Yield Performances of Some Rice Varieties According to Land Suitability Classes

Abstract

This study was conducted in order to determine the yield performanses and qualities of 12 rice varieties (Osmancık 97, Neğiş, Aromatik-1, Beşer, 7721, Halilbey, Gönen, Karadeniz, Kızılırmak, Koral, Durağan ve Şumnu) in areas of Kızılırmak town having suitable (S2) and less suitable(S3) classes for two years (2009 and 2010). Experiments were established in RCB design with 3 blocks. The highest yield in S1 class was 0.8469 t/ha and obtained from Kızılırmakvariety .This was followed by Halilbey variety with 0.8069 t/ha. As the highest yield was obtained from Halilbey variety with 0.8407 t/ha in the area of S2 class, it was 0.5808 t/ha with 7721 variety in S3 land suitability class. The average yields of S1, S2 and S3 land suitability classes were 0.7056, 0.6930 and 0.4461 t/ha, respectively. During the study, grain yield, plant height, bunch length, seed number per bunch, thousand kernel weight and lodging and unbroken kernel rate were investigated separately.
