fertilizer dollars in sorghum is from N and P. • Sulfur becoming an issue on some soils. 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. Sorghum usually grows poorly on sandy soils, except where a heavy textured sub-soil is present. This means application of nitrogen did not affect the speed of Striga germination at all levels. 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. 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 Sorghum, with the majority of domestic production used for household consumption/fodder. This study was undertaken with the objective of evaluating micro-dosing of mineral fertilizer combined with seed priming in sorghum, groundnut, sesame, and cowpea. Effect of nitrogen levels on Sorghum nitrogen use efficiency was also reported by Amiri et al. 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. Milo needs 1.1 pounds of nitrogen per bushel for top economic production. Because micro dosing reduces the amount of fertilizer used, it helps to decrease nitrate levels in groundwater and surface water. The lowest yield per panicle was recorded from nitrogen untreated plots which was statistically comparable with 50 kg N ha-1 application. 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). Productivity of sorghum is limited by soil fertility. 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 highest harvest index (0.34) was obtained with 100 kg N ha-1 application which was statistically not different from 150 kg ha-1 nitrogen application rate. (1974): Data on Striga days to first emergence, branch per plant, plant height and Striga count per plot were recorded. Moench) in Sudano-Sahelian zone. Association of Fertilizer and Phosphate Chemists Check Sample Program. Fertilizer use by crop 25 Paddy rice 27 Wheat 27 Sorghum 27 Pearl millet 27 Maize 28 Pigeon pea 28 Rapeseed and mustard 28 Groundnut 29 Sugar cane 29 Cotton 29 … Grain sorghum grown after legume crops required minimal levels of P and K, especially when N fertilizer was added. 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). • Fe and zinc are the micronutrient most likely to be deficient in Kansas for sorghum. Data on sorghum growth parameters and yield components as well as some Striga reported to have significant negative effect on plant height (Olupot Ashebir (2005) also reported increasing levels of N from 0-69 kg N ha-1 resulted in a consistent increase in uptake of N by rice plants at the mid-flowering stage. randomized complete block design with three replications. Sorghum productivity in the world in general and in Ethiopia in particular is by far below its potential. This variation in stover yield might be due to the variation in plant height as well as leaf area. 1,100 for inorganic fertilizers . Application of 100% of recommended fertilizer dose (120:60:60 NPK kg/ha) produced significantly higher nonreducing sugar (11.10%), total sugars (12.07%) and commercial cane sugars (5.34%) and lower reducing sugars (1.31 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. 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. Moench) in Sudano-Sahelian zone. enhance sorghum yield and water use in low-rainfall cropping system and drought prone environment. Abdelmagid (1982) has also shown that application of nitrogen fertilizer An experiment was conducted in the Gumara-Maksegnit watershed in 2013 and 2014 to assess the effect of rate and timing of nitrogen fertilizer application on the possibility to shorten the maturity period and to improve the productivity of sorghum. 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. 1,000 for farmyard manure and Rs. 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. Please click here for information on a no-till sorghum starter fertilizer study. 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. J.H. The ratio of nitrogen, phosphorus and potassium is 10.51.2. In Northern Ethiopia, the average yield of sorghum is even below the national yield average (CSA., 2008). Sorghum is known for being nutrient-use efficient and managed with lower fertilizer rates compared to maize and rice, but yields can be increased with adequate fertilizer applications [11, 14]. 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. Some parts of this site work best with JavaScript enabled. to the area during the summer mainly from June to October. Don't be afraid of taller hybrids. application under natural Striga infestation. 2008). Please check the Crop Watch Calendar for Upcoming Events! rainfall pattern more than 80-85% of the rain falling in the summer (between 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). … High dose of nitrogen fertilizer application also affected Striga count per plot significantly (Table 5 and Fig. Sorghum is more tolerant of alkaline salts than other grain crops and can therefore be successfully cultivated on soils with a pH (KCl) between 5.5 and 8.5. The average annual rainfall of the area is about 1000 This observation collaborates with that of Regassa (2005) who found increasing the levels of applied inorganic nitrogen fertilizer from 0 to 30.75 N ha-1 increased N uptakes by the whole plant from 171.2 to 245.3 kg N ha-1. Results Table 1 portrays the result of pre planting soil analysis. 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. altitude of 970 m above sea level. growth parameters were recorded at their respective growth stages. 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. 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. Grass killers for sorghum are shoot absorbed. 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. The organic matter of the area is very low (1.0%). 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). Falls, S.A. Siegel, in Encyclopedia of Analytical Science (Second Edition), 2005. In all management decisions including harvest, the milo producer who treats it a first class crop is going to be more successful. 2). Mustafa and Abdelmagid (1982) has also shown that application of nitrogen fertilizer increased plant height in sorghum. 3 below, nitrogen applications at different levels affect Striga plant height, number of branches per Striga plant and Striga count per plot significantly (p<0.05). Declining soil fertility and low rainfall are key constraints to crop production and are threatening food security in semi-arid areas. 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. Benth is the most tenacious, prolific and destructive 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. It has to be done before the cropping season well in advance so as to ascertain the native fertility of the soil and to recommend the correct dose of fertilizer which will reduce the fertilizer cost. This study was undertaken with the objective of evaluating micro-dosing of mineral fertilizer combined with seed priming in sorghum, groundnut, sesame, and cowpea. Three nitrogen levels (0, 75 and 150 kg ha-1) were applied in three grain sorghum cultivars in a Turkish experiment (Güller et al. 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. One meter and 1.5 m distances were maintained among plots within replication and between replications, respectively. (2014). Stay alert and do the best you can to choose treatment options for this troublesome pest. Soils with a Keywords: Biomass WUE, crop evapotranspiration (ET c), Grain yield WUE, P-Fertilizer effect, sorghum … Highest responses of In drought alleviation study on rabi sorghum by nutrients and PGR showed that recommended dose of fertilizer @ 2 ml /l at 30, 60, and at 90days after sowing has given higher yield. https://scialert.net/abstract/?doi=ijar.2015.14.23, Maximum leaf width (cm)xMaximum leaf length (cm)x0.747. 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. These parasitic weeds threaten around 45 million hectare of African arable land (Sauerborn, 1991). So a solid before planting program is the best. Sorghum leaf area index was calculated using the formula developed by Krishnamurthy et al. June and October) season. consisted of four rates of nitrogen (23, 46, 69 and 92 kg N ha-1) and three time of N application (1/2. This is not the way those choices should be made. Check out the sorghum soil management page for current University of Nebraska-Lincoln Extension recommendations for nitrogen, phosphorus, potassium, zinc, iron, and sulfur. 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 . Effect of spacing and fertilizer dose on growth and yield of potato (Solanum tuberosum L) Gudane variety at West Hararghe, Eastern Ethiopia Int. That translates to about 67 pounds of fertilizer for every 2.5 acres. also reported that plant height increased progressively up to harvest over control 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). Yield per panicle increased with increasing of nitrogen levels. 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. Increasing nitrogen application from 50-100 and 150 kg N ha-1 increased ANUE by 59.2 and 53.8%, respectively. Nitrogen suppresses some development stages of Striga such as stimulant production or activity (Cechin and Press, 1993). 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). 2008 main growing season. 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. Fertilizer dose/ha N:P:K :: 100:50:50 kg (50% N with all P and K at the time of sowing and remaining . Maximum panicle length was recorded in plot receiving 150 kg ha-1 nitrogen application (21.25 cm) which was statistically similar with 100 N kg ha-1 applications which produced 20.93 cm panicle length. 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. count/plot were also reduced significantly (p<0.05) with 150 kg N ha-1 It eliminates the moisture lost from every tillage operation which amounts to one-fourth inch to one inch depending on timing and depth. It provides good antioxidants. of four nitrogen fertilizer levels (0, 50, 100 and 150 kg ha-1). Data collection: At harvest, random sample of ten plants were taken from each experimental units and plant height, leaf area index (cm), panicle length, yield per panicle and thousand seed weight were determined. 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). 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. Farm productivity is also at risk from extreme weather and future climate change. The shares of irrigated and rainfed sorghum in total fertilizer consumption were 0.5 and 2.4 percent, respectively.
