The objective of this study was to obtain new regression formulas for optical equipment Fat-O-Meat’er and OptiGrade-PRO in pig carcass classification in Romania. The estimation of lean mean content in pig carcasses by means of SEUROP system and following fair payment based on the weight and composition of the carcass pigs in the main objective of classification. Dissection of four main cuts (shoulder, loin, ham, belly) of pig carcasses (n = 145) were performed. The measurement of backfat and muscle depths using probes were taken from the carcasses within 45 min. after slaughter of pigs. Lean meat content estimated using different methods and determined from dissections was equal (56,3 % ). There were calculated new regression formulas using the multiplied regression analysis. Correct regression formulas for classification equipments have a big importance. The requirements on accuracy of regression formulas are laid out in the Commission Regulation No 3127 / 94 and means of dissection according to the method by Walstra and Merkus (1996)

This paper analyzed the plantain value chain in Ondo State, Nigeria. It identified the various actors in the plantain value chain and their functions, mapped out the various segments, their linkages and the overall plantain value chain and identified the value added at each segment of the value chain. One hundred and seventy seven respondents were selected using multi-staged sampling technique and interviewed using structured questionnaire, informal interview and observation techniques to obtain the primary used. This was analyzed using functional and analysis. Result from the functional analysis, amongst other characteristics, showed that there were eight major actors or segments in the plantain value chain in Ondo State, Nigeria. They are the input suppliers, farmers, processors, marketers, consumers, transporters, cooperative societies and farmers association. This paper concluded that plantain farming is still lowly mechanised and processing has not been fully developed to explore the various value addition options available in this sector. More value can still be added to the product and more upgrading could still be done in the chain. More actors can also take advantage of the prevalence of plantain in the state. In addition, the government and private research institutions should pay attention to the training needs of the farmers so as to properly harness the comparative advantage that the state has above others states in the production of plantain.

Mining activities have the potential to affect the health of the ecosystem and reduces its ability to provide goods and services needed for human welfare and the environment. The importance of a healthy environment for future generations is a pillar of sustainable development. To be more environmentally friendly, more mining operations carried out in a manner that minimizes its impact on the surrounding environment. A number of management strategies and technologies are being developed and used by the mining industry to reduce the environmental impact of mining. One of the potential considerable environmental pollutions may occur in the mining sector is pollution due to hazardous wastes and toxic (it’s called B3 waste ). Compliance with the Indonesian Government Regulation number 101 of 2014 has been a challenge for the coal mining company given the B3 waste management requirements are very detailed and rigorous. B3 waste management challenges become more complex than other business sectors because of the typical mining company-wide working area and the number of workers involved lots. The mining company must prepare a special strategy in the management of B3 waste to be able to adhere to all requirements. The study was conducted at Mining Company “X” in terms of the effectiveness of the management of B3 waste by using Regulation of the Governor of East Kalimantan, Indonesia number 05 of 2014 concerning Performance Rating Program Activity In Coal Mining Environmental Protection and Management. The purpose of this study are: (1) To determine and analyze the effectiveness of the Waste Management Policy B3 on Mining Company “X” is based on Government Regulation No. 101 of 2014; (2) To determine and analyze the added value of B3 Waste Management Policy in Mining Company “X” (it's called MC "X").

Landscape potential, reflecting the country's ability to provide some opportunities and prerequisites for the use to meet the needs of human society and long-term use along the lines of sustainable development, is considered as basic purposeful and value characteristic of the country. The aim of this paper is based on the analysis of natural conditions and landscape structure to determine the possibility of applying different forms of rural tourism in the Slovak Republic, namely the example region Tekov, which lies on the border of western and central Slovakia. Region Tekov is among the warmest regions of Slovakia. The results presented in this paper were processed using the method of scientific abstraction, landscape structure analysis methods investigated area based on the methodology of landscape-ecological planning and methods of SWOT analysis. Region Tekov occupies the territory of 48 municipalities with its total area of 776.58 km2 and a population 73637. The dominant presence in the region has agricultural areas (67% of the area of the territory). This is the type of agricultural land, which their natural condition and on the basis of favourable landscape structure offers opportunities and space for application activities related to rural tourism, namely walking, cycling, water sports, agro tourism, viticulture, hunting and winter sports, especially skiing. Strengths of rural tourism in the region are heterogeneous landscape structure with the preserved natural environment and favourable climatic conditions, a strong tradition in viticulture, apiculture, horticulture and the presence of ecologically stable elements with plenty of usable water resources.

The present study was carried out to evaluate the impact of NaCl on chlorophyll florescence in three ecotypes of sweet “basil” (Ocimum basilicum L.) i.e., Multan, Khanewal and Rajanpur. Four weeks old seedlings were treated by different concentrations of NaCl (0, 50, 100, 150, 200 mM). Results showed that the increasing salinity stress had a negative impact on QY (Quantum yield), NPQ (Non photochemical quenching) and OJIP in three ecotypes of Ocimum basilicum L. From the findings, it is obvious that salt stress had a slight inhibitory effect in the first week of salt treatment. Under saline conditions as compared to non saline conditions dark adopted leaves of Rajan pur ecotype have reduced fv/fm ratio in third week of salt stress but decreased with increasing levels of salt stress in other two ecotypes. Therefore, analysis of the results showed that sweet basil might tolerate a level of salt stress up to 150 mM of NaCl and chlorophyll fluorescence can be used as a criterion for assessing salt tolerance in sweet basil as well as helpful to screen which ecotype might tolerate better the salinity stress. Our findings suggested that basil can be cultivated on salt effected soils up to moderate level that can be of potential importance in Ocimum basilicum production.

In the context of post-harvest conservation, a diagnosis of the pineapple orchard and risk factors for alterations related to fruit marketing was carried out by conducting a cross-sectional survey in the three major pineapple producing areas and four main areas Markets (Adjamé-Yopougon-Abobo-Plateau) in the Abidjan district (Ivory Coast). A sample of 250 producers and 200 traders was surveyed. The objective was to describe the post-harvest practices and risk factors associated with the commercialization of pineapple fruit. The results showed that the producers are men (100%), mainly illiterate (78.03%) and have an average age between 46 and 60 years (55.1%). Eighty percent (80%) are small growers with orchards under 10 ha. The plant material used by all the producers in the studied areas is composed mainly of 94.13% of discharges and chemical pesticides are used 100%. The harvest is 81.76% manual, unsorted and packaged in bulk (81.77%). Thus only 5.86% recognize that post-harvest losses are due to microorganisms. Also the traders investigated are mostly women (87.1%) and illiterate (70.7%) with a majority of age between 20 and 45 years. 97.73% of the sellers do not protect the fruits during the sale while 22.22% of the sellers carry out a cross-stocking with other fruits. Of all the municipalities investigated, all traders do not recognize the action of microorganisms in the alteration of the fruits. In the absence of sound health education and locally adapted interventions, producers and traders do not pay particular attention to preventing the risk of alterations. This study identified post-harvest practices in Ivorian pineapple plantation and the risk factors for alterations related to commercialization in the markets.

The study analyses the changes of the fractional composition of potassium of the main soils of southern Ukraine – ordinary chernozem and southern chernozem under influence of irrigation and fertilization systems. The research was conducted in two stationary experiments, laid on chernozem ordinary (11-year of crop rotation) and on chernozem south (3-year multifactorial experiment). It is established that under the influence of irrigation in ordinary chernozem the sum of groups of potentially available potassium in a layer of 0-30 cm increases by 40.3 and 57.5% in comparison with rainfed conditions. The content of exchangeable potassium in chernozem usually varies considerably depending on the soil moisture (r = - 0.80). The norm of fertilizers – manure 200 t/ha + N200P200K60, introduced under the basic cultivation of the first crop rotation, in the aftermath after 11th year provides a positive balance of exchangeable potassium in ordinary chernozem even with a decrease in the initial content in 2.1 times. In the southern chernozem, the total amount of potentially available potassium is much lower than in chernozem ordinary: 19.0% in the layer 0-30 cm and from 45.5 to 52.6% with a depth of 120 cm. The distribution of the depth and direction of irrigation and fertilizer systems are similar to those of ordinary chernozem.

Increasing agricultural risks is a major challenge in economy and efficiency in the agricultural sector that affect income and production decisions of farmers and sometimes is a major obstacle in the sustainable development. Thus, the main purpose of study was to predict the management components in reducing the risk aversion coefficient (RAC) among maize farmers in Moghan plain (Iran). 278 farmers selected using multistage random sampling. RAC calculated through Safety First Rule model and predictive management components were determined by ordered logistic regression (OLR) by STATA software. Results revealed that the most of maize farmers (65.10%) were riskaverse. Also, results of OLR revealed that the probability of placing the farmers at higher levels of risk aversion increased significantly by increasing age, farming experience, farm input costs and facing with more agricultural risks; while increasing education level and farm income, better farm and technical infrastructure management and better risk-sharing management, the probability of placing the farmers at lower levels of risk aversion increased.
