Effects of vermicomposts obtained from rose oil processing wastes,dairy manure,municipal open market wastes and straw on plant growth,mineral nutrition,and nutrient uptake of corn

Study aims to investigate the effects of vermicomposts containing oil processing wastes, dairy manure, municipal open market wastes and straw on the growth, nutrient concentrations and nutrient uptakes of corn plant. For this, there different mixtures were prepared. Vermicomposts were applied with the rates of 0, 5000, 10000, and 20000 kg ha^?1 to 2 kg soil containing pots. Study was conducted in growth chamber for 2 months. Vermicompost applications increased plant growth, some plant nutrient concentrations and uptake. Also, vermicomposts showed the variation on parameters depending on their mixtures. Results showed that nutrients taken by the plant increased with the vermicompost until 10000 kg ha^?1 dose. Most of the nutrient concentrations such as phosphorus, potassium, calcium, magnesium, iron, and manganese (P, K, Ca, Mg, Fe, and Mn) were not increased in plant tissues, whereas uptake of them by the plant showed a significant increase. In addition, residual soil nutrients increased with the increase in vermicompost levels.     

Assessment of genetic relationships among 29 introduced and 49 local sweet cherry accessions in Turkey using AFLP and SSR markers

Summary

The characterisation of sweet cherry (Prunus avium L.) genetic resources in Turkey may help to increase their use in breeding programmes worldwide, as Turkey is the centre of origin of sweet cherry. Amplified fragment length polymorphism (AFLP) and simple sequence repeat (SSR) markers were therefore used to analyse genetic diversity among a total of 78 local and introduced sweet cherry cultivars. Four AFLP primer combinations, and six SSR primer pairs for sweet cherry were used for genetic diversity analysis. A genetic similarity matrix was calculated using the combined data from AFLP and SSR analyses with simple matching coefficient. Genetic similarities among the sweet cherry genotypes studied were higher than 42%. No two accessions had an identical AFLP and SSR marker profile, indicating that all 78 genotypes were unique. An UPGMA dendrogram, based on the similarity matrix, revealed 18 separate Groups at or above the 70% similarity level. While some Groups consisted of both introduced and local genotypes, other Groups had only local genotypes. This result suggests that there was broad genetic diversity among the local Turkish sweet cherry genotypes, which was not present in the introduced sweet cherry accessions. The genetic variation present in local Turkish sweet cherry genotypes may be useful for future breeding programmes. We found that the use of both SSR and AFLP marker systems was effective for distinguishing between genetically-close sweet cherry genotypes. These marker systems can be used to complement pomological and morphological markers during the characterisation and identification of sweet cherry genotypes.     

Determination of Energy Use Efficiency and Greenhouse Gas (GHG) Emissions of Pistachio (Pistacia vera L.) Production in Adıyaman Province

The purpose of this research is to perform the energy use efficiency and greenhouse gas (GHG) emissions of pistachio production. This research was performed for 2016 and 2017 production season in Ad?yaman province of Turkey in dry conditions in 2017. The data supplied from research were collected from 152 different farms by face to face surveys with simple random sampling method. The agricultural input energies and output energies used in pistachio production were computed to determine the energy use efficiency. According to the research findings, the energy inputs in pistachio production were computed respectively as 4561.11?MJ ha^?1 (35.50%) diesel fuel energy, 3206.24?MJ ha^?1 (24.96%) chemical fertilizers energy, 2420.93?MJ ha^?1 (18.84%) machinery energy, 1020.06?MJ ha^?1 (7.94%) human labour energy, 715.69?MJ ha^?1 (5.57%) animal labour energy, 656.95?MJ ha^?1 (5.11%) farmyard manure energy and 266.16?MJ ha^?1 (2.07%) chemicals energy. Total input energy was computed as 12,847.14?MJ ha^?1. Energy values of pistachio yield were computed as 15,008.65?MJ ha^?1. Energy use efficiency, specific energy, energy productivity and net energy computations were computed respectively as 1.17, 22.32?MJ kg^?1, 0.04?kg MJ^?1 and 2161.51?MJ ha^?1. The consumed total energy input in pistachio production can be classified as 49.01% direct, 50.99% indirect, 18.62% renewable and 81.38% non-renewable. Total GHG emission was computed as 1123.72?kg CO_2?eqha^?1 for pistachio production with the greatest portions for human labour (32.42%). The human labour followed up chemical fertilizers usage (23.21%), diesel fuel consumption (19.89%), machinery usage (15.30%), farmyard manure usage (5.65%), chemicals usage (3.25%) and animal labour usage (0.27%), respectively. Additionally, GHG ratio value was computed as 1.95 kgCO_2?eqkg^?1 in pistachio production.

     

Fusarium oxysporum f. sp. lycopersici races and their genetic discrimination by molecular markers in West Mediterranean region of Turkey

Fusarium oxysporum f. sp. lycopersici (FOL) races and F. oxysporum f. sp. radicis lycopersici (FORL), the causal agents of root rot and crown rot diseases, respectively, cause serious economic losses in tomato greenhouses where production is intensive in the West Mediterranean region of Turkey. The isolates were collected from West Mediterranean region of Turkey and were characterized by specific primers based on three races (r1, r2, r3), besides pathogenicity tests in in vivo conditions Additionally, a scheme was developed using newly tested ISSR and SRAP markers to a genotyping database and to determine the possible origin of these pathogens. The present study provided new information on these pathogens based on their races and their dominant existence in this region that has not been reported before. Genetic diversity detected in the same races of the pathogen may be associated with difficulties in controlling the pathogen and a possible resistance formation effort exerted by the pathogen to chemicals used in plant protection in tomato greenhouses. Molecular analyses indicated genetic diversity in pathogen isolates identified as r3, r2 and FORL, which may be associated with abiotic stress to which the pathogens were exposed.     

Design of Neural Network Predictor for the Physical Properties of Almond Nuts

In this study, an adaptive neuro fuzzy interface system (ANFIS) based predictor was designed to predict the physical properties of four almond types. Measurements of the dimensions, length, width and thickness were carried out for one hundred randomly selected samples of each type. With using these three major perpendicular dimensions, some physical parameters such as projected area, arithmetic mean diameter, geometric mean diameter, sphericity, surface area, volume, shape index and aspect ratio were estimated. In in a various Artificial Neural Network (ANN) structures, ANFIS structure which has given the best results was selected. The parameters analytically estimated and those predicted were given in the form of figures. The root mean-squared error (RMSE) was found to be 0.0001 which is quite low. ANFIS approach has given a superior outcome in the prediction of the Physical Properties of Almond Nuts.     

Pharmacokinetics and bioavailability of danofloxacin in chukar partridge (Alectoris chukar) following intravenous,intramuscular, subcutaneous,and oral administrations

The aim of the present study was to determine the pharmacokinetics (PKs) and bioavailability of danofloxacin in chukar partridge (Alectoris chukar) following intravenous (IV), intramuscular (IM), subcutaneous (SC), and oral (PO) administrations at a dose of 10 mg/kg. A total of eight clinically healthy chukar partridges weighing 480 ± 45 g were used for the investigation. The study was performed in a crossover design (2 × 2 × 2 × 2) with a 15‐day washout period between two administrations in four periods. The plasma concentrations of danofloxacin were determined using reversed‐phase high‐performance liquid chromatography. Noncompartmental PK parameters were also estimated. No local or systemic adverse drug effects were observed in any of the chukar partridges. The mean elimination half‐life ranged between 8.18 and 12.08 hr and differed statistically among administration routes. The mean peak plasma concentrations of danofloxacin following IM, SC, and PO administrations were 8.05, 9.58, and 3.39 μg/ml at 0.5, 1, and 4 hr, respectively. Following IM, SC, and PO administrations, the mean bioavailability was 86.33%, 134.40%, and 47.62%, respectively. The mean total clearance and volume of distribution at steady‐state following IV administration were 0.13 L hr^?1 kg^?1 and 0.96 L/kg, respectively. These data, including favorable PKs and the absence of adverse drug effects, suggest that danofloxacin is a useful antibiotic in chukar partridges.     

Gene effects of Cicer reticulatum on qualitative and quantitative traits in the cultivated chickpea

The gene effects of Cicer reticulatum on both double‐podding as qualitative traits and yield criteria as quantitative traits in interspecific hybridization with cultivated chickpea (Cicer arietinum) have not yet been elucidated, despite the easy acquisition of hybrid progeny between two species. This study sought to answer three questions concerning qualitative and quantitative traits in reciprocal crosses between C. arietinum and C. reticulatum. (i) Is there a similarity in the gene effects of flower colour, pigmentation and double‐podded traits in reciprocal interspecific crosses? (ii) What are the expressivity and penetrance of the double‐podded trait in interspecific crosses? (iii) Which heterosis predicts the occurrence and the extent of transgressive variation? The materials for this study were F₁, F₂ and F₃ progeny derived from a reciprocal cross between C. arietinum and C. reticulatum. As qualitative traits, purple flower colour, pigmentation and single‐podded traits in C. reticulatum were governed by a dominant single gene. Purple flower colour and pigmentation were detected to be linked traits as all progeny had the same phenotypes. As quantitative traits, yield criteria in progeny which were double‐podded had higher values than the single‐podded counterparts. Expressivity and penetrance of the double‐podding trait were superior in progeny derived from C. reticulatum × C. arietinum. The results showed that fruitful heterosis was more useful than residual heterosis in F₃ as residual heterosis was mostly negative and fruitful heterosis was suggested in self‐pollinated species such as chickpea that lacks inbreeding depression. Interspecific transgression was significant with respect to chickpea improvement because it represented a potential source of novel genetic variation.     

Distribution and genetic diversity of Dothistroma septosporum in Pinus brutia forests of south-western Turkey

Dothistroma needle blight (DNB) is a serious disease of the Pinaceae, mainly Pinus species, caused by the fungi Dothistroma septosporum and D. pini. Both species are regarded as invasive forest pathogens worldwide, with rising incidence in central and northern Europe over the last three decades. In this work, 29 sites were investigated between 2013 and 2015 in south-western Turkey. Morphological examination of needles confirmed DNB infection (i.e., Dothistroma conidiospores observed) at 18 sites, and a total of 108 Dothistroma sp. isolates were obtained from 11 of the sites. Host age seemed to be an important factor in both occurrence and severity of DNB in Pinus brutia forests. Continuous rainy days, especially in December, may increase severity of disease; however, extreme rain events may reduce available conidiospores on plant tissues or in the air. Species-specific mating type primers showed that all isolates were D. septosporum; D. pini was not detected. The mating type ratio was close to 1:1, indicating sexual recombination was occurring. Eleven microsatellite markers revealed 59 unique multilocus haplotypes (MLHs) among the 73 isolates originating from different conidiomata. The majority of MLHs were represented by a single isolate (n = 52) and only one MLH was shared between two localities. Analyses showed high genetic diversity, isolation-by-distance, and clear population clusters. These findings suggest that D. septosporum is well established in south-western Turkey and is probably not a recent introduction.     

Prevalence and economic significance of bovine hypodermosis in Afyonkarahisar province of Turkey

This study was carried out to investigate the prevalence and economic losses due to in cattle of hypodermosis between May 2008 and April 2009 in Afyonkarahisar province of Turkey. A total of 6,598 cattle—3,498 in pasture and 3,100 in slaughterhouse—were examined for hypodermosis. One hundred ninety-five out of 6,598 cattle (2.96%) were found positive. Concerning this infestation rate, the prevalence of hypodermosis in field was 5.3%, whereas the prevalence was 0.3% in slaughter house. Hypoderma bovis and Hypoderma lineatum were recorded in slaughter house. First-stage Hypoderma spp. larvae weren’t found in cattle organs in slaughterhouse. The annual economic loss on skins is estimated to be about 18,288 TL (currency exchange rate is 1 USD:1.499 TL).     

Transgressive segregations for yield criteria in reciprocal interspecific crosses between <Emphasis Type="Italic">Cicer arietinum</Emphasis> L. and <Emphasis Type="Italic">C. reticulatum</Emphasis> Ladiz.

Wild Cicer species are considered to be more resistant for biotic and abiotic stresses than that of the cultivated chickpea (Cicer arietinum L.). Alien genes conferring resistance for biotic and abiotic stresses can be transferred from wild Cicer species to the cultivated chickpea but success in interspecific hybridizations has already been achieved with only two wild Cicer species. The current study was undertaken to compare fruitful heterosis in F₂ and F₃ for yield and yield criteria and to identify transgressive segregation in F₂ and F₃ in reciprocal interspecific crosses between C. arietinum and C. reticulatum Ladiz. We define fruitful heterosis as a useful parameter that can be used instead of residual heterosis. Considerable fruitful heterosis in F₂ and F₃ was found for number of seeds, pods per plant, biological yield, and seed yield. Maximum values of most of the characteristics in F₂ and F₃ were higher than that of the best parent indicating that superior progeny could be selected for yield from transgressive segregation. Progeny selection should be based on number of seeds, pods per plant, and biological yield since these characteristics had the highest direct effect on seed yield. The narrow sense heritability was found to be the highest for 100-seed weight. It was suggested that the cultivated chickpea could be used as female parent in interspecific hybridization to increase yield and yield criteria since progeny in F₂ and F₃ had better performance when it was used as female. In conclusion, interspecific hybridization of wild and cultivated chickpea can be used to improve yield and yield components and resistance to biotic and abiotic stresses as well.
