Specifically, the study assessed the level of participation in Fadama II cooperatives among the participants; determined the factors influencing the level of participation in Fadama II cooperatives; examined the poverty status of the participants in Fadama II cooperatives; and determined the effects of Fadama II cooperatives on the poverty status of the participants. The study was conducted in Oyo State, south-western Nigeria. A multi-stage sampling procedure was used to select respondents for this study. A total number of 150 farmers were selected for the study. Data were analyzed using descriptive statistics, participation index, multinomial logit regression model, Foster, Greer and Thorbecke (FGT) index, and Probit regression model. The result showed that the respondents participated in the designated activities carried out within their respective Fadama II cooperatives, with the maximum participation in payment of counterpart fund (100%), followed by participatory rural appraisal process (86.7%). Participation index revealed that the majority (46.7%) of the respondents had their level of participation above the grand mean. Interestingly, gender, farming experience and income from Fadama II cooperative positively and significantly influenced both partial and full participation in Fadama II cooperatives. The poverty line is observed to be ₦44300 per month ($115.36 per month). The incidence, depth and severity of poverty are estimated to be 0.28, 0.067 and 0.013, respectively. Probit estimates revealed that Fadama II cooperatives had significant and positive effect on alleviating the poverty status of the participants. Following the findings of the study, government and non-governmental organizations are encouraged to ensure that more farmers participate in Fadama II cooperatives. In addition, the approach of Fadama II cooperatives should be adopted for intervention programmes in developing countries that depend on agriculture not only for feeding their population but also as a business venture.","PeriodicalId":221412,"journal":{"name":"Contemporary Agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124613205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of such compounds is quercetin (QUE), which belongs to the flavonoid family and is found in a wide range of vegetables, fruits and plant products. The purpose of this study is to evaluate the impact of QUE on the endocrine function of rat testicular fragments under in vitro conditions. Testicular fragments from adult Wistar rats (n=9), cultured in the D-MEM medium with different concentrations of QUE (namely 1, 10 and 100 µmol/L) for 24 h at 37°C (5% CO2), were used in the experiment conducted. Following culture, the medium was separated and the levels of cholesterol (CHOL) and male hormones were measured. CHOL values were quantified spectrophotometrically, whereas the concentrations of androstenedione (ANDRO), dehydropeiandrosterone (DHEA) and testosterone (TEST) were quantified using the enzyme-linked immunosorbent assay (ELISA) commercial kit. The results obtained indicate that 10 µmol/L QUE significantly increased (P<0.001; P<0.05) the concentrations of all the steroid biomolecules considered (CHOL, ANDRO, DHEA and TEST) when compared to the control samples. Accordingly, our findings confirm the positive impact of QUE on the endocrine function and steroidogenesis of rat testicular tissue under in vitro conditions.","PeriodicalId":221412,"journal":{"name":"Contemporary Agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126813193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a vegetable crop, it is considered as one of the major cultivated crops in the world seriously affected by the climatic changes, including elevation in temperature. Therefore, in this research various morpho-physiological characteristics of chilli were studied for heat tolerance under the influence of exogenous application of proline. This research was carried out in a growth room of the Institute of Horticultural Sciences, University of Agriculture, Faisalabad, Pakistan. Four chilli genotypes were evaluated under the applied conditions. Seeds were grown in plastic pots. Heat stress (40/32 ºC day and night temperature) was applied 30 days after the emergence. Foliar spray of proline (0, 5 and 10 mM) was applied during heat stress, and after 7 days of stress the plants were harvested. The results revealed that the inhibition of chilli growth by heat stress was successfully mediated by proline application. Morphological attributes such as the number of leaves per plant, root and shoot length, plant fresh and dry weight were reduced in response to heat stress, and physiological attributes such as photosynthetic rate, water use efficiency and chlorophyll contents were also reduced in response to heat stress, except transpiration rate and stomatal conductance, which increased under heat stress and showed recovery by proline application. Exogenous application of proline promoted tolerance against heat stress in chilli genotypes and enhanced growth. All the observed traits exhibited recovery in response to proline stimulus, indicating the role of proline in mitigating the consequences of heat stress. Recovery also depends on genetic capability of various cultivars.","PeriodicalId":221412,"journal":{"name":"Contemporary Agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126063456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even though R is primarily developed as a statistical program, its application in the area of mapping and spatial statistics is becoming frequent and highly relevant. Many R packages make the mapping process easier and user-friendly, and this paper presents the most commonly used ones: “leaflet”, “ggplot2” and “ggmap”. The selection of the R package depends on the user’s proficiency in R programming but also depends on the visual quality of the map the user wants to gain. Based on the questionnaire conducted in this research, the paper recommends application of the “leaflet” package for the beginners, the “ggplot2” package for medium proficient users, and the “ggmap” package for the most advanced R users. After creating maps in R it is possible to conduct additional analysis related to processing of the spatial data contained within, and this would be a recommendation for future research. In this paper, the mapping process is demonstrated on the case study of the National Park “Fruška gora” in Serbia, and different types of maps are presented.","PeriodicalId":221412,"journal":{"name":"Contemporary Agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116083974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the past decades, the intensive selection in pig production has given priority to economically important traits resulting in greater feed utilization and obtaining more piglets from fewer sows. However, such selection practices have failed to improve the overall vitality of piglets and their ability to survive immediately after birth or during their stay in the farrowing unit. Body weight is of great importance in pig production, especially the piglet body weight at birth. A number of parameters can be predicted according to the piglet birth weight: mortality and growth rate, the physiological status of the heard, sensitivity to external influences, vitality and etc. The purpose of this paper is to determine the piglet body weight variation from birth to weaning (measured at birth, 3 hours after birth, 24 hours after birth and at weaning) and to examine the relationship between the birth weight of piglets and their body weight during the transition into nursing. A total of 105 piglets were enrolled in this study from the F1 generation sows followed through eight consecutive parities. The paper presents the results obtained using descriptive statistics, as well as variance and correlation analysis. The relationship between the piglet body weight at different stages of their life and overall production parameters was found to emphasize the centrality of housing conditions as the piglet weight at birth exerts a great impact on the body weight of older piglets, especially in the first days of the piglet life. Therefore, the proper care of piglets in farrowing units is of paramount importance to pig production, especially because piglets have lower body weight at birth nowadays than before.","PeriodicalId":221412,"journal":{"name":"Contemporary Agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123028078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The vitality of rural communities, which represent a specific socio-spatial phenomenon, affects the development of global society and is inextricably linked to the development and issues of urban areas of each society. Both in theory and development practice, rural development as a complex and enduring process has long been unjustifiably reduced to the economic-agrarian matrix, often reflected in the modernization of agriculture and the centralized and sectoral management of and influence on rural development. The primary focus of this paper is on the social capital of rural communities, i.e. social relations and connections within local rural communities which, alongside other important development factors, are one of the prerequisites to maintaining their vitality. The paper presents the results of a survey on social capital conducted on 281 farms in the region of Vojvodina (Serbia), indicating the characteristics of the social capital on the farms considered and the farmers’ attitudes towards the development and life of their local communities. The social capital of the surveyed farmers was found to be only relatively good, suggesting that the overall social capital in Serbia is underdeveloped because all the farms considered are located in Vojvodina, i.e. the most developed agricultural area in Serbia characterized by rural settlements with the most favorable infrastructural, demographic and economic conditions.","PeriodicalId":221412,"journal":{"name":"Contemporary Agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129699364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is limited information regarding farmers’ awareness of GAP and its applications under the circumstances of farming in the country. Therefore, assessing farmers’ attitude is a timely requirement for directing farmers towards good agricultural practices. Thus, the objectives of the research were to assess the level of awareness of GAP program, relationship between socio-economic factors and awareness of GAP, farmers’ attitudes towards GAP program, factors affecting the willingness to adopt GAP program and the potentials and constraints in implementing GAP program in Galle District. A sample of 100 vegetable farmers in the district was selected through a multi-stage simple random sampling technique. Data were collected from March to July 2018, through a self-administered questionnaire survey and analyzed using descriptive statistics and chi-square test. The results revealed that the majority of vegetable farmers in the district were middle-aged males who had studied up to GCE ordinary level and they received a monthly income of 24000 LKR. Their age, gender, educational level and experience were significantly associated with the level of awareness of GAP program. However, despite their positive attitude towards GAP, most farmers were unwilling to take a risk to adopt GAP due to many issues such as lack of required inputs, capital, required field conditions, information and technical know-how. There are several potentials and also many constraints for implementing GAP in the district. Therefore, providing firstly better theoretical knowledge and then providing the main requirements will motivate more farmers to adopt GAP in their vegetable production procedures. Research studies related to application of GAP by Sri Lankan farmers are still at a lower level. This research thus will be useful for different stakeholders related to adoption of GAP in Sri Lanka.","PeriodicalId":221412,"journal":{"name":"Contemporary Agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114990334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study specifically examined the perceived causes of economic recession, investigated the perceived effects and identified the coping strategies adopted by the male and female members of the rural households during economic recession and their level of adoption. A multistage procedure was used to select 120 respondents from 6 local Government Areas of the State. An interview schedule was used to collect data from the respondents. The collected data were analysed using appropriate descriptive and inferential statistics such as frequency counts, percentages, means and independent T-test analysis. The mean ages of the male and female respondents were 45.2 ± 14.1 years and 37 ± 12.6 years respectively. The majority of the males (78.3%) and females (80%) were married with the mean household size of 7 ± 3 people for the male and 6 ± 2 for the female respondents. The cause of economic recession mostly perceived by the male and female respondents was poor economic planning (mean=3.87, 3.77), while prioritizing spending (mean=2.80, 2.52) was the most adopted strategy by both males and females. No significant difference was found in the effects of economic recession on the male and female respondents (t = -0.19; p >0.05) and likewise no significant difference was found in their economic recession coping strategies (t=0.115; p ≥ 0.05).
