The widening supply-demand gap of poultry products in Nigeria calls for urgent attention toward improving the production and productivity of poultry with a special interest in underutilized poultry species. This study was carried out to examine the level of production of underutilized poultry species and the factors influencing it in the Iwo ADP Zone of Osun State. A multistage sampling procedure was adopted to select 150 poultry farmers for the study. Data were obtained through physical interview of the farmers, then analysed using descriptive statistics and ordinary least square (OLS) regression. Results showed higher percentage of males in poultry production and mean age of the poultry farmers was 49.19±12.40 years with a mean length of experience in poultry keeping of 11.0±7.4 years and mean flock size of 68± 17. It was deduced from the study that majority (77.3%) of the poultry farmers had no or limited access to extension services. As determinants of the rearing of underutilized poultry species in the study area, results of multiple linear regressions showed the coefficients of the age of poultry farmers, and length of poultry farming experience was positive and statistically significant (P< 0.01). Household size was also positive and statistically significant (P< 0.05). Based on the findings, the study, therefore recommends the need for an enlightenment campaign and awareness on the importance of rearing underutilized poultry species and strengthening the livestock extension services for effective and result-oriented service delivery to the poultry farmers.

The results of soil losses management studying due to wind and water soil erosion crops rotations proposed based on methodologies of NSC “Institute for Soil Science and Agrochemistry Research named after O.N. Sokolovsky". The main purpose of our research was to assess the soil losses under influence of wind and water erosion in crop rotation. The works were planned to determine how erosion types correspond to crops or having the same effect on a similar field parts in the crop rotation of Ukrainian Eastern Steppe part. It was also planned to compare soils losses in similar gradations (allowable, slight, moderate, high) with the following analysis of the differences in the manifestation dynamics under different agricultural crops (fallow, winter crops, barley, oat, corn for grain, corn for silage, millet, peas), and different parts of fields. It is proposed when determining the erosion risk of the territory, the areas of such soils must be protected by such crops with minimal losses from the destructive effects of wind erosion and surface runoff. It is possible to state the cumulative manifestation of erosion and deflation on the territory of the region, but it is impossible to separate the contours of eroded and deflated soils in detail, therefore, in erosion situations proposed to obtain separate influence of each erosion (wind and water) on already eroded or erosionally hazardous lands.

The results of research on determining the effectiveness of using microfertilizers and fungicides on hybrid sugar beet crops are given. Research was conducted in 2021-2022 at the experimental field of Bila Tserkva National Agrarian University. In the experiment, sugar beet hybrids were studied: Libero and Margarita KWS; Microfertilizers: control without their use, Florenta beet (1.5 l/ha), Intermag beet (2 l/ha); Fungicides: control (without their application), Alto super 330 EC (0.5 l/ha), Amistar Extra 280 SC (0.6 l/ha), Styer 500 (0.5 l/ha). It was established that the highest yield of root crops and the coefficient of energy efficiency (Сее) in the sugar beet hybrids Libero and Margarita KWS was obtained on the variant with the use of the microfertilizer Intermag beet (2 l/ha) and the fungicide Amistar Extra (0.6 l/ha) – 52.1 і 58.3 т/га та 3.2 і 3.6, respectively. The use of fungicides allows you to increase the sugar content by an average of 0.8–1.2%, microfertilizer Florenta beet (1.5 l/ha) by 0.6%, and microfertilizer Intermag beet (2 l/ha) by 0.8%, compared with control variants. The best indicators of the technological qualities of sugar beet root crops were on the variants of combined application of microfertilizers and fungicides, while the conductometric ash content was the lowest, and calculated sugar content and dry matter content were the highest.

The vulnerable group is susceptible to various economic and social challenges. Understanding their livelihood is a prerequisite to addressing these menaces. Therefore, this study assessed the livelihoods of the vulnerable group and the factors responsible for their diversification in rural southwest Nigeria. Data collected were analysed using descriptive statistics, principal component analysis, the Simpson index, and the Tobit regression model. Results revealed that food crop production, cash crop production, livestock and fishing, forest and forest products, artisanship, remittances, wages and salaries from non-agriculture, and trading were the different means of livelihood among the rural vulnerable group. All the vulnerable groups derived income from farming. Cash crops, food crops, and livestock and fishing contributed 26.1%, 22.7% and 17.9% to household income, respectively. Thus, agriculture contributed the most (66.7%) to their total household income.This is followed by wages and salaries from non-agriculture (12.1%), trading (9.3%), artisanship (8.1%), remittance (2.2%) and forest and forest products (2.0%). The vulnerable group had a low level of livelihood diversification. Educational level, farming experience, total income, access to credit, age, and distance to the market were responsible for their level of livelihood diversification. This calls for government and non-governmental intervention to support the vulnerable group by providing financial assistance (credit or grants), farming inputs, and education to improve their livelihood and enhance their livelihood diversification.

In the context of globalization, rural tourism offers diversity in close connection with regional specificity. In this sense, there is an increase in the tourist offer oriented towards the traditional, towards the authentic. The entrepreneurial attempts to reflect the local authentic in the field of tourism are not well defined, often the specific traditional elements are not respected, creating an inappropriate mixture of architectural, gastronomic and cultural styles. Thus, the need to define the concept of authenticity in rural tourism based on vernacular culture is noted and this is the main aim of this paper. Also, theoretical items such as rural space, rural tourism, vernacular, and authenticity are defined and systematized, and essential parameters like elements, principles and methods for substantiating authentic rural tourism are synthesized. These ideas are critically analyzed, and discussed, based on representative documentation from Romanian and foreign literature to which the authors added their modest contribution. Authentic rural tourism offers interesting experiences precisely through originality, local specificity, diversity, in a cultural and geographical framework that completes the knowledge and offers the tourist a truly authentic experience. In this way, an increase in tourist interest is achieved and the foundations are laid for sustainable, representative economic activities at the rural level.

The study analyzed the possibility of capitalizing compost resulting from fermentable organic waste, for the purpose of growing plants. To prepare the growth substrates, compost (Comp) was used in a single variant (V2), as well as in a mixture with peat (Pea) and vermiculite (Ver). Depending on the weight in the mixture (% in volume), the experimental variants resulted: variant V3 – Comp:Pea:Ver, 20:70:10; variant V4 – Comp:Pea:Ver, 30:60:10; variant V5 – Comp:Pea:Ver, 40:50:10. For comparison, a control variant (V1) based on garden soil (GS) was used. The biological material was represented by the species Tagetes patula Durango® Tangerine. The experiment was done on pots. Vegetative parameters, tagetes shoots diameter (TsD), tagetes shoots number (TsN), tagetes plant height (TpH), tagetes plants diameter (TpD) were determined and the ratio TpH/TpD was calculated; floral quality indices, tagetes inflorescence number (TiN), tagetes inflorescence diameter (TiD). The determinations were made during the vegetation period, at six different times, T1 to T6, between March and October. Correlations were identified between the considered parameters and indices. Based on the PCA, the common orientation of the vegetative parameter TpD with the index of floral quality TiD, respectively of the parameter TpH with TiN was found. PC1 explained 45.648% of variance, and PC2 explained 22.774% of variance. Scaling dendrogram resulted for variant classification. Mathematical models resulted through regression analysis, which described the variation of floral quality indices (TiN and TiD) in relation to vegetative parameters, with 3D graphic representation and in the form of isoquants.

The purpose of the paper was to analyze cereal production in Dolj County and in Romania in the period 2017-2021 in order to identify the main trends, based on the statistical data provided by National Institute of Statistics and processing them by comparison method and time and structural indices. Dolj County has a total area of 741,401 ha (7th place at national level – 3.11% of the total), an agricultural area of 585,135 ha (2nd place at national level – 32.57%) and an arable area of 488,560 ha (2nd place at national level – 39.03%). The county is characterized by favorable agro-productive conditions for cereal cultivation, taking into account climatic factors and soils specific to the county (for example, sandy soils for rye cultivation). The county cultivated (on average) 331,450.80 ha with cereals, predominantly wheat and grain maize (60.5, and 26.53% of the total), obtained a total production of 1,567,667 t (predominantly wheat and maize with 54.89 and 33.96% of the total), and the average yield per hectare reached 4,728 kg. It can be said that Dolj County can decisively influence, in certain situations, the cereals market in Romania and the South-West Oltenia Region, but it must be aimed at improving the performance of this side of vegetal activity, in order to capitalize on the existing potential.

This researchwas carried out in a stationary field trial on a typical deep low-humus black soil at the experimental field of Bila Tserkva National Agrarian University. The aim of the research was to assess the productivity of a crop rotation using the main tillage of the soil, which included mouldboard for sunflower (25-27 cm), mouldboardless for corn (25-27 cm) and for soybeans (16-18 cm) and disking for winter wheat, spring barley and white mustard (10-12 cm). The results proved that in this crop rotation the productivity was the highest. Cenotic resistance to weeds was highest in winter wheat and lowest in corn. During the period of the experiment (2012-2021) the potential weediness on unfertilized plots was unchanged and the annual application of 12 tons of manure + N95P82K72 and 16 tons of manure + N112P100K86 per hectare of crop rotation increased this indicator by 2.4 and 6.0%, respectively. The used for the main cultivation of the soil mouldboardless and disking (continuous shallow) causes the spread of rhizomatous and root rhizomes and the localization weeds and an increase the number of seeds of other species in the upper soil layer (0-10 cm). In the weed component of agrophytocenoses of crop rotation the increases of dicot species under mouldboard tillage and monocots - under mouldboardless tillage. Productivity of crop rotation on fertilized and unfertilized plots is almost at the same level for mouldboard and mouldboard & mouldboardless tillage but it is significantly lower for mouldboardless and disking tillage. The highest efficiency in crop rotation provided by differentiated cultivation with used of 12 tons of manure + N95P82K72.

The study comparatively analyzed 15 maize genotypes, under the aspect of production potential and some quality indices. The experiment was organized within the ARSD Lovrin. Eight maize genotypes from Lovrin (L experimental code; L1 to L8) and seven genotypes represented by commercial hybrids (CH experimental code; CH9 to CH15) were considered. The production of maize ears, Y(ears), varied between 6,236.00±570.14 kg ha-1 in hybrid L4 and 12,839.33±570.14 kg ha-1 in hybrid CH15. The physical grains production, Y(pgp) varied between 5,371.00±524.39 kg ha-1 in hybrid L4 and 11,640.00±524.39 kg ha-1 in hybrid CH15. The recalculated production (STAS, 14% moisture), Y(STAS) varied between 5,371.00±507.36 kg ha-1 for hybrid L4 and 11,579.33±507.36 kg ha-1 for hybrid CH15. The protein content (Pro, %) varied between 7.20±0.33% in the CH14 hybrid and 10.60±0.33% in the L3 hybrid. The oil content (Oil, %) varied between 5.20±0.09% in the CH15 hybrid and 6.40±0.09% in the L1 and L2 hybrids. According to PCA (95% confidence), the hybrids from group L were placed associated with the content of protein (Pro) and oil (Oil) as biplot. Hybrids from the CH group were placed associated with the Y(STAS) parameter. PC1 explained 72.693% of variance and PC2 explained 17.704% of variance. For the selection process of genotypes in breeding programs, the genotypes from the CH group (commercial hybrids) are of interest for the production potential, and the genotypes from the L group (Lovrin) are of interest for the quality indices (Pro, Oil).
