Abstract: Malting barley is an important crop in the world due to its high nutritional value that imparts great benefits to health. The aim of this study was to evaluate the proximate analysis and energy value of five varieties of barley malting of Mexican origin. Results showed that malting barley varieties have on average high amounts of total carbohydrates (76.84%), protein (12.47%), fiber (5.65%), fat (2.67%), ash (2.36%), and moisture (10.34%) and provide lots of energy to humans. Although the five varieties have the same nutrients, each variety stands out for its particular characteristics. The Esperanza variety had a higher value of carbohydrates, considering it important for nutrition and the malting industry. The Esmeralda variety showed high protein content; this parameter is significant for the feed industry and human nutrition. Armida is the variety with the highest fat content and at the same time provides greater amount of energy. The varieties with higher fiber content and ash were Adabella and Alina, respectively.

Abstract: In the present work we investigated the banana peels (Musa cavendishii) of organic silk variety from Pachacamac (Lurín, Lima) for being waste contaminants without use that avoid the damage to the environment. The qualitative presence of polyphenols and flavonoids was determined by phytochemical marching developed in ethanol extract of banana peels. Using thin layer chromatography on an analytical and preparative scale and rapid column chromatography, it was possible to separate nine soluble fractions in methanol and five soluble fractions in double distilled water as well as their respective Rf values; and by UV-visible spectrophotometry were elucidated nine structures of methanol soluble flavones (5,7-dihydroxy-4'-methoxyflavone, 4',5,6,7-tetrahydroxyflavone, 5,7-dihydroxy-6-methoxyflavone, 4',5,7,8-tetrahydroxyflavone; 5,7,8-trihydroxyflavone, 4'5,7-trihydroxyflavone; 5,6-dihydroxy-7-methoxyflavone, 5,6,7-trihydroxy-4'-methoxyflavone and 5,7-dihydroxy-4',6-dimethoxyflavone) and two flavones that were in double distilled water soluble (5,6,7-trihydroxyflavone, 5,6,7-trihydroxy-4'-methoxyflavone); in order to contributing to the study of the components of the organic banana peels and also to the environmental health.

Abstract: Seasonal food shortage is amongst the principal problems of farmers in mid-altitude areas of Southern Ethiopia. Taro and sweet potato are important part of food security packages in some of the world’s poorest nations. Taro is grown over a wide range of environments from 1,300-2,300m.a.s.l.; mostly by the resource poor farmers and the drought area. Its compatibility with various types of limited in put farming systems (versatility) and reliability under conditions such as drought, high rain fall, disease resistance and low soil fertility have made it attractive crop to farmers. There is no recommended fertilizer rate of taros so far demonstrated and popularized to farmers, and hence this pre extension demonstration of fertilizer rate in Boloso-1 was carried out to develop high yielding taro for the area. The research was carried out in Boloso sore woreda of Wolaita zone and two kebeles were selected which are Dubo and GaraGodo respectively in 2018. There were significant difference exists among the urea applied and non applied Boloso-1 and Boloso-1 with urea application is recommended in the Boloso sore and in similar agro ecology. From the results of the treatment it was observed that farmers show great interest towards the Boloso-1 with urea application on top of the Boloso-1 applied without urea.

Abstract: This study was conducted to estimate the concentrations of 8 trace elements including (Mn, Fe, Cu, Zn, Ni, Ar, Cr, and Pb) and 4 anti-nutritional factors including (saponins, oxalates, phytate, and cyanogenic glycosides) in leaves and stems from Moringa oleifera. The concentrations in samples analyzed were found to be in the range of 0.88-1.88 mg/kg for Mn, 11.95-25.25 mg/kg for Fe, 0.35-1.22 mg/kg for Cu, 6.92-17.96 mg/kg for Zn, 0.03-0.07 mg/kg for Ni, 0.955-1.45 mg/kg for Cr and 0.564-0.85 mg/kg for Pb. However, Arsenic was not detected in all the samples analyzed. As for the anti-nutritional factors, the concentrations in samples analyzed were found to be in the range of 111.35-123.42 mg/kg for saponins, 69.5-509.4 mg/kg for oxalates, and 0.38-0.156 mg/kg for phytate and 316.95-325.27 mg/kg for cyanogenic glycosides. The values of all these elements were found significantly below the recommended maximum tolerable guidelines level proposed by WHO/FAO except for lead (Pb), Pb was found slightly higher than the recommended limit as described. Our findings of this study reveal that most of the trace elements found in M. oleifera are below the recommended maximum tolerable limits; therefore it is safe for both human and animal consumption as well.
