Orta Anadolu Ekolojik Şartlarinda Farkli Bitki Popülasyonlarinin Ekmeklik Buğdaylarda Tek Bitki, Ana Başak Verimi Ve Bazi Verim Bileşenleri Üzerine Etkisi

Özet

This study was conducted to determine effect on single plant and single plant per main spike yield and some yield components in Ahmetaga
and Bezostaja-1 bread wheats having more and few tillers, respectively as a function of tillering of ecological conditions and different plant
populations in Konya ecological conditions during 2007-2008 and 2009-2010 growing seasons. Experimental design was “in randomized
complete block design as three factors” with three replications. In this study, wheat seeds were planted in 7 intra row spaces “normal, 2.5, 5.0,
7.5, 10.0, 12.5 and 15 .0 cm”. It was determined that there were statistically significant differences in effect of ecological conditions (years), intra
row spaces, varieties and their interactions on plant height, spike length, spikelet number, grain number and grain yield measured in single plant
per main spike, fertile tiller number, total tiller (fertile + infertile ) number and biological yield in per single plant. In the study, other studied all
traits out of plant height highly increased as plant population was decreased. Maximum and minimum data were obtained from 15.0 cm and
normal of intra row spaces, respectively. Intra row spacing of 15.0 cm was lower 11.8% for plant height and higher 20.2% for spike length,
18.4% for spikelet number, 58.3% for grain number, 62.5% for grain yield, 694.4% for fertile tiller number, 647.0% for total tiller number and
991.9% for biological yield. Ahmetaga variety for all traits out of plant height was higher than Bezostaja-1 variety. Ahmetaga variety was greater
31.2% for fertile tiller number per single plant and 19.3% for grain yield in single plant per main spike. Ecological conditions affected highly
studied all traits.
