Farklı sıcaklıklarda üretilen çeltik kavuzu biyokömürünün kurak koşullarda toprak özellikleri ve marul bitkisi verimine etkileri

Öz

Bu çalışmanın amacı, artan su stresi koşulları altında farklı piroliz sıcaklıklarında (350°C ve 550°C) üretilen çeltik kavuzu biyokömürünün marul (Lactuca sativa L.) bitkisinin verimi ve fizyolojik parametreleri ile toprak özellikleri üzerindeki etkilerinin araştırılmasıdır. Sera koşullarında, tesadüf parsellerinde faktöriyel deneme desenine göre kurulan çalışmada; üç farklı sulama rejimi (%50, %75 ve %100), iki farklı biyokömür tipi (B350 ve B550) ve üç farklı biyokömür dozu (%0, %1 ve %2) test edilmiştir. Elde edilen bulgular, artan sulama suyu seviyelerinin ve biyokömür dozlarının marulun taze ve kuru biyokütle verimi ile su kullanım randımanını istatistiksel olarak ileri düzeyde (p<0.01) artırdığını göstermektedir. Biyokömürün üretim sıcaklığının verim parametreleri üzerinde istatistiksel açıdan anlamlı bir ana etkisi bulunmamasına rağmen, %2 oranındaki biyokömür uygulaması kontrol grubuna kıyasla taze verimde %24, kuru verimde ise %30'luk bir artış sağlamıştır. Toprak özellikeri açısından değerlendirildiğinde, %2'lik biyokömür dozu toprağın değişebilir potasyum ve alınabilir fosfor konsantrasyonlarını sırasıyla %24 ve %18 oranında artırmıştır. Sonuç olarak bu çalışmada, çeltik kavuzu biyokömürünün üretim sıcaklığından bağımsız olarak %2 oranında toprağa uygulanmasının, kuraklık baskısı altındaki tarımsal sistemlerde su kullanım randımanını optimize etmek, bitki verimini korumak ve toprak verimliliğini sürdürülebilir bir şekilde artırmak için etkili, ekonomik ve çevre dostu bir strateji olduğu vurgulanmıştır.

Effects of rice husk biochar produced at different temperatures on soil properties and lettuce yield under drought conditions

Öz

This study aims to evaluate the effects of rice husk biochar produced at different pyrolysis temperatures (350°C and 550°C) under increasing water stress conditions on the yield and physiological parameters of lettuce (Lactuca sativa L.) as well as on soil properties. Conducted under greenhouse conditions using a factorial experimental design in randomized blocks, the study tested three different irrigation regimes (50%, 75%, and 100%), two different biochar types (B350 and B550), and three different biochar application rates (0%, 1%, and 2%). The findings indicate that increasing irrigation water levels and biochar application rates significantly (p<0.01) increased the fresh and dry biomass yields of lettuce as well as its water use efficiency. Although the production temperature of biochar had no statistically significant main effect on yield parameters, the application of 2% biochar resulted in a 24% increase in fresh yield and a 30% increase in dry yield compared to the control group. In terms of soil properties, a 2% biochar application increased the soil’s exchangeable potassium and available phosphorus concentrations by 24% and 18%, respectively. In conclusion, applying 2% rice hull biochar to the soil—regardless of production temperature—is an effective, economical, and environmentally friendly method for optimizing water use efficiency, maintaining crop yield, and sustainably increasing soil fertility in agricultural systems under drought stress..
