  Contract Farming in Buckwheat Cultivation

  Adanacioglu, Hakan; Doğan, Nilgün

  Contract farming is a deal between a producer and a buyer regarding cultivation of an agricultural product characteristically. In reality, terms and conditions of these contracts can alter dramatically. It can refer to those arrangements involving public firms, government organisations or NGOs and can also refer to private schemes. In this paper, it is only focused on contract farming on arrangements between farmers and private actors. In recent years, buckwheat has gained increasing notice as a promising functional food, owing to its several human health issues and lack of gluten. This study examines buckwheat farmer’s involvement in contract farming in districts of Gümüşhane province which is in the northeast of Turkey. An empirical analysis of the contract farming regarding the buckwheat farmers and postharvest practice has been provided. The survey was conducted in Kelkit, Köse and Şiran districts as only production places of the buckwheat in the province. Data collected from 30 farmers who are engaged in contract farming model. According to data, issues of the contract farming, marketing channels of the buckwheat and perspectives of the farmers for the buckwheat production with contract farming are addressed. The findings of this study reveal that the contract farming model, mostly eliminates the marketing-related concerns of the farmers in the region. Perceive benefits derivable from beginning to buckwheat contract farming was measured based on the following proposals (the commitments to purchase product, the market guarantee, the compliance with the contract terms, purchasing at the agreed price and timely payment) was evaluated using 5 point likert scale. As a result, buckwheat contract farmers should be monitored by the contract buyer for the continuity of the production.

  Growth-Development, Yield and Quality Characteristics of Aronia Varieties Grown in Pots

  Çelik, Hüseyin; Karabulut, Besim; Uray, Yahya

  This study was carried out to determine the growth, development, yield and some quality characteristics of Nero and Viking Aronia varieties grown in open field and pot in Samsun ecological conditions. Three-year-old Aronia plants were planted in 80-liter pots containing a 1:1:1 (v/v) mixture (barnyard manure+soil+sand) and 5 plants were included in each replication. Number of shoots, flower buds and clusters, berry weight (g), yield (g/plant), firmness (N), number of fruits per cluster, must yield (ml/100g), TSSS (%) and pH values were measured in Aronia cultivars. In addition, monthly shoot growth rate (cm/month) was determined and phenological observations recorded. According to Viking and Nero Aronia varieties, the number of shoots (7.8 and 7.6 pieces), the number of flower buds (22.63 and 22.85 pieces), the number of clusters (45.06 and 44.80 pieces), the weight of berry (0.82 and 0.79 g), the fruit number in the bunch (21.45 and 21.53 pieces), berry firmness (4.90 and 5.35 N), amount of must (49.67 and 54.00 ml/100 g) and TSS (17.07 and 16.47) and pH values (3.65 and 3.52) were found to be close to each other. Bud burst (10 March), flowering (26 April), berry set (12 May) and harvest time (24 August) were also similar in cultivars. It was also revealed that while the shoot length was 97.47 cm and 95.47 cm on March 11, respectively, in Viking and Nero varieties, it reached 124.73 and 120.73 cm in August, five months later.

  Root Architecture and Development of American Grape Rootstocks\rGrafted with Foxy Grapes (Vitis labrusca L.) Cultivars

  Çelik, Hüseyin; Karabulut, Besim; Kose, Bulent; Uray, Yahya; Türk, Fatma

  One of the important factors affecting rootstock performance in grafted grapevine production is root structure and its ability for\rdifferent soil. In the present study, foxy grape varieties registered for the first time in the Black Sea Region in Turkey by the\rselection, and several American grape rootstocks were bench grafted. In this study; it is aimed to examine the root architecture of\rfoxy grape grafted saplings for their root architecture and the development of rootstocks. In the experiment ‘Rizessi’, ‘Çeliksu’,\r‘Ülkemiz’ and ‘Rizellim’ foxy grape cultivars grafted on 140Ru, SO4 and 110R rootstocks. WinRhizo root analysis program (Regent\rInstrument Inc. Canada, ver.2013) was used to determine rootstocks' architecture and development of grafted vine saplings. Roots\rprepared for scanning were placed on the scanning part of the device and transferred to the computer context. Root length and\rmean root diameter are two of the essential features that reveal the root architecture of rootstocks. In the study, root length (cm),\rroot surface area (cm2), root diameter (mm), root volume (cm3), root tip number (piece), root branching number (piece), and root\rintersection number (piece) were determined. Total root length was determined between 330.05 - 595.40 cm ('Rizellim'/SO4 and\r'Çeliksu'/140Ru) and mean root diameter of 2.04 - 3.13 mm ('Çeliksu'/140Ru and 'Rizessi'/110R). Negative relationships were found\rbetween root length and mean root diameter. Among the rootstocks, the highest root surface area was 399.67 cm2, root volume\rwas 29.32 m3, the number of root tips was 1605.75, the number of root forks was 5421.89, and the number of root crossing was\r671.61 on 110R rootstock. In all combinations obtained as a result of the study, it was determined that the rootstocks showed\rgood root development and were in harmony with the new foxy grape cultivars.
