    Conservation and conventional tillage methods on selected soil physical properties and corn (Zea Mays L.) yield and quality under croppin system in Turkey
    (2010) Sessiz A.; Alp A.; Gursoy S.
    This study was conducted to determine the effects of conventional and conservation tillage on the some soil physical properties, penetration resistance (PR), seedling emergence rate, yield and yield components under southestern of Turkey conditions. The experiments were carried out at 2003 and 2004 years in a clay loam soil. Six different soil tillage methods in corn production were tested. The experiment was performed in randomized block design with six treatments and each treatment consists of three replications. No significant (p>0.05) treatment differences in seedling emergence were found between the tillage treatments for both years. Plant height was found significant between years while treatment effects were not significant. However, the highest plant height was obtained in 2004 under CT tillage method. The stalk thickness was found significant between years while treatment effects were not significant. The cob length was not found significant between years and treatments.The lowest cob length was obtained under NT method. It was found that yield was significantly (p<0.01) different between years. The yield in the second year was found to be higher than that of the first year. The highest yield was found in CT method as 678.00 kg/da and the lowest yield was found in RT4 method as 535.66 kg/ha in year 2003. The highest yield was found in CT method as 778.66 kg/da and the lowest yield was found in RT4 method as 642.33 kg/ha in year 2004. The highest fuel comsumption was obsorved as 33.48 Lha-1 in conventional method (CT) whereas the lowest value was found in direct seeding method as 6.6 Lha-1.

    Cutting parameters of some grape varieties subject to the diameter and age of canes
    (Parlar Scientific Publications, 2019) Esgici R.; Goksd Pekitkan F.; Ozdemir G.; Guzel E.; Sessiz A.
    Grape is an important product for the economy of Turkey and it will continue to play an important role in worldwide grape production due to its large number of varieties, favorable ecological conditions and large production areas. However, pruning and harvesting of grape berries are performed manually with a labor intensive procedure. Therefore, production cost is very high and labor efficiency is low in vineyards. However, pruning and harvesting are the most critical operations in vineyard management. Information regarding the cutting of canes of different grape varieties is very important for a proper harvest machine design as well as the efficient use of energy. In this study, cutting force and cutting energy were measured by considering the factors of grape canes diameter and age of canes. One and two year old grape canes from the Genc Mehmet, Bogazkere and Okuzgozu local varieties were used as experimental material. The canes were obtained from a commercial vineyard in the Diyarbakır province located in southeastern Turkey. Lloyd, LRX plus series, materials testing machine was used for cutting tests. Statistically significant differences were determined between the cutting properties of grape varieties. The cutting force and cutting energy increased with increasing diameter and age of canes. © 2019 Parlar Scientific Publications. All rights reserved.

    Tillage effects on sunflower (helianthus annuus, l.) emergence, yield, quality, and fuel consumption in double cropping system
    (2008) Sessiz A.; Sogut T.; Alp A.; Esgici R.
    The relation between crop growing and soil tillage treatment are play important role in agricultural production. Soils under conventional tillage (CT) generally have lower bulk density and associated higher total porosity within the plough layer than under no tillage (NT). No-till farming can reduce soil erosion, conserve soil moisture and minimize labor and fuel consumption. The aim of this study were to investigate the effects of conventional, reduced and notillage methods on soil physical properties, sunflower yield and yield components, protein and oil content and fuel consumption in Southeastern of Turkey. Six tillage methods for the second crop sunflower were tested and compared each other within after lentil harvesting at 2003 and 2004 years in a clay loam soil. According to results, the first year, the bulk density had decreased from 1.29 to 1.09 g cm-3, the second year the ?b had decreased from 1.41 to 1.23 g cm-3. Differences between years and tillage methods in terms of yield were found signifi cant (p<0.05). However, no differences were found between the NT and CT. There were also no signifi cance differences in content of protein, oil and ash among six tillage methods. The highest fuel consumption was measured in conventional method (CT) whereas the lowest value was found in direct seeding method as 33.48 L ha-1 and 6.6 L ha-1, respectively.
