Öğe Comparison of Strip Tillage Systems for Sillage Maize Production in Middle Anatolia(Selçuk Üniversitesi, 2018) Çarman, Kazım; Çıtıl, Ergün; Marakoğlu, Tamer; Gür, Kazım; Kırılmaz, HasanStrip tillage might offer an option to produce high silage maize yields at lower costs and improved erosion control compared to full width tillage practices. However, the strip tillage is not included in the agricultural production practice of the farmers in our country. In this study, three different strips tillage application have been used as a alternative to traditional practices (CT). While the machine made by the Maschio Gaspardo (OST) is used in one of the applications of the strip tillage, the other two machines (horizontal (MHST) and vertical shaft rotary tillers (MVST) have been modified and used in strip tillage. The width of the strips of applications varied between 25-28cm. As a depending on strip tillage applications, 35-40 % of soil surface was tilled. While the penetration resistance of the strip tillage applications ranged from 0.45-1.91MPa, the surface roughness of the strips was found to be about 11 %. Results of fuel consumption were 4.92, 1.82, 1.3 and 0.73 l da-1for the full width tillage, OST, MVST and MHST respectively. Seedling emergence degree was approximately 6 % higher for MVST and OST compared to CT. An average increasing of 12 % plant emergence rate index (ERI) under MVST compared with other applications was found.Öğe Determination and Comparison of Soil Deformation Areas, Stubble Burial Rates and Stubble Quantities of Single-Acting Disc Harrow Driven by the Tail Shaft and Single-Acting Disc Harrow that Takes its Movement from the Soil(Selçuk Üniversitesi, 2023) Çıtıl, Ergün; Marakoğlu, TamerIn this study; soil-driven single-acting disc harrow and PTO-driven single-acting disc harrow machines were used. The single-acting disc harrow, which moves from the soil, was tested with two different disc diameters (610 mm and 660 mm) and three different direction angles (16o - 23o and 30o ), while the single-acting disc harrow, which moves from the tail shaft, was tested with two different disc diameters (610 mm and 660 mm), three different direction angles (160 - 230 and 300 ) and three different disc speeds (104.97-119.97 and 143.96 min1 ). As a result of the treatments, the effects on soil moisture retention, deformation area, stubble burial rate and stubble amount were compared for both machines. It was determined that the cutting width and working depth increased with the increase in disk diameter and direction angle, and the deformation area increased accordingly. The lowest amount of stubble was obtained from D1N3Y3, D1N3Y2 and D2N3Y3 treatments as 20.67 g m-2 , 22.67 g m-2 and 25.33 g m-2 , respectively. The highest stubble burial rate was 87.30%, 86.07% and 84.02% in D1N3Y3, D1N3Y2 and D1N2Y3 treatments. While the lowest u/v ratio was obtained from D1N1Y1 with 3.03, the highest u/v ratio was obtained from D2N3Y3 with 4.63, the lowest skidding rate was obtained from D1N3Y1 with 3.17% and the highest skidding rate was obtained from D2Y3 with 11.99.Öğe Effect of different seed bed prep aration systems on wheat yield and yield components in midd le anatolia(National Centre for Agrarian Sciences, 2014) Akgün, Necdet; Marakoğlu, Tamer; Çarman, K.This research was conducted at the experimental field of Konuklar Agricultural farms of TİGEM between 2006-2009 for determination the effect of four different tillage systems on yield and yield components of bread wheat (Triticum aestivum L.) variety under Middle Anatolian conditions of Turkey.

Compared with traditional approaches, fuzzy logic is more efficient in linking the multiple inputs to a single output in a non-linear domain. The main purpose of this study is to investigate the relationship between cultivator shares working parameters to soil loosening and draft efficiency, and to illustrate how fuzzy expert system might play an important role in prediction of these. Experimental values were taken in soil bin The trials were conducted in different working depths and forward velocities of cultivator shares. In this paper, a sophisticated intelligent model, based on Mamdam approach fuzzy modeling principles, was developed to predict the changes in soil loosening and draft efficiency of tool. The fuzzy model consists of 25 rules In this research, a Mamdam max-min inference for inference mechanism and the center of gravity (aneroid) defuzzifier formula method for defuzzification were used as these operators assure a linear interpolation of the output between the rules. The verification of the proposed model is achieved via various numerical error criterias. For all parameters, the relative error of predicted values was found to be less than the acceptable limits (10%).Öğe Hububat ekim makinelerinde tek diskli gömücü ayakların tohum dağılım düzgünlüğüne ve toprak deformasyonuna etkileri(Selçuk Üniversitesi Fen Bilimleri Enstitüsü, 2005-01-06) Marakoğlu, Tamer; Konak, MustafaBu çalışmada, hububat ekim makinalarında tek diskli gömücü ayakların tohum dağılım düzgünlüğüne ve toprak deformasyonuna etkileri araştırılmıştır.

Sustainable agricultural production is achieved with proper soil management. Tillage is considered to be one of the largest operations, as the most energy need in agricultural production occurs in tillage. The main purpose of this study is to investigate the effects of chisel tine on draft force and disturbed soil area and estimate them using artificial neural networks (ANN) and multiple linear regression equations (MLR). The experiments were carried out in a closed soil bin filled with clay loam soil at an average moisture content of 13.2% (on dry basis). The draft force and disturbed soil area were evaluated as affected by the share width at two levels (60 and 120 mm), forward speed at four levels (0.7, 1, 1.25 and 1.5 ms-1 ) and working depth at four levels (160, 200, 240 and 280 mm) at three replications. The draft force varied from 0.5 to 1.42 kN, depending on the controlled variables, while the disturbed soil area varied from 260 to 865 cm2 . Test results show that share width, forward speed and working depth were significant on the draft force and disturbed soil area. Input variables of the ANN models were considered share width, forward speed and working depth. In prediction of required draft force and disturbed soil area respectively, on account of statistical performance criteria, the best ANN model with coefficient of determination of 0.999 and 0.998, root mean square error of 0.010 and 0.016 and mean relative percentage error of 0.960 and 1.673 was better performed than the MLR model.Öğe Prototip ekim makinesi ile sıvı ahır gübresi ve mineral gübre uygulamalarının azot kayıpları ve verim parametreleri açısından değerlendirilmesi(2012) Özbek, Osman; Marakoğlu, Tamer; Çıtıl, Ergün; Çarman, KazımBu çalışmanın amacı prototip bir hububat ekim makinesi ile mineral gübre ve sıvı ahır gübresinin farklı uygulamalarında azot kaybı, verim parametreleri ve yakıt tüketimi üzerine etkisi araştırmaktır.Yukarıda belirtilen amaca ulaşma yolunda gerçekleştirilen denemeler üç farklı uygulama şeklinde yürütülmüştür.
