The Effect of Different Sowing Densities and Nitrogen Doses on Yield and Yield Components in Triticale (X Triticosecale Wittmack)

摘要

This study was carried out in Namik Kemal University, Agricultural Faculty, Field Crops Department application and research area with randomised split block desing with three replicoturn. In the study, it is aimed at determination of effects of diferrent 6 sowing densities (350 seed/m~2, 400 seed/m~2, 450 seed/m~2, 500 seed/m~2, 550 seed/m~2, 600 seed/m~2) and 6 nitrogen doses ( 0 kg/da, 6 kg/da, 9 kg/da, 12 kg/da, 15 kg/da, 18 kg/da ) applications on yield and yield components in Karma-2000 triticale cultivar. The increases of sowing densities did not cause significant changes in averages of plant height, number of spikelets per spike, number of grains per spike, grain weight pers pike and harvest index. Although grain yield increased up to 550 seed/m~2 sowing density, after that has decreased. The averages of plant height, number of spikelets per spike, number of grains per spike, grain weight per spike, harvest index and grain yield increased up to 12 kg/da nitrogen dose. In the result of study, it can said that optimum sowing density and nitrogen dose shoud be 550 seed/m~2 and 12 kg/da nitrogen dose for the highest triticale yield in Thrace ecological conditions.
