In this study, the combined infrared-hot air dryer develops and optimize in Agricultural Engineering laboratory, faculty of agriculture, Tanta University, Egypt. Thin-layer modelling of sweet potato slices drying under infrared (IR) and hot-air drying (HAD) were used to estimate the drying coefficients. The initial moisture content of the freshly harvested sweet potato was 79 – 81 % (w. b.). 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) with a constant air velocity of 1.2 m. s-1 were using. The experimental measurements included sweet potatoes slices moisture content, air temperature, radiation intensity, and quality changes of the dried sweet potato. Three different thin layer drying models (Lewis's model and Henderson & Pabis's and Logarithmic model) were examined for describing the changes of moisture content during the drying process. The results show that, the Coefficient of determination R2 and Standard error, SE. for The Logarithmic model recorded R2= 0. 99 and SE= 0.122 were considered more proper for describing the drying kinetics and predicting the changes in moisture content of sweet potatoes more than the Henderson and Pabis's were model recorded R2= 0.94 and SE= 0.51 and Lewis's model were recorded R2= 0.96and SE = 0.241. The results show that, the moisture ratio of sample slices decreased when the radiation intensity and the drying air temperature increased. Meanwhile, the drying constant of Logarithmic model (kLog) increased with the increasing of radiation intensity and air-drying temperature and the decreasing of slice thickness. The diameter and thickness shrinkage percentage occurred with all treatments, while slightly increasing with infrared radiation. The rehydration ratio ranged from 3.95 to 5.53.

This research aims to determine the cost and profitability analysis of farmers’ greenhouse cut flower (carnation, gerbera and lisianthus) production in Antalya. In 2018, the cut flower production in Antalya province accounted for about 56.04% of Turkey’s cut flower production. Snowball sampling methods were used to select the cut flower growers and the sample size was calculated as 53 farmers. The data obtained from the enterprises’ cut flower production was obtained by face-to-face interviews with the farmers using the producer questionnaire developed by these researchers. The data for the study was obtained in 2018. According to the study’s conclusions, the most important cost factor in the greenhouse cut flower production process in the enterprises interviewed was the variable cost. The variable cost share of the total production cost in carnation production was 56.96%, 59.44% in gerbera production, and 64.03 in lisianthus production. The fixed cost percentage was 43.04%, 40.56% and 35.97%, respectively. As for cost items, the most important elements were permanent labour, fertiliser, seedlings, pesticide and land rent. The relative profit value, which better measures the return of production activities, in greenhouse cut flower production was calculated as 1.47 in carnation enterprises, 1.60 in gerbera enterprises and 1.26 in lisianthus enterprises.

In the context of climate change, there is a growing need to study the impact of environmental factors on plant life. This, in turn, will allow the reasonable use of agricultural techniques, to form high-yielding crops, and increase crop productivity. The following variants of tillage and irrigation technologies were included in the research scheme (i) conventional tillage without irrigation; (ii) no-till without irrigation; (iii) no-till with drip irrigation system; (iv) no-till with system of subsoil drip irrigation. Corn yield varied significantly from the studied factors of cultivation technology. The highest productivity of 12.1 t/ha was obtained under no-till with a system of subsurface drip irrigation and 12.0 t/ha under no-till with drip irrigation system. During the statistical processing of the obtained experimental data, no significant difference between the studied variants was found. Carrying out an economic analysis of corn growing in the arid climate of the Southern Steppe of Ukraine testifies to the high efficiency of application of the new tillage and irrigation systems in the cultivation technology. The application of no-till with drip irrigation system allowed to obtain grain with a cost of 3.72 UAH/t, to obtain a profit of 50.13 UAH/ha with a level of production profitability of 112.2%. It should be noted that the use of no-till with system of subsoil drip irrigation led to slightly lower indicators of economic efficiency of corn cultivation, under which the level of production profitability was 109.0%.

In order to study the effect of sex and pre-slaughter weight on the performance of Irish Landrace pig carcasses, 400 pigs with equal number of barrows and gilts were selected and fattened. After fattening, the pigs were divided into two groups according to sex. Then, 20 gilts were selected using weighing into 4 groups with a pre-slaughter weight 90 kg, 100 kg, 110 kg and 120 kg. Similarly, 20 barrows were divided for 4 groups with same pre-slaughter weight 90 kg, 100 kg, 110 kg and 120 kg. All gilts and barrows from eight experimental groups were slaughtered and their carcasses were measured and then sampled to determine slaughter parameters. It was found that in general, gilts had higher carcass weight at pre-slaughter weight 90, 110 and 120 kg, higher chilled carcass weight at pre-slaughter weight 120 kg, higher carcass length and length of bacon halves at pre-slaughter weight 120 kg, higher thickness of longest back muscle and meat content at pre-slaughter weight 100 kg.Barrows had a higher fat thickness above the 6-7 thoracic vertebrae, the fat thickness in the buttocks, the fat thickness in the withers at pre-slaughter weight 100 kg.

This study evaluated the use of nitrogen in wheat crop, in terms of Agronomic Efficiency (AE) and Partial Factor Productivity (PFP). The experiment was conducted in the specific conditions of the Banat University of Agricultural Science and Veterinary Medicine of Timisoara (BUASVM), Timis County, Romania. Nitrogen (N) was provided on the basis of ammonium nitrate, in the range 0 - 250 kg a.s. ha-1, in 11 experimental variants (T1 to T11). The AE index varied between 14.631 (T2) and 9.138 (T11), with a maximum (27.211) corresponding to the N75 dose (T4). The PFP index recorded decreasing values from 90.497 (T2) to 16.725 (T11). The AE index variation in relation to N was described by the polynomial equation of degree 4 (R2 = 0.975, p <0.01), and the AE index variation according to Y was described by a polynomial equation of degree 3 (R2 = 0.722, p = 0.0233). In relation to the calculated progressive increase yield (PY) the AE variation was described by a linear equation (R2 = 0.780, p <0.001). The PFP index variation in relation to N was described by a polynomial equation of degree 3 (R2 = 0.994, p <0.001), and in relation to N and Y, as simultaneous influence, was described in statistical safety conditions (R2 = 0.885, p = 0.0144).

The study identified farming households’ livelihood activities and reasons for their multiplication, determined the underlining factors for livelihood diversification, and examined the militating constraints faced. The study was conducted in the poverty-ladened Ejigbo Local Government of Iwo zone, Osun State. A multi-stage sampling procedure was employed for sampling households for data collection. A total of 130 households were selected for data collection from the household heads. Collected were subjected to descriptive analysis and logit regression analysis. The results showed that the mean farm size per household was 1.2±0.6 hectares just as the mean annual income was estimated to be N105,394±26,546. The off-farm livelihood activities identified include trading (28.4%) and carpentry (27.2%), among others. The foremost reasons for off-farm diversification were limited agricultural income (75.2%), large family (63. 3%), and poverty (60.6%). Indicated as influencing the household likelihood of off-farm livelihood diversification are household size (b=0.33), farming experience (0.049), and income (b=1.01). More so, households' livelihoods were constrained mainly by the unfavorable market price of a commodity (68.8%), inadequate credit access (64%) as well as insecurity (62%). It was concluded that trading and artisanal activities represented major off-farm livelihoods and their likelihood of exploration is chiefly underpinned by the household size, income, and farming experience. Rural markets development is recommended for capacitating the households to substantiate their farm and off-farm livelihoods.

The article presents forecast modeling of foreign trade between Ukraine and Romania by separate groups of agro-industrial goods. Indicators were forecast for three years (2022-2024) based on actual data for eleven years (2011-2021). Five trend models (exponential, linear, logarithmic, polynomial, and power) were constructed for each indicator and only one with the highest value of the reliability of the approximation R² was selected. The constructed trend models indicate a positive trend in 2022-2024 for preparations of grains, cocoa and cocoa preparations, sugar and sugar confectionery, animal or plant fats and oils; in 2023-2024 – for meat and meat preparations, alcoholic and non-alcoholic beverages, vinegar. At the same time, the forecast models indicate an increase in imports of tobacco and its industrial substitutes in 2023-2024, a decrease in imports of cereals over the same period, an increase in imports of other mixed foodstuffs in 2022-2024. Of the nine selected models, six are polynomial, one is power, one is logarithmic, and one is exponential. Two of them have a very high degree of reliability of the approximation R² (>0.9) and, accordingly, a high probability of forecast prediction.
