The amount and area of the leaves should be at an optimum level in order to maintain the product quality and not to adversely affect the vine growth. Because carbohydrates, which are essential for omca and are mostly stored in fruit and wood, are formed by leaves after photosynthesis. Leaf area can be used in many areas. Among these, photosynthesis capacity and plant growth rate may. Various tools and methods (planimetry, leaf area meter, width-product, weight-area calculation, image processing programs, etc.) are used in determining leaf area. In this study, 3 American grape rootstocks (5BB, 110 R, 1103 P) and 5 grapes (Alphonse Lavallée, Italıa, Mıchele Palierı and Narince, Yalova İncisi) were used as material. 20 shoots with 15-25 nodules were taken from the rootstocks and varieties of the omca and the leaves were photocopied according to the order of the node. The actual field values of the leaves were measured with a planimeter. Leaf stem and leaf width and length of the leaves were also measured. Regression analysis was performed between leaf stem, leaf blade width and length, leaf blade × length values and real area. The maximum leaf area on one shoot was 5 BB (2484 cm2) from rootstocks and Narince (2126 cm2) from varieties. All three rootstocks gave the average value of the leaf found in 9th node. In terms of node number, which gives an average value according to the varieties, Alphonse Lavallée, Mıchele Palierı and Yalova İncisi varieties came to the forefront in 11th node. The 13th in Narince cultivar and the 12th in Italia cultivar gave the closest value to the average.

Apiculture is one of the agricultural activities carried out widely in our country and in the world. Our society attaches great importance to beekeeping and honey products, especially honey, so bee colony health is very important in the continuity of bee products. There are many factors that can be shown to cause colony loss in bees and one of them is poisoning caused by pesticides. Causes such as improper dosing of pesticides, day-to-day spraying, or potentiation or effect differentiation due to random mixing of drugs may cause collective bee deaths. In this study, 188 dead bee samples (each sample contains approximately 100 g dead bees) from different bee farms, which were collected from beekeepers and brought to Adana Veterinary Control Institute with the suspicion of pesticide poisoning due to intensive deaths, were examined. Qualitative examination was performed by gas chromatography (GC) device. In the examination of dead bee samples, tau-fluvalinate residue was found in 2 samples in 2015 and cypermethrin residue was found in 1 sample in 2016. In 2017 and 2018, no detectable substance was detected in terms of pyrethroid pesticides. In 188 samples which we examined in terms of pyrethroit group pesticides, 1 substance was found to be toxic for bees. This shows, at the samples examined, that pyrethroid pesticides are not involved in bee colony losses in Çukurova.

This experiment was conducted in Antsokia Gemza district, Ethiopia in 2017/18 to evaluate the effect of intra-row spacing on bulb quality and storability of onion varieties. A 4×4 factorial experiment with four different varieties (Adama Red, Bombay Red, Melkam and Shendi) and four levels of intra-row spacing (5.00, 7.50, 10.00 and 12.50 cm) was laid on randomized complete block design with three replications. Data were collected on bulb quality attributes and storability and subjected to Analysis of Variance (ANOVA) using statistical analysis system (SAS) computer software 9.1. The mean separation test was done by list significant difference (LSD) test at 5% probability level. Simple linear correlation analyses between and among the different parameters were made using Pearson Correlation Coefficient. Accordingly, most of the parameters were significantly affected by intra-row spacing and variety. Variety Melkam exhibited the highest bulb diameter, bulb length, bulb dry matter content and bulb fresh weight. Melkam and Adama Red were with the lowest weight loss in storage while Bombay Red and Shendi scored the highest weight loss in storage. Most of the bulb quality parameters were significantly highest at the widest intra-row spacing of 10.00 and 12.50 cm. However, there was no significant variation between 7.50 and 10.00 cm intra-row spacing on average bulb weight which is considered as the most important bulb quality parameter for the producers from the market point of view. Weight loss was higher at the widest intra-row spacing for all varieties. Based on the findings of this study, it can be concluded that the bulb quality and storability of onion in Antsokia Gemza district can be optimized through cultivating variety Melkam at intra-row spacing of 7.5 cm.

Powdery mildew is a serious disease of economically important hazelnut crop in Turkey. Hazelnut production has been extremely affected by the disease in terms of quality and quantity. The disease is caused by two different fungi, namely Erysiphe corylacearum and Phyllactinia guttata. E. corylacearum has been shown to be the responsible one predominantly for the recent economic damage. The fungi produce a mycelium network on hazelnut plants before they sporulate and visually detected. Early detection of these pathogens is important for management as well as understanding their spread and epidemics. In this study, a PCR assay was developed for the detection of both pathogens from hazelnut plant leaves by targeting their ribosomal DNA genes in their internal transcribed spacer (ITS) regions. Two sets of specific primers were designed for the detection of E. corylacearum and P. guttata at an early stage of infection. As a result of PCR, a specific band of 578 bp was observed. The amplicon sequencing confirmed the presence of only E. corylacearum, but not P. guttata. Therefore, this PCR-based test can identify plants that are infected with powdery mildew before they show any visual signs. From there, the infected plants can be treated or removed before the fungus has a chance to produce spores that infect neighboring plants. These results would help tackle the eradication of powdery mildew.

This study was carried out to investigate the changes in semen characteristics, hormonal profile and testicular morphometry of West African Dwarf (WAD) goat bucks treated with danazol. For this purpose, eighteen matured WAD bucks average of about two years were randomly divided into groups A, B and C comprising of six bucks per group. Group A was the control while B and C bucks were given danazol at a dose rate of 20mg/kg body weight orally daily for four weeks. The group B bucks’ testes were harvested thereafter for gross and histo-morphometric studies while those of group C were left intact but danazol treatment was withdrawn for four more weeks. The bucks’ semen samples (collected by electro-ejaculation) and hormonal samples (taken via the jugular vein) were analyzed. The semen characteristics studied included color, volume, mass activity, motility, percentage normal live-dead ratio, morphology and concentration; while the hormones studied included testosterone, follicle stimulating hormone and luteinizing hormone. Results show that there were significant decreases in semen characteristics of group B and C bucks compared with those of group A in the first four weeks. The semen characteristics of the group C bucks were reversed to normal range (similar to those of group A bucks) two weeks after danazol treatment was withdrawn. Similar results were observed with the hormonal studies. In conclusion, danazol caused a reversed reduction in sperm cells characteristics suggesting its possible use as a contraceptive in WAD goat bucks.

Access to land in Bangladesh is governed by the state rule but informal tenure arrangement is existing all over the country. Land productivity differs with the contractual arrangement between landlord and tenant. Inefficiency may arise due to sharecropping which is known as Marshallian inefficiency. This study investigated the productivity the productivity, profitability and efficiency of different tenure arrangement of Boro rice cultivation selecting 120 farmers from Rangpur district of Bangladesh. The stochastic frontier production function was employed to determine the efficiency. Moreover, t-test was performed to see whether any significant difference exist among tenure categories in terms of productivity, profitability and efficiency. Four types of tenure arrangements were identified as cash tenant, fifty-fifty input-output sharing arrangement, only output sharing arrangement and owner farmers. Result revealed that productivity and profitability was higher for owner and cash tenant compared to others. Significant productivity and profitability difference were found between owner farmers and cash tenants versus sharecroppers. Result also found that inefficiency level was significantly high for fifty-fifty input-output share tenant and only output share tenant compared to cash tenant and owner operator implying that Marshallian inefficiency exist due to sharecropping system in the Boro rice production.

The study was conducted to determine forage quality criteria of Salvia multicaulis VAHL. species collected from different locations of Southeastern Anatolia Region of Turkey in 2018. Results of statistical analysis of the study data revealed that there were significant differences among the locations for all of the investigated traits. Additionally, among the locations the investigated traits were changed as following; dry matter content (DM) 88.66-91.58%, crude protein content (CP) 16.47-25.37%, insoluble protein content in acid detergent (ADP) 0.8%-1.10%, acid detergent fiber content (ADF) 22.08-29.54%, neutral detergent fiber content (NDF) 29.71-%43.85%, calcium (Ca) content 1.22-1.82%, phosphor (P) content 0.23-0,40%, Ca:P ratio 3.05-6.87, potassium (K) content 1.20-2.58%, magnesium (Mg) content 0.28-0.46% and K/(Ca+Mg) ratio 0.55-1.44. Results of the study revealed that dry forage of Salvia multicaulis species is both rich in terms of crude protein content and having a high digestibility level and its macro minerals content and K/(Ca+Mg) ratio to be sufficient for animal feeding. However, due to its too high level Ca:P ratio than critical top level (2:1), it is important to be careful against the risk of poisoning of animals when the forages of this species are used in animal feeding. Hence, additional research is required to determine the harmful effect of the species on the livestock health.

Lumbar disc herniation (LDH) is a common cause of low back pain and radicular pain. The aim of our study was to evaluate the regression of LDH in patients who are considered to require surgical treatment but prefer conservative treatment. Patients who presented between January 2018 and June 2020 and who did not accept the recommended surgical treatment following a diagnosis of LDH based on clinical and radiological findings were retrospectively reviewed. All 12 of the patients included in the study showed spontaneous regression of LDH during outpatient clinical follow-up. Our study included 12 patients (seven male and five female). The mean age was 46.5 (the youngest was 30 years old; the oldest was 70 years old). Regression was observed at the L2-L3 level in two patients (10%), at the L4-L5 level in four patients (40%), and at the L5-S1 level in six patients (50%). On the follow-up examination of all patients, the severity of their pain was evaluated with the Visual Analogue Scale, and all patients described a reduction in pain (min: 2, max: 8). Ten patients described radicular pain at the initial examination, eight patients received physical therapy and rehabilitation treatment before the follow-up examination, and nine patients described neuropathic pain at the follow-up examination. Spontaneous regression of LDH is rare. While conservative treatments provided partial improvement in the complaints of these patients, conservative treatments usually cannot prevent the development of neuropathic pain.

Heavy metal environmental contamination consequent of anthropogenic factors has become a global concern with cadmium and lead constituting a major public health, livestock and ecological threat. This study, therefore, uses goats (as sentinel animals) raised in 2 different regions based on their mining history (previous and existing) to evaluate exposure to cadmium and lead and their consequent toxicities and pathological changes. A total of 130 goats (composed of 88 goats which constitute the suspected exposure (SE) group and 44 goats, the suspected unexposed (SU) group) were sampled. Blood and tissue samples (liver, kidney and muscles) were analysed for lead and cadmium levels using Atomic Absorption Spectrophotometer along with the complete blood count analysis. The mean blood lead levels (BLLs) and cadmium levels (BCLs) in the goats from the SE groups were 14.59 and 3.12 µg/dl respectively, which were significantly higher than the SU groups (9.23 and 0.46 µg/dl respectively) A significantly higher frequency of goats in the SE (93.18%) also had an elevated BLLs compared to the SU group (78.57%). The levels of tissue lead and cadmium in both the SE and SU groups were found significant and higher than the FAO/WHO maximum limits. The packed cell volume, red blood cell count, and haemoglobin concentration were found significantly lower, and the platelet count and some leucocyte parameters (total white blood cell, neutrophil, eosinophil, and monocyte count) were found significantly higher in the SE group. The elevated cadmium and lead level in both groups further highlight the ubiquitous spread of cadmium and lead environmental contamination in both study regions and the direct risk of exposure to human and animals in Nigeria. The relative differences in the observed pathological changes in the two study groups also suggest the influence of the environmental heavy metal pollution and exposure levels on health.
