A Comparative Study of Crop Evapotranspiration Estimation by Three Methods with Measured Crop Evapotranspiration in Konya Plain
(Selçuk Üniversitesi, 2019) Yavuz, Duran; Süheri, Sinan; Amarkai, Peter Addo
Evapotranspiration values are one of the basic data used in the planning, design, construction and operation of irrigation facilities. The irrigation water needs of several plants are calculated by using various empirical equations based on meteorological data and the system is designed according to the month in which the highest irrigation water is needed. The aim of this study is to compare ETc of several crops calculated with different ETc estimation methods as of FAO56-Penman-Monteith, Hergeaves - Samani and Radiation Equation with determined ETc values obtained from previously conducted researches in Konya. In the study, five commonly cultivated crops in Konya Province such as maize, sugar beet, sunflower, potato and wheat were considered. In most of the cases, it was found that radiation equation produced higher ETc values than the measured ETc values in the researches conducted at the region. As a result of this study, Penman-Monteith was close to most of the values obtained from other studies and therefore remains a highly recommendable method for estimating ETc for considered plants in Konya.
Seasonal and Annual Changes of Some Climate Factors in Different Areas of Loose Dairy Cattle Barns
(Selçuk Üniversitesi, 2022) Suci, Elif Şahin; Uğurlu, Nuh
This study was conducted to determine the changes of some climatic factors throughout the year in different barn areas in a loose system dairy cattle shelter. For this, digital temperature-humidity meters were placed on different shelter areas, and measurements were made for a year. By developing a different and new model as well as the maximum, minimum and average values in a certain time period in five different areas of the shelter, the temperature and humidity values were categorized into specific groups (stressful, slightly stressful, suitable, etc.) and it was determined how long the animals were exposed to what temperature and humidity values. According to the results, the animals were exposed to temperatures between 5-25 °C for approximately 80% of their time in the spring and autumn seasons, 40% in the winter season, and 50-55% in the summer season. At optimum temperatures (10-20 °C), the animals spent approximately 50% of their total time in spring and autumn, 20% in summer, and 15% in winter. Animals were exposed to heat stress (ti?32 °C) for only 5-7% of their total time in summer and to cold stress (ti <-5 °C) for only 6-14% of the time in winter. Dairy cattle were found to spend 60% of their annual total time in the appropriate temperature range and approximately 33% of the annual time in the optimum temperature range. Animals were exposed to heat stress and cold stress for about 6-7% and 2-3%, respectively of their total time per year. Animals were exposed to the relative humidity in the range of 40-90%, for approximately 50- 60% of their total time throughout the year. According to the results of the research, it was determined that open system shelters planned to protect animals from cold in winter and heat in summer, not create a significant climatic stress on animals.
Environmental Mitigation Through Irrigation Management in Sugar Beet Production
(Selçuk Üniversitesi, 2020) Topak, Ramazan; Kalender, Mehmet Akif
This study assesses the greenhouse gases (GHG) emissions of sugar beet production under different irrigation and nitrogen fertilizing strategies. This manuscript is an evaluation of the production inputs used in a research carried previous on sugar beet and its conversion into GHG emissions equivalent. This paper evaluates the potential for environmental mitigation, including the reduction of total GHG emissions from agricultural inputs in sugar beet production by managing irrigation and nitrogen fertilizing. In this context, the nine treatments based on three different irrigations (full irrigation, conventional deficit irrigation, partial root drying irrigation) and three nitrogen fertilization strategies (full nitrogen, partial deficit nitrogen, moderate deficit nitrogen) were assessed. The results of evaluation showed that DI-N1 strategy can reduce irrigation water and nitrogen use up to 25% compared to control treatment (FIN). In addition, this strategy saved 25% of electricity consumption use for irrigation. The analyse of pollution in this study led to very important findings: more environment-friendly irrigation and fertilization practices by using less water and nitrogen have a considerable potential for environmental mitigation in sugar beet production.
The Response of Dry Bean to Water Stress at Various Growth Cycles in a Semi-Arid Region
(Selçuk Üniversitesi, 2021) Yavuz, Nurcan
Poor irrigation management is resulted from some reasons such as lack of information relevant to the crop water use. That kind of information is necessarily prerequisites for both planners and producers to obtain irrigation program to minimize the yield losses under water stress conditions. A two-year, 2013-2014 growing season, field experiment was performed to determine the response of dry bean to the water deficiency in different growth stages at Konya plain of Turkey. The study was organized as randomized complete block design with three replications. Vegetative (V), reproductive (R), and pod filling-maturation (P) three plant growth cycles as were examined with including rain-fed total eight irrigation treatments were researched. A 100% crop water requirement (VRP) was considered full-irrigation treatment. Irrigation was not performed during vegetative, reproductive, and pod filling-maturation cycles or during a combination of those stages in other treatments. In results, depending on the irrigation treatments, actual evapotranspiration (ETa) for 2013 and 2014 varied from 104 to 544 mm and from 110 to 558 mm, respectively. The average crop coefficients (Kc) among the years were 0.75 for vegetative, 1.01 for reproductive, and 0.82 for pod filling-maturation stages. Depending on irrigation time, as decreasing the irrigation water resulted reducing seed yield. It was obvious that higher seed yield as well as yield components obtained full irrigation at entire growing season, which was preferable. An alternative to full irrigation in whole growth stages particularly in areas with insufficient water resources, performing full irrigation till initial of the filling-maturation cycle and then ending irrigation can be highly recommended as ideal, as it resulted water saving of 38%, and rise 27% in irrigation water use efficiency (IWUE) as well as 20% seed yield loss by comparison to full irrigation.
Identification of drought-tolerant pumpkin (Cucurbita pepo L.) genotypes associated with certain fruit characteristics, seed yield, and quality
(ELSEVIER SCIENCE BV, 2019) Seymen, Musa.; Yavuz, Duran.; Dursun, Atilla.; Kurtar, Ertan Sait.; Türkmen, Önder.
Climate change-associated drought stress in plants is one of the major environmental factors that cause a reduction in plant growth, development, and productivity. Therefore, an improvement to obtain superior genotypes that are highly adaptable to arid and semi-arid conditions remains the main objective of the future breeding efforts. In this context, the present study was conducted to determine the genotypic differences among 16 inbred lines and 4 commercial cultivars of pumpkin associated with the parameters such as certain fruit characteristics, seed yield, and seed quality in irrigated and drought conditions. In the growing season of pumpkin, the amount of irrigation water applied was 402.6 mm in 2017 and 425.4 mm in 2018. In all the evaluated parameters, the examined genotypes exhibited a wide range of significant differences between the irrigated and drought conditions in both the years. Moreover, a significant positive correlation was observed between seed yield and fruit number, seed-thickness and plant height, and 1000-seed weight and seed size. In terms of seed quality, 1000-seed weight was determined to be a prominent parameter. The results of the present study demonstrated that these relationships imply a significant potential for the selection of genotypes with superior performance in both conditions. Furthermore, principal component analysis (PCA), performed considering the Eigenvalues, indicated that the yield and quality components could be explained strongly by the PCA analysis in irrigated as well as in drought conditions. Finally, the inbred line G9 was observed to be the most superior genotype in terms of yield and fruit number in both irrigation and drought conditions; therefore, this inbred line is envisaged to be evaluated in future breeding studies and to be included in future hybrid programs in order to develop drought-tolerant cultivars.
Effects of different irrigation interval and plant-pan coefficient applications on yield and quality parameters of oil sunflower grown in semi-arid climatic conditions
(SPRINGER HEIDELBERG, 2019) Yavuz, Nurcan.; Çiftçi, Nizamettin.; Yavuz, Duran.
Sustainability of plant production activities and improvement of irrigated lands in arid and semi-arid regions totally depend on efficient use of available water resources. Such an efficient use of water resources can be provided through assessment of water-yield relationships and identification of proper irrigation programs, schedules, and operational principles. There are no studies carried out to determine water-yield relations of oleic-type sunflower plants grown over large areas in Konya plain. In this study, different irrigation intervals (S) and crop-pan coefficients (Kcp) were used in drip irrigation of sunflower plants in Konya which is located at the Middle Anatolia in Turkey. The primary objective was to determine the effects of irrigation levels and intervals on yield and quality parameters of sunflower plants. Experiments were conducted in 2013-2014 growing seasons in 3 x 5 factorial design with 4 replications. Three different irrigation intervals (S-5:5, S-10:10, and S-15:15-day) and five different crop-pan coefficients (Kcp(1.25):125% of pan evaporation, Kcp(1.00):100% of pan evaporation, Kcp(0.75):75% of pan evaporation, Kcp(0.50):50% of pan evaporation, and Kcp(0.00):rain-fed without irrigation) were used in this study. In an average of 2 years, the greatest seed yield (5481 kg/ha) was obtained from S(10)Kcp(1.25) with the greatest water consumption (748.7 mm). As compared with S(10)Kcp(1.25) treatment, about 25% decrease was observed in yield of Kcp(0.75) treatments irrigated at 5- and 10-day intervals. Such a decrease was identified as 15% in Kcp(1.00) treatments irrigated at 15-day intervals. Therefore, for optimum seed yields from sunflower plants grown in Konya plain, irrigation intervals should not exceed 10 days. Also, crop-pan coefficient should be taken as 1.00 for high seed yields. Again, in an average of 2 years, irrigation water use efficiency (IWUE) of the treatments varied between 0.70 and 3.70 kg/m(3) and water use efficiency (WUE) values varied between 0.53 and 0.75 kg/m(3). The average yield response factor (k(y)) was identified as 1.14. Since the value is greater than 1, it was concluded that sunflower plants were sensitive to water deficits under Konya conditions.
Effects of drainage and land consolidation on sustainable agricultural productivity: Changes in kos 6th section
(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2019) Celebi, Muhittin.; Egilmez, Samet.
The main obstacles to the sustainability of agricultural productivity in arid and semi-arid areas are the tendency of conditions to salinization, wind erosion and degradation of plant water balance. In this study, it was aimed to determine the usage level of the potential of the land consolidation, which is applied within the context of the KOS 6th Section project in semi-arid Konya plain, in preventing the wind erosion. It was also aimed to determine the changes created by the closed drainage on some soil parameters in Konya-cumra-Turkmencamili between 1998-2001-2016 period, and the reduction rate in salt level. For this purpose, the analysis results of soil samples obtained from 0-30 cm, 30-60 cm and 60-120 cm depths during the planning phase before the establishment of the drainage in 1993 and after the establishment of the drainage in 2001 and 2016 were compared; furthermore, the positions of the blocks established during the land consolidation were examined in terms of the prevailing wind direction leading to erosion. With the drainage application, during the period between 1993 and 2016, the highest and lowest EC values of the soil samples decreased respectively from 2.43-25.0 mmhos/cm to 0.680-2.880 mmhos/cm in 0-30 cm depth and from 2.63-50.00 mmhos/cm to 0.584-4.190 mmhos/cm in 30-60 cm depth. The periodic decrease rate of salt level in soils according to years was higher in the first 3 years between 1998 and 2001 than those in the range of 2001-2016. It was determined that during the land consolidation, 78 blocks (79%) were not planned in a perpendicular position to prevailing wind directions. With this block layout, since it is not possible to establish a windbreak facility in such a way that it is serially and perpendicular to the prevailing wind direction that will cause problems in the future, the effective protection distance of windbreaks will partly fall from 12 trees' height to 8 trees' height and below.
Effects of hourly, daily and seasonal variation of hazardous gases and climatic factors on the welfare of sheep housed in solid-floor confinement barns
(SOUTH AFRICAN JOURNAL OF ANIMAL SCIENCES, 2019) Seyfi, S. Uzal; Ilhan, F.
Ambient air quality in livestock buildings is one of the most important factors affecting environmental pollution and global warming. Carbon dioxide (CO2), methane (CH4), ammonia (NH3) and hydrogen sulphide (H2S) are among the most hazardous gases in terms of human and animal health. The aim of this study was to determine the effect of hourly, daily and seasonal variations in the levels of hazardous gases, such as CO2, CH4, NH3 and H2S in a solid-floor confinement sheep barn; as well as the effect of climatic parameters, temperature (T), relative humidity (RH) and air flow (AF) on animal welfare. The correlation between hazardous gases and climatic factors in the barn was also determined. The study was carried out on a sheep farm between July 2012 and June 2013 in Konya (Turkey) where few data are currently available on this subject. Climatic data were measured at intervals of five minutes at different points during this study, while hazardous gases were measured at the same intervals during the experimental periods (10 days for each season). All data were analysed by one-way analysis of variance (ANOVA) and Tukey's method was used to reveal intergroup differences. Cross-bilateral correlation between all data and different time periods was examined. There were significant differences between hourly and daily mean values of CO2, NH3, T, RH and AF. CO2 and NH3 levels showed a significant correlation with T and RH. Unfortunately, H2S and CH4 were below the level of detection in the study. Reducing the formation of these harmful gases, which have negative effects on animal production and cause environmental pollution, will be carried out with new sheep barn designs that take into account ambient air quality appropriate for animal welfare.

(MEDWELL ONLINE, 2010) Uzal, Selda; Uğurlu, Nuh
The design of appropriate housing for cow comfort is important to increase animal production. This study was carried out to determine annual time budget and shelter area usage of cows between 2006 and 2008 in Konya-Turkey. Behavior of animals (n = 24) and barn area usage of dairy cattle was investigated freestall dairy housings. Behavior of cows was observed by recording during 24 h of a day with video cameras mounted at suitable places in barn parts. The animals behaviors related to barn area choice were investigated and seasonal variation of dairy cattle housing area usage observed during to 10 days for each season. Annually average barn area usage of dairy cattle were determined as 3.33 h cubicle, 12.22 h courtyard, 1.30 h scraped alley, 6.09 h feeding, 1.06 h watering and milking area in freestall housing. The effect of season on the time budget activity of dairy cattle was important. Lying behaviors of dairy cattle decreased from 50.9% (summer) to 40.5% (winter). Dairy cattle spent their time about >50% in open area as courtyard. The annually time budget of dairy cattle were found as 45.4% lying, g, 13.7% standing, 25.4% feeding, 1.7% drinking, 9.9% walking, 2.6% milking and 1.3% other behaviors in the research. The present study showed that well design of courtyard, resting and feeding areas very important for animal production and welfare as well as cattle management.
Comparison of Energy of Irrigation Regimes in Sugar Beet Production in a Semi-Arid Region
(Pergamon-Elsevier Science Ltd, 2010) Topak, Ramazan; Süheri, Sinan; Acar, Bilal
This study analyzed the effect of three levels of drip irrigation in sugar beet (Beta vulgaris L) production in the Middle Anatolian region of Turkey. Two deficit irrigation treatments 75% and 50% of measured soil water depletion were compared with a full irrigation control treatment. In this paper, root yield, NEY (net energy yield), EEP (efficiency of energy production) and EWUE (energy water use efficiency) were investigated. Energy consumption of irrigation was found to be about 60% of total energy input in sugar beet production under full and deficit irrigation treatments. It was found that sugar beet had the highest EEP value (6.29) under the partial deficit irrigation (representing 75% of full irrigation). However, it was observed that full and severe deficit irrigation (representing 50% of full irrigation) treatments had a lower value. Results of this study indicated that the partial deficit drip irrigation technique can be applied in sugar beet production. In practice, deficit irrigation technique can reduce irrigation water use up to 25% compared to full irrigation technique. In addition, partial deficit drip irrigation technique may save 11.2% of total energy inputs, 16.1% of irrigation energy inputs, 21.2% of total fuel use and 25% of fuel use in irrigation.
Water Quality and Uniformity in Trickle Irrigation Systems: A Case Study of Antalya, Turkey
(Asian Journal of Chemistry, 2009) Acar, B.; Yavuz, F. C.; Topak, R.; Uğurlu, N.
The clogging of emitters is a common problem in trickle irrigation systems. Partial or complete clogging adversely affects uniform water distribution, as well crop yield. Despite the quantity of research cited in previous studies about the quality treatment and distribution uniformity of irrigation water, the problem still present. The research was performed to determine effects of water quality on emitter clogging and uniformity of water for I I different trickle systems installed at greenhouses in Antalya, Turkey. The results showed that the pH varied from 7.14 to 8.11. Electrical conductivity (EC) varied from 432 to 866 mu hos/cm and irrigation water used in 6 trickle systems (55 %) it was lower than the 750 mu hos/cm and had low hazard effect on greenhouse plants. In water samples used in five systems (45 %), had moderately hazard. The uniformity coefficient (UC) varied between 62.2 and 95.1 %, the average of 88 %. The UC values show excellent uniformity in 63.6 % of the systems, good in 27.3 % and poor in 9.1 %,
Determination of the Salt Tolerance of Some Barley Genotypes and the Characteristics Affecting Tolerance
(TUBITAK, 2003) Bağci, Seydi Ahmet; Ekiz, Hasan; Yilmaz, Ahmet
The Salt (NaCl) tolerance of 8 barley genotypes was investigated. Plants were grown hyroponically in Hoagland solution at 5 different NaCl concentrations. Germination percentage, shoot and root length, shoot and root dry weight, salt tolerance percentage, and K and Na concentrations in the shoots and roots were evaluated. Salt tolerance percentage, which is calculated from the germination percentage and dry weight production, was the most reliable criterion. On the other hand, with some exceptions, high K concentration and K/Na ratios were other potential criteria. Erginel-90 and WBELT-10 showed high levels of tolerance: and Obruk-86, Anadolu-86, Kiral-97 and Karatay-94 showed medium levels. Tokak-157/37 and Hamidiye-85 were the most susceptible genotypes to NaCl.

(EUGEN ULMER GMBH CO, 2002) Uğurlu, Nuh; Acar, Bilal; Topak, Ramazan
The objective of the present experiment was set to investigate the effects of temperature variations on egg production, feed intake, number of cracked eggs, egg shell strength, egg weight, body weight, mortality rates, and manure moisture content in caged layers. The experiment was conducted in three different environmental temperatures, namely cool, temperate, and warm regions. The mean temperatures obtained from these three regions were measured as 21.4 degreesC, 22.6 degreesC, and 27.6 degreesC, respectively during the experiment. As the environmental temperatures increased egg production was decreased. With in creasing environmental temperature from 21.4 degreesC to 27.6 degreesC, feed intake of layers decreased from 113.3 g/hen to 96.5 g/hen. The relationships with environmental temperature. egg production and feed consumption were significant (P < .01). Increasing of environmental temperatures resulted in lower egg weights. An adverse relationship between temperature and number of cracked egg was observed. Body weights were higher in the cool region in comparison to warm region.

(Kluwer Academic/Plenum Publ, 2002) Gezgin, Sait; Dursun, Nesim; Hamurcu, Mehmet; Harmankaya, Mustafa; Önder, Mustafa; Sade, Bayram; Topal, Ali; Soylu, Süleyman; Akgün, Necdet; Yorgancılar, Mustafa; Ceyhan, Ercan; Çiftçi, Nizamettin; Acar, Bilal; Gültekin, İrfan; Işık, Yusuf; Cevdet, Şeker; Babaoğlu, Mehmet
Boron toxicity may occur in semi-arid regions due to high levels of B in soils, in the ground water, in fertilisers or in irrigation water (U.S. Salinity Lab. Staff, 1954; Nable et al., 1997). Boron availability is affected by soil properties, principally pH, salt content, organic matter, lime, soil texture and exchangeable cations (Keren and Bingham, 1985; Sakal and Singh, 1995; Rahmatullah et al, 1999). According to Wilcox and Durum (1967), the minimum B concentration in irrigation water for a given crop species that does not reduce yield or lead to injury (symptoms) ranged from 0.3 to 1.0 mg B I¹ for sensitive crops, to 1.0 to 2.0 mgl¹ for semi-tolerant crops, and 2.0 to 4.0 mgl¹ for tolerant plant species.

Arpa genotiplerinde tuz toleransının fizyolojik analizlerle belirlenmesi
(Selçuk Üniversitesi Fen Bilimleri Enstitüsü, 2012-01-25) Yeğin, Zeynep Gül; Yorgancılar, Mustafa
Bu araştırmada bazı arpa genotiplerinin tuza toleransları araştırılmıştır. Çalışmada S.Ü. Ziraat Fakültesi Tarla Bitkileri Bölümünde ıslah çalışmaları sonucu geliştirilen Soylu-10 ve Soylu-11 ile Konya ilinde yaygın olarak yetiştirilen Anadolu, Konevi, Larende ve Tokak çeşitleri olmak üzere 6 arpa genotipi kullanılmıştır. Tohumlar perlit içeren saksılara ekilmiş ve çıkıştan sonra farklı NaCl konsantrasyonları (0, 25, 50 ve 75 mM) içeren half hoagland çözeltisi ile sulanmıştır. Onuncu hafta sonunda bitkilerin morfolojik ve fizyolojik parametreleri incelenmiştir. Araştırma sonuçlarına göre; bağıl su içeriği (BSİ), klorofil değeri (KD), stoma iletkenliği (Sİ), Potasyum (K) içeriği ve köklerde kalsiyum (Ca) içeriği bakımından kontrol grubu bütün genotiplerde daha yüksek değerler vermiştir. Prolin miktarındaki artış; arpa bitkisinin tuz stresine olan tepkisi ve stres koşullarının verdiği zararı en aza indirmek amacıyla oluşturduğu savunma mekanizmasının harekete geçmesi olarak nitelendirilmiştir. Na ve Cl değerleri bütün genotiplerde tuz konsantrasyonları arttıkça bitki ve köklerde artış olmuştur. Araştırmada bitki ve kök uzunluğu, bitki ve kök kuru ağırlığı, bitki ve kök yaş ağırlığı sonuçları tuz stresini belirlemede önemli bir kriter olarak belirlenmiştir. Fotosentetik verim üzerine yapılan araştırmada tuz stresinin altı genotipe etkisi olmadığı belirlenmiştir. Genotipler tuz stresi altında farklı dayanıklılık mekanizmaları geliştirmişlerdir. Bazı genotipler yüksek tuz uygulamasından az etkilenirken bazıları daha etkilenmiştirler. Sonuç olarak yapılan çalışmada çeşit adayı olan arpa hatlarının tuza tepkileri belirlenerek, tolerans sınırları ortaya konmaya çalışılmıştır. Yapılan çalışmalar sonucunda 10. ve Soylu-11 tuza hassas olduğu belirlenmiştir. Bu iki genotipin ekim alanlarındaki tuz oranları düşük değil ise bunların ekiminde ekonomik karlılık görülmemektedir. Tokak 157/37 çeşidi de sonuçlara göre hassas bir çeşit olduğu belirlenmiştir. Larende, Anadolu 98 ve Konevi çeşitleri de tuzlu alanlarda kullanılabilecek en uygun çeşitlerdir.
