Because of using sulphur free fertilizer, rice crop facing tremendous sulphur (S) deficiency throughout the world as well as in Bangladesh. However, farmers of Bangladesh often overlook the importance of sulphur fertilization on rice yield. Therefore, the present study was conducted to investigate the influence of different levels of sulphur on growth, yield attributes and uptake of N, P, K and S by grain and straw of BRRI dhan41 rice variety. The experiment was laid out in randomized complete block design with three replication and eight treatments including control. The result of the study revealed that the highest plant height, panicle length, filled grain was found in T1 (50% RFD of S) treatment, while the utmost number of effective tiller and straw yield was recorded in T5 (150% RFD of S) treatment. Interestingly, maximum grain yield as well as uptake of N, P, K and S by grain and straw was significantly higher in T6 (175% RFD of S) treatment. The highest grain yield of T6 treatment might be due to maximum nutrient use efficiency. However, in all cases control treatment (T0) gave the worst result. The present study clearly indicates that higher rates (175% of the recommended dose) of S along with other fertilizers may be recommended for better growth and yield of BRRI dhan41 in Bangladesh soil.

Oseni Kadiri | John Temitope Kolawole | Babatunde Olawoye | Alasa Paul Kadiri
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.

Pylyp Petrov | Yaroslava Zhukova | Demikhov Yuriy
The article focuses on the impact of different dairy management types on quality characteristics of organic and conventional milk. The study was conducted during 9 months (spring-autumn), raw milk samples were collected from organic and conventional dairy farms from two Ukrainian regions. The milk samples were analyzed for dry matter, total protein and non-protein nitrogen, ammonia content and values of stable isotopes 13С/12С were measured in fat and milk protein fractions. The values of dry matter, total protein, true protein and non-protein nitrogen content do not represent a statistically significant effect of farming type. The values of ammonia content, ammonia/non-protein nitrogen and ammonia/total protein ratios were statistically significant and reflected the impact of farming type which is, probably, linked with different protein content in cows’ diet. Conversion of some parameters on the dry matter allows more precise differentiation among types of milk, including statistically significant differences (e.g. total protein and ammonia content). The values of δ13C in fat fraction (-26.00‰) and protein fraction (-22.89‰) of organic milk were statistically significant differed in comparison with conventional milk (-23.14 ‰ and -19.15‰ respectively), due to the high amount of maize in the diet on conventional farm. The values of Δδ13C also were statistically significant: 3.99‰ in conventional milk and 3.11‰ in organic. It was established that conventional milk has a greater range of the different parameter seasonal variations than organic milk.

Erkan Eren | Gölgen Bahar Öztekin | Yüksel Tüzel
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.

The majority of farm households in Turkey and especially the Eastern Anatolia are still based on low-input semi subsistence agriculture and livestock production. Despite a slow decline in recent years, agriculture and livestock production remains a major employer in Turkey and it is a significant contributor to the country’s gross domestic product, GDP. Whist Turkey is one of the EU candidate countries, is self sufficient in food production and Turkish agriculture is poorly structured inefficient, with farming in the Eastern Anatolia being mainly subsistence farming. Yet, these traditional rural structures combined with poor access to low level of education and low level of off-farm unemployment problem makes the situation more complicated and unsustainable. The best way to promote sustainability, better and higher production of Eastern Anatolian and rural Turkey is to invest in the local people, villages through improved, continuing and effective agricultural and livestock programs in particular. Investment in human capital especially in the rural areas leads to more employment opportunities through entrepreneurship and innovation in organic agriculture and livestock production. A holistic approach to developing and improving supply chains could unlock the potential for sophisticated, state-of-the-art organic agriculture and livestock producers and businesses in the region to become EU and global players. Eastern Anatolian livestock producers and the farmers have the ambitions to take part in future progress because the region is naturally organic not by design but default. It is for sure that present potential of the region has not been fully determined and utilized. EU has greatly benefited from previous enlargements economically, politically and socially. When European Union (EU) and Turkish Government relations considered and accession of Turkey to EU would be the logical consequence of the previous accessions. The screening on chapter 11 (Agriculture and rural development) is one of the important criteria and Turkey is working on to meet these benchmarks.

In this study, radioactivity and heavy metals accumulations in Agaricus campestris mushroom collected from Kahramanmaraş and Erzurum provinces was determined. HPGe gamma detector was used for the determination of radioactivity concentrations. Heavy metal content was measured using a ICP-MS. As radioactive element; natural (238U, 232Th 40K) and artificial radionuclide (137Cs) concentrations were determined. The values of the committed effective dose were calculated. Same measurements were made in soils. Absorbed dose and excess lifetime cancer risk were calculated. Amount of Mg, Al, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Cd, Pb206, Pb207 and Pb208 as heavy metals of mushrooms were determined. 238U, 232Th, 40K activity concentrations of mushroom collected from Erzurum was determined as 12.1 ± 0.8, 11.7 ± 0.9, 497.7 ± 17.8 Bq/kg, respectively and 137Cs was not detected by system. 232Th and 40K activity concentrations of mushroom collected from Kahramanmaraş was determined as 13.4 ± 0.5, 134.9 ± 6.3 Bq/kg, respectively, 238U and 137Cs was not detected by system similarly. The value of the committed effective dose collected from Erzurum and Kahramanmaraş were calculated as 75 and 29 μSv respectively and these values were found lower than 290 μSv accepted as world average. Absorbed dose and risk of lifetime cancer for Erzurum was determined as 37.39 nGy/h, 16.5 x 10-5; absorbed dose and excess lifetime cancer risk for Kahramanmaraş was determined as 30.92 nGy/h, 13.3 x 10-5 respectively. Amount of daily intake for each heavy metal was calculated. Radionuclide activity concentrations and accumulations of heavy metal were not founded threaten level to healthy, except from arsenic As (0.025 and 0.039 mg/kg) in mushroom collected from both provinces. They were found a bit higher than upper limit (0.015 mg/kg) in report which is prepared World Health Organization (WHO) and Food and Agriculture Organization of the United Nations (FAO) jointly.

Post-harvested blackberry, raspberry and strawberry fruits were immediately treated with 1% and 2% calcium chloride by immersion at 20 ± 1°C for 2.5 min and kept for 8 days at 0 ± 0.5°C and relative humidity (RH) 90 ± 5%. The application of calcium did not significantly effect on total titratable acidity, pH and total soluble solids. Maximum weight lost was observed for untreated berries and minimum lost was observed for fruits treated with 2% calcium chloride. After storage, ascorbic acid content was significantly higher in samples of blackberry, raspberry and strawberry fruits subjected to 2% calcium chloride dip. Treatment of blackberry, raspberry and strawberry fruits with calcium chloride had a positive effect on retention of total polyphenols content during the storage period. Depletion of antioxidant capacity of untreated fresh blackberry fruits during 8 days cold storage was 25%; raspberries and strawberries - 34 and 26 % respectively. Whereas depletion of antioxidant activity in the 2% calcium chloride treated samples of these fruits was 8, 22 and 11% respectively. In case of storage of untreated blackberry fruits content of cyanidin-3-O-monoglucoside decreased by 6.33 mg per 100 g of fruit. While, in fruit samples treated with 1 and 2% calcium chloride content of cyanidin-3-O-monoglucoside decreased by 32.06 and 11.35 mg per 100 g of fruit, respectively. Content of pelargonidin 3–O- monoglucoside increased by 2.29 mg per 100 g of the untreated blackberry fruits and by 26.87 and 8.45 mg per 100 g of fruits treated with 1 and 2% calcium chloride respectively. Change of content of cyanidin 3–O- (6 - p – coumaroyl - glucoside) in blackberry fruits was not statistically significant.

Non-dairy probiotic functional foods are receiving considerable interest recently owing to the inability to cause allergy in certain segments of the population. Studies on probiotication were carried out to determine the suitability of kunun-zaki as food matrix for production of probiotic beverage using single and mixed culture of Pediococcus acidilactici KU7, Pediococcus pentosaceus CREC5 and Lactobacillus rhamnosus GG. Probioticated and un-probioticated kunun-zaki samples were designated PKZ and UPKZ, respectively. There was a significant difference in the viable count during storage. Viable counts of the LAB strains decreased with increasing storage time with P. acidilactici KU7 having the highest viability at the beginning and end of storage (3.43 ± 0.06 and 0.93± 0.12 x108 cfu/ml). There was a decrease in pH of the PKZ samples within the 1st and 3rd week with corresponding increase in lactic acid production (71.16 ± 0.01 – 441.39 ± 0.01). Marked increase in pH and a decline in lactic acid were observed at the 4th week of storage in all samples. Total soluble solids content of the beverage was observed to decrease with increasing storage time ranging from 8.25 ± 0.01-4.97± 0.01. There was no significant difference in pH and total soluble solids of UPKZ and colour of the PKZ and UPKZ samples during storage. All the PKZ samples were able to inhibit the growth of selected pathogens with marked variability amongst the samples. The UPKZ sample also showed slight inhibitory activity. The samples showed a decline in proximate and mineral composition at the end of storage. Sensory evaluation showed the PKZ samples were preferred over the UPKZ samples. This study shows that probioticated kunun-zaki can serve as a suitable non-dairy alternative to dairy probiotic formulations and would be of health benefits to potential consumers.

Yavuz Topcu | Mehmet Toparlak | Muhlis Macit
The aim of the study is to evaluate all the factors determining the milk production and yield decisions with regard to the nutrition and feeding programs affecting the integrated management strategies on the success of the dairy farms with culture breed cattle under the pasture-based and indoor barn-based production systems. For these aims, data obtained from the individual interviews conducted at the dairy farms with 100 culture breed cattle were used for Principal Component and Multiple Regression Analyses. The results of the study highlighted that while there were linear positive relationships among liquid assets of farms value, concentrate feed and fodder intake of dairy cattle, milk sale price, forage crop support, additional feeding and their types at pasture and milk yields per dairy cattle at the dairy farms; there were inverse relationships among hay intake of dairy cattle, lactation period, pasture planning, culture breed cattle support and those. The farmers could increase the successes of the dairy farms by increasing the technical and economic effectiveness under the integrated management pattern approaches at those with culture breed cattle.
