This study was carried out in the year November 2020. The general objective of this study was to assess the profitability and Technical efficiency of soybean producers in the municipality of Tanguiéta. A survey of a sample of 184 producers was selected at random in Center of Tanguiéta, Taïacou, Cotiakou, N’Dahonta and Tanongou of the municipality. In order to analyze the financial profitability of soybean production, the interviews focused on data in order to estimate the technical efficiency scores of each producer and to establish the operating account of the sampled producers. Thus, the most efficient and the average or weakly efficient producers whose technical efficiency scores are less than or equal to 50%. Gross margin, yield, value added per hectare and profit to production cost ratio were estimated. The results showed that the technical efficiency indices of the producers surveyed varied between 11% and 91.1% with an average of 45.62%. Soybean production is financially profitable depending on the level of technical efficiency although the yields obtained are very low for each of the groups. The profit to cost of production ratio revealed that the group of the most efficient producers has the best ratio (1.18> 0.93), showing that soybean producers are technically inefficient overall. With regard to the indicators, they are far from the production potential expected in Benin.

The study examined the factors influencing yearly consumption of turkey meat in Mymensingh city area. Data were collected from 60 consumers of turkey meat through Purposive sampling technique and face to face interview. Dummy coding was applied to code independent variables which were categorical in nature and multiple linear regression was carried out to find out the factors influencing consumption of turkey meat. Result indicated that the majority of the consumers (more than 50%) favored taste, color and aroma of turkey meat. The findings also revealed that age (P<0.05) and monthly family income (P<0.01) were significantly influencing yearly consumption of turkey meat among consumers in Mymensingh city. The major difficulty faced by the turkey farmer recognized as unavailability of turkey feed in the market, high price of day-old chick, lack of access to agricultural credit, lack of training and marketing facility and un-availability of vaccines. Analyzing the factors affecting consumption of turkey meat would facilitate in marketing decision making process of the turkey farmers and also deliver information to policy makers of Government as well as Department of Livestock Services to take necessary initiatives and support this alternative meat source to rise as a popular consumer choice.

Cassava (Manihot esculenta Crantz) is one of the staple food crops grown in Kenya. Diseases remain one of the major constraints for cassava production. Apart from other major viral diseaes Cassava mosaic and Cassava brown streak, Cassava bacterial blight (CBB) caused by Xanthomonas axonopodis pv manihotis and Xanthomonas axonopodis pv cassavae are a major constraint in cassava production in Kenya. This study was done to identify the prevalence, distribution, and farmers' knowledge of cassava bacterial blight in the coastal region of Kenya. A survey was conducted involving 250 farmers who were randomly selected from two regions of Kilifi and Taita Taveta counties. Among the 250 farmers interviewed, 61.6 % identified cassava bacterial blight symptoms in their farms. The main varieties found growing in the region were Tajirika, Karembo, Kibandameno, and Shibe which were all confirmed by farmers as susceptible to cassava bacterial blight. During the survey, plant samples were randomly collected in the field. Out of the 70 samples collected, 40 of them were confirmed positive with X.pv manihotis and X.pv cassavae which cause cassava bacterial blight. The study concluded that there is a widespread of cassava bacterial blight in Kilifi and Taita taveta counties. Kilifi County had the highest incidence of 22% with Taita Taveta having the lowest incidence of 13%. Kilifi County had a higher severity of 8% as compared to Taita Taveta which had 5% Severity. Therefore there is a need for a proper management program to be deployed in managing the disease to enhance cassava production in the region.

In order to shed light on the effect of the seaweed Ascophyllum nodosum (L.) bio stimulant on the banana fruit, foliar application (Fo), fertigation(F1) and a mix of both interventions (M) were done during 2018-2019 season on banana plants grown in South Lebanon compared with control (Ctrl). The period between flowering and harvest, the bunch weight, the weight and dimensions of fruit, were measured during the study. The results showed that the shortest period between flowering and harvest was observed on samples treated through foliar application (Fo), less with fertigation and then the mix of both (M). Those treatments were very effective in stimulating the weight of bunch and length of fruit, while a significant increase in the weight of fruit was noticed when both applications were done together (M). All treated modalities showed better performance compared with control. There was no difference in the diameter of fruit between all treatments. Therefore, the application of eco-friendly seaweed-based bio stimulant would be beneficial for the time of harvesting, and the size of banana fruits.

The purpose of this study was to determine the effect of supplemented curcumin (Curcuma longa) and red ginger (Zingiber officinale) on hematological values of broilers. Three hundred twenty one-day-old broilers were randomly distributed into 8 treatment groups with 4 replicates (pens) of 10 chicks each. The treatment diets were control groups (T01=basal diet and T02=basal diet + bacitracin), and treatment diets supplemented with curcumin (C1, C2, and C3), and supplanted with ginger (Z1, Z2 and Z3). Results showed that PVCs and hemoglobin level of the chickens fed treatment diets increased significantly (P<0.05) compare to the control diets, and the erythrocytes of the chickens fed diet supplemented with ginger increased significantly (P<0.05) compared to the control in period I (21 days of age) but no significant differences in Period II (34 days of age). Furthermore, treatment diets had no effect on erythrocyte indices of MCHC and MCV (P>0.05). However, dietary inclusion of the addition of ginger significantly decreased MCH in period I (P<0.05), but no significant differences were observed in period II. Furthermore, the treatment diets had significantly lower leucocytes and heterophils/lymphocytes ratios (P<0.05) than the control diets, but no significant differences were investigated in the percentage of differential leucocytes of eosinophils and basophils. In conclusion, the use of curcumin and ginger up to the level of 1.5% indicated the potentcy of improving the general health status of broilers. They have been able to improve the hematological values, and reduce the stress level of the chickens.

The cassava breeding program in Uganda has released many improved cultivars resistant/tolerant to cassava brown streak disease (CBSD) and cassava mosaic disease (CMD). However, many farmers have continued to use cultivars that are susceptible to these major viral diseases but with diverse attributes. There is a need to understand farmers’ cassava cultivar attribute preferences and CBSD, CMD prevalence on the preferred cultivars. A total of 150 cassava farmer fields (74 in Bukedea district and 76 in Kumi district) located in eastern Uganda were evaluated for farmers’ cultivars and attribute preferences, as well as prevalence of CBSD and CMD on the farmer selected cultivars. The eastern region was of interest in the study, due to it-being the major cassava producing area in the country. In addition, 30 cassava plants of different genotypes were chosen randomly along transects of each field and assessed for CBSD/CMD incidence and severity on preferred cultivars. Results showed that more than 64% of the farmers in eastern Uganda preferred NASE 03 due to its sweet taste and high yields, followed by NASE 14 (21%) because of its high yields. There was a significant (P≤0.001) correlation between cassava cultivars preferred and CBSD severity (r = -0.56), CBSD incidence (r = -0.53), CMD severity (r = -0.51) and CMD incidence (r = -0.39). In corroboration, the most preferred cultivar, NASE 03 was found most susceptible to CBSD and CMD in both Bukedea and Kumi districts with CBSD incidence of 62.2% and 52.7% and CMD incidence of 56.9% and 34.3% respectively. The results showed that CBSD and CMD are prevalent on farmer preferred cassava cultivars, and that farmer cultivar preference depends not only on disease resistance but also other attributes.

Agricultural spray deposition is especially important for pesticide application because low efficiency can lead to environmental pollution, poor biological efficiency and economic loss. The deposition of pesticide spray on the leave surfaces is related to the impact kinetic behavior of droplets. But after considering the deformation of the droplet, how impingement will affect the deposition is an interesting research. In this study, a superhydrophobic surface was used to replace the plant surface that the pesticide droplets may affect. An interface tracking method was proposed to characterize the impingement dynamics behaviors of different ellipsoid droplets impacting on the surface. The maximum spreading coefficient and time of ellipsoidal droplets increased with the raise of their size. A lower sized droplet has a faster spreading rate, while the center of a higher sized droplet is thinner. As the velocity of pesticide increases, maximum spreading coefficient of droplet increases with a decrease in the maximum spreading time of droplet. The simulation results can contribute to provide theoretical basis for improving spray efficiency.

The purpose of the present study was to evaluate the effect of vernalization and GA3 on seed yield and reproductive quality of summer onion. There were three vernalization treatments viz., no vernalization (control), vernalization at 5°C for 14 days and vernalization at 10°C for 14 days and four GA3 treatment viz., 0, 50, 100 and 150 ppm. The two-factor experiment was conducted in the Randomized Complete Block Design (RCBD) with three replications. Combination between vernalization and GA3 was significant on the parameters such as plant height, number of leaves plant-1, the highest number of flowering stalk, number of umbels plant-1, number of bud umbel-1, percent flowering at 45 and 60 DAP, number of seeds umbel-1, weight of seeds umbel-1, weight of seeds plant-1, weight of seeds plot-1, 1000 seed weight, seed yield, number of fruits umbel-1, percent of fruit set umbel-1and percent germination. Combined effect of vernalization & GA3 was considered the highest seed yield (280.42 kgha-1) was obtained from vernalization at 5°C for 14 days with 100 ppm GA3. The lowest values of all the parameters were recorded in the control treatment. No limitation is found in the present experiment. Combined use of proper vernalization of mother bulb and suitable concentration of gibberellic acid can be one possible way to expand onion production during the summer.

Parasitic diseases of fish are very rarely highlighted in comparison with certain parasitic diseases transmitted to humans through animals or plants such as echinococcosis, bilharziasis or fasciolosis. The aim of this study is to provide knowledge on endoparasites of the human digestive tract that also infest the digestive tracts of two species of Cichlidae fish: Oreochromis niloticus Linnaeus, 1758 and Tilapia tholloni Sauvage, 1884 caught in the Congo River (Malebo Pool). Microscopic observations were made on 42 specimens of O. niloticus fish and 42 of T. tholloni. The results obtained showed that the digestive tracts of fish Oreochromis niloticus host 8 species of parasites grouped in 6 genera, 6 families, 4 classes and 2 branches. The species belonging to the phylum Nemathelminths branch were more abundant (58.8%) than Plathelminths (41.2%). Species Trichurus trichiura (23.5%), Ascaris lumbricoides (20.6%), Strongyloides stercoralis (14.7%), Schistosoma haematobium and Schistosoma intercarlantum (11.8%) were the most frequently observed. On the other hand, microscopic analyses of the digestive tract of Tilapia tholloni revealed the presence of five species of parasites belonging to 3 branches, 4 classes, 4 families and 4 genera. Nemathelminthes (58.3%) and Plathelminthes (25%) are the most represented phylum than Amoebians (16.7%). Enterobius vermicularis (33.3%), Trichocephalus trichuris (25%), Schistosoma haematobium (20.8%) and Entemoeba hystolica (16.7%) were frequently observed. These results confirm the presence of endoparasites in congolese freshwater fish. This information is important in setting up a strategy to protect fish and consumers against these pathogens.

The aim of this study is to provide knowledge on endoparasites of the human digestive tract that also infest the digestive tracts of two species of Cichlidae fish: Oreochromis niloticus Linnaeus, 1758 and Tilapia tholloni Sauvage, 1884 caught in the Congo River (Malebo Pool). Microscopic observations were made on 42 specimens of O. niloticus fish and 42 of T. tholloni. The results obtained showed that the digestive tracts of fish Oreochromis niloticus host 8 species of parasites grouped in 6 genera, 6 families, 4 classes and 2 branches. The species belonging to the phylum Nemathelminths branch were more abundant (58.8%) than Plathelminths (41.2%). Species Trichurus trichiura (23.5%), Ascaris lumbricoides (20.6%), Strongyloides stercoralis (14.7%), Schistosoma haematobium and Schistosoma intercarlantum (11.8%) were the most frequently observed. On the other hand, microscopic analyses of the digestive tract of Tilapia tholloni revealed the presence of five species of parasites belonging to 3 branches, 4 classes, 4 families and 4 genera. Nemathelminthes (58.3%) and Plathelminthes (25%) are the most represented phylum than Amoebians (16.7%). Enterobius vermicularis (33.3%), Trichocephalus trichuris (25%), Schistosoma haematobium (20.8%) and Entemoeba hystolica (16.7%) were frequently observed. These results confirm the presence of endoparasites in congolese freshwater fish.

A field experiment was conducted to investigate the influence of different nitrogen and phosphorus fertilizer levels on dekoko (Pisum sativum var.abyssinicum A.Braun) yield and yield components as well as to establish the net benefit at each fertilizer levels. The Experiment was conducted at Mekelle university Endayesus campus in Tigray, Northern Ethiopia in 2013/14. It was laid out in a randomized complete block design with four blocks. It comprises four nitrogen (N) and phosphorus (P) fertilizer treatments combinations. Viz., Control (N0P0), 30 kg N ha-1 and 30 kg P2O5 ha-1 (N1P1), 60 kg N ha-1 and 60 kg P2O5 ha-1(N2P2) and 90 kg N ha-1 and 90 kg P2O5 ha-1 (N3P3).The highest yield (2114.55 kg ha-1), biomass (5312.5 kg ha-1), nitrogen and phosphorus use efficiency (4.58 kg kg-1) and maximum marginal rate of return (499%) were obtained when treated with N2P2. From the present results it could be concluded that 60 kg N ha-1 and 60 kg P2O5 ha-1 fertilizer rate would be optimum treatment combination for enhancing dekoko yield and yield components, NP use efficiency, and economic profitability. Therefore, application of 60 kg N ha-1 and 60 kg P2O5 ha-1 is recommended for better productivity and profitability of dekoko at low soil fertility levels.
通过田间试验，研究了不同氮、磷水平对豌豆产量和产量构成的影响，并确定了不同氮磷水平下的净效益。该实验于2013/14年在埃塞俄比亚北部提格雷的Mekelle大学Endayesus校区进行。它是在一个随机的完全区块设计中布局的，有四个区块。它包括四种氮（N）和磷（P）肥料处理组合。对照组（N0P0）、30 kg N ha-1和30 kg P2O5 ha-1（N1P1）、60 kg N ha-2和60 kg P2O5ha-1（N2P2）、90 kg N ha-3和90 kg P2O5-ha-1（N3P3）。N2P2处理的产量最高（2114.55 kg ha-1），生物量最高（5312.5 kg ha-1），氮磷利用效率最高（4.58 kg kg-1），边际收益率最高（499%）。从目前的结果可以看出，施用60kg N ha-1和60kg P2O5 ha-1的肥料是提高dekoko产量和产量组成、NP利用效率和经济效益的最佳处理组合。因此，建议在低土壤肥力水平下施用60 kg N ha-1和60 kg P2O5 ha-1，以提高dekoko的生产力和盈利能力。
