Ali Kaan Yetik | Burak Şen
Efficient use of water, one of the most critical life elements in the world, is becoming more and more important day by day. With the continuous increase in population and with climate change problems occur in terms of both consumption rate and usage patterns of water resources. It is becoming increasingly important to apply and research methods that can solve these problems all over the world. One of these solutions is the “Water Harvesting” method, which goes back many years. Water harvesting can be defined as the accumulation of runoff generated by precipitation to provide water for human, animal or crop use. While it is possible to see the use of the technique with roof and farm systems in micro-catchment dimension; wadi-bed and off-wadi (diversion) systems are used in macro-catchment dimension. In agricultural production, which uses a significant part of water resources, most of the rainwater falling into arid and semi-arid regions where production continues, goes away before could using efficiently by evaporation or flow. For this reason, the use of water resources becomes mandatory by using traditional irrigation methods in agricultural lands. With the water harvesting technique, after storing rain water, it can be held to be applied to crops. Hence the method since there will be no losses due to evaporation or flow, it will increase the total amount of irrigation water and reduce the pressure on water resources. Except for the protection of water resources, its role in preventing soil erosion is also seen as one of the main benefits of the method. In general, when the appropriate method is selected according to the appropriate geography, water harvesting has low inputs and is not difficult to apply. With a few exceptions, it does not require the use of pumps or energy input to deliver or deliver harvested water. In this study, information is given about the main elements, different usage areas and techniques of water harvesting.

Muhammed Taşova | İsmail Naneli
With the increase in the population in the world and in our country, the energy requirement related to consumer demands is constantly increasing. In our country, although wind, sun, etc. energy sources are used in energy production, fuels of fossil origin (coal, natural gas, oil etc.) are used more in energy production. Renewable energy sources, which are alternative due to the decrease in fossil fuel reserves, negative environmental effects and inability to meet the energy needs in the future, come to the fore. In this study, Turkey Statistical Institute (TUIK) according to the 2015-2019 year data, Sakarya at the central and districts in cultivation areas for cultivated of using the amounts of maize and wheat product (da) average waste, dry matter, and volatile dry matter, methane and energy their potential has been determined. As a result of the calculations, it has been determined that the maize sap waste amount has the highest 25695.68 tons of waste and 201197.15 MJ energy potential in Adapazarı district in 2017. Among the wheat stalk wastes, in 2017, Geyve district had the highest 269.95 tons of waste and 2113.72 MJ energy respectively.

Gülistan Erdal | Hilmi Erdal | Adnan Çiçek
This paper studied the effect of livestock support policies applied in Turkey by a emprical study. The study was carried out based on the analysis of the data collected through surveys with a total of 478 livestock enterprises in the TR83 region (including Amasya, Çorum, Samsun and Tokat provinces). The enterprises included in the survey study were grouped into three categories by the number of their animals. Binary Logistic Regression Model was applied in order to define the policy-based support payment utilization probabilities of the enterprises and the factors affecting them. It was determined that approximately 45% of the enterprises cannot utilize livestock supports. The most utilized support items by the enterprises were determined as calf support, support per animal, forage plant support and raw milk support. A total of 65% of the enterprise owners think that the support amount per animal is insufficient, but regard the mentioned support item as the most important factor for improving animal presence. The utilization rates vary in terms of enterprise scales on the other hand. The support utilization likelihood of medium-scale enterprises is 3.1 times higher than small-scale enterprises, and this likelihood is 1.7 times higher for big-scale enterprises when compared with medium-scale enterprises. The study recommends that some regulations are needed in support of policies to enable a better improvement in animal presence and a homogenous distribution of support payments.

This study was carried out between 2017 and 2018 to determine physical and chemical influences of two drying methods (drying on wooden fruit drying trays and drying cloths), two harvesting periods (commercial / physiological maturity and late harvest), and two harvesting methods (harvesting by hand and shaking) on dried fruit samples of Hacıhaliloğlu and Kabaaşı cultivars. Titrable acidity, browning level, total phenolic content, antioxidant activity (ABTS), color (L*, a*, b*), pH, humidity and water activity (aw) parameters of dried fruit samples were examined. Results indicated that different harvesting periods, methods and drying methods significantly affected almost all fruit quality parameters. L value was higher in apricots dried on trays than dried on the cloths. L* values of dried apricots ranged from 27,13 to 54,74. Similarly, moisture content and water activity values were also found to be lower in apricots dried on wooden fruit drying trays than dried on clothes. When chemical parameters were examined, it was observed that phenolic compounds and total antioxidant contents decreased with fruit ripening. The effect of the applications on drying efficiency was not determined as significant, on the contrary, the individual weights of the dried apricots harvested at the late period were found significantly higher and the number of dried apricots per kilogram was lower. As a result of the study, it was concluded that in sun-dried apricot production, harvesting at late period and the drying on trays positively affected various quality parameters.

Hydraulic conductivity is an essential base for applied research in soil and water management, landscape, and environmental disciplines. Saturated hydraulic conductivity (Ksat) is one of the most important soil physical properties, which is considered in the planning of irrigation and drainage and predicting other soil hydrological processes. However, it has been frequently reported that measurement of Ksat is laborious, time-consuming, and expensive due to its high spatial variability and this has motivated researchers to develop indirect methods such as pedotransfer functions (PTFs) for developing Ksat-database in regional and national scales. In this study, eight Ksat studies with the PTFs in Anatolian soils were reviewed. PTFs were evaluated regarding their type, predictors used, and their performance. The majority of studied PTFs were developed on alluvial, colluvial, and alkaline soils in semi-arid and semi-humid climates. Multiple linear regression (MLR) and artificial neural networks (ANNs) have been common PTFs, and soil texture, bulk density, organic matter content, and pH have been common predictors used with these PTFs. Root mean squared error (RMSE), mean absolute error (MAE), and coefficient of determination (R2) were the commonly used criteria in the verification and validation of the PTFs. Studies on the use of Ksat and PTFs are inadequate, and researches are still needed to be able to use it nationwide and can develop an adequate database. According to the results of PTF studies, the highest R2 and correlation coefficient (r) values belong to the Rosetta and MLR types of the PTFs, respectively. The lowest RMSE value was obtained with the equations in which the physical and chemical soil properties were used together as input data for PTFs. In addition, it has been noted that the soil morphological properties should be used as input data in PTFs studies, especially in Ksat estimation.

This study aimed to evaluate the effect of compost from chicken manure, NPK fertilizer and the mixture of both fertilizers on agronomic parameters of four varieties of cassava (Yacé, Bonoua, Six mois and Alleda agba) in Côte d’Ivoire. The field experiment was carried out under a randomized complete block design with three replicates on a ferralitic soil during two season-cycles. The results showed that the different fertilizers stimulated plants growth and tuberous roots production. The highest number of stems (3) and leaves (66) was obtained with the mixture of NPK and compost applied on the variety “Bonoua”. All varieties that received the compost mixed with NPK produced more leaves with a dominance of the Bonoua variety (65.57). The highest number of tuberous roots (5.58), the heaviest weight per root (6.13 kg) and the highest yield (61.37 t/ha) were obtained while using the mixture of compost and NPK as fertilizer and “Bonoua” as variety. Thus, mixing compost from chicken manure and NPK can be recommended to improve cassava productivity in Côte d'Ivoire on a ferralitic soil.

The aim of this study was to investigate the effects of organic copper supplementation (0, 5, 10 and 20 mg/kg) in the commercial diet on performance, egg quality and haematological parameters in laying quails. In this 10-week trial, a total of 80 laying quails, aged 22 weeks, were randomly distributed among four experimental groups. Each experimental group contained four replicates of five female birds each. The addition of organic copper to the diets did not statistically affect egg production, egg weight, egg mass, feed conversion ratio, damaged eggs, egg shape index, Haugh unit, and blood parameters except neutrophils and mean corpuscular haemoglobin. Compared to other groups, body weight change was decreased by the addition of 20 mg/kg organic copper, and feed intake was decreased by the addition of 10 mg/kg copper in the quails. The addition of 20 mg/kg of organic copper to the quail diets significantly decreased the eggshell breaking strength and eggshell weight, while it significantly increased the eggshell thickness compared with the control group. The neutrophil and mean corpuscular haemoglobin were increased by the addition of 10 and 20 mg/kg organic copper, respectively, with compare to other groups. It can be said that up to 10 mg / kg of organic copper can be added to commercial quail diets, but its addition at 20 mg/kg negatively effects on some blood parameters as neutrophil and mean corpuscular haemoglobin in quails.

This study was carried out to determine the plant protection practices of the garlic growers in Gaziantep province. For this purpose, a survey consisting of 20 questions and based on simple random sampling method was conducted with 81 growers in each of the districts of Araban, Oguzeli, Yavuzeli, Central, Nurdagı, Nizip and Karkamış districts in 2018. The data evaluated and expressed as percent ratio. According to the findings from the surveys, garlic growers stated that they preferred pesticide dealers suggestions for the selection and determination of doses of pesticides used in pests and diseases, they also stated that the price and expiration date were not an important factor in the selection of pesticides. In addition, it is found that growers avoid using the same pesticide continuously against same diseases and pests, they do not make any changes in there commended pesticide doses, pesticides leave residues on the products, they paid attention the time between the last application and harvest. It has been reported that the use of protective clothing and mask during the application by the growers is relative, they do not use pesticides as a mixture, they apply different processes to empty pesticide boxes. It was determined that garlic growers prefered chemical control and did not have knowledge about the concept of biopesticides.

In this study, it is aimed to determine sugar beet production in Konya province, operation of factories in the region, the situation of farmers, privatization, production structure of sugar beet and the problems based on it. For this purpose, data were collected by questionnaires from 175 producers, who were selected according to Probability-Based Sampling method, from the producers operating in the cooperatives registered in the Association of Beet Cultivators Cooperatives (Pankobirlik) in Ilgın district of Konya. According to the findings, the difficulties encountered in production were listed as high irrigation cost of sugar beet (87.4%), difficulty in combating diseases and pests (77.7%), excess labor demand compared to other products (74.3%), and insufficiency of water in the region (72.0%) in sugar beet production. In addition, about 77% of producer’s state that product prices are low. Approximately 60% of the producers in the region have stated that they are against the privatization of sugar producing factories. When the results are evaluated, it is necessary to take into consideration the costs in determining sugar beet purchase prices and to include sugar beet production within the scope of support to reduce production costs. In addition, it is considered necessary to take essential steps by considering producer opinions on privatization and to review sugar policies.
