Biyokömür İnkübasyonunun Buğday Verimi ve Bazı Verim Parametrelerine Etkisi

Öz

Araştırmada dört yıl inkübasyona bırakılmış biyokömürlerin buğdayın bazı verim ve verim öğelerine etkisini incelemek amaçlanmıştır. Bu amaçla 2017 yılında, dört saat boyunca 300, 500 ve 700 0C derecelerde piroliz edilmiş biyokömürlerden parseller dekara 3 ton olacak şekilde uygulama yapılmıştır. 2020-2021 yetiştirme döneminde ise bitki yetiştirme denemesi kurulmuştur. Deneme sonuçlarına bakıldığında, biyokömür uygulamalarının buğdayın vejetatif gelişmesini artırdığı, buna karşılık tane verimini azalttığı belirlenmiştir. Dahası, biyokömür uygulamaları hasat indeksi, başak boyu, bitki tane sayısı, kardeşlenme ve tane protein içeriklerini olumsuz etkilemiştir. Araştırmadan elde edilen bulgular göstermiştir ki, alkali bir toprağa uygulanarak uzun süre inkübasyona bırakılmış biyokömür buğdayın vejetatif gelişimini artırırken, tane verimini olumsuz etkilemiştir.

Effect of Biochar Incubation on Yield and Some Yield Parameters of Wheat

Abstract

This study investigated the effects of biochars on some yield and yield components of wheat after a four-year application. For this, biochars pyrolized at 300, 500, and 700C during four hours were applied to the plots at a rate of 3 t/da in 2017 and left for incubation for four years. In 2020-2021 growing season, plant growth experiment was planned. Experiment results showed that biochar applications enhanced wheat vegetative growth but the yield of grain decreased with biochar application. Moreover, the effect of biochar on some yield and quality criteria such as harvest index, ear length, plant grain number, tillering and grain protein ratio was negative. Findings from this study indicated that biochars incubated for a long time in an alkaline soil, increased the straw yield of wheat, but biochar had a negative effect on some grain yield and some yield parameters.
