“…In Latvia, measurements of GHG emissions in the agricultural sector have been launched implemented in several directions. Firstly, research on GHG emission reduction measures and develops future os for GHG emissions in Latvia (Kreismane et al, 2016;Lēnerts et al, 2016 (Berzina et al, 018;Grinfelde et al, 2018;Jonova et al, 2018bJonova et al, , 2018aJonova, Ilgaza, & Grinfelde, 2017). Thirdly, field and ry studies are being carried out to analyse not only GHG emissions from soil, but also to determine the effect izers on GHG emissions (Eihe et al, 2019(Eihe et al, , 2020Frolova et al, 2017Grinfelde et al, 2019).…”

“…National task is set for the next years in Latvia to retain agricultural land for agricultural production, in order to efficiently manage approximately 2 million ha. The agricultural sector is an important source of nitric oxide (N<inf>2</inf>O. Secondly, experimental studies are carried out on farms where CH 4 measurements are carried out and solutions are sought to reduce CH 4 emissions in the livestock sector (Berzina et al, 2017(Berzina et al, , 2018Grinfelde et al, 2018;Jonova et al, 2018bJonova et al, , 2018aJonova, Ilgaza, & Grinfelde, 2017)to measure the amount of methane (CH4. Thirdly, field and laboratory studies are being carried out to analyse not only GHG emissions from soil, but also to determine the effect of fertilizers on GHG emissions (Eihe et al, 2019(Eihe et al, , 2020Frolova et al, 2017.…”

Agriculture is a source of three primary GHG: CO2, CH4 and N2O. In order to reduce agricultural GHG emissions, agricultural practices have to promote sustainable land management by helping to prevent soil erosion and creating the potential to increase soil carbon stock. Sustainable soil management includes reducing tillage and introducing legumes in crop rotation. The aim of the study is to identify the impacts of the soil tillage and the cultivated crops on formation of GHG emissions. The study site has 24 experimental fields where two types of soil tillage have been used and four crops where grown (wheat Triticum aestivum, rape Brassica napus, beans Vicia faba and barley Hordeum vulgare). Soil humidity, soil temperature and measurements of GHG emissions have been carried out during the plant vegetation period from 2018 to 2020. GHG emissions where measured using Picarro G2508. A total of 460 measurements of GHG emissions were made in 2018, 2019 and 2020. The minimum value of N2O emission is -19.5 g ha-1 day-1, but the maximum is 273.4 g ha-1 day-1. CH4 emission has a minimum value of -84.8 g ha-1 day-1, and a maximum of 514.1 g ha-1 day-1. The minimum value of CO2 emission is -13.0 kg ha-1 day-1, but maximum of 1026.7 kg ha-1 day-1. The results of CO2, CH4 and N2O emissions show a significant discrepancies between the arithmetic mean and the median values which indicates the observed extreme values. Kruskal-Wallis test showed statistically significant differences in GHG emissions by crop groups.

“…Jerusalem artichoke contains just around 10% of inulin, but using special technologies, the content of inulin can be increased up to 48.5-50.1% out of the dry weight [18,20,21]. The supplement containing prebiotic inulin which is used in this study is produced in Latvia at the University of Latvia Institute of Microbiology and Biotechnology.…”

Aim:The aim of the research was to evaluate the growth performance, to measure the amount of methane (CH4) and carbon dioxide (CO2) in calves’ rumen, and to compare the obtained results between the control group (CoG) and the experimental group (Pre12) which received the additional supplement of the prebiotic inulin.Materials and Methods:The research was conducted with ten Holstein Friesian (Bos taurus L.) crossbreed calves with an average age of 33±6 days. Calves were split into two groups: 5 calves that were fed with the control non-supplemented diet (CoG) and 5 calves that were fed with the same diet further supplemented with 12 g of flour of Jerusalem artichoke (Helianthus tuberosus L.) containing 6 g of prebiotic inulin per 0.5 kg of barley flour diet (Pre12). The duration of the experiment was 56 days. CH4 and CO2 were measured using cavity ringdown spectroscopy device Picarro G2508. The weight and samples from calves’ rumen were evaluated 3 times during the experimental period - on the 1st, 28th, and 56th days. Samples were obtained by puncturing the calf rumen.Results:The weight gain (kg) during the whole experimental period was higher in the Pre12 (65.8±6.57) compared to CoG (36.8±7.98) calves (p<0.001). The daily weight gain was also increased in the Pre12 (1.2±0.12) than CoG (0.7±0.14) calves (p<0.001). There was no difference in the levels of CH4 and CO2 produced in the rumen of CoG and Pre12 calves (p>0.05).Conclusion:The main results showed that the prebiotic inulin can promote weight gain in calves, without affecting the mean concentration of CH4 and CO2 in calves’ rumen.

Within the frame of the Nordic/Baltic public-private partnership 'PPP for pre-breeding in perennial ryegrass' various activities were performed, including assessment of L. perenne (Lp) genotypes under agro-ecological conditions of Latvia. This article summarizes the data obtained in two harvest years for 19 intermediate tetraploid (4x) Lp genotypes. In order to compare the results obtained in ryegrass with performance of grass interspecies hybrids (Fl), which become especially relevant in the recent years, two varieties, developed in Latvia -Lolium × boucheanum Kunth. 'Saikava' and × Festulolium 'Vizule' were included in the experiment. Various scores were performed, including evaluation of regrowth, intensity of culm development, sward cover, crown rust (Puccinia coronata) susceptibility, etc. The dry matter yield (DMY) and fodder quality were also determined. It can be concluded that the genotypes showed relatively good results in the first two harvest years. Wintering conditions were favourable. Despite the intensified drought and heat in the 1 st ley year, relatively high DMY, which ranged from 9.30 to 12.15 t ha -1 , for Lp were harvested in three cuts. In the 2 nd ley year, under more favourable humidity conditions, Lp in four cuts provided similar DMY, which ranged from 8.81 to 11.50 t ha -1 . If we compare the average DMY of Lp and Fl genotypes, it can be concluded that in the first two harvest years no significant differences were found, the average DMY was 10.30 and 10.64 t ha -1 , respectively. No significant differences were found between Lp and Fl in terms of forage quality.
