Su hasadı teknikleri kurak alanlarda yağmur sularını biriktirerek su sıkıntısının ve kuraklığın etkilerini azaltmanın yanı sıra, toprak ve su koruma açısından da yarar sağlamaktadır. Bu çalışmada, yağışların yetersiz olduğu yarı kurak iklime sahip Güneydoğu Anadolu bölgesinde, sulama olanağı bulunmayan genellikle eğimli arazilere tesis edilmiş zeytin bahçelerinde toprak ve su erozyonu kontrolünü sağlamak amacıyla, Negarim mikro havza yağmur suyu hasadı tekniği uygulanmıştır. Bu çalışmada; yağmur suyunun bitkinin kök bölgesinde birikimini sağlamak amacıyla Negarim adı verilen mikro havzalar içerisine yerleştirilen plastik örtü, taş örtü, mikro-havza yüzeyinin sıkıştırılması ve kontrol konularından oluşan 36 adet mikro-havzanın toprak ve su erozyonuna olan etkisi değerlendirilmiştir. Araştırmada 2009-2010 yılları boyunca yüzey akış ve sediment kayıpları ile bitki gelişimi ölçülmüştür. Araştırma sonuçlarına göre yıllık ortalama yağışı 250 ile 400 mm arasında değişen deneme alanında, 2 su yılı boyunca meydana gelen ortalama maksimum yüzey akış 6201 L/parsel ile plastik örtü konusunda, ortalama minimum yüzey akış 810 L/parsel ile taş örtü konusunda belirlenmiştir. Ortalama maksimum sediment kaybı 1163 g/parsel ile yüzey sıkıştırma konusunda, ortalama minimum sediment kaybı ise 673,5 g/parsel ile taş örtü konusunda ölçülmüştür. Mikro-havza yüzeyi plastik örtü ile kaplı olduğundan erozyon kontrolünü en iyi şekilde sağlayan uygulama plastik örtü olarak saptanmıştır. Plastik örtü konusu en iyi yüzey akışı gerçekleştirdiğinden bitki boyu gelişimi yönünden ortalama 107,5cm uzunluk ile en iyi uygulama olmuştur. Sonuç olarak kuru koşullarda ve eğimli arazilerde üretimi yapılan zeytin bahçelerinde Negarim mikro havza su hasadı tekniğinin ağaçların büyüme ve gelişimi arttırmanın yanı sıra toprak ve su muhafazası açısından da yararlı ve uygulanabilir bir teknik olduğu sonucuna ulaşılmıştır.

Most of the non-irrigated areas in the southeast of the Harran Plain are irrigated by groundwater. The aim of this study is to determine the importance of 13 underground irrigation water sources operating in the agricultural areas of Ohali village in southeast of Harran Plain in Sanliurfa province in terms of some quality characteristics and irrigation. In this context, the waters belonging to 13 underground wells were analysed and examined in terms of irrigation water quality. According to the results of the analysis, the electrical conductivity of water samples was measured between 1127-4090 µS/cm. The SAR value of irrigation water was found to be between 1.05-3.41 and the %Na value was between 16.2% - 31.8%. In the evaluation made according to four different classification systems, in general, waters 6, 7, 8 and 9 were determined as the worst quality in all classification systems. These waters are described “unsuitable” irrigation water. Considering that the plants which have high water consumption such as cotton and corn are cultivated in the region, it is foreseen that if the necessary precautions are not taken, the salinity in the soil will increase and yield losses will be high. It is imperative that these areas, which cannot be irrigated within the scope of GAP irrigation project, be irrigated with clean water as soon as possible. However, an appropriate drainage system must be installed in the area.

North Sinai governorate is one of the largest desert areas in terms of intensity of agricultural extension work, In spite of efforts by state agencies to bring about agricultural development in the governorate, agriculture is still somewhat characterized by primitive traditional methods, making agricultural development rates almost indistinguishable, And with the scarcity of extension research carried out in North Sinai in the field of environmental SWOT analysis, It was necessary to conduct the study that is trying to analyze the current situation of agricultural extension in North Sinai governorate through identifying the strengths; weaknesses, opportunities, and threats (SWOT). A participatory SWOT analysis study using open-ended qualitative-type instrument was conducted; Research data were collected through personal interviewing questionnaire with 90 respondents representing 75% of the total extension workers in North Sinai Governorate, during the period from May till October 2018. The results showed that the most important strengths of these were that a large proportion of the extension workers are specialized in agricultural extension, more than half of the guides were from rural areas and the high job satisfaction degree among of the majority of the extension workers while the most important weaknesses were Weak budget and inadequate funding for extension work, Absence of job description for the extension workers, and Lack of financial and material resources. On the other hand the most important opportunities were Availability of research institutes in the governorate, NGO-Public Sector Collaboration. While the most important threats were Decreased investments targeting the agricultural sector in general and the extension system in particular, Poor Farmer Organization, Security instability in the governorate. Depending upon SWOT outputs, some relevant strategies were discussed to develop agricultural extension system in the governorate through some dimensions that uses strengths and opportunities to overcome weaknesses and to avoid threats or minimize their effects.

The aim of this study was to investigate the effects of solid and liquid vermicompost on yield and nutrient uptake of tomato plant. The study was carried out with three replications according to the experimental pattern of randomized plots in the plastic pots with the capacity of 3 kg under the greenhouse conditions of Plant and Animal Production Department of Cumhuriyet University. In the study, chemical fertilization was applied for comparison with solid and liquid vermicompost. Vermicompost doses were applied as 0%, 10%, 20%, 30% and 40%. In the study, tomato yield and nitrogen (N), phosphorus (P), potassium (K), iron (Fe), zinc (Zn), manganese (Mn), copper (Cu) concentrations were determined. The results have shown that 10% solid vermicompost increased dry matter production of tomato plant with 8,92 g pot-1. This application was followed with 7,04 g pot-1 dry matter production in 20% solid vermicompost application. The highest increase in P (0,27% P) and K (9,01%) concentration of tomato plant was determined in 40% solid vermicompost. However, the highest N concentration was determined with chemical fertilization (4,06%). Generally, it was determined that the solid vermicompost higher effect on the yield and nutrient uptake of tomato plant than liquid vermicompost.

The aim of this study was to evaluate the chemical composition and mineral bioavailability of T. tetraptera fruit pulp, an aromatic wild edible plant, using standard methods. The pulp were extracted from mature dried fruits obtained from plants at Awabo (5°30’14.2”N and 4°01’30.6”W) and Loviguié villages (5°48’24.5’’N and 4°20’15.8”W), all in south-eastern Côte d’Ivoire. The results of chemical analysis revealed that T. tetraptera fruit pulp contains carbohydrates (63.73±0.51%), crude protein (7.01±0.66%), crude fat (1.18±0.01%), ash (5.38±0.18%), fibre (11.78±0.02%), moisture (40.52±0.18%) and an energy value of 254.74±0.15 kcal/100g. Besides, the results showed a relative high amount of vitamin A (2.11±0.02%) and vitamin B9 (261.78±0.01 µg/100g) while vitamin E, B1 and B2 in trace concentration. Otherwise, the phytochemical analysis (mg/100g) based on dry weight revealed an appreciable amount of total phenol (2407.10±8.36), flavonoids (14.29±0.56), tannins (55.11±0.44), catechin (392.93±1.01) and also carotenoids (108.19±7.42 µg/100g). Organic acids profile (mg/100mL) showed citric acid (175.06±0.02) and salicylic acid (109.85±0.01) as major organic acids. Mineral composition (mg/100g) on dry weight basis revealed that potassium (1303.67±0.58) is the most abundant followed by phosphorus (303.33±5.77), calcium (187.33±0.58) and magnesium (141.33±0.57). Furthermore, the Phytates:Zn, Phytates:Ca, Oxalates:Ca and Phytates*Ca:Zn molar ratios recorded were all below than recommended threshold values, implying a bioavailability of zinc and calcium. These data indicate that the pulp of this fruit could be a good source of ingredient for both medicine and food industries in production.

This study aimed to investigate appropriate seed rates for legume-turnip intercrops under different harvest stages. Turnip (Brassica rapa L. var. rapa) was sown with common vetch (Vicia sativa L.), Hungarian vetch (Vicia pannonica Crantz) and pea (Pisum sativum ssp. arvense L. Poir) in 2014 with four different combinations (100% legume, 75% legume + 25% turnip, 50% legume + 50% turnip, 100% turnip) and catted in two different times when the beginning and end of the flowering of turnip. The study was conducted in Yozgat-Turkey with three replicates.

Within the research area, subsidy excluded income per unit area was found as 2447.24 USD/ha and subsidy included income was found as 3529.39 USD/ha. It was found that, agricultural subsidies increase the income per unit area at a level of 44.22%, and deficiency payments have the biggest share in this contribution (1052.97 USD/ha).

Genetically modified (GM) crops are being planted at large scale worldwide. In most of the countries, GM crops are processed into livestock feed. The land is used for cultivation of GM plants has been increased in recent years; in 2012 GM plants were grown on over 170 million hectares in 28 countries by 17.3 million farmers and extended to 185.1 million hectors in 2016 worldwide. GM plants have been used as feed for animals and the number of studies has proved their safety for animal and public health. This paper reviews the possible effects of GM crops on livestock, poultry, and aquatic animals by reviewing different type of studies, in which parameters such as performance, reproductive and health assessment were investigated. The most of peer-reviewed papers evaluating the effects of feeding animals with transgenic crops were based on GM plants with improved agronomic traits i.e. herbicide-tolerant plants and pets-tolerant plants; however, in some cases GM plants with boosted nutritional properties assessed. In most experiments, either Bt (Bacillus thuringiensis) maize, Roundup Ready (RR) soybean or both fed to animals. Measurable differences in various parameters were mostly observed in Bt maize and soybean fed separately or simultaneously to animals. In this review, scientific studies showing the effects of the use of GM products in the nutrition of domestic animals on performance, health and reproductive parameters are investigated.

Probiyotik gıdalar, sindirim sisteminin çalışmasına yardımcı olan canlı mikroorganizmaları içeren gıdalardır. Bu gıdaların tüketimi sağlığın korunmasına ve bağışıklık sisteminin güçlenmesine olumlu katkı sağlamaktadır. Yapılan bu çalışma, probiyotik ürünlerin tüketim durumu ile tüketicilerin probiyotik ürünler hakkındaki bilgi düzeyini saptamak amacıyla yapılmıştır. Araştırma sonucunda ankete katılan bireylerin %51,7’si bayanlardan, %48,3’ü erkeklerden oluşurken yaşları 18 ile 65 arasında tespit edilmiştir. Probiyotik ürünler hakkında bilgiye erkekler %31,4 oranında sahip iken bayanlar %61,1 oranında sahip olduğu tespit edilmiştir. Ayrıca öğrenim seviyelerinin ve ekonomik durumların artışına bağlı olarak probiyotik ürünler hakkında bilgi seviyesinin anlamlı derecede arttığı görülmüştür. Probiyotik ürünleri tüketenlerin oranı %26,0 iken tüketenlerden fayda gördüğünü düşünen bireyler %79,1 olarak belirlenmiştir. Ek olarak probiyotik ürünleri tüketenlerin %77,3’ü bu ürünlerin doğal olduğunu düşünmektedir. Sonuç olarak probiyotik ürünlerin sağlığımıza olumlu katkısı olmasına rağmen tüketimi ve hakkındaki bilgi yeterli seviyede değildir. Kişilerin öğrenim seviyesi ve ekonomik refahı yükseldikçe probiyotik ürün tüketimi ve bilgi düzeyi artmaktadır. Bu nedenle buna benzer toplumun bilgisini ölçmeye dönük çalışmaların periyodik olarak yapılması önerilmektedir.

The aims of this study were to evaluate the traits of reproductive, milking and growth performance of Saanen and Saanen × Hair crossbreds (F1, B1 and B2) raised at the Bandırma Sheep Research Institute. The data were collected from 868 goats for reproductive performance and milk yield and from 1077 kids for survival performance between 2009-2012. Milk components (fat, protein, lactose and non-fat dry matter) of goats (n=162) and body weight changes of kid’s (n=64) were evaluated for one year in 2012. Estrus rates and survival rates were similar among all genotypes. Kidding rate was significantly higher in F1 goats than Saanen goats. Saanen goat had the lowest average mean daily milk yield compared with other genotypes. The effect of year and age were significant on milk yield. Goats in F1 and B1 genotypes had higher milk protein percentage and non-fat dry matter content in comparison with Saanen and B2 genotype. Milk fat and lactose contents were similar among genotypes. Birth weight and monthly live weight were similar between genotypes while weaning weight, six month live weight and yearling live weight were higher in B1 kids in comparison with Saanen kids. The effect of dam age and birth type were significant on birth weight, monthly live weight and weaning weight. The findings related to performance characteristics in goat genotypes investigated show that B1 genotype could be recommend for semi-intensive production system in the Western Anatolia.
