Rice is one of the strategic crops in Egypt and the world. Therefore, the main objective of the research was to modify and develop the seed drill to suit the cultivation of rice and add the digger to make a path for the cultivation area to direct the irrigation water. The modification and development were done in the workshop of the Rice Mechanization Center (RMC) in Kafr El-Sheikh Governorate, and field experiments were carried out on the rice variety "Sakha Super 300" with the planting seasons 2021 and 2022. The field experiments were carried out using the modified hill seed drill under four different planting forward speeds, namely, 2.55, 4.01, 6.11, and 8.38 km/h.; three different hills spacing between within the row, namely, 12.5, 15.5 and 17.5 cm; and three different cell volumes of feeding rollers namely, 354, 428 and 509 mm3 with a fixed depth of 6 mm. The results showed that when the forward speed of cultivation increased, the field capacity increased and power requirements, and a decrement percentage in field efficiency and energy consumption at any given load for modified hill drill. The minimum values of grain yield (3.45, 3.41, and 2.94 Mg/fed) were obtained at planting forward speed of 8.38 km/h., for grain cell volume of 354 mm3 under 12.5, 15, 17.5 cm hill spacing, respectively. However, the maximum values of grain yield (4.79, 4.74, and 4.34 Mg/fed) were obtained at planting forward speed 2.55 km/h., and grain cell volume of 509 mm3 under 12.5, 15, and 17.5 cm hill spacing, respectively.

This research focuses on two main aspects, each equally important for tourism actors. First, we analyzed the impact of the Covid-19 pandemic on the rural mountain tourism in Romania and whether the resilience and sustainability test was passed. The second aim of the research was to identify solutions for the relaunch and development of the rural mountain tourism in Romania. Several research methods have been used to meet our objectives, such as analysis, synthesis, comparison, observation or documentary research. The quantitative research methodology used is limited to the questionnaire-based survey. The questionnaire contained 16 questions and was administered by telephone, between 15-30 March 2023 was addressed to a number of 100 respondents including owners or administrators of classified accommodation units in the mountain area. The analysis of the results shows that the pandemic had a neutral to positive effect for tourism in the mountain area and that, for the most part, the resilience and sustainability test was passed. We consider that this study is very useful for tourism entrepreneurs, for local and central public authorities and the conclusions and recommendations extracted from the questionnaires can suggest valuable ideas for the relaunch and development of the rural mountain tourism in Romania.

The study looked into the use of input in sesame production with the view on seeing the returns to its production in Ringim Local Government Area, Jigawa State, Nigeria. Data were obtained from 100 randomly selected farmers using the multistage sampling technique. Descriptive statistics, net farm income and regression model were used in data analysis. The result showed that the mean age of the respondents was 38 years with secondary education been most popularly attained. The respondents had a household size of 3 persons cultivating a farm size of 3.5ha with experience of 8 years on average in sesame production. The results also reveal net farm income and return on naira invested of N 46,190.59 and 1.54 respectively, an indication of a profitable enterprise. The semi-log functional form gave the best fit based on the normal econometric criteria with coefficient of multiple determination of 0.312 implying that about 31 percent of the variation in yield of sesame was explained by the specified explanatory variables. It also revealed that there was under utilization of all the production inputs under consideration. It is therefore encouraged that more of the limiting factors (farm size, quantity of seed and quantity of organic manure) observed be put into cultivation.

The transition to highly productive and environmentally friendly agricultural farming is one of the priorities of the Strategy for Scientific and Technological Development of the Russian Federation. In the current conditions of sanctions policy, the need for a large-scale transfer of agriculture to organic farming increases. The purpose of the article is to develop methods and tools for the development of organic farming on an innovation and investment basis to ensure sustainable development of rural areas. The article presents the evolution of views and methodological approaches to studying the relationship between organic agriculture and sustainable development. The global trends in the development of the organic products market are studied, the dynamics of organic production in Russia are presented both in general and in the context of grain crops, legumes and vegetables. It has been empirically revealed that the bulk of the harvest of organic grain crops remains on the domestic market, and most of the leguminous crops are exported. The article examines global trends in the development of the organic products market. Methodological approaches and principles for the transition to the Organic 3.0 concept, aimed at intensifying the growth of organic product production, have been developed. Promising forms of organizing organic farming have been substantiated and conditions have been created for increasing the efficiency of organic production on an innovation-investment basis, taking into account regional specifics. The economic, social and environmental role of organic farming as a driver of sustainable development in Siberia is substantiated. Methods and tools have been developed to improve the state policy for the development of organic farming in rural areas of Siberia, including subsidies, subsidizing the purchase of certified planting materials, developing competency standards, and improving the regulatory framework. The practical significance of the results lies in the development of theoretical and methodological approaches and methodological tools for sustainable development of rural areas, based on the introduction of advanced organic farming technologies, as well as targeted mechanisms for stimulating organic production. organic farming, sustainable development, innovation and investment support,

The investigation of the causes and consequences of food loss and waste has been extensively explored in the literature, given its significant impact on both the local community and the national economy. This paper suggests various comprehensive approaches concerning food loss and waste (FLW) in Romania, considering the broader European context of the FLW phenomenon based on a bibliographic study, a statistical approach of the causes dynamics analysis and a system-based approach leading to an integrated view of the phenomenon. In order to accomplish this purpose, we have used statistical material originated from national and European statistical institutions and we have processed it using direct observation and interpolation. Our objective was to identify various factors contributing to food loss and waste throughout the agrifood chain and analyse their impact on the FLW phenomenon. The findings revealed that the primary factors contributing to food waste are associated with economic aspects. This study serves as a foundational step for subsequent research endeavours.

Soil is one of the Earth's most precious resources and is essential to sustaining life on our planet. However, soils are increasingly subject to degradation due to intensive agricultural practices, deforestation, pollution and climate change. Conserving soil and preventing soil degradation has become imperative in our efforts to ensure food security, protect biodiversity and maintain healthy ecosystems. Impact strategies are essential to maintain soil fertility, prevent soil erosion and degradation, conserve water and help reduce greenhouse gas emissions. In this context, the aim of the research is to explore the impact of key conservation strategies and practices that can be adopted to protect soils and ensure their long-term sustainability. Data were collected from public institutions, from the official National Institute of Statistics, NIS, website Tempo-Online and the National Land Improvement Administration. Implementing soil conservation strategies is essential to protect the environment, ensure the sustainability of the food system and maintain the ecological balance of our planet. Soil conservation is a vital component of sustainable development and environmental protection in Romania. Through effective implementation of conservation strategies and stakeholder involvement, the country can protect the essential resource of soil with a positive impact for future generations. The strategic elements and techniques discussed in this article contribute to maintaining ecological balance and conserving natural resources for future generations.

The purpose of this study was to analyze the dynamics of Gross Domestic Product (GDP), Export (E) and Import (I) in Romania and also in its agro-food sector in the last decade 2013-2022 and to quantify the relationships between these macroeconomic indicators using the data provided by National Institute of Statistics. The methodology used in this study included; fixed basis and structural indices, growth rate, statistical econometric modeling using regression equations, coefficient of correlations, coefficient of determination, comparison and illustrative methods. In 2022 versus 2013, Romania's GDP accounted for Euro 285,884.8 Million (doubled), export raised by 85.51% and reached Euro 91,944 Million, imports accounted for Euro 126,034.07 Million (2.27 times higher) and the deficit of trade balance reached Euro -34,101 Million, being 5.92 times higher. The regression equations quantified the impact of the determinants on GDP as follows: an increase in E value by one unit will determine an increase by 3.5086 units of GDP; an increase by one unit of I will determine a growth by 2.1058 units of GDP; an increase by one unit of NE will shrink GDP by 5.10849 units. In agro-food sector, the situation was the following in 2022 versus 2013: GDPA reached Euro 12,864.81 Million (+66%). EA accounted for Euro 11,959.97 Million (2.26 times higher), IA reached Euro 13,248.61 Million (2.7 times higher), NEA attained Euro -1,288.64 Million (9.4 times higher compared to 2015 level). The regression assessed the impact of the determinants on GDP as follows: an increase in EA will raise GDPA by 0.8668 units; an increase by one unit of IA will determine a growth by 0.7034 units of GDPA; an increase by one unit of NEA will shrunk GDPA by - 1.2343 units. To balance the ratio between E and I with a beneficial impact on NE and GDP, Romania has to intensify exports and diminish imports, to increase production and quality of the exported products, to identify the products which should be purchased from abroad to cover the needs on the domestic market, to offer more subsidies to producers, to extend its commercial partners on the external market and better negotiate the trade transactions.
