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. Conventional, reduced tillage, direct and direct seeding + herbicide were applied in the experiment. According to the results of the research, seeding systems constituted significant differences for grain yield, spike length, spikelet and kernel number per spike, kernel weight per spike, harvest index and test weight. The grain yield, plant height, spike length, spikelet per spike, kernels per spike, kernel weight per spike, spikes per m2, harvest index, 1000 kernel weight and test weight varied from 2660.9 to 3493.3 kg.ha1, form 78.53 to 80.58 cm, from 7.41 to 8.42 cm, from 14.78 to 16.23, from 25.64 to 30.54, from 0.70 to 0.99 g, from 636 to 677, from 26.67 to 29.20%, from 26.94 to 28.93 g and 72.27-74.35 kg respectively. The results revealed that direct seeding can be offered for wheat production in Middle Anatolian Region. © 2014, National Centre for Agrarian Sciences.

The test tool variables included rake angle to the horizontal of 12.5, 17.5 and 22.5°, working epths of 70, 110 and 150 mm and forward velocity of 1.08, 1.55 and 2.08 m sec-1. Measurements were taken of draft force and disturbed area of soil by the cultivator share. The resulting draft force was increased with increasing rake angle, forward velocities and working depth. The draft force in different trials varied from 42 to 202.5 daN. The area disturbed of soil was larger when tool rake angle, forward velocity and working depth were increased. The greatest disturbed area occurred at rake angle of 22.5°, forward velocity of 2.08 m sec-1 and depth of 150 mm. The soil loosening increased with rake angle and forward velocity but loosening decreased with increased working depth. The soil loosening varied from 21.07 to 40.45%.Öğe Some Physical Properties of Lentil Seeds(ACADEMIC PRESS LTD, 1996) Çarman, K.Several physical properties of lentil seed were evaluated as a function of moisture content. The average diameter, thickness, unit mass and volume of seed were 6.64 mm, 2.65 mm, 0.070 g and 49.08 mm(3) respectively at 6.5% m.c.d.b. Studies on rewetted seed showed that as moisture content increased from 6.5 to 32.6% d.b., bulk density decreased from 1190 to 935 kg/m(3), porosity increased from 27.4 to 32.0%, projected area increased from 56 to 82 mm(2) and terminal velocity increased from 10.95 to 12.06 m/s. The static and dynamic coefficients of friction of lentil seed against galvanized sheet metal, plywood and rubber surfaces increased with moisture content in the range from 6.5 to 32.6% d.b. The largest coefficient of friction was against a rubber surface, ranging from 0.374 to 0.532. The effect of moisture content was as great as or greater than the difference between the surfaces.
