Bitki Gelişimini Teşvik Eden Rizobakterilerin Tarımda Kullanımı

Öz

Yoğun tarım, aşırı gübre kullanımını zorunlu kılmaktadır. Yüksek verim için fazla girdi kullanan tarım sistemleri çevresel problemlere ve doğal kaynakların tükenmesine yol açmaktadır. Gübre uygulamasını minimum, bitki gelişme ve beslenmesini maksimum düzeye çıkarmak amacıyla rizosferden seçilmiş farklı mikroorganizmalar kullanılmaktadır. Bitki gelişimini teşvik eden rizobakteriler (PGPR) bitki gelişimine faydalı etkileri nedeniyle biyolojik gübre (BG) olarak kullanılmaktadır. Biyogübreler sürdürülebilir tarım için büyük öneme sahiptir. Mikrobiyal türlerdeki geniş genetik varyasyon, farklı çevre koşullarına adapte olabilen yüksek potansiyele sahip mikroorganizmaların belirlenebileceğini ortaya koymaktadır. Bu nedenle geniş deneme koşullarında seçilecek etkin türlere gereksinin vardır.

Anahtar Kelimeler

• Biyolojik gübre (BG), Bitki gelişme promotörü rizobakteriler (PGPR), biyolojik azot fiksasyonu (BNF), inokulasyon, biyolojik kontrol
