The effects of difrent sowing rates and sowing methods on grain yield and some grain yield components in Tarm 92 barley variety

This study was conducted to determine the effects of different seeding rates (200, 300, 400, 500, 600 ve 700 seed m-2) and sowing methods (sowing to the rows, broadcasting to seeding depth and contrary rows with 90°) on grain yield and some yield components of barley Tarm-92 variety (Hordeum vulgare L. conv. distichon) under Kırşehir ecological condition in 2013-2014 winter growing seasons. In the current study, seeding rates and sowing methods significantly affected grain yields and yields components. In the study, the increasing of seeding rates decreased tillering, number of grains per spike and thousand grain weight, while the increases was obtained in number of spike, plant height, spike length and grain yield. In the study, 90 ° cross-seeding sowing method compared to other methods of seeding has been greater on yield and yield components. The highest grain yield with 271.6 kg da-1 was obtained at 600 seed m-2 and sowing to contrary rows with 90°. The lowest grain yield with 113.3 kg da-1 was obtained at 200 seed m-2 and sowing to broadcasting to seeding depth.
