Assessment of nutritional contents of different parts of moringa plant from selected districts of Oromia, Ethiopia
Full text linkMoringa plants are among high-value trees and belong to the Moringaceae family, consisting of 13 species and highly distributed in Africa and southern Asia. It is multi-purpose tree with medicinal, nutritional, industrial and socio-economic values. Preliminary information indicates that the human dietary usage of the edible parts of these species is limited. Assessment of the nutritional quality of different moringa parts was not well documented in Oromia. Hence, the aim of this activity is to assess the nutritional qualities of different parts of moringa collected from different districts of Oromia. Sample collection was done from Bako from West Showa, Bishoftu from East Showa, Dalo Mena and Goro from Bale Zone, of Oromia representing mid and low land agro-ecologies of the region. Three to four sampling PAs were used from each district. Different parts of Moringa, namely, leaf, pod, bark, seed and flower were collected from the four districts at least in triplicate. The collected samples were made to dry at room temperature, milled with coffee miller, and passed through a 1 mm standard sieve. The prepared samples were analyzed for proximate and mineral compositions using standard methodologies. The result obtained indicated that leaf is rich in nutrients Ca, Na, Mn and Zn. Moringa flower is rich in nutrients like Zn and Mn, and second in K composition next to pod. The pod is also rich in K and Zn, while the fat and CP contents are high in the seed part of moringa. Generally, Higher % CP, K and P were found from the Bishoftu collection, while Mg, Ca and K were higher for the collection from DM. Bark is poor in protein content compared to other parts of the plant. However, Ca, Mg and Zn are double the optimum composition of plant material. Finally, it is possible to use different moringa parts for food fortification, where determination for antioxidant and nutritional composition analysis is mandatory, as well as future research directions.

Evaluation of various blended fertilizer types and rates for better maize (Zea mays) crop production in Yeki woreda, Sheka Zone, South West Ethiopia
Full text linkAppropriate fertilization methods for a particular crop based on real limiting nutrients and crop demands are cost-effective and wise utilization of fertilizers for long-term agricultural productivity. An experiment was done to assess alternative fertilizer types and rates for better maize production during main cropping season of 2018 and 2019. The fertilizers were set depending on the study area\u27s limiting nutrients, which include NPS and NPSB at various rates. There are seven treatments in the experiment: (1)no fertilizer; (2) NPS: 69N, 54P2O5, 10S; (3) NPS: 92N, 72P2O5, 13S; (4) NPS: 115N, 90P2O5, 17S; (5) 69N, 54P2O5, 10S, 1.05B NPSB; (6) 92N, 72P2O5, 13S, 1.4B NPSB and (7) 115N, 90P2O5, 17S, 1.7B NPSB. Treatments were placed out in a randomized complete block design and replicated three times on two farmers\u27 fields. The study showed that using NPS mixed fertilizer had a substantial impact on maize output when compared to the control. Treatment 2 (NPS; 69N, 54p2o5, 10S) yielded significantly greater maize yield over control at (P<0.05). Similarly, with an appropriate marginal rate of return (128.2%), treatment 2 (NPS; 69N, 54P2O5, 10S) had the largest net benefit (30908.5 ETB/ha). As a result, maize producers in the area of study should use NPS with the nutrient ratios of 69N, 54P2O5 and 10S.

Relationships between body weight, body condition score at breeding and reproductive and progeny performance in Kiko meat goats over two breeding cycles
Full text linkBody condition scores (BCS) and/or body weights (BWT) are often used as visual or tactile management tools to evaluate and improve reproductive competency in pasture-managed small ruminant animals. This study was designed to evaluate relationships between BCS, BWT and reproductive traits (number born alive and weaned, litter size, birth and weaning weights) in 16 purebred Kiko, 11 purebred Boer and 7 Kiko x Boer crossbred meat goat dams that were semi-intensively managed and bred to both Boer and Kiko bucks. BWT was recorded using a scale and palpable BCS scale of 1 to 5 (1= emaciated to 5= obese) and was subjectively determined at breeding, parturition and weaning. Pearson correlation coefficient (r) analysis was used to determine the relationships between residual values of reproductive and progeny performance and BWT or BCS. Pre-partum BCS and weaning BCS had a correlation of r=0.09. A moderate correlation was observed between BWT at breeding and the number born alive (r=0.36) suggesting that pre-partum BWT is the key body conformation measurement linked to the reproductive performance of dams both at birth and weaning. Both at breeding and at weaning BCS were negatively correlated with litter size (r= -0.11) and birth weight (r=-0.32) and weakly correlated with the number born alive (r=0.06). Also, negative correlations were obtained between BCS at weaning and kid weaning weight (r=-0.58) and number weaned (r=-0.26). Although BCS had no significant (P≥0.05) effect on kg kids born per dam, birth weight of kids, and kids weaning weights, it is evident that a BCS score of 3 at the mating time could optimize reproductive performance. The results of this project established the important roles that pre-breeding BWT and/or BCS have on reproductive performance (kidding rate) in meat goat herds. We recommend their evaluation as a useful management tool for distinguishing differences in the pre-partum nutritional needs of meat goat herds, especially in the pasture-based production system.

Evaluation of efficacy of fungicides against ginger leaf spot (Phyllosticta zingiberi) disease epidemics at Tepi Southwestern Ethiopia
Full text linkThe most devastating disease that affects ginger production and productivity in Southwestern Ethiopia and lowers qualitative and quantitative rhizome yields is ginger leaf spot, which is caused by the pathogen Phyllosticta zingiberi. In Tepi, Southwestern Ethiopia, during the main cropping seasons of 2020 and 2021, a field experiment was carried out to assess the efficacy of several fungicides in managing epidemics of ginger leaf spot disease. The fungicides evaluated were Ridomil Gold MZ 68 WG (Metalaxyl-M), Ethiozeb 80% WP (Mancozeb), Shega 50 WP (Copper oxychloride), and Matico (Metalaxyl 8% + Mancozeb 64% WP). While the plot without spray is used as control. The results of the experiment indicated that among the different fungicides tested four times spray of Matico (Metalaxyl 8% + Mancozeb 64% WP) starting from the appearance of the disease on the field within 15 days intervals produced the lowest leaf spot disease severity of 10.2% followed by foliar spray with Mancozeb (Ethiozeb 80% WP) 16.2% first at disease appearance and then 3 times at 15 days intervals. Similarly, the highest yield of 16.3 t ha-1 was also obtained by foliar from the plot foliar spray of Matico (Metalaxyl 8% + Mancozeb 64% WP) which is followed by spraying with Mancozeb (Ethiozeb 80% WP) with a yield of 12.56 t ha-1. Therefore four times foliar spray of Matico @ 2.5 kg ha-1 is highly effective against leaf spot disease of ginger in southwestern Ethiopia.

Techno-economic analysis of a biomass-powered inclined bed dryer for maize drying
Full text linkThe study assessed the technical performance and economic viability of a 200 kg capacity biomass-powered inclined bed dryer for drying maize. The dryer recorded an average air temperature of 73.54˚C in the plenum, which reduced the moisture content from 23.25% (w.b) to 13.61% (w.b) at a drying time of 2 hours 40 minutes. This resulted in a drying rate, drying efficiency, and specific energy consumption of 9.50 kg/h, 71.37%, and 25.70 MJ/kg, respectively. The germination potential of dried maize grains was 80% compared to 93% for grains assessed before drying. Stress-crack analysis revealed a lower percentage of no-cracks for dried maize (71%) than maize gains before drying (98%). There was a statistically significant difference between the dried and the undried maize grains for germination viability (p = 0.01) and stress crack analysis (p = 0.00) at α=0.05. At a drying charge of US 1313.48 and internal rate of return of 44%. Evidently, adopting the dryer could contribute to reducing post-harvest loss of maize at the smallholder level and increase farmer\u27s income.

Lipid oxidation in emulsions and bulk oils: a review of the importance of micelles
No full textInternational audienceLipid oxidation is a major cause of quality deterioration in food products. In these foods, lipids are often present in a bulk or in emulsified forms. In both systems, the rate, extent and pathway of oxidation are highly dependent on the presence of colloidal structures and interfaces because these are the locations where oxidation normally occurs. In bulk oils, reverse micelles (association colloids) are present and are believed to play a crucial role on lipid oxidation. Conversely, in emulsions, surfactant micelles are present that also play a major role in lipid oxidation pathways. After a brief description of lipid oxidation and antioxidants mechanisms, this review discusses the current understanding of the influence of micellar structures on lipid oxidation. In particular, is discussed the major impact of the presence of micelles in emulsions, or reverse micelles (association colloids) in bulk oil on the oxidative stability of both systems. Indeed, both micelles in emulsions and associate colloids in bulk oils are discussed in this review as nanoscale structures that can serve as reservoirs of antioxidants and pro-oxidants and are involved in their transport within the concerned system. Their role as nanoreactors where lipid oxidation reactions occur is also commented
Impact of tobacco cultivation on soil and human health in the agricultural ecosystem at Tangail region of Bangladesh
Full text linkThe study was conducted to determine the impact of tobacco cultivation on soil and human health in the agricultural ecosystem at Bhuapur and Kalihati upazila of Tangail region from January to December 2019. Among them, 40 soil samples were collected, each 20 from Kalihati and Bhuapur Upazila. Among 20 samples, every 10 samples were collected from tobacco and non-tobacco land at a depth of 0 to 15 cm in Bhuapur, 0 to 15 and 15 to 30 cm in Kalihati Upazila. The soil pH, organic matter (OM), total nitrogen (N), available phosphorus (P), available sulfur (S), available zinc (Zn), exchangeable potassium (K), exchangeable magnesium (Mg) and exchangeable calcium (Ca) were analyzed in the laboratory of Soil Resource Development Institute (SRDI), Tangail. In Kalihati Upazila, tobacco land showed significantly higher content of OM, available N, available P, available Zn, exchangeable K and exchangeable Mg, whereas pH was low in non-tobacco land. Surface soil (0 to 15 cm) and tobacco land showed significantly higher content of S than sub-surface (15 to 30 cm) soil and non-tobacco land. On the other hand, there was no significant variation between tobacco and non-tobacco land on soil properties in Bhuapur Upazila. In both Upazilas, all the nutrients except exchangeable Ca and Mg were lower than optimum in tobacco and non-tobacco land, which was unsuitable for crop cultivation. The cost of production was higher in tobacco land than in non-tobacco land in both Upazilas. About 36% of farmers informed that they were suffering from various diseases due to tobacco cultivation and curing. Tobacco cultivation in these areas degrades soil health and the agricultural ecosystem and releases nicotine into the environment, hampering food safety and human health. The study indicated that tobacco cultivation should be replaced by other crops to protect soil quality and human health.
