Summary This paper examines the registered agricultural holdings (RAHs) in the Republic of Serbia. The present research aims to assess the current condition of RAHs in Serbia and highlight the considerable opportunities that banks and insurance companies possess to promote loans and insurance to small-scale farms. The data on Serbian RAHs were collected for the period 2018–2021. Descriptive statistics served as the primary tool for data analysis. The findings obtained indicate that the small-scale producers in Serbia face restricted access to financial services from banks, which in turn hampers their operational and investment capacities.

Summary Over the past years, the tea industry in India has started to suffer from various drawbacks, i.e. issues regarding low productivity and rising input costs (namely the uneconomic age profile of tea bushes across the tea estates of North Bengal), leading to a decline in the industry and dramatic expansion of small tea growers. Accordingly, the vast expansion of small tea plantations in North Bengal prompted this study to examine the purpose and outcome of such an expansion concept. In the present study, Bhotepatty, Maynaguri (the Jalpaiguri district), was considered due to an immense conversion of agricultural land into numerous small tea plantations in the region. The study focuses on the agricultural shift from potato fields to small tea gardens. Initially, a cumulative approach encompassing the preliminary survey work and analysis of soil physicochemical characteristics was adopted to assess the adequacy of this agricultural shift. The survey conducted revealed the lack of proper land preparation, land rehabilitation before planting, sound soil nutrient management, and soil testing programs after shifting (responsible for the depletion of major nutrients such as potassium and phosphorus in the tea soil, which can be resolved with proper and timely manuring practices). Sulphur and the organic matter, organic carbon and available nitrogen of the top soil were detected in huge amounts compared to the optimum values suggested by the Tea Board of India.

Summary The characterization of animal genetic resources includes morphometric, production and genetic characterization. This paper aims to determine the annual yield, staple length, and physico-mechanical properties of the wool of the Dupska Pramenka sheep. The average annual wool yields of a total of 130 ewes and 14 rams enrolled in the study were 2.120 kg and 3.340 kg, respectively. Wool samples were taken from the left shoulder, posterior rib, and pelvis of a total of 50 sheep (36 ewes and 14 rams). The lengths of wool staples collected from three body sites of the ewes were 20.92 cm, 21.75 cm, and 22.25 cm, respectively. The lengths of wool staples collected from three body sites of rams were 23.50 cm, 22.14 cm, and 23.64 cm, respectively. The height and length of wool fibers of the ewes were 21.97 cm and 22.85 cm on the shoulder, 22.38 cm and 23.10 cm on the posterior rib, and 23.06 cm and 23.77 cm on the pelvis. The height and length of wool fibers of the rams were 22.00 cm and 22.89 cm on the shoulder, 22.54 cm and 23.26 cm on the posterior rib, and 22.61 cm and 23.40 cm on the pelvis. The average fineness of wool fibers of the ewes was 43.08 µ, whereas the fineness of wool fibers of the rams was 45.43 µ. The Dupska Pramenka sheep were found to have mixed fibers: axillary (over 45µ), accounting for51.64% in the ewes and 54.91% in the rams, and transitional (30–45µ), accounting for 28.76% in the ewes and 32.80% in the rams. Fiber fluff (10–30µ) accounted for 19.83% and 12.98% in the fleeces of ewes and rams considered, respectively.

Summary The purpose of this study is to examine the effects of different Trichoderma spp. treatments (T1: Trichoderma harzianum, T2: Trichoderma brevicompactum, and T3: T1 + T2) on two tomato cultivars (‘Narvik’ and ‘Gružanski zlatni’) by the non-destructive monitoring of chlorophyll (Chl) and epidermal flavonol (Flav) indices and nitrogen balance index (NBI) in their leaves. The main objectives were to compare the responses of tomato cultivars considered (grown in a greenhouse) to different Trichoderma strains and a combination of Trichoderma strains. Variations in the Chl, Flav, and NBI values obtained were significantly influenced by nearly all the factors examined (namely the tomato cultivar, experimental week, and treatment), the interaction of which was found significant for all the parameters analyzed. The results obtained indicate that the combinations of strains in the T3 treatment markedly enhanced the Chl content in the ‘Narvik’ cultivar in some experimental weeks. Moreover, reduced NBI values were determined in the Trichoderma-treated ‘Narvik’ plants due to the increased flavonol content, which indicates a shift from primary to secondary metabolism. Further research, including the same cultivars and treatments, is warranted under field conditions to evaluate the physiological responses of the ‘Narvik’ and ‘Gružanski zlatni’ tomato cultivars in a multiple-stressor environment.

Summary Variation in the colour of dried tomatoes is frequently a problem for both consumers and processors. This study investigated digital imaging and applied soft-computational modelling using the Artificial Neural Network (ANN) and Adaptive Neuro-fuzzy Inference System (ANFIS) to evaluate the surface colour of microwave-dried tomato slices. The tomatoes were pretreated with water blanching, ascorbic acid, and sodium metabisulphite, then cut into slices of 4, 6, and 8 mm thickness. The slices were then dried in a microwave oven at power levels of 90, 180, and 360 W. The colour characteristics of the dried tomato slices (L*, a*, b*, colour change, browning index, hue, and chroma) were determined. The response variables were modelled and optimised using ANN and ANFIS. The efficiency and performance of the model were assessed using the coefficient of determination (R2), the root means square error (RMSE), and the mean absolute error (MAE). The results revealed the ranges of 36.70 – 48.83, 36.81 – 44.56, 31.03 – 40.34, 8.43 – 21.24, 11.78 – 39.82, 48.15 – 60.11, and 0.82 – 0.87 for the colour characteristics of L*, a*, b*, colour change, browning index, hue, and chroma, respectively. The outcomes showed that ANN and ANFIS models could make more accurate predictions. The predictive models were experimentally validated and agreed with the experimentally obtained values. However, the ANFIS model gave better performance, with higher values for R2 (1.000) and lower values for RMSE (0.02952) and MAE (0.02209). These findings will be helpful to processors and can be scaled up and adjusted for the bulk colour characteristics of microwave-dried tomatoes.

Summary This study was conducted to examine perceived effects of crop diversification on food security status of maize-based farmers in Kwara State, Nigeria. A multi-stage sampling technique was employed to obtain data from 183 maize-based farmers using an interview schedule. The data were analyzed using Herfindahl indexing, Food Consumption Score of the World Food Programme for determining household food security and Chi-square test. The results showed that the extent of crop diversification was moderate for slightly above half of the respondents (51.4%). The majority of the respondents (91.3%) had acceptable food consumption (>35), which corresponds to their food security situation. Crop diversification among the farmers indicated positive and significant influence of crop diversification on the food security status of the farmers at 1% level of significance using chi-square. More than half of the respondents perceived that crop diversification had strong effects on increased access to food preferences for an active and healthy life (56.3%), access to utilizable and digestible food (57.4%) and access to sufficient food (53.6%). The study concluded that crop diversification practices contributed to food security by increasing access to preferred sufficient, utilizable and digestible food for active and healthy life of maize-based farmers in Kwara State. Thus, extension agents should increase awareness of the importance of crop diversification for the farmers’ output in the study area.

Summary Single-parent families have become increasingly prevalent in modern times, with approximately one in five children being raised in such households in the Republic of Serbia. The reasons behind the emergence of single-parent families have changed throughout history, and society has treated these families differently. Divorces occur more frequently in modern living conditions, and extramarital births are not as rare as they were in the past. This paper presents the results of an empirical study conducted in the AP Vojvodina on a sample of 200 single-parent families. The focus is on the analysis of the financial status of single-parent families, intergenerational relationships, parenting practices, and the potential for forming new, recombined families. The conclusion is that financial hardship is a significant issue for these families, with no significant difference in their status between rural and urban areas.

Summary Salinity is one of the greatest challenges of successful agricultural production worldwide. However, seed priming might be efficient practice for enhancing seed germination and initial plant growth and development. This experiment was undertaken with the aim of assessing the impact of different priming methods on seed quality parameters and early growth of garden pea (Pisum sativum L.) cultivars under salinity stress. Pea seeds of three different cultivars were primed with water (hydropriming), KNO3 solution (0.5%), and PEG 6000 solution (-0.5 MPa) for 24h in the dark. Unprimed and primed seeds were germinated between filter papers saturated with 120 mM NaCl using the germination test. The results clearly showed that the examined parameters of primed pea seeds were substantially greater than the parameters of unprimed seeds under saline stress. Moreover, seed priming with KNO3 and PEG solutions were more effective in improving seed quality and initial growth in garden peas than hydropriming.

Summary One-year experiments conducted with one hemp variety were established to determinate the cultivation practices (growth density and pinching) which could be used to optimize the technological process of hemp varieties production for different purposes. The results showed that reduced crop density and pinching result in development of shorter plants. In denser non-pinched crops, the stem is over 180 cm high, while the plants start branching in the upper 1/4-1/5 part. In the non-pinched treatment with a larger area available for individual plants, as well as in the pinched treatments, more productive branches of less thickness develop in the lower parts. The non-pinched treatments generally produce higher stem and fiber yields, which increase when crop density is reduced. The obtained results can serve as a basis for determining certain treatments during the evaluation of production technology for different varieties of hemp intended for specific purposes.

In the non-pinched treatment with a larger area available for individual plants, as well as in the pinched treatments, more productive branches of less thickness develop in the lower parts. The non-pinched treatments generally produce higher stem and fiber yields, which increase when crop density is reduced. The obtained results can serve as a basis for determining certain treatments during the evaluation of production technology for different varieties of hemp intended for specific purposes.","PeriodicalId":221412,"journal":{"name":"Contemporary Agriculture","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125319253","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}

Summary The role of women in the growth and development of agriculture in Sri Lanka has been increasing considerably. However, inadequate attention has been devoted to the use of information and communication technology (ICT) by Sri Lankan women farmers. Therefore, the purpose of this study is to explore the application of ICT in agriculture by women farmers in the Imbulpe Divisional Secretariat (DS) Division in Sri Lanka. The primary data used in the study were collected from a total of 230 women farmers in the study area from March to July 2019, using a pre-tested, self-administered questionnaire survey. Moreover, focus group discussions and participatory observations were also conducted. The results obtained indicate that the majority of the women farmers considered were middle-aged and married, belonging to families with 4-6 members. Most of them had received education up to a junior secondary level. Their monthly total average income was 24,000 LKR. The below mentioned ICT equipment were commonly used by the women farmers for agricultural purposes: television (51.5%), the radio (43.9%) and mobile phones (52.1%). The use of personal computers, the internet and CD/DVDs was at lower levels. Although they were found to use ICT mostly for day-to-day activities, the application of ICT in their agricultural activities was fairly low. However, most of them expressed the desire to learn about ICT. According to the regression analysis conducted, a positive and statistically significant relationship was established between the farm size and respondents’ ICT literacy. Furthermore, a positive and moderately significant relationship was found between the respondents’ educational level and ICT use. High initial costs and the lack of comprehensive knowledge about ICT equipment maintenance were the major challenges they had encountered. Admittedly, as the women farmers considered apply ICT to a certain level, their use of ICT in agriculture should be further enhanced. Therefore, supplying useful ICT equipment to Sri Lankan women farmers at concession prices, accompanied by an awareness program on the use and maintenance of such equipment, would be highly beneficial.
