The present paper aimed to evaluate an agricultural holding, based on technical and economic analyzes for the period 2015-2019, whose resources and activities related to the last year were optimized. The optimization led to the improvement of the overall economic performance by the rational allocation of resources and the establishment of the crop structure in order to obtain large yields. The optimization process was accomplished by using a mathematical model of linear programming consisting of variables, constants, constraints and objective function. The modelling and simulation of the real system, by using the simplex algorithm, led to the identification of suitable solutions and implicitly obtaining a maximum effect with a minimum effort (high incomes with minimal expenses).

In the current context of increasing concerns for healthy agri-food systems, the adoption of ecological farming practices has gained ground and visibility both as sustainable approach to the farming activity and as scientific approach. The paper intends to analyse the differences between the organic and conventional systems of livestock raising in Dornelor Basin, Suceava county. The comparison of the two systems was based on several dimensions – labour, agricultural incomes, use of agricultural inputs, adoption of ecological farming practices, etc. The results obtained showed that both farming systems support, in different proportions, the health of ecosystems and inhabitants in the investigated area.

Rural areas in Nigeria are the centres of agriculture-based economic activity and fuel the livelihoods of 70% and contribute over 22.30% of the country’s Gross Domestic Product (GDP). It is estimated that Nigerian agricultural output would increase if farmers were able to access the finance they need to expand both the quality and quantity of their produce. The limited level of Agricultural credit is considered an important factor for increased agricultural production and food security because, it enhances productivity and promotes standard of living by breaking the vicious cycle of poverty of small scale farmers. The study was conducted on Overcoming Small holder Farmers’ Financial Exclusion using Anchor Borrowers’ Programme in Yola North and Yola South Local Government Areas, Adamawa State, Nigeria. Data were collected using structured on 94 farmers randomly selected. Descriptive and inferential statistics were used in the analysis of the data collected. Descriptive analysis revealed that respondents were relatively young with a mean age of 40 years, a mean family size of 6 people who are mostly small holder farmers with the mean farm size of 3.21 hectares and are experienced with a mean experience of 10 years. Logit result with Diagnostic statistics and VIF test results indicated that the Hosmer and Lemeshow goodness of fit test indicating that our model fits the data well. The model also correctly predicted 73.68 % of the dependent variables. The estimated VIF suggested that the explanatory variables specified in the model do not cluster together or exhibit multicollinearity tendencies. This implies that the estimates of the model to an appreciable extent are consistent and unbiased, stable over time and there was also no problem of multicollinearity. Furthermore, the result showed that membership of cooperative society, age, primary occupation, income and training were statistically significant and increases the probability of access to agricultural credit. Government policies that would encourage young people to go into agriculture should be sustained by the government at all levels in areas of credit supply, training and supply of basic production inputs to boost production, increase food security and reduction in poverty. Farmers should be encouraged to form cooperative societies to maximize the economics of scale.

Tropical forest contains many plant species that are cultivated for food but they are neglected and underutilized despite their importance. This study examined phenotypic variation of trees and fruits of Blighia sapida conducted at (Akure, Owo and Akoko) within Ondo State, Nigeria. Five healthy trees were selected and twenty (20) matured fruits were collected from each tree. Data collected from selected trees were tree growth, fruits and seeds. The result indicates that highest tree height 14.0 m was recorded in Akoko and 8. 00 m was found in Akure B. sapida trees but tree dbh shows that 19. 46 cm, 19.44 cm and 18.34 cm were found for Owo, Akoko and Akure trees while 8. 48 m, 7. 60 m and 7. 12 m were for crown diameter found for Akure, Owo and Akoko tree respectively. But for seed parameter it shows that 1.85, 1. 75 and 1.71 were found for the seed no/fruit for Akoko, Owo and Akure, and 2.14, 2. 03 and 1.99 cm for seed length for Akoko, Akure and Owo respectively. Seed breadth ranged from 1. 67 cm – 1.81 cm and seed weight ranged from 8. 19g -7.61g. Fruit parameters show that highest fruit length was found in Akoko with 4. 90 cm while Owo fruits had least with 3.78 cm, for fruit breadth Akoko had the highest value of 4.08 cm Owo had the last value of 3. 37 cm but for fruit weight Akoko had the highest with 42. 33 g while Akure had the least weight of 42.20 g respectively. The variation in fruit and seed of B. sapida could be due to climatic, edaphic factors and cultural factors.

Agricultural sector contributes to water, soil and air degradation, as well as biodiversity loss. Agri-environmental measures are a predominantly voluntary policy instrument that seeks to encourage farmers to implement environmentally friendly practices on their farms. This paper aims at providing an overview of policy drivers, goals and effects discussed in literature, as well as factors affecting farmers’ decision to participate in AEM. Most studies geographically belong to Western Europe (United Kingdom, Germany, Sweden, Belgium, Denmark) and there is a disproportionately smaller amount of similar analyzes for Central and Eastern Europe. Connecting AEM’s policy impact to understanding farmers’ participation motives contributes to comprehending just how complex the concept of policy implementation is now and will be in the future. The effects of AEM mostly depend on the specific measure implemented, phenomenon investigated, and region observed. Farmer’s interest to get involved in AEM depends on the potential economic benefit, socio-demographic factors, social connections, personal beliefs and trust in public institutions. Therefore, the policy should adapt to stakeholders’ heterogeneity and send straightforward messages to farmers showing clear interrelation between the policy, farmers’ uptake and the desired environmental outcome.

The paper aimed to analyze the status of pork market during the period 2017-2019 under the impact of African Swine Fever (ASF) in order to assess the consequences on pig livestock, pork production, trade, and price compared to the period 2014-2016. Using the data provided by Faostat and National Institute of Statistics, and the usual methods specific to such an analysis: fixed index, trend line, regression equations and determination coefficient, the obtained results have pointed out that in the interval 2017-2019 versus 2014-2016, of pig livestock, ASF has amplified the decline of pig livestock, slaughtered pigs and their live weight, and pork production. The higher demand than offer on the domestic market increased imports to assure food security and increased pork price. Farmers are discouraged to grow pigs due to the lack of biological material, high price for piglets and feedstuff, high production cost and the high risk that their business to fail, as long as subsidies and aids are missing in pig farming. In consequence, it is needed a new strategy which has to be adapted to the actual situation at the European level destined to counteract the spread of ASF by using efficient measures of traceability and biosecurity along the pork chain. Veterinary authorities have to join their forces to eradicate this disease and produce a vaccine for saving pig livestock. Subsidies and aids are required to sustain pig growing in Romania, where pork is a strategic food.

This work investigated producing vinegar from unmarketable 'Taleese', 'Athwi' and 'Hellawi' Libyan date cultivars. Sugar was extracted from 'Athwi' and 'Talees' dates by soaking in distilled water at 1:3 (w/w) for 10 hours and pressing while 'Hellawi’ dates were mixed with distilled water at the similar ratio, heated at 80°C and agitated for 2 hours and pressed. Total soluble solids (TSS) of solutions obtained from the three cultivars were 16.5, 17.4 and 25.0 °Brix, respectively. Solutions were adjusted to 15.5°Brix and 8 litre of solution of each cultivar were fermented in 15L setup equipped with an airlock. Baker’s yeast was added and solutions were incubated at room temperature averaging 22°C. The process lasted 9 days, afterward aerobic acetification was carried out by adding virgin date vinegar at 10% (v/v) and solutions were kept under same conditions. Weekly measurements of titratable acidity (TA) and alcohol percentage were made until alcohol content dropped below 1%. The process lasted 60 days for 'Taleese' and 'Athwi', while 'Hellawi' took additional 11 days. Both fermentations were described by linear relations (R2 >0.97). In the anaerobic reaction, cultivars were significantly different in their alcohol percentages and TSS but were similar in acidity and pH. In the aerobic fermentation, no significant differences in TA, pH but significant different in alcohol residues and TSS were recorded. Moreover, sensory evaluation of the three kinds of vinegar was made on acidity, taste, and acceptance; again no significant differences were recorded. Color analysis in Hue angle, Chroma and L* were also made, vinegar of the three cultivars were significantly different; 'Hellawi' vinegar was much darker than 'Athwi' and 'Talees'. Quantification of acetic acid showed its contents above 5% (v/v), representing nearly 85% of total acids. The study demonstrated the potential of producing good quality vinegar from unmarketable Libyan dates.

Regional disparities can be perceived as a cross-cutting category of many disciplines, but most often they can be perceived as economic differences of regions' level of maturity. Regional disparities in business are addressed mainly by Asian countries. In European countries, research on regional disparities in agriculture is paying less attention. The article focuses its attention on the research of regional disparities in the field of agriculture. The analysis of the series of production and economic indicators showed that, instead of the expected convergence of the development of agriculture in the individual regions of Slovakia, the regions diverged in the monitored period. What is contrary to the European Union's endeavor to ensure convergence of regions under the regional and cohesion policy for 2014-2020.

The paper addresses an essential aspect, related to the economic efficiency of sunflower production, i.e. the selling price (lei/kg). This situation is determined by the multiple possibilities for the recovery of sunflower seeds, depending on which producers can negotiate different levels of the selling price on the basis of the quantitative and qualitative parameters of the seeds, which may be stipulated in the recovery contracts or which may be taken into account at the time of sale on the open market, to various beneficiaries. It should be noted that Romania is the main grower and producer of sunflowers in the European Union (about 24% of the total area harvested and about 25% of total production respectively). Addressing the subject, aimed to highlight the differences between the 8 development regions existing at national level, in Romania. The price is characterized by a multiannual national average of 1.39 lei/kg, with limits of 0.99 lei/kg for the West Region in 2014 and 1.61 lei/kg for the South Muntenia Region at the level of 2016. If we look at the indicator in the light of its evolution over time, we see the existence of fluctuating trends.
