples were collected from each plot of central rows at harvest for nitrogen analysis following kjeldahl method. In general the positive effect of high dose of nitrogen on plant height could be due to the utilization of more nitrogen as nitrogen is an essential nutrient for growth. This result is in line with the findings of Poornima et al. and might be more possibly due to the direct effect of nitrogen for vegetative A field experiment was conducted to assess the effect of rates and time of nitrogen fertilizer application on yield and yield components of sorghum in northern Ethiopia. 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). (701) Canola Spring Type2. With good aeration you can keep the fans running and handle corn at 19-20%, but milo at 17-18% is about as high as you should go. Huskie, the newest herbicide registered in sorghum should be applied at 12.8 to 16 fl oz/acre with 0.25 to 1.0 lbs of atrazine, NIS 0.25% v/v or 0.5% v/v HSOC (high surfactant oil concentrate), and spray grade ammonium sulfate at the rate of 1 lb/acre to sorghum from 3-leaf to 12 inches tall. randomized complete block design with three replications. The significant increase in total nitrogen uptake at high N levels application could be attributed probably to increased availability of nitrogen and good root growth. Increase in plant height with increased nitrogen rates is not unexpected Keywords: Biomass WUE, crop evapotranspiration (ET c), Grain yield WUE, P-Fertilizer effect, sorghum … Similarly, Agbobli (1991) reported application rates greater than 60 kg N ha-1 reduced number of emerged Striga asiatica in maize crop. 2008 main growing season. 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. Grass killers for sorghum are shoot absorbed. 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 . June and October) season. Mustafa and Abdelmagid (1982) has also shown that application of nitrogen fertilizer increased plant height in sorghum. Band application of phosphorus fertilizer on low phosphorus soils is suggested for corn and grain sorghum to maximize fertilizer use efficiency. It is evident from table below that nitrogen fertilization had increased the leaf area index compared to control plots. The lowest yield per panicle was recorded from nitrogen untreated plots which was statistically comparable with 50 kg N ha-1 application. 1 indicates that, Agronomic Nitrogen Use Efficiency (ANUE) of sorghum was affected by nitrogen levels. 1). Spraying the last part of the herbicide behind the planter and/or using glyphosate behind the planter extends the weed control program and ensures a clean field at planting without using tillage to dry the soil and plant more weed seed. Increasing seed rate significantly decreased the … Sorghum is cultivated on Vertisols in the Ethiopian Highlands. 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. Moench) in Sudano-Sahelian zone. This provides very good staple food in highly populated Climate Requirement for Sorghum Production:- Sorghum crop can be grown in drought areas as it can tolerate high temperature and drought conditions. Sorghum (Sorghum bicolor L. Moench) is an important food crop in Ethiopian. Because micro dosing reduces the amount of fertilizer used, it helps to decrease nitrate levels in groundwater and surface water. Lowest Striga plant height (31.5 cm) was recorded with 100 kg N ha-1 application, though it was non-significant with 150 kg N ha-1 application rate. The least total nitrogen uptake (46 kg N ha-1) was at the control and the highest (75 kg N ha-1) was at 150 kg N ha-1. Keep weeds under control until developing sorghum plants are big enough to dominate their space. Grain yield was recorded from the harvest of three central rows in each plot and was converted into kg ha-1 accordingly. Many times these are top performers and height is not a real issue with today's combines and is not closely related to stalk rot or standability. (2008) and Akdeniz et al. Some parts of this site work best with JavaScript enabled. count/plot were also reduced significantly (p<0.05) with 150 kg N ha-1 So a solid before planting program is the best. Nitrogen application at a rate of 150 kg ha-1 recorded the highest plant height (137.04 cm). Study area: The study was conducted in Northern Ethiopia, Humera Agricultural The highest yield in sorghum protein content (11.13%) contained in the fertilizer treatment cow manure at a dose of 25 t ha –1. Sites where nutrient deficiencies in corn and grain sorghum are identified by Cooperative Extension personnel, growers, etc., will be examined and soil and plant samples collected. The crop was drilled in naturally Striga infested soils maintaining 75 and 20 cm spacing between rows and plants, respectively, in 3.75 by 4 m (15 m2) plot area. mm with good distribution, whereas, average annual temperature vary with the Pre planting soil analysis illustrates that the textural class of the soil is clay (52.36%) with soil pH of 7.4. In Northern Ethiopia, the average yield of sorghum is even below the national yield average (CSA., 2008). Different authors also reported the negative effect of nitrogen on Striga growth and development. All the experimental units where receiving all the other management practices equally and properly. 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. Nitrogen application also affected number of Striga branches per plant significantly (p<0.05) (Table 5). Three, after heading when the second generation flies into the milo field and sets up housekeeping. 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). 2). It is a short duration crop of 110-130 days as compared to 12-18 months in sugarcane. 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. 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. Huskie, the newest herbicide registered in sorghum should be applied at 12.8 to 16 fl oz/acre with 0.25 to 1.0 lbs of atrazine, NIS 0.25% v/v or 0.5% v/v HSOC (high surfactant oil concentrate), and spray grade ammonium sulfate at 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. Among all nitrogen levels, 150 kg N ha-1 application rate gave the highest stover yield (4851.85 kg ha-1) while the lowest stover yield (3787.04 kg ha-1) was obtained in the control treatments, though it was statistically not different with the other two N rates. Residue also shades the soil and reduces evaporation loss from the soil surface. Split application of nitrogen at various stages like sowing, 30 DAS, boot leaf stage and at grain … Crop residue does this in two ways. Leaf area index increases were 5.0, 9.5 and 20.8% over the control at 50, 100 and 150 kg ha-1 nitrogen fertilizations, respectively. Mumera (1983) recorded a 64% reduction in S. hermonthica emergence in maize using 39 kg N ha-1. (001) Corn (for Grain) Dryland4. The shares of irrigated and rainfed sorghum in total fertilizer consumption were 0.5 and 2.4 percent, respectively. • N, P, Zn, (and K) have reliable soil tests to measure nutrient availability and predict fertilizer needs. . Modern grain sorghum hybrids have the ability to yield much more than what the casual grain sorghum grower usually realizes. Milo needs 1.1 pounds of nitrogen per bushel for top economic production. Poor soil fertility, mainly soils low in nitrogen and organic matter which is a typical characteristics of most soils in the Northern part of Ethiopia, not only give poor crop yields but also contribute to increased Striga germination, increased flowering and seed production and prolonged Striga seed viability in the soil (Shank, 1996). Levels of nitrogen fertilizer from 110-170 kg N ha-1 were reported to control Striga hermonthica in sorghum (Showemimo, 2007). Manures and Fertilizers in Sorghum Production:-Proper application of manure and fertilizers on time ensures good crop growth and high yield. are root hemi-parasitic weeds of tropical cereal and legume crops including maize, sorghum, millet, rice, sugarcane and cowpea causing significant losses to food crops in Africa and Asia. Soils with a ranges from 27-30°C. 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. As depicted in Table 3, response of yield per panicle to nitrogen rates was significant (p<0.05). Crop Spacing (cm) Micro dose (g/hole) 0 0.3 0.6 0.9 Equivalent dose (kg/ha) Sorghum 60 × … also reported that plant height increased progressively up to harvest over control Kumar et al., (2010) reported that the increase in productivity of sorghum could be brought out both by genetic improvement as well as associated nutrient management The grain yield improved with increased levels of nitrogen fertilizer application. showed that application of N-fertilizer significantly increased plant height, respectable yields under unfavorable growing situations has made it a well-liked Check out the sorghum soil management page for current University of Nebraska-Lincoln Extension recommendations for nitrogen, phosphorus, potassium, zinc, iron, and sulfur. Green and dry fodder yield increased significantly with increase in … Mustafa and Moreover, nitrogenous fertilizer may enhance the degree of resistance shown by resistant sorghum cultivars (Ramaiah and Parker, 1982). 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). Results 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. The agro-ecology of the area is hot to warm semi arid low land plains with an Water Preparation. Sorghum hermonthica infestation is a result of declining soil fertility which weakens the host plant to Striga attack. This means application of nitrogen did not affect the speed of Striga germination at all levels. (C01) Corn (for Grain) Irrigated 200 bu/a consisted of four rates of nitrogen (23, 46, 69 and 92 kg N ha-1) and three time of N application (1/2. Abdelmagid (1982) has also shown that application of nitrogen fertilizer 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. In agreement with the present finding Sinebo and Drennan (2003), reported reduced height and weight of the parasite weed S. hermonthica with nitrogen application. Striga spp. In areas where sorghum is commonly grown yields of more than 3000 to 4000 kg ha-1 are obtained under better conditions dropping down to 300 to 1000 kg ha-1 as moisture, soil fertility and other biotic and abiotic factors become limiting (ICRISAT., 1995). Declining soil fertility and limited farmer access to inorganic fertilizer frequently cause sub-optimal grain yields throughout sub-Saharan Africa. Table 5 also shows that Striga plants grown in plots amended with 50 kg N ha-1 and the control gave significantly more branches per plants than high dose of nitrogen application (150 kg N ha-1). ... Sweet sorghum has less water and fertilizer requirements and hence lower cost of . Phosphorus starter fertilizer increased yields by 2075 kg/ha. Stay alert and do the best you can to choose treatment options for this troublesome pest. Moench) in Sudano-Sahelian zone. Treatments in August most often kill the greenbugs after the damage has been done. of nitrogen on plant height could be due to the utilization of more nitrogen Adequate application of nitrogen fertilizer increases plant vigor and dry matter weight (shoot and root) and according to Showemimo (2007) good plant vigor and high dry matter weight are important criteria for selecting sorghum that are resistant/tolerant to Striga threat. (2000) The lowest value for panicle length was obtained from the untreated plot (17.03 cm) which was also significantly at par with 50 kg N ha-1 application. corn, sorghum and wheat. 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). On the other hand, the lowest 1000 grain weight was recorded from the control and plots receiving 50 kg N ha-1. 14° 24 0 North latitudes and 37° 56 0 East longitudes. There was a significant (p<0.05) effect of nitrogen levels on stover yield (Table 4). With regard to fertilizer doses, application of higher fertilizer dose of 125% RDF increases the crude protein content at first (8.51%), second (8.48%) and third cut (8.31%) of forage sorghum (Table 2 and figure 3) . Analysis of variance revealed significant (p<0.05) effect of nitrogen application at various levels on thousand grain weight of grain sorghum. Increased application of nitrogen results incoherent augmentation of ANUE (Fig. The soil type of the area is Euthric Vertisol. The present finding could be in concurrence with Ogborn (1987) which realized reduction in the number of flowering S. hermonthica with application of 155 kg N ha-1 in sorghum crop. 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. Ideal dose of Nitrogen (‘N’): under high yielding and rain fed conditions or local varieties of irrigated crop: 70 to 80 kg /ha; For Irrigated high yielding varieties: 120 to 150 kg/ha Now, with the micro dose technology, he can harvest up to 1.2 tons per hectare. 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). Sorghum planted under cool soil conditions can show a significant early growth response when starter fertilizer is properly applied. 2. Nitrogen uptake: The ANOVA results for mean nitrogen uptake revealed significant difference (p<0.05) of nitrogen levels. yield, stover yield and harvest index over the control. 2,100, in which Rs. Ouedrago previously harvested only 0.7 tons of crops per hectare on his millet and sorghum farm. Plants 012 Figure 1. A farmer is wise to consider the value of this N when determining his N fertilizer program for successive crops such as cornwheat. 3). Sorghum cultivars are known to vary in their response to fertilizers. 105 Ag. Results of analysis of variance on leaf area index revealed that nitrogen levels showed significant difference (p<0.05). One meter and 1.5 m distances were maintained among plots within replication and between replications, respectively. application under natural Striga infestation. It was found that 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. Hence integration organic and inorganic fertilizer will sustain the soil heath and improve the cane yield of the sweet sorghum crop. It contains B-vitamins like thiamin and riboflavin. Since 2014, subsidized fertilizer has decreased from nearly 11.8 million tons to 4.1 tons — a savings of 7.7 tons.
