Storage of the foods obtained by plant and animal production is as important as their cultivation. Crops cultivated around the world lose 28-36% of total yield during the process from agricultural land to consumption. With the most of this loss occurs after harvest and harvest, it can be reduced by suitable machines and appropriate methods to be used. Niğde is in third place in the list of cities with the highest apple production in Turkey. In addition, it is seen that the potential of the region to benefit from solar energy is quite high with 8.02 hours of daily sunshine duration and 1550-1800 kWh m-2 total solar radiation values. In line with the information given, Niğde province stands out as an important opportunity for apple drying processes using solar-powered drying methods. In this study, suitable drying methods that can be used for agricultural products in general and methods that can be used in Niğde province have been investigated and with the using the information obtained from previous studies related to the region its examined that the solar drying system and machines that can be developed for the province of Niğde are specified.

Drying is an essential process in the preservation of agricultural products. Various drying methods are employed to dry different agricultural products. Each method has its own advantages and limitations. Choosing the right drying system is thus important in the process of drying agricultural products. Drying reduces the possibilities of the contamination by insects and microorganisms so that product is prevented. An experimental study was performed to determine the Sensory Evaluation of pineapple slices subjected to drying in open sun drying, cabinet tray dryer at 50oC, 60oC and 70oC and hot air oven at 50oC, 60oC and 70oC with osmotic treatment indicated that T0 (Control), T1(50oBrix) and T2 (60oBrix). The result obtained showed that a product osmo- treated 60obrix at 50oC tray dried shows the better texture, flavor, color, taste and overall acceptability.

In the year before the accession to the European Union, the Slovak agricultural sector reported a loss of SKK 2.4 billion and following a profitable year, the earnings were reduced by SKK 2.8 billion. The situation was caused by a number of reasons, namely reduced sales of agricultural products, damage resulting from adverse weather effects (cold weather, hail, drought and  swine fever), as well as widening of the price gap compared to the year before (increasing input prices in agriculture and decreasing purchase prices of agricultural products, especially in livestock production). Legal entities and natural persons experienced mixed business success. While 51% of legal entities made profit, the figure rose to 76% in the group of natural persons. Both the agricultural cooperatives and trading companies performed with a loss. The loss per hectare of agricultural land (a.l.) was substantially lower in the case of business companies. Natural persons - private farmers were profitable over the period. The gap between the profitable and loss-making enterprises has widened. Some 60% of profitable enterprises owned by legal entities made only a small profit below SKK 0.5 million. The loss-making performance was typical for more productive areas of Slovakia. This was related to stronger effects of adverse climate in 2003.

The article is devoted to substantiating the prospects for increasing the marginal volumes of agricultural production for export in the next four years. Two scenarios of such production are considered: 1) expansion and 2) intensification of the use of land resources. As part of the development of the first scenario, an analysis of the distribution of unused agricultural land, including arable land, by federal districts was carried out. Also, based on the forecast of the introduction of additional annual volumes of acreage in the subjects of the Federation, the calculation of additional volumes of agricultural production, which can be expected in the next four years, was carried out. The analysis of data on the increase in the yield of export-oriented crops over the past five years has been carried out, in the framework of the second scenario, the calculation of the projected additional yield due to the intensification of agriculture is presented. The results of the study indicate that the intensification of agriculture will have the greatest impact on the growth of production and export of agricultural products in the near future.

The article, based on a comprehensive analysis of regulations, doctrinal approaches and case law, substantiates the understanding of the term "agriculture" in terms of purpose (use) of land. Direct analysis of regulations revealed that agricultural land is land provided for agricultural production, agricultural research and training activities, location of relevant production infrastructure, including infrastructure of wholesale markets for agricultural products, or intended for these purposes. In turn, the purpose of the land is the permissible limits of land use by citizens and legal entities (acquirers of such a right) established by law and specified by the relevant body (which transfers such land into ownership or use). The basis for determining the purpose of the land is its belonging to the appropriate category. The main criterion, for example, to distinguish agricultural production (agricultural activity) from other activities is the use of agricultural land as the main (basic) means of production. As a result of the study, it was concluded that the term "agriculture" can be understood in its broad and narrow sense. In a broad sense, the term "agriculture" is the use of land for commercial agricultural production, farming, personal farming, subsidiary agriculture, individual and collective gardening, haymaking and cattle grazing, for research and training purposes, provision of services in agriculture, placement of infrastructure of wholesale markets for agricultural products, as well as other activities on agricultural land, depending on the activities provided by law and the constituent documents of the economic entity. In a narrow sense – this is the purpose of agricultural land. The understanding of the term "agriculture" as the purpose of agricultural land is used by the court in resolving disputes.

In the Non-Black Earth Zone of Russia, since the 90s of the last century, the number of tractor and other agricultural machinery has sharply decreased. If in 1990 there were more than 30 thousand tractors of various capacities in the Tver region, then by 2020 there are 4 thousand tractors left in collective agricultural organizations, and approximately the same number of tractors are in private farms. The reduction occurred more than 8 times, with the remaining equipment having an average age of over 12 years. The renewal of tractor equipment in recent years has been happening at a rate of 1-2% per year, at the same time, 7-8% of the remaining tractors are written off annually. Directly connected with such dynamics is the reduction of acreage, which decreased by about 10 times, to 120 thousand hectares. And only in recent years there has been an increase in cultivated areas to 278 thousand hectares. At present, 551 thousand hectares of agricultural land are used for the production of agricultural products, that is, from 2,575 thousand hectares. Half of the agricultural land is arable land. More than 300 thousand hectares of arable land are idle, overgrown with forest, bushes, hogweed. The age of vegetation, forests on abandoned arable land reaches 10 years. In the near future, most of these lands may be completely decommissioned.

Pulsed Laser Irradiation

Due to the limited availability of agricultural land, pH sensing is becoming more and more important these days to produce efficient agricultural products. Therefore, to fabricate eco-friendly and disposable sensors, the black carbon, which is called biochar, is formed by irradiation of a UV pulsed laser having a wavelength of 355 nm onto wood and applying the resulting material as a pH sensor. The surfaces of three types of wood (beech, cork oak, and ash) were converted to the graphitic structure after UV laser irradiation; their morphologies were investigated. In addition, since the content of lignin, an organic polymer, is different for each wood, optimal laser irradiation conditions (laser fluence) needed to form these woods into pH sensors were considered. Depending on the degree of oil-like material generated after laser irradiation, a disposable pH sensor that can be used from one to three times is fabricated; due to the environmental characteristics of wood and biochar, the sensor shows high availability in that it can be easily discarded after use on agricultural land. After that, it can be used as filter in soil. Our wood-based pH sensor sensitively measures sequential changes from pH 4 to pH 10 and shows a very linear change of △R/R, indicating its potential for use in agriculture.

Some studies have shown that the estimation of global sunshine duration can be done with the help of geostationary satellites because they can record several images of the same location in a day. In this paper, images obtained from the MODIS (Moderate Resolution Imaging Spectroradiometer) sensors of polar orbiting satellites Aqua and Terra were used to estimate daily global sunshine duration for any region in Turkey. A new quadratic correlation between daily mean cloud cover index and relative sunshine duration was also introduced and compared with the linear correlation. Results have shown that polar orbiting satellites can be used for the estimation of sunshine duration. The quadratic model introduced here works better than the linear model especially for the winter months in which very low sunshine duration values were recorded at the ground stations for many days.

AbstractThe Hohokam grew maize as early as 300 B.C. Common beans were introduced by Estrella phase (100 B.C.-A.D. 100) and cotton was cultivated by the following phase (A.D. 100-300). Sahuaro and mesquite seeds supplemented agricultural products especially when crops failed. The Hohokam apparently harvested two plantings per year. Opuntia seeds were eaten when crops failed and sedge seeds were consumed during optimal conditions for growth of all local vegetation. Pollen analysis suggests cholla buds were eaten and that there was continual expansion of agricultural land from Sweetwater through Gila Butte phases. Coniferous timbers were incorporated into houses during the last phase (Sacaton, A.D. 1100-1200) of the occupation of Snaketown.
