“…Accordingly, the agronomic optimum rate of N for enhanced malting barley productivity was 54 kg N ha À1 for the Kofele and Chole districts sites regardless of preceding crops. Similar results of increased malting barley grain yield with increased N fertilization rates were also reported by several researchers including Halvorson 2014) and Kassie and Tesfaye ( 2019). Similarly, increased malting barley biomass yields with increased N fertilization rates were also reported based on several global studies including Halvorson and Reule (2007a,b) and Abeledo et al (2008).…”

“…Generally, N fertilization improved the seed weight of malting barley within ranges of 1-4 and 7-9% in Kofele and Chole districts, respectively compared to the unfertilized treatment (Figure 3). Increased malting barley kernel weight with increased N fertilizer rates was also reported in previous studies (e.g., McKenzie et al, 2005;O'Donovan et al, 2011;Upendra et al, 2013 andKassie andTesfaye, 2019). Similar to the effect of cropping sequence, the mean kernel weight of malting barley for the Chole (50.23 mg) sites (Figure 3b) was somewhat higher than the Kofele (48.99 mg) sites (Figure 3a), which could be attributed to the relatively higher initial phosphorous concentrations in the soil for the Chole (26.4 mg kg À1 ) sites compared to Kofele (13.33 mg kg À1 ) sites, and to its consequent positive impact on seed formation.…”

“…The lower the soil fertility, the greater was the effects of crop rotation and N fertilizer applications. Increased malting barley kernel protein concentrations with increased N fertilization rates have been documented by several studies including Halvorson and Reule (2007a,b) Agegnehu et al (2014) and Kassie and Tesfaye ( 2019).…”

“…Generally, the economic profitability agrees well with the agronomic results. Kassie and Tesfaye ( 2019) also reported a higher MRR of US$9.76 for every US$1.0 investment for the application of 48 kg N ha À1 for malting barley (cv Holker) production in Lemu-Bilbilo district in the southeastern highland of Ethiopia.…”

The growing demand for malt has generated interest for improving productivity through sustainable means such as cropping sequences with malting barley along with optimum nitrogen (N) fertilization. Cropping sequence has many benefits for optimum yield and quality, but knowledge of rotational effects of preceding crops on malting barley is still limited. Thus, this study was conducted to determine the effects of legume and non-legume preceding crops, and N fertilization on productivity and quality of malting barley grown the following year in two locations in the southeastern highland of Ethiopia. The experiment was split plot design with six preceding crops (fababean, Ethiopian mustard, potato, linseed, wheat and malting barley) as main plots and four levels of N (0, 18, 36 and 54 kg N ha À1 ) for the succeeding crop as split plot treatments with 3 replications. Malting barley grown after fababean, Ethiopian mustard and potato exhibited 13-16, 14-34 and 14%, respectively grain yield increments compared to growing malting barley after malting barley. Similarly, application of 36-54 kg N ha À1 gave 4-29 and 3-19% grain yield increments compared to the control (no N) and previous recommendation (18 kg N ha À1 ), respectively with no detrimental effect on kernel protein concentrations. Seeding malting barley at a rate of 54 kg N ha À1 gave 250-915% increase in economic benefit. Use of break crops other than barley and increasing the rate of N application from 18 to 54 kg ha À1 have been recommended to boost malting barley yield without surpassing the acceptable range of kernel protein concentrations, reduce costs of production, increase profitability and improve soil fertility to enhance long-term sustainability of the cropping system.

“…The higher N concentration with increasing level of N fertilization was due to enhanced supply of N to the crop. Similarly, Kassie and Tesfaye (2019) [5] , Yousif and Evans (2018) [11] , Singh et al (2012) [8] and Shafi et al (2011) [6] concluded that N concentration in grain and straw increased with increasing nitrogen levels in barley. Alghabari and Al-Solaimani (2015) [1] and Taalab et al (2015) [9] also observed a linear increase of grain nitrogen concentration with increasing nitrogen rates.…”

Due to scarcity of irrigation water in Haryana, the field experiments were conducted during rabi seasons of 2017-18 and 2018-19 at Hisar to study the influence of different varieties (BH902, BH 946, BH 885 and DWRB 101) and nitrogen levels (0, 30, 60 and 90 kg ha -1 ) on nutrient content and uptake in barley under saline water irrigation. Barley variety BH 902 recorded maximum N content in grain and straw (1.67 and 0.51 %, respectively) in comparison to BH 946, BH 885 and DWRB 101. Six rowed barley varieties BH 902 and BH 946 recorded significantly higher N, P and K uptake as compared to two rowed barley varieties BH 885 and DWRB 101. All the nitrogen levels significantly enhanced the N content in grain and straw as compared to control, whereas P and K content in grain and straw was not significantly influenced by different varieties and nitrogen levels. The N uptake by grains, straw and total N uptake increased significantly with each increment of nitrogen dose up to 90 kg ha -1 , while total P and K uptake was significantly increased only up to 60 kg ha -1 .

Soil fertility depletion has significantly reduced the yields of various crops in Ethiopia, mainly the yield of malt barley in the district. To address this issue, integrated applications of vermicompost and mineral nitrogen (N) fertilizers were tested. Therefore, this study aimed to evaluate the effects of vermicompost and mineral nitrogen fertilizers application on malt barley yield (Hordeum distichum L.), soil properties, and economic benefits. The experiment was arranged in a randomized complete block design with three replications. The treatments were nine in various combinations of vermicompost (VC) and N fertilizer (N): (69 kg N; 0.79 t VC + 58.65 kg N; 1.59 t VC + 48.30 kg N; 2.39 t VC + 37.95 kg N; 3.19 t VC + 27.60 kg N; 3.98 t VC + 17.25 kg N; 4.78 t VC + 6.90 kg N; 5.31 t VC ha−1 and control). The highest soil pH was recorded by applying 5.31 t of vermicompost ha−1 alone. The highest total nitrogen (0.34%), available phosphorus (15.58 mg kg−1), grain yield (4950 kg ha−1), and net benefit (4255.74 USD) were recorded from the application of 2.39 t VC plus 37.95 kg N, while the highest soil organic carbon (3.38%) and cation exchange capacity (26.17 cmol (+) kg−1) were recorded from 3.19 t VC plus 27.60 kg N ha−1 compared to the control. This study concludes that applying 2.39 t VC and 37.95 kg N ha−1 in combination improves soil fertility, malt barley yield, and economic benefits for smallholder farmers in the study district and adopts this in similar soil types and agroecologies.
