Abstract

Hog cholera is an epizootic viral diseases that attack pig. The disease is caused by Pestivirus C which belongs to the genus Pestivirus and the family Flaviviridae. Information about the prevalence and risk factors of hog cholera incidence in North Sumatra and especially in the Deli Serdang Regency became the basis for this research. This study aims to find out the prevalence and factors associated with seropositive hog cholera in Deli Serdang Regency. Samples were taken using a random sample technique with a simple random type. A total of 196 blood samples were collected from 8 sub-districts, 11 villages, and 54 farms in the Deli Serdang district. Animal and breeder data were collected with questionnaires to determine the incidence and causative factors of hog cholera seropositive. Data analysed using univariable and multivariable logistical regression tests to determine the association between hog cholera infection and risk factors. The results showed that the prevalence of Hog Cholera seroposive events at the agricultural level was 9% (5/54) and the individual rate was 10% (20/196). The results showed that the prevalence of Hog Cholera seroposive events at the agricultural level was 9% (5/54) and the individual rate was 10% (20/196). The conclusion of this research that the risk factors associated with pig cholera were landrace pigs (OR 14,28, 95% CI: 1.04-195) were more likely to have seropositif than other breeds and vaccination (OR 0.0048, 95% CI: 0.004-0.498) potential factors reducing hog cholera infection.

Abstract

Low level production efficiency of the Nigerian farmers have continued to be a major problem towards food security in Nigeria. The study examined the technical efficiency of USAID-MARKETS II project participant and non-participant rice farming households in Ebonyi State, Nigeria. A multi-stage sampling procedure was employed to select 491 rice farming households which comprise 239 participants, and 252 non- participants. Primary source of data were collected with the use of a structured interview questionnaire and field participation. Data were analyzed using mean, standard deviation, and percentage, Z statistic, and stochastic frontier Model. The result from the study, reveals that the USAID-MARKETS II project participants were 92% technical efficient while USAID-MARKETS II project non-participants were 91% technical efficient. The result further reveals that a significant difference exist between the participants’ technical efficiency and that of non-participants of USAID-MARKETS II project. Household size and education were the vital factors that improved technical efficiency of the rice farmers. Therefore, Ebonyi rice farmers should be adequately trained on modern rice production techniques by the government agency, Agricultural Development Programme (ADP) and non-governmental agencies. Also, adequate extension services should be provided to the farmers by the ADP for proper information dissemination.

Abstract

Oil palm is the most efficient crop in producing oil than other crops, such as soybean, rapeseed, and sunflower.  However, the oil palm plantation of independent smallholders faced low productivity in terms of input used.  This study aims to determine the production factors that influence independent oil palm smallholders in Kumpeh Sub-district, Muaro Jambi District. This research was conducted in three villages in Kumpeh, namely Mekarsari, Betung, and Seponjen. Samples consisted of 63 smallholders and were taken using the Simple Random Sampling method. The data were analyzed descriptively and subjected to statistical tests of multiple linear regression analysis. The results show an R2 of 0.888, indicating that the model variables can explain 88.8 percent of the oil palm production variation. The F test resulted in a value of 115.299, showing that the production variables together have a real effect on production. Partially, the independent variables that have a real and significant impact on oil palm production at a realistic level (α) of 5 percent are land area, fertilizer, and pesticides. At the same time, labor does not significantly affect palm oil production.

Abstract

Currently several species are threatened with extinction due to climatic factors, population pressure and the strong global demand for a continuous and uniform supply of fragrant, aromatic and medicinal plants. The multiplication and domestication of these species remains the only way to save them from extinction, our study is within the framework of propagation by cuttings of odorous verbena (Aloysia citrodora). In fact, some parameters influencing the success of cuttings have been studied, namely the nature of the substrate, the effect of certain rooting products and the position of the cutting in relation to the mother plant (basal or apical), the tests were carried out in a tunnel greenhouse at the ibn tofail university, faculty of sciences kenitra, Morroco. Out of 144 trials, the success rate of cuttings according to the type of substrate was 91.66%, 75% and 83.33% respectively for substrates S1 (soil only), S2 (1/2 sand and 1/2 compost) and S3 (1/3 soil; 1/3 compost and 1/3 peat). For the three products, we didn’t make combinations. but we followed the effect of each product alone, For the treatment effect, 77%, 0% and 69% respectively were obtained for Product 1 (auxin), Product 2 (based on mineral matter and amino acids) and Product 3 (seaweed extract). With regard to the position of the cutting, high percentages were obtained for cuttings from the basal position.

Abstract

Water is an indispensable element for human and other living life to live.  Therefore, in any river basin, it is very important to calculate the hydrological cycle parameters such as evaporation, infiltration, and runoff, and to determine the level of influence of natural factors affecting this process. In this study, In Goksu Basin, it is aimed to determine the effect levels of natural criteria such as lithology, soil, land use/cover, soil cover (ndvı), slope, aspect, on infiltration and runoff. In the hydrological model developed for this purpose, natural criteria, digitization formula, ArcGIS based analytical hierarchy (AHP) model program were processed and their effect levels were revealed. According to this result, infiltration and runoff values ​​are close to each other; Lithology 57.1%, soil 12.9%, land use/soil cover 18.4%, slope and aspect between 5.1% and 6.4% were determined. As a result of the model application, the total infiltration and flow amounts of 407.1 mm calculated with the converted real infiltration and runoff coefficients were correlated with the current height of 429.2 mm. It was found to be quite successful at 0.95.

Abstract

We hypothesized that phosphorus addition would result in plant morphological changes and changes in rhizosphere carboxylates among wheat and canola cultivars in different acidic soils. Concentration of carboxylates in the rhizosphere extracted with 0.2 mM CaCl2, expressed per unit root dry mass. Dry weight of root and shoot were measures after harvest; total root length, and average root diameter were determined using a scanner. Also, the concentration of phosphorus (Colwell P) in rhizosphere and bulk soil was measured using UV-VIS Spectrophotometer. Shoot and root dry mass of wheat and canola increased significantly with increasing P supply. There was significant difference in total root length and average root diameter between treatments and genotypes in both acidic soils. Citrate was the dominant carboxylate in the rhizosphere of wheat genotypes, and malate was the second one. In canola genotypes, concentration of carboxylates in the rhizosphere were at least 10 times higher than rhizosphere of wheat genotypes. Surprisingly, malonate which there was not in the rhizosphere of wheat genotypes, was the most important carboxylate in the rhizosphere of canola genotypes followed by malate and citrate. This study showed there were significant differences between plant P-efficient and non-efficient in acidic soils when we used different level of P.

Abstract

Time series data that spanned from 1981-2019 sourced from CBN, FAO, and UNCTAD data banks were used to determine the growth of fishery sector in Nigeria. The obtained data was analyzed using the two-step methodology of Engel and Granger, Granger causality, and the impulse response function. The result showed evidence of co-integration between fishery GDP growth rate and the economic phenomena. Also, the GDP growth rate of the sector is efficient as it established a long-run equilibrium but the slow pace at which it corrects the distortion in its equilibrium makes the state of the efficiency to be a weak one. Furthermore, the fishery’s GDP growth rate is affected by high inflationary trend, red-tapism, and poor credit utilization. Empirical evidences showed that unexpected local shocks on the economic phenomenon will have a transitory effect on FGDP growth rate, thus will die-out over time. It was observed that the effect of the internal mechanism on the growth rate is passive while the external system effect is active on the growth rate. Therefore, the study recommends the need for policy strengthening by the concerned stakeholders viz: tiding of inflationary trend, red-tapism, and ineffective credit utilization, thus enhancing the growth of the sector.

Abstract

Late blight, caused by Phytophthora infestans (Mont.) de Bary, is a devastating disease of potato (Solanum tuberosum L.). To identify potential sources of resistance to the disease, 32 clones received from the National Potato Research Program (NPRP) were evaluated under natural conditions at the National Maize Research Program Rampur, Chitwan in 2018 and 2019. Potato cultivars Desire, Kufri Jyoti, and Farmers local were used as moderately resistant, susceptible, and highly susceptible checks, respectively. The experiments were laid out in α-lattice design with two replications. Each experimental plot of 3.6 m2 was seeded as two 3m long rows with 0.6 and 0.25 m row and plant spacing, respectively. Agronomic practices were followed as recommended by NPRP. The disease severity was measured based on a percentage of leaf area infected using disease scale of (1 to 9) at three times in seven days intervals. Disease severity values were converted into the area under disease progress curve (AUDPC). During harvest, the total yield and its components were recorded. Potato clones differed significantly (P ≤ 0.01) for disease severity, yield, and yield components. The results revealed high genetic variability, heritability, and genetic gain for disease parameters, tuber yield, and its components. Six clones (CIP311622.9, PRP277072.122, PRP146971.135, PRP147072.27, CIP311350.27, and PRP146971.117 had lower area under disease progress curve AUDPC) values (274.25 to 421.03), showed higher resistant in both years and yielded more tuber yield (~20 t/ha) than other clones. These clones could be used to develop late blight resistant, high yielding potato varieties

Abstract

Breeds characterization can be performed based on their phenotypic traits. In poultry, the breeds characterization can be performed based on the egg characteristics. This study was carried out to characterize three Turkish laying chicken breeds (30-49 weeks of age) of White Leghorn (WL), Lohmann Brown (LB) and Ataks (AT) based on their characteristics. Total of 90 new stock eggs (30 eggs/breed) from Görukle market, Bursa city, Republic of Turkey were used for analysis. Three statistical analyses of principal component analysis (PCA), canonical discriminant analysis (CDA) and hierarchical cluster analysis (HCA) analysis were used for breeds characterization. According to egg size index, most of eggs in this study had normal size type. The highest coefficient of correlation (0.99) value was showed between egg weight (EW) and specific gravity (SG). The PCA revealed that four principal components (4PC’s) of egg characteristics capable to explain the total variance of egg characteristics in WL and LB hens about 83.10% and 78.95% respectively. Meanwhile, 3PC’s of egg characteristic in AT were explained about 81.70% of total variance in egg characteristics. The Euclidean distance revealed that LB and AT hens were grouped into similar cluster and WL hen was grouped into different cluster. In conclusion, the egg characteristics in birds study can be used to characterize of WL (73.3%), LB (93.0%) and AT (76.7%) hens.
