In the years 2007-2009, pot experiments on spring barley were carried out in greenhouse of Institute of Soil Science and Plant Cultivation-State Research Institute in Puławy, using the Mitscherlich pots. The following cultivars were compared: 'Basza', 'Conchita', 'Skarb', and 'Xanadu' in terms of their response to 3 levels of nitrogen fertilization (NH 4 NO 3): 1, 2 and 3 g N / pot. Doses of 1 and 2 g N / pot was divided into two parts: 60% before sowing + 40% at the end of tillering, and the dose of 3 g N / pot was divided into three parts: 60% before sowing + 25% at the end of tillering + 15% before heading. Studied spring barley cultivars varied by grain yield size, grain yield structure traits and response to nitrogen doses. Cultivars 'Conchita' and 'Xanadu' had the higher grain yield and greater number of spikes per pot compared to 'Basha' and 'Skarb'. Cv. 'Skarb' was characterized by higher total dietary fibre and insoluble dietary fibre contents in grains than other cultivars. Cv. 'Xanadu' was characterized by the highest soluble dietary fibre content. 'Conchita' cultivar showed a higher (1-3) (1-4)-β-D-glucan content in the grain than other cultivars. With the increase of nitrogen levels to 3 g N/pot, there was obtained significant increase in grain yield and number of spikes per pot in all spring barley cultivars, but the decrease of 1000 kernel weight. Comparing to other cultivars, the highest yielding cultivars 'Conchita' and 'Xanadu' showed greater percentage increases in grain yield and number of spikes per pot under the influence of increasing nitrogen doses to 3 g N / pot. At 2 and 3 g N/pot doses, the highest dietary fibre and soluble beta-glucan contents in spring barley grains was stated in comparison with a dose of 1 g N/pot. With the increase of nitrogen dose to 3 g N/ pot, there was showed significant increase in protein content in grain of all cultivars. Total dietary fibre, insoluble dietary fibre, and ash content in the grain of spring barley cultivars were not dependent on the nitrogen fertilization doses.
Effects of Cultivar and Nitrogen Dose on Grain Eight in Romanian Winter Barley
Romanian Agricultural Research
During 2014-2016 at National Agricultural Research and Development Institute Fundulea three yield trials with winter barley cultivars under three levels of nitrogen fertilization were performed. The objective of this study was the evaluation of Romanian winter six and two row barley cultivars across three years, in order to analyse the effects of cultivar and fertilizer dose on yield and grain weight. As the main source of variation, the nitrogen level influenced significant the grain yield, which registered a progressive increase according to nitrogen dose, while the grain weight decreased from the second to third nitrogen level. Influence of grain weight on yield was different and much stronger in a few cases, comparing winter six row with two row varieties and their reaction to the nitrogen dose. Variations in grain weight were related to the number of row/spike and at the three levels of nitrogen fertilization were highly correlated (r = 0.93*** and 0.85***). The most productive...

In order to investigate the effect of split application of nitrogen fertilizer and nitrogen level on the yield and yield components of barley, a split plot experiment in the form of randomized complete block design with four replications was carried out in the town of Vis in 2013-2014. The treatments included three levels of nitrogen (50, 90, 130kg/ha) in the main plots and split application of nitrogen (S1: Planting stage = 50%, stem elongation stage = 50%, S2: planting stage = 25%, stem elongation stage = 50%, reproduction stage = 25%, S3: planting stage = 25%, stem elongation stage = 75%) in the sub plots. The results showed that different levels of nitrogen had a significant effect on grain yield, number of spikes per area unit, number of grains per spike, and 1000-grain weight. The highest grain yield by 480.38 kg/ha and also the highest number of grains per spike, number of spikes per area unit and 1000-grain weight belonged to the treatment with130 kgNha-1. The lowest grain y...
Production characteristics of different malting barley genotypes in intensive nitrogen fertilization
Genetika, 2010
Two-year trials have been conducted in Technological Research Center in Zajecar. Research objects were six malting barley genotypes. The experimental crop was top dressed with the following amounts of nitrogen: 40, 60, 80 and 100 kg ha-1. The control variant was not top dressed. The obtained results showed that the genotypes reacted significantly to the increased amounts of nitrogen by changing their production characteristics and seed quality. In addition, the genotypes demonstrated certain varietal differences. A new genotype, Premijum, was highest yielding and it had the lowest total proteins in the grain. The genotype NS-525 had the highest 1000-grain weight (46.8 g). The effect of nitrogen on the studied characteristics depended on N quantity applied. Increasing amounts of nitrogen decrease positive effects on spike length, number of grains per spike, 1000-grain weight and yield. However, the protein content in grain kept increasing to the highest nitrogen dose, which lowered t...

In small-plot experiments established in 2001-2004 we studied the eff ect of the chemical composition of the plant dry matter of spring barley, varieties Kompakt and Jersey, on grain yields. A re la tive ly strong correlation was confi rmed between the chemical composition of the plant dry matter and yields. The correlation was most intensive in the case of nitrogen (r = 0.536), phosphorus (r = 0.503), magnesium (r = 0.464) and sulphur (r = 0.431) at the beginning of shooting (DC 30); in the case of potassium (r = 0.557) at the beginning of tillering (DC 23) and calcium (r = 0.530) during ear formation (DC 55). A relatively strong correlation remained from the beginning of tillering to the beginning of ear formation and later decreased. The weather conditions of the year and variety signifi cantly affected grain yields and also the previous crop was important. Grain yields of the variety Kompakt were statistically signifi cantly lower than of the variety Jersey (6.02 t. ha −1 and 6.45 t. ha −1 , respectively). The yields of barley grown a er sugar-beet were the highest (6.30-6.79 t. ha −1); the grain yields of barley a er maize decreased by 9.1-9.7 %. Higher grain yields of the Jersey variety resulted in levels of N-substances (11.35 %) lower than in the Kompakt variety (11.35 % and 11.60 %, resp.). No correlation was discovered between the nitrogen level in the plant dry matter during vegetation and the content of N-substances in barley grain.
Response of Dual Purpose Barley to Rates and Methods of Nitrogen Application
2012
In winter months the forage availability for livestock reduces very much, thus barley can be used as dual purpose crop. In the present study the influence of different levels and methods of nitrogen application were tested against the dual purpose barley. The experiments were conducted at Botanical Garden-Azakhel, University of Peshawar during 2010 by using RCB design with split plot arrangement. Different nitrogen levels (40 kg ha -1 , 80 kg ha -1 and 120 kg ha -1 ) were used. 40 kg ha -1 N showed minimum days to emergence, maximum spike m -2 and 1000 grains weight. 80 kg ha -1 N yielded maximum fresh and dry biomass, grains spike -1 and minimum days to spike while 120 kg ha -1 N showed maximum emergence m -2 , tillers plant -1 , leaves plant -1 , tillers m -2 , plant height and minimum days to maturity. N levels were applied either at once or divided in two and three equal doses. Nitrogen applied at once showed minimum days to emergence and maximum plant height while N applied in ...

The aim of the study was to evaluate the yield and grain quality (1000 kernel weight, test weight, crude protein, starch, b-glucans, total phenolic content, antiradical scavenging activity and a-tocopherol content) variation of three hulless spring barley (Hordeum vulgare L.) genotypes under different levels of N, in relation to weather characteristics. The field experiments were carried out at the State Stende Cereal Breeding Institute. Three hulless barley genotypes 'Kornelija'; 'ST 1165'; ST 1185 ST ' were studied during two years (2011 ST and 2012 using three levels of nitrogen (N80; N80+40; N80+80) by split application at the end of the tillering stage. The effects of genotype, N treatment and genotype by N treatment interaction contribute the variation in yield and grain quality traits for hulless barley genotypes. There were considerable differences between crop years in response of hulless genotypes to top-dressing N, with significantly (P < 0.05) higher grain yield, 1000 kernel weight, test weight, starch and b-glucans in the growing season of 2012, when rainfall was optimal at the tillering and stem-elongation growth stages. In 2012, a significant (P < 0.05) response to top-dressing N was recorded for grain yield and 1000 kernel weight (at rate N120), crude protein, starch and b-glucans (at rate N160). The maximum values of total phenolic content, antiradical scavenging activity (in 2011) and -tocopherol content (in 2012) were obtained with application of 160 kg N ha -1 . Hulless line '1185' gave the highest grain yield, starch, a-tocopherol content and radical scavenging activity, but variety 'Kornelija' formed significantly higher TKW, crude protein and b-glucans content.

SUMMARYField experiments were carried out on six sites in eastern Scotland between 1987 and 1989 to determine the effect of nitrogen on the yield, N uptake and grain N concentration of spring barley grown for malting. The effects of fertilizer applications at rates from 0 to 150 kg N ha-1 and the timing of application were studied, using three fertilizer forms: calcium nitrate, ammonium sulphate and ammonium nitrate. Calcium nitrate applications significantly increased grain N concentrations (P < 0·05), and grain yields (P < 0·01 and 0·05) at two sites, above the values obtained with the other fertilizers, but there was no effect at the other sites. Split applications of calcium nitrate increased yields above those from single applications in some treatments at two sites. At low rates, recovery of 15N-labelled fertilizer was greatest when applied as calcium nitrate. Recovery fell at higher rates in calcium nitrate treatments, but rose in ammonium sulphate treatments. Uptake of...

A study was carried out at Lacombe, Alberta, to develop baseline information on nitrogen recovery, utilization efficiency, and agronomic performance of spring barley. This information may enable us to understand where the inefficiencies of N nutrition may lay and determine strategies to improve nitrogen use efficiency (NUE). Three divergent cultivars, "Manley" (two-rowed, tall, late maturing), "Noble" (six-rowed, mid-height, intermediate maturing), and "Tukwa" (six-rowed, semidwarf, early maturing), were grown under low (0 kg ha −1 ), moderate (50 kg ha −1 ) and high (100 kg ha −1 ) rates of applied N fertilization. Both N recovery and utilization efficiency decreased with the increase in rate of applied N fertilizer, and NUE declined from 45 kg kg −1 N under the low N treatment to 33 kg kg −1 N under the moderate treatment and 24 kg kg −1 N under the high N treatment. The test cultivars were comparable in N uptake, but Tukwa and Noble were more efficient in their utilization of the N taken up than Manley, particularly under high N. Subsequently, while grain yield of Tukwa and Noble had increased linearly with rate of N fertilizer, the grain yield of Manley showed a declining trend under high N. This implies that, where a high input condition is targeted, improvement in N utilization efficiency may need to be given due consideration.
Yield and Economics of Dual Purpose Barley as Influenced by Various Nitrogen Dose and Seed Rate
International Journal of Environment and Climate Change
A field experiment was carried out during Rabi season 2019-20 at wheat and barley section research area of CCS Haryana Agricultural University, Hisar. The experiment was comprised of three nitrogen doses (N1-60, N2-75 and N3- 90 kg N/ha) as main plot treatments and four seed rates (S1- 87.5, S2- 100, S3- 112.5 and S4-125.0 kg/ha) as sub plot treatments. With four replications, experiment was laid out in split plot design. Based on the research investigation, it was found that nitrogen dose and seed rate both had significantly influenced the yield attributes and yield of dual purpose barley Among nitrogen doses, 90 kg/ha being at par with 75 kg/ha recorded significantly higher grain yield (4895 kg/ha), biological yield (12220 kg/ha) and green fodder yield (3706 kg/ha) which were 9.7, 12.0 and 15.1 percent higher than nitrogen dose of 60 kg/ha, respectively due to higher yield attributes i.e. number of effective tillers (85.08), number of grains per spike (44.15), number of spikele...
