The Impact of a Centrifugal Pump in the Fuel Consumption of Agricultural Tractors with Different Nominal Capacities Driven with 540 and 540e PTO Options
(Selçuk Üniversitesi, 2018 Ağustos) Çiftçi, Oktay; Çalışır, Sedat
In this study examined that PTO power and torque values, tractor hourly fuelconsumption and tractor specific fuel consumption of three tractors with different nominal loads driven with a 540 and 540E min-1 power take-off (PTO) anda centrifugal pump with a reduction gear.A 150 mm intake line with 1/4 transmission system driven with a PTO, horizontal shaft snail type centrifugal gear pump with 125 mm nominal diameterwith outlet line was used in the study. The pump was driven by three differentpower tractors (New Holland TD65D, TD90D and TD110D) under laboratoryconditions with 540 and 540E PTO options. The pump was operated at constant shaft speed (2160 min-1) during all tests.PTO torque, PTO power, fuel consumption and specific fuel consumptionparameters were determined for both PTO applications in the experiments. Thepump operations in all three tractor revealed that there was no change in PTOtorque values as a result of experiments carried out with 540 and 540E rpmwhile the values fuel consumption in the 540E rpm application (14% forTD110D tractor, 34% for the TD90D tractor, 11% for the TD65D tractor) andspecific fuel consumption (17% for the TD110D tractor, 36% for the TD90Dtractor, 13% for the TD65D tractor) were less than the values in the 540 rpmapplication. This is the result of the application of different engine speeds forthe two PTOs.Taking all parameters into account, it has been concluded that the 540E application provides certain advantages in terms of fuel consumption for many toolsand machines operated with PTO compared to the 540 application. Accordingto this result, the 540E application is proposed as an important alternative tothe 540 application for tools and machines of similar capacity and specifications used in this study.

Effects of Different Manganase Sources and Concentration in the Diets on the Performance, Reproductive Characteristics and Some Blood Parameters of Breeder Japanese Quail
(Selçuk Üniversitesi, 2018 Temmuz) Gökmen, Seyit Ahmet; Bahtiyarca, Yılmaz
An experiment with breeder Japanese quail was conducted to determinethe effects of different manganese (Mn) sources and levels in diet on the performance, reproductive characteristics and blood constituents during for five28 day periods. In the experiment, a total of three hundred and sixty quail(female:male ratio, 2:1) at seven weeks of age was fed on diets containing 0,60, 120, 180 and 240 mg kg-1 Mn levels from inorganic (MnSO4.H2O) or organic (Mn-amino acid chelate, Glycinoplex-Mn) source. Ten treatments combination of 2 Mn source and 5 Mn levels in 2X5 factorial arrangement wereused with six replicate consisting of 4 female and 2 male quail each. The dietsin mash form and water were given as adlibitum and 16 hours ligthting wasprovided in a day. In the experiment, final body weight (BW), body weightgain (BWG), livability, hen day egg production (EP), egg weight (EW) and eggmass (EM), feed consumption (FC) and feed conversion ratio (FCR), chickweights at hatching, fertility, hatchability of eggs set (%), hatchability of fertileeggs (%), embryonic mortalities and glucose, total cholesterol and protein,albümin, BUN, GGT, SGOT, SGPT, calcium, phosphorus and magnesiumcontent of blood serum were measured. Dietary Mn source and levels as the main factor did not significantlyaffect the performance and reproductive traits which was measured in theexperiment. Nevertheless the interaction between source and levels of Mn hada significant effect on average EW and chick weights at hatching over theexperimental period. Egg weight of quail fed diet with 60 mg kg-1 Mn frominorganic form was higher (P<0.01) than those of quail fed with 0, 180 and 240mg kg-1. Mn from inorganic and 0, 60, and 240 mg kg-1 Mn from organic form,again chick weights at hatching of quail fed diet with 60 mg kg-1inorganic Mn,was significantly higher (P<0.05) compared with quail fed with all other levelsof inorganic and organic Mn. In the experiment, while dietary Mn levels didnot significantly affect any blood parameters, the serum glucose level of thequail fed with organic Mn was significantly higher than that of the quail fedwith inorganic Mn and also serum phosphorus level of the quail fed with inorganic Mn was higher than that of the quail fed with organic Mn (P<0.01). Theinteraction groups between source and levels of Mn significantly affected thetotal protein, albumin and calcium levels of blood serum (P<0.05). Theseparameters were found to be higher in quail fed diets containing 60 mg kg-1 Mnin inorganic form than quail with some other diets. These results have shownthat addition of 60 mg kg-1 Mn in inorganic form to breeder quail diets (containing 21.56 mg kg-1 Mn, found in analysis) based on corn + soybean mealmay be beneficial.

An Approach to Comparing Different Land Evaluation Methods with NDVI
(Selçuk Üniversitesi, 2018 Temmuz) Dedeoğlu, Mert; Özaytekin, Hasan Hüseyin; Başayiğit, Levent
Land evaluation is a necessary process for determining the potential cabilities of the land under different uses and for sustainable soil fertility. Today, many land evaluation models have been developed and using for this purpose. But the availability of models is constantly being investigated by the researcers. In this study, Storie Index (SI) and Productivity Index (PI) models were compared with NDVI values which are a remote sensing analysis in Konya Beşgözler agricultural field using GIS. In the results of the study, SI land evaluation model was determined with higher accuracy coefficient (r2 : 0.86) compared to PI model (r2 : 0.29) in terms of the ability of the soil cability based on the density of vegetation and the use of this model is recommended for Arid region soils.

The Effect of in-ovo Injection of Lactobacilla Rhamnosus on Hatching Traits and Growth Parameters of Quails
(Selçuk Üniversitesi, 2018 Temmuz) Abdulqader, Abbas Fadhıl; Aygun, Ali; Maman, Abdoulaziz Hamissou; Olgun, Osman
The aim of this study was to investigate the effect of in-ovo injection ofLactobacilla Rhamnosus (0, 16x103, 32x103and 48x103cfu) as probioticsource on hatching parameters and growth performance of quails. In this, atotal of 400 quail hatching eggs, were randomly distributed among 4experimental groups. Each experimental group contained 4 replicates of 25eggs each. In-ovo injections of Lactobacilla Rhamnosus into quail eggs did notstatistically affect incubation characteristics and some tissue weights. A highamount of Lactobacilla Rhamnosus injection into the breeder quail eggsnegatively affected live weight and live weight gain. As a result, it can be saidthat low or medium levels Lactobacilla Rhamnosus injection into quail eggshave no effect on incubation and growth parameters of quails.

(Selçuk Üniversitesi, 2018) Aydoğan, Seydi; Şahin, Mehmet; Göçmen Akçacık, Aysun; Demir, Berat; Hamzaoğlu, Sümeyra; Taner, Seyfi
This study was conducted with 7 bread wheat varieties in rainfed and irrigatedconditions at Bahri Dagdas International Agricultural Research Institute as arandomized complete block design with three replications. Grain yield, thousand kernel weight, protein ratio, Zeleny sedimentation value, bread weight,bread volume and farinograph traits were investigated. Significant differencesbetween the varieties were determined in terms of investigated traits in rainfedand irrigated conditions. Bread volume, farinograph development time, proteinratio and Zeleny sedimentation values in rainfed conditions were higher thanvalues in irrigated conditions. Bread volume, farinograph development time,protein ratio and Zeleny sedimentation were determined as 507 cm3, 9.2 min,13.6% and 46.8 ml in rainfed conditions and 495 cm3, 6.7 min., 12.3% and44.0 ml in irrigated conditions respectively. According to the results; the effectof the growing conditions were found statistically significant on wheat quality.
