Abstract: Salvia hispanica is an important member of the Labiatae family and its role as health-promoting effect is attributed to it is rich source of phytoconstituents. The historic grain is becoming extremely trendy in modern food regime in numerous countries; the major proportion of α-linolenic acid makes chia the superb source of omega-3 fatty (about 65% of the oil content). Omega-3 fatty acid has been linked with a number of physiological roles in human body. Chia seed is a potent source of antioxidants with the presence of chlorogenic acid, myricetin, caffeic acid, quercetin, and kaempferol which are believed to have hepatic protective effects, cardiac, anti-ageing and anti-carcinogenic properties. It is also a great source of dietary fibre along with higher concentration of valuable unsaturated fatty acids, gluten free protein, minerals, and vitamin sand phenolic components. Other than this, seeds are an exceptional wellspring of polyphenols and cell fortifications, for instance, caffeic destructive, rosmarinic destructive, myricetin, quercetin and others. Today, chia has been destitute down in various domains of research. Researchers around the world have been investigating the upsides of chia seeds in the pharmaceutical, pharmaceutical, and sustenance industry. Chia oil today is one of the most noteworthy oils in the market. In this current review, the role of Salvia hispanica is summarized in the prevention and treatment of diseases via the regulation of various physiological and biological pathways.

Abstract: In this research caffeine content in coffee sample from Abe Dongoro, Sasiga, Gida Ayana and Sibu Sire of Wollega administrative zone of Ethiopia were determined using High Performance Liquid Chromatography (HPLC) and UV-Vis Spectrophotometry methods. Caffeine in aqueous extract of coffee samples was extracted with dichloromethane prior to analysis by UV-Vis spectrophotometry method and dichloromethane was evaporated from the extract and the extract was dissolved in water (HPLC grade) to determine caffeine contents in coffee samples using HPLC method. The linearity of the HPLC and UV-Vis spectrophotometry methods were R2 = 0.9999 and R2 = 0.9997 respectively. HPLC and UV-Vis spectrophotometry methods were found to be accurate with recoveries of 97.5% and 117.4%, respectively. Limits of detection (LOD) obtained were 0.148 mg/L for HPLC method and 0.284 mg/L for UV-Vis spectrophotometric method. The caffeine contents in coffee samples obtained using UV-Vis spectrophotometry method was 3.42, 2.638, 2.207 and 2.986 mg/L for Abe Dongoro, Gida Ayana, Sasiga and Sibu Sire coffee samples respectively. Similarly, using HPLC method the caffeine contents in coffee samples obtained was 1.871, 1.601, 1.307, 1.83 mg/L for Abe Dongoro, Gida Ayana, Sasiga and Sibu Sire coffee samples. There is a significant difference between the caffeine contents in coffee samples obtained by the two methods.

Abstract: The field trial was conducted during 2017 and 2018 main cropping season at the Bore Agricultural Research Centre which is located in Gudji Zones, of Southern Ethiopia to determine the effect of different application rates of nitrogen and phosphorus fertilizers on growth, yield and yield components of head cabbage and to identify their economically appropriate rates that maximize yield of head cabbage. The experiment was carried out to study cabbage variety Olsen to added N and P nutrients in respect to growth, yield and yield related parameters of the crop. The longest head initiation (90 days) and longest (140) days to maturity was attained in 294 kg ha-1 Nitrogen and 138 kg ha-1 phosphorus treatment, while shortest head initiation (64.33 days) was obtained in control treatment. The maximum plant height (26.4 cm) was recorded for the treatment T3P4 (235 +138 kag ha-1), while the lowest (16.9 cm) plant height was recorded from the T1P1 (control) treatment. Nutrient levels markedly influenced the diameter, height, head mass and yield of head cabbage. The maximum average head diameter (25.44 cm) and average height (27.33 cm) was recorded in treatment receiving 235 kg N and 82 kg P ha-1. Combined application of 235 kg N ha-1 with the 82 kg P ha-1 produced the highest (2356.67 g) untrimmed head weight of cabbage followed by second maximum (2133.33 g) untrimmed head weight with the rate of 235 kg N ha-1 with the 110 kg P ha-1 while the least (1120.67 g) untrimmed head weight was recorded for the control treatment. Combined application of 235 kg nitrogen and 82 kg phosphorus ha-1 (N3P2) recorded maximum (69.00 t) head yield without wrapper ha-1 and the lowest (27.66 t ha-1) was recorded by control treatment. The marginal rate of returns, which determines the acceptability of any treatments shows that treatments that received 235 kg N ha-1 in combination with 82 kg ha-1 of P yielded 43498% marginal revenue. Therefore, this combined nutrient application rates can be recommended in the research area and similar agro-ecologies since it is the most feasible rates for the producers because of its low cost of production and higher benefits.
