Published: April 2017

The commercial production of cultivated-mushroom, which has a forty years of past in Turkey, was started after 1980s. Until the recent decade, most of the total amount of production in Turkey was performed by family members while the cultivation of the product has gained an upward trend since the beginning of 2000s, though the amount and development rate were not enough. During that time, a number of large (>2000 m2) and medium (500-2000 m2) scale mushroom production facilities were established and Turkey has gained an important place in mushroom production in the world. In this study, we aimed to reveal the common production methods of ten medium and large scale mushroom companies whose daily production capacities are above 1 ton in six regions. In this respect, all companies have been visited and communicated directly with company representatives and a survey comprising 65 questions about company, production facility, compost and casing soil, production systems, diseases and pests and packaging was made. The findings have suggested us that such companies have mostly a history of 15 years of time and have a land size of 10-50 thousand m2, while their mushroom production areas vary between in size and that they make use of technology in production and automation in their plants and they have quality management systems (ITU, ISO 9001, ISO 22000 and Global Gap ) and they employ generally qualified and experienced technicians or agriculture engineers and also that 40% of them receive consultancy and also that they use their own productions or standard ready mycelium planted compost and that they use domestic peat as casing material and that they package the mushrooms with their brands and sell to markets mostly and lastly that they conduct pre-sale quality sorting and grading. It was also seen that there is lack of food engineers employed and most of the companies do not receive consultancy, and that the waste compost is not evaluated correctly and that the covering material is not in the required standards and that there are even companies not doing any water analysis and that coal for heating and chemicals for disinfection are used and that diseases and pests are inevitable and last that they lack in processing different products.

Increasing of industrialization and population has resulted in the accumulation of a wide variety of chemicals. Especially, widespread use of synthetic and toxic chemicals have led to an effort to improve new technologies to reduce or eliminate these contaminants from the environment. Chemical methods that used for the treatment of toxic materials are expensive, time-consuming and difficult, especially in extensive agricultural areas. Furthermore these methods led to formation of new chemical pollutants. Recent years, one promising alternative treatment method is to use of microorganisms for the biodegradation of these toxic chemicals. This method is effective, minimally hazardous, economical, versatile and environment friendly. In this study, we thought that microflora of insecticide resistant insects may be a potential reservoir for the isolation of new bacteria that can be used for the biodegradation of insecticides. In this research work, totally 24 bacterial isolates capable of biodegradation α-endosulsan were isolated from the body microflora of insects belong to Orthoptera, Dermaptera, Mantodea and Hymenoptera orders. Based on the some morphological, physiological and biochemical characteristics and fatty acid profiles they were identified as Stenotrophomonas, Pseudomonas, Acinetobacter, Bacillus, Brevibacillus, Flavimonas and Rhodococcus. As a result, these isolates can be used for the treatment of α-endosulfan residues at different environments.

Antioxidants are naturally occurring substances that combat oxidative damage in biological entities. An antioxidant achieves this by slowing or preventing the oxidation process that can damage cells in the body. It does this by getting oxidized itself in place of the cells. The aim of the present study was to evaluate the in vitro antioxidant and free radical scavenging activities of aqueous and 95% methanol leaf extracts of four herbs viz. Trigonella foenum-graecum L, Murraya koenigii, Coriandrum sativum and Centella asiatica which have frequent use in Indian cuisine. Both aqueous and 95% methanol leaf extracts have shown significant amount reducing power. Both aqueous and 95% methanol leaf extracts of Coriandrum sativum had significant DPPH radical scavenging activity with IC50 value of 0.21± 0.3 mg/L and 0.176 ± 0.008 mg/L respectively. The aqueous leaf extract of Trigonella foenum-graecum L showed low scavenging activity. Among all the leaf extracts, the aqueous leaf extract of Centella asiatica has exhibited significantly high NO radical scavenging activity (80%) with IC50 value of 0.11 ± 0.17 mg/L. The aqueous leaf extracts of the samples have showed significantly high superoxide radical scavenging activity. The activity was maximum for the aqueous leaf extract of Centella asiatica, IC50 value is 4.36 ± 0.41 mg/L. anti lipid peroxide activities were very high ( 90 %) for aqueous leaf extracts of Coriandrum sativum (IC50 = 0.064 ± 0.85 mg/L) and Centella asiatica (IC50 = 0.066 ± 0.9mg/L) at a concentration of 0.16 mg/L. The aqueous leaf extracts of the samples were found to contain large amounts of flavonoids and phenolic compounds and exhibited high antioxidant and free radical scavenging activities. These in vitro assays indicate that these plant extracts are significant source of natural antioxidants which might be helpful in preventing the progress of various oxidative stresses.

WRKY transcription factors are a class of DNA-binding proteins that bind with a specific sequence C/TTGACT/C known as W-Box found in promoters of genes which are regulated by these WRKYs. From previous studies, 43 different stress responsive WRKY transcription factors in Arabidopsis thaliana, identified and then categorized in three groups viz., abiotic, biotic and both of these stresses. A comprehensive genome wide analysis including chromosomal localization, gene structure analysis, multiple sequence alignment, phylogenetic analysis and promoter analysis of these WRKY genes was carried out in this study to determine the functional homology in Arabidopsis. This analysis led to the classification of these WRKY family members into 3 major groups and subgroups and showed evolutionary relationship among these groups on the base of their functional WRKY domain, chromosomal localization and intron/exon structure. The proposed groups of these stress responsive WRKY genes and annotation based on their position on chromosomes can also be explored to determine their functional homology in other plant species in relation to different stresses. The result of the present study provides indispensable genomic information for the stress responsive WRKY transcription factors in Arabidopsis and will pave the way to explain the precise role of various AtWRKYs in plant growth and development under stressed conditions.

Published: April 2017

Like the whole sub-Sahara Africa, rainfall in Fina reserve is subject of strong inter-annual variability. This paper assesses farmers’ perception on land use utilised in the Fina biosphere reserve and their adaptation measures to climate variability. The statistical methods (descriptive and inferential analysis) are used in this study to determine farmers’ perceptions and the adaptation measures in the Fina reserve. Results reveal that 75.5% of the farmers noticed an increase in temperature and decrease in rainfall ignoring the recent recovery observed in the annual rainfall. The length of rainy season is considered to be shorter according to 77.6% of farmers involved to the investigation. However, all the farmers underlined frequent and longer dry spell. Bush fire is considered by 10.2% of farmers as the major factor affecting the natural resources of the reserve and only about 10% of farmers accorded much importance to agricultural land as contributor to reserve degradation. Most of the farmers are limited by lack of manpower and not by the reserve rule to increase their farmlands. The major adaptation measures are the methods of shifting cultivation and improving seed which are practiced by 51% and 87.8% of farmers, respectively. New adaptation strategies such as adoption of planting pits and stone-bunds for water retention need to be practiced by farmers.

The aim of this study was to evaluate the effects of a natural antioxidant derived from rosemary extract on the stabilization of palmolein oil during deep-fat frying of Noodles. Palmolein oil with tertiary butylhydroquinone (TBHQ), a synthetic antioxidant and palmolein without antioxidant were used as positive controls. Thermo-oxidative transformation were measured according to various physical and chemical parameters. Total polar compounds (TPC), free fatty acids (FFA) were measured during the study. All the parameters evaluated in the study increased with the number of frying cycles. The order of effectiveness of antioxidants for inhibition of palmolein oil degradation in deep-noodles was: PRESOL (rosemary based extract) > TBHQ > Control. In terms of oil consumption, it was observed that noodles fried in oil with rosemary extract had lower value of oil consumption as compared to TBHQ and control. The TBHQ degradation kinetics was also evaluated with frying cycle. It showed an exponential decay with increase in frying cycles. Also samples containing natural antioxidant had a least changes in the colour as compared to TBHQ and control at the end of frying cycle.

Published: April 2017

Charcoal rot is a soil and seed borne, economically important fungal disease on dry bean in Turkey. Twenty bean isolates of M. phaseolina collected from different locations in Turkey during 2008 and 2012 years were studied for genetic variability using random amplified polymorphic DNA (RAPD) assay, chlorate sensitivity on medium supplemented with 120mM of potassium, phenotype of colony, and pathogenicity. Isolates were identified as M. phaseolina based on morhological features and PCR assays using species-specific primers (MPKF1and MPKR1). Isolates of M. phaseolina were analysed for their aggressiveness on the susceptible bean cv. Akman 98, by soil inoculation method. Isolates exhibiting a dense chlorate phenotype were chlorate-resistant, while those possessing feathery and restricted chlorate phenotypes were chlorate-sensitive. More than half of the isolates (55%) were resistant to chlorate and produced dense phenotype, while 35% isolates showed feathery and two isolates (10%) showed restricted growth. DNA from 20 isolates was subjected to genetic diversity analysis by the RAPD method using 14 randomly chosen 10-base random primers, and low genetic diversity (33.3%) was observed among the tested isolates.

In this study, the objective was to determine the factors affecting farmers’ decisions on organic livestock. Within this scope, the Gümüşhane province, in which one of the major organic livestock projects has been carried out, was taken into the focus of attention for this study. The data of the study was obtained from 134 surveys based on census and focusing on farmers doing conventional animal breeding and possessing 25 or more cattle. The data obtained were used in predicting the Logit Model. In the model, it was determined that the inclination to transition to organic animal breeding in institutions where the rate of benefiting from animal breeding supports and the rate of meeting forage requirements from their own are high and besides where the rate of using industrial feed is low. As a result, it was recommended that the government support for forage crops, which are already within the current support policies, should be increased on yearly basis. This will have a positive effect on the decision of the farmers to choose organic livestock. This support is also important in terms of carrying out livestock activities in more profitable and technical way.

Published: April 2017

This study investigates the antioxidant components (total carotenoids, lycopene, β-carotene, total phenols, flavonoids, ascorbic acid and total vitamin C) as well as the hydrophilic and lipophilic antioxidant activities (HAA and LAA) of tomato genotypes consisting of one ordinary cultivar Rio Grande and the two high-lycopene breeding lines HLT-F71 and HLT-F72. The correlation of nutritional value to L∗, a∗, b∗ colour indexes and a∗/b∗ ratio was also investigated in whole and fresh cut tomato fruits. Except for β-carotene content, significant differences were found among cultivars for antioxidants. The berries of both HLT-lines recorded higher antioxidant contents, HAA and LAA (TEAC and FRAP assays) than Rio Grande. Under controlled conditions, HLT-F72 reached the highest levels of total carotenoids (165.5 mg β-ca Eq per kg fw), lycopene (150.1 mg per kg fw) and total phenolics (549.7 mg GAE per kg fw). However, HLT-F72 exhibited the highest levels of ascorbic acid (193.3 mg per kg fw), total vitamin C (271.6 mg per kg fw) and flavonoids (450.5 mg RE per kg fw). Line HLT-F71 showed the highest HAA (148.0 µM Trolox per 100 g fw and 4.2 mM FRAP per g fw) and LAA values (258.5 µM Trolox per 100 g fw and 3.2 mM FRAP per g fw respectively). Colour readings in red ripe fresh cut tomato berries particularly a∗, b∗ and the ratio a∗/b∗ could represent an indicator not only for lycopene but also for other phytochemicals and resulting antioxidant activities. HLT-Lines may serve as a starting point for the development of semi-determinate growth habit tomato cultivars with higher functional quality.

Published: April 2017

Ultrasonic measurements of Musculus longissmus dorsi thoracis et lumborum (MLD) were taken of Dorper (n=99) and Dorper x Merino (n=65) lambs at 156 days of age and comparisons made to various body dimensions to ascertain whether sex, genotype, birth type and live weight had any effect on these parameters. Lambs were weaned two months after birth and placed ad libitum on basic dry land pasture during the draught spring and summer months of 2014 in the arid southeastern region of Turkey. Least square means of backfat thickness, skin+backfat thickness, muscle depth, body length, chest girth and live weight, at the mean age of 156 days, were 0.17 cm, 0.32 cm, 1.75 cm, 63.30 cm, 72.37 cm and 25.16 kg, respectively. Genotype was a statistically significant factor in terms of back fat thickness (BFT), skin and backfat thickness (S+BFT), muscle depth (MD), body length (BL) and live weight (LW). The study showed that Dorper and Dorper x Merino genotypes into Turkey show a clear advantage over the native breeds in terms of meat production and quality not to mention the high potential for lean carcass production. Ultrasonic measurements of Longissimus thoracis et lumborum (MLD) will provide an important contribution to selection index in breeding programs for Dorper and Dorper crossbred genotypes. However estimation of genetic parameters are required in containing a pedigree database in order to establish an effective selection index.

Published: April 2017

This experiment was carried out to investigate the effects of variant doses of rosemary (Rosmarinus officinalis L.) essential oils (REO), vitamin E (α‐tocopheryl acetate) and antibiotic (chlortetracyclin) on the concentration of vitamin E, fatty acid composition, cholesterol levels in the yolk. In this experiment, 32 weeks old Bovans genotype and 240 white laying hens were randomly separated to six treatment groups with five replicas. While the control group was fed with basal diet the treatment groups were supplemented with 500 mg/kg antibiotics; 200 mg/kg vitamin E; 100, 200, and 300 mg/kg REO to basal diet for 90 consecutive days. The results showed that addition of antibiotics, vitamin E and REO to the diet had no effects on egg cholesterol, while fatty acid composition and vitamin E contents of the yolk were significantly affected. Addition of 100 mg/kg REO to the diet increased total mono unsaturated fatty acids (MUFA) by increasing oleic acid level but decreased Polyunsaturated fatty acids (PUFA) by decreasing linoleic acid content of the yolk. Addition of 200 mg/kg vitamin E to the diet significantly increased vitamin E content of egg. The study showed that the changes in yolk fatty acid composition and vitamin E content due to the feed additives, could affect positively in chemical composition of eggs. In conclusion, 100 mg/kg REO and 200 mg/kg vitamin E supplementation to the diet might cause high antioxidant capacity and could help to produce eggs that were more resistant to lipid oxidation.

Nigeria is one of the countries in sub-Saharan Africa with insufficient food and high food import bill, which have debilitating effects on the productive capacity of the citizens. Maize is the most important cereal after rice and its production contributes immensely to food availability on the tables of many Nigerians. This study examined the contribution of maize production to household food security status of rural maize-farming households in the southern guinea savannah of Oyo state, Nigeria. A multistage sampling procedure was used to select 200 farm households and the data were analysed using descriptive statistics, recommended daily calorie requirement (RDCR) approach, Logit model. Results showed that about three-quarters of the households were food secure and were able to meet the recommended calorie intake of 2260Kcal per capita per day. The shortfall index (P) which measures the extent of deviation from the food security line, indicated that the food secure households exceeded the RDCR by 65%, while the food insecure households fell short of the RDCR by 31%. The logit model showed that maize output, gender, primary occupation of the farmer, farm size and farming experience had a positive influence on food security status while age had a negative influence on the food security status of maize-based farming households in the Southern Guinea Savannah of Oyo State, Nigeria. This suggests need for specific support to improve maize production

Eighteen (18) lactating she-camels and two mature male for mating were used to determine the effect of Management System on camel calving interval, The camels were maintained under semi-intensive (N = 9) and Traditional management system (N = 9) in North Kordofan State, western Sudan. The experimental females in each group kept together with the bull during 18 months. Blood samples were collected from jugular vein since 4-months post-partum and continue 14 successive months at monthly interval. The serum samples were separated and stored at -20°C and were analysed for progesterone concentration using progesterone specific radio immuno assay (RIA) kits. The results indicated that under semi-intensive system 77.8% of females had been pregnant in 5th - 8th month post-partum and the calving interval varying between 17 to 20 months. Under traditional system and during the experimental period 44.5% of females were pregnant in the 11th – 16th month and the calving interval varying between 23 to 28 months. The ratios of pregnant vs non-pregnant during experimental period in semi-intensive and traditional were 88.9% vs 11.1% and 44.5% vs 55.5%, respectively. Beside the behavioural signs progesterone level consider a good indicator for pregnancy in camels. In pregnant females Progesterone concentration increased significantly during early months. The range of Progesterone concentration varied between 1.10 – 5.76 ng/ml and 0.67 – 2.53 ng/ml in semi-intensive and traditional system, respectively. Our results allow quantifying this impact. With a supplemented diet including 2 Kg of concentrates and 5 kg of roughages per day, the fertility rate will be improved of 67%. It would be possible to expect more than two fold young camels in a year by supplemented 5 kg of concentrates. We conclude that under semi-intensive management dietary supplement during post-partum and early lactation period improves reproductive parameters for instance shortened calving interval.

Phosphorus (P) deficiency is a widespread macronutrient deficiency and is one of the major constraints limiting canola production. Efficient P fertilizer method’s is important for economic production of canola and sustaining of environmental quality. The aim of this research is to investigate P use efficiency (PUE) of canola genotypes at an early growth stage. The experiment was set up as a completely randomized design in a factorial scheme. The factors were ten canola genotypes (Excalibur, Nelson, Vectra, Orkan, Triangel, TKK08-5, Oase, Elvis, Es Hydromel and Licord) and three P rates (0, 50 and 100 mg kg-1). The plant parameters, dry weight of shoot and root varies significantly with P levels in all applications. In general, P concentrations and dry weight of the genotypes are linearly raised by P treatments. The genotype Elvis produced significantly higher shoot dry matter 9.24 g pot-1 at 100 mg kg-1 P rate compared to the other applications. However, without P, dry matter (DM) of genotypes varied between 1.67 to 6.96 g pot-1. Cultivars classified as efficient responsive are: Elvis, inefficient responsive: Nelson, Orkan, Oase, Licord, and efficient nonresponsive: Excalibur, Vectra, Triangel, TKK08-5, Es Hydromel. Plant dry matter can be used for identification of the genotypes which could be adapted to low or high soil P availability conditions at an early growth stage. Nutrient use efficiency and genotypic differences in plants should be considered in order to create an accurate and a balanced fertilizer program as well as improving crop yield in agricultural production system.

The economic evaluation for the production of fruit juice from the Africa star apple otherwise known as ‘Agbalumo’ in the south western part of Nigeria was evaluated using the NPV (Net Present value) and IRR (Internal Rate of Return) methods assuming a uniform cash flow over a 10-year plant life. Sensitivity analysis was conducted by varying the number of production days (330, 300 and 250 days) at 100% plant capacity and varying the plant capacity (100, 85 and 70%) for a 330-day production schedule. Some components of the operating cost reduced with number of days and plant capacities. The production cost and product cost per unit increased with either plant capacity utilization or the number of days. It was observed that product cost/ 500ml Tetra Pak of Agbalumo juice at 85% and 70% stood at ₦37.48 while payback time/profitability percent had better index at 300 and 250 days compared to 330 days of plant operation. The results further indicated that the plant should not be operated for less than 250 days and plant capacity utilization of 70% in the year. Flexibility in the plant capacity utilization in the range of 70%-85% for 330 days shows a good economic performance as well as result of the NPV and IRR for this operating condition.

Published: April 2017

In Ethiopia, the national agricultural research system has been generating and disseminating different agricultural technologies since its establishment in 1966. Although these technologies are meant to increase agricultural productivity, they have to be evaluated for their impact on production and for the benefit that the farmers get out of them. Hence, the main objectives of this study were to examine the impact of technological innovations on wheat production and to decompose the total change in wheat output resulting from the introduction of new technologies into its constituent parts. Cobb-Douglas production function was employed to estimate the regression coefficients under old variety growers, new variety growers, and pooled data cases. Output decomposition model was applied to decompose the total change in output into its constituent parts. The econometric results of this study indicated that, out of 55% of the observed productivity difference between old and new variety grown plots, technological change and change in associated input levels contributed about 24% and 31%, respectively. Of the 31% increment attributed to input use levels, an increased use of herbicides and fertilizers caused the biggest jump in the productivity of improved wheat varieties (15.5% and 11% respectively). The major implications included the need to exploit the full potential of new varieties using recommended input levels, strengthening the research system, fostering coordinated efforts among various actors in agricultural development, and strengthening the technology instrument in rural development and poverty reduction strategies of the country.

Plant growth promoting rhizobacteria are colonized bacterial species that has the capability to improve plant growth by certain direct and indirect means. Environmental factors including both biotic and abiotic stresses are among the major constraints to crop production. In the current study, the effectiveness of microbial inoculation (Bacillus megaterium) for enhancing growth of tomato plants under salt stress conditions has been investigated. Significant improvement in shoot length, root length, leaf surface area, number of leaves, total weight of the shoot and root was observed in tomato plants inoculated with zm7 strain post 15 and 30 days of its application. Zm3, Zm4 and Zm6 strains improved the morphological parameters as compared to the control. Chlorophyll content a, chlorophyll content b, anthocyanin and carotenoid content was increased in tomato plants subjected to Zm7, Zm6 and Zm4 strains. Stress responsive genes; metallothionein and glutothion gene were found highly expressed in Zm7 treated tomato plants as compared to control, untreated plants. Significant correlation of anthocyanin was reported for carotenoids, chlorophyll-b, shoot weight and total weight of seedling while carotenoids were significantly correlated with leaf surface area, root length, chlorophyll-b and anthocyanin. Overall, Zm7 strain proved best for improvement in salt stressed plant’s morphological parameters and biochemical parameters as compared to control, untreated plants.

Published: April 2017

Silage quality and nutritive value of sunflower silages ensiled with different level of fibrolytic enzymes at blooming, milk and dough stages were investigated. Fibrolytic enzyme complex (Viscozyme® L, V2010 Sigma Novozyme) was applied 0, 1, 1.5 and 2.5 ml/kgDM at ensiling. The dry matter (DM) yield increased with each increment of the maturity stage. Dry matter (DM), ether extract (EE) and crude cellulose (CC) contents of silages increased also in each delay in harvesting, while crude protein (CP), NDF and ADF contents of silages were the highest in blooming stage. The pH was higher in sunflower silage harvested at dough stage when compared to blooming stage, while acetic, propionic and butyric acid concentrations were all higher in blooming stage, although there were no differences in lactic acid concentrations among harvesting periods. Although silage structural carbohydrate composition was not significantly affected by any enzyme dose, Dose III enzyme treatment at the dough was associated with the highest concentration of lactic acid. Overall, there was no profound effect of enzyme supplementation on nutritive value and silage characteristics of sunflower silage.
