    Determination of structural properties of agriculture in çanakkale province
    (Namik Kemal University - Agricultural Faculty, 2017) Özpinar, Sakine; Ürkmez, Ünal
    In order to have a more precise description of agricultural farm structure which has significant affect on agricultural mechanizaton properties and characteristics of crop production systems, as well as to assess possibilities for improving production and farming conditions in which crop production is organized, a survey based research was directed at selected group of farms the Çanakkale province. 570 questionnaires have been used to determine structural properties of the agricultural farms registered to farmer registration system in 2012-2013 years. Questionnaire was divided into four sections: General information of the farm, agricultural and structural information, education and the perspectives of future farming. In results, average age in the most of analysed farms was 45 years, and person in each family was 3.72, but 2 persons of them were contributed to the agricultural production. The most of family persons have primary education while the rate of graduates from the university were quite low with 5%. The distribution of the rate of owned and hired agriculture land was the same. The main crops was wheat, tomatoes, olive and horticulture production. 58% of the total agricultural land was irrigated by ground-water, the rest of the land with 43% was non-irrigated, especially under cereal production. The most of farmers have expresed a positive expectation from future due to appropriate agricultural policies such as grant of mechanization equipments. © 2017 Namik Kemal University - Agricultural Faculty.

    Determination of the relationship between orobanche ramosa L. and phytomyza orobanchia kaltenbach, (Diptera: Agromyzidae) on tomato areas of çanakkale province
    (Namik Kemal University - Agricultural Faculty, 2017) Özpinar, Ali; Polat, Burak; Şahin, Ali Kürşat; Özpinar, Sakine
    This study was conducted to determine the infestation rate of broomrape (Orobanche ramose) and population density of its natural enemy Phytomyza orobanchia (Diptera: Agromyzidae) in tomato production areas of Çanakkale province, in 2013-2014 years. It is determined that 58% of tomato production areas of Çanakkale is infested with broomrape and P. orobanchia was acquired from 1-13,6% of this areas. The relationship between broomrape plant density and P. orobanchia was investigated in 10 different tomato parcels with different tomato cultivars. It is determined that, broomrape plants were observed after July 4th and P. orobanchia were acquired from plant samples after August 15th. Adult emergence has continued throughout September, until the end of harvest season. The highest number of P. orobanchia adults was observed from Rio Grande cultivar, which was sowed in May 25th © 2017 Namik Kemal University - Agricultural Faculty. All Rights Reserved.

    Effects of minimum and conventional tillage systems on soil properties and yield of winter wheat (Triticum aestivum L.) in clay-loam in the Çanakkale region
    (TUBITAK, 2005) Özpinar, Sakine; Çay, Anil
    The experiment was conducted during the 2001-2003 cropping period to evaluate the effects of 3 tillage systems, conventional tillage (CT), and minimum tillage with rototiller (MTR) and disc (MTD), on the soil properties and wheat yield (Triticum aestivum L.). Based on 2-year results, soil bulk density at 0-10 cm in the growing period in MTR, CT and MTD was 1.20, 1.34 and 1.24 Mg m-3 respectively. Corresponding values at 10-20 and 20-30 cm were 1.26, 1.29 and 1.21 Mg m-3 and 1.30, 1.27 and 1.40 Mg m-3 respectively. Aggregate size distribution and mean weight diameter throughout the 2 years of the experiment were significantly influenced by the tillage systems. The highest organic carbon was obtained from MTR, followed by MTD and CT. Similarly, total N in the soil was highest in MTR, followed by CT and MTD. Penetration resistance was measured pre-fall tillage, and during the growing period and gave the following values (P < 0.05) for CT, MTR and MTD: 1.65, 1.18 and 1.57 MPa, and 1.33, 1.35 and 1.76 MPa at 18-30 cm. Although there were no statistically significant differences between the tillage systems, grain yield was higher in MTR than in CT and MTD. Consequently, we expect MTR to be more sustainable because of increased grain yield and improving soil physical properties over the long term compared with CT and MTD. © TÜBİTAK.
