Farmers' subjective satisfaction can be a basis for the improvement of any development programs in agriculture. This paper intended to evaluate the farmers' satisfaction with Participatory Coconut Planting Project (PCPP) and predict its governing factors using a statistical model. This study utilized secondary and cross-sectional data from a current study in the literature to quantify the farmers' perception and its factors to PCPP that is organized by Philippine Coconut Authority (PCA). Hence, the study involved 145 coconut farmers who participated in the PCPP to increase their productivity and income level. The data were summarized through descriptive calculations and determine the association of variables with the aid of regression analysis. Results of the study have depicted that coconut farmers, on average, are satisfied with the different functions of PCPP in regard to their farming activities. This implies that farmers are being assisted with their needs and concerns involving the production process. The regression model has revealed that younger farmers are more likely satisfied with the project. In addition, farmers with higher incomes tend to appreciate the PCPP functions. Moreover, farmers who experienced some training and a member of some agricultural associations are more satisfied with PCPP. Conclusively, young and active farmers who involved themselves in government programs in agriculture are more productive, efficient, and appreciative of farming projects. Hence, it is suggested that PCPP must be strengthened to reach out to more coconut farmers to improve their production, income, and their lives.

Smart agriculture has the potential for economic benefits through increased agricultural productivity, cost efficiency and market opportunities through increased communication; and environmental benefits as this will in turn, lead to greater food security, profitability and sustainability. This article presents the practices and challenges to smart agriculture among commercial arable crop farmers in Southwest, Nigeria considering the forms of digitalization in use, as well as the frequency of usage, period of usage, and challenges to the usage. We randomly sampled 45 commercial arable crop farmers across the southwest states in Nigeria. We made use of Structured questionnaire to extract needed information from the respondents. The data obtained were analysed with descriptive statistics. Our findings showed that the forms of digitalization used by agricultural firms include mobile phone (100%), cloud computing (56%), software (58%), remote sensing (40%), digital marketing (52%), and GIS (35%) while the average period of usage of digitalization was 10years. Our findings also revealed that the main challenges to the use of digitalization are high cost of procurement and installation (93%), low awareness of current state of digitalization in agriculture (84%), limited technical knowhow (78%), poor power supply (67%), and high cost of energy (62%). Although evidence at short-term revealed that smart agriculture has the potential of tackling key development issues such as food insecurity, poor output, poverty, and unemployment; the study showed that there is a need to enlighten agricultural firms of the benefits of smart agriculture, as well as plan and invest on sustainability of digitalization in agriculture to harness its full benefits/potentials.

The most effective way to enrich the food resources necessary for humanity is to increase agricultural production per hectare, which can be achieved by introducing new cultivars and high-performance hybrids, by improving the cultivation technology, by calculating the need for nutrients in each crop, and by taking into account the crop, the expected productions and the natural fertility of the soil. This paper aims at evaluating the fertilization plans made on a farm in the town of Curtici, Arad County, Romania, in the main agricultural crops: wheat, barley, maize, and rape. During an annual vegetation cycle, there are several pheno-phases that are characterized by a differentiated consumption of nutrients, which determines the application of different types and doses of fertilizers. The farm is equipped with a series of tractors and agricultural machines with which they work the 600 ha of land and provides various mechanization services to different physical and legal people in the area. The main activity of the farm is the cultivation of cereals. The identified soils were chernozem, preluvosol and alluviosol, i.e., soils that have good and very good natural fertility. Following the calculations made, it turned out that the nutrient requirements were 57.08 t/ha of nitrogen, 78.33 t/ha of phosphorus and 29.80 t/ha of potassium. In wheat, the largest quantity in nutrients is in nitrogen, which plays an essential role in the growth phase, after which the requirement of nitrogen decreases. The productions obtained were different depending on the year, the climatic conditions and the doses of fertilizers applied: in wheat, 7.5 t/ha in 2020 and 8.0 t/ha in 2021; in grain maize, 8.0 t/ha in 2020 and 8.2 t/ha in 2021, with an average of 8.1 t/ha; in barley, between 8.1 t/ha in 2020 and 8.1 t/ha in 2021; and in rapeseed, 3.5 t/ha in 2020 and 3.6 t/ha in 2021. It was found that the application of fertilizers in the recommended doses depending on the crop, on plant growth phase, and on the plant, needs increases the production in all four crops in the study. In conclusion, the correct establishment of fertilization plans is the most useful tool in establishing the recommended fertilizers, taking into account both the natural fertility of the soils on the farm, of their plants, of their nutritional needs, of the expected productions and of the expenses necessary to purchase the fertilizers (whether organic or mineral fertilizers). Thus, making early economic decisions related to what we need to cultivate, on what surfaces, to the works involve in each crop, to the quantities of necessary fertilizers and treatments helps purchase the necessary products in due time and at better prices. This is how one saves considerable price differences, resulting in lower production costs and higher profits.

This paper analyses the effect of inflation, gross domestic product (GDP) growth, and average salary on unemployment in Lithuania for the period from 2001 to 2021. First, the theoretical analysis is performed to review the links between inflation, GDP growth, average salary, and unemployment. Considering that the theoretical analysis reveals the effect of three macroeconomic factors, i.e., inflation, GDP growth, and average salary, on unemployment, the methodology of the research is described. It relies on the multiple regression model and its estimation using ordinary least squares (OLS). Econometric analysis reveals that only one out of three macroeconomic factors, i.e., GDP growth, has a statistically significant effect on unemployment and this effect is negative (based on the sign of the regression coefficient). In addition, to address the autocorrelation problem in the regression model, a lagged unemployment variable is included to the model, and it shows a statistically significant positive (based on the sign of the regression coefficient) effect on unemployment. The future study could only cover the agricultural sector since this sector is important for Lithuania and the macroeconomic indicators of this sector are unique compared to other economic activities or general indicators of Lithuania.

This paper examines the specific roles of men and women at various phases of fishing activity. There were a total of 266 fisher respondents randomly selected from six identified fishing sites in Leyte, Philippines. Data were gathered through face-to-face interview using a pre-tested questionnaire. Both descriptive statistics and independent sample t-test were carried out to analyze the primary data gathered. Based on the findings, men primarily take part in decision makings pertaining to fishing activity such as fishing time, place, and quantity of fish catch to sell. They also are the in-charge in the preparation of the fishing paraphernalia and the ones who sell and bring the fish catch to their preferred marketing outlets. Meanwhile, women played vital roles in cooking the food for fishing activity and the ones who compute, record and keep the earnings from fishing activity.

The aim of this study is to investigate different time-dependent drying and moisture content under different infrared (IR) and hot-air drying levels and product quality. In this experiment it was used a hybrid drying system to minimize energy consumption during the drying operation and to reduce environmental impact by reducing product loss in wastes. Three different levels of sweet potato slices thickness (1, 3, 5 mm), were pre-treated by dipping into a solution of 0.5 % sodium meta-bisulphite and 1% citric acid for 30 min. Four different levels of infrared radiation (0.861, 0.973, 1.039 and 1.161 kW.m-2) and three different levels of air-drying temperature (45, 55 and 65°C) were using. The changes in moisture content during the drying process with a constant air velocity of 1.2 m. s-1 were noticed. The moisture content decreased with drying time. To obtain the desired moisture content from (6.92% to 7.52%), the drying time for 1mm and 0.861 kW.m-2 was 165,150 and 105 min while for 5mm and 1.161 kW.m-2 was 330, 270 and 240 min at 45, 55 and 65 °C, respectively. The total energy consumption decreased from 14.685 kW. h to 5.72 kW. h as the radiation intensity increased from (0.861 to 1.161 kW.m-2).

The study was conducted to determine the carbon footprint of poultry farms. Breeder farms were included in the study. The fuel and electricity bills from farm, house size and age, flock size and number of flocks per year, and manure management were all collected. The methane, nitrous oxide, and carbon dioxide equivalent emissions were calculated, as well as the effect of these gases on breeder farms productivity, as well as determining the carbon footprint of breeder farms to reduce the negative effects of greenhouse gas emissions. In addition to providing necessary information on breeder’s chicken performance and advising poultry farmers on the relative merits of different climatic conditions to help set standards for different production traits. The experiments were conducted of closed farms in the city of Mansoura during the period from May 2019 to December 2021 and the capacity of the farm was 43,300 breeders’ chickens. The results showed that the amount of methane gas produced from the farm was 1.76 ton ch4 yr-1 and nitrous oxide gas was 0.13 ton n2o yr-1 for manure management. Thus, the total emissions of manure management are estimated at 81.65 tons of co2-eq. The amount of greenhouse gas emissions for diesel is 5.23 tons of co2-eq. The amount of greenhouse gas emissions (GHG) for the electricity used in the farm is 0.15 tons of co2-eq. In the end, the total amount of emissions produced from the farm is 87.04 tons of co2-eq. In the end, the total amount of carbon dioxide equivalent emissions generated from Egypt’s farms is 271.8 (kiloton co2-eq).

This study discusses the result of a life cycle assessment (LCA) for three Egyptian aquaculture farms categorized as semi-intensive culture. The cradle-to-grave system was used to calculate the overall carbon footprint of fish unit production. The major data came from a study of three feed factories in Egypt, which included a wide range of feed manufacturing and agricultural practises in order to reveal the varied greenhouse gas (GHG) emissions. Pre-farm, farming, and post-farming were the three stages of the life cycle assessment. Feed manufacture, which was primarily tied to the production and processing of raw materials, was the largest source of GHG emissions for all three processes. GHG emissions were also produced during the transport of raw materials to the factory. GHG emissions were also produced during the transportation of raw materials to manufacturers, as well as feed from factories to fish farms, via ship or road. Energy consumption in feed factories varies due to variances in design technology and manufacturing efficiencies. Feed conversion ratios (FCR) have a significant influence on GHG emissions since more feed is required to produce one kilogramme of fish. The kind of packaging material and energy utilised in the factories had an impact on GHG emissions, as each type had a distinct emission factor (EF). Aside from fingerling production, there are direct and indirect N2O emissions, as well as post-farming operations like packaging, ice serving method, and customer transportation. The conclusions of the investigation revealed that According to the results of the study, the emissions linked with the three farms varied greatly. Hanafy farm had the greatest emissions, with 3.265 kg CO2e/kg fish and 50.917 tonnes CO2e/Season, followed by Hashim farm with 2.259 kg CO2e/kg fish and 45.829 tonnes CO2e/Season, and finally Aly farm with 2.223 kg CO2e/kg fish and 38.864 tonnes CO2e/Season.

The paper aimed to analyze cereals production and price at farm gate, also farm inputs prices (seeds, fertilizers, plant protection products, fuel and herbicides) in the EU in the period 2016-2021 and also partially in 2022 in order to identify the trends in the main cereals producing countries France, Germany, Poland, Romania, Italy, Spain and Hungary and to propose a few alternatives to farmers how to adapt to climate change for sustaining production. Eurostat data regarding cereals production and price at farm gate and also prices for farm inputs were used, graphically illustrated including trend regression equation and coefficient of determination. The results pointed out that EU cereals output accounted for 272.6 million tonnes in 2022, being by -8.2% lower than the peak of 2019. Wheat and maize production is 128.19 million tonnes and, respectively, 55.1 million tonnes, meaning lower levels than before. Cereals output declined in the main producing countries: France, Germany, Romania, Spain, Italy, Hungary, but increased in Poland. High temperatures, heat waves, severe and long droughts, low precipitations were the main causes related to climate change. Cereals price at the farm gate increased, and also production costs went up due to the raise in farm input prices which started since 2021 and exploded in 2022. High price for diesel, seeds, fertilizers, plant protection products, herbicides, were recorded compared to their levels in 2015. The highest increase of producer's price ranged between +60.7% in Hungary and +31.8% in Spain. In Romania it was +40%. Compared to 2015, in 2021, the growth rate of farm inputs price was: +15.8% for diesel, +10.8% for seeds, +9.8% for fertilizers, +5,13% for herbicides and +3% for plant protection products. In the future, farmers have to increase production rethinking cereals structure, using more high potential varieties and hybrids, resistant to drought, diseases and pests; to extend biodiversity and use crop rotation to preserve soil nutrients; to implement technologies with fewer inputs and conservative agriculture for assuring the sustainable development of cereals production, protecting environment and preserving biodiversity.
