DSSAT Bitki Simülasyon Modeli ile Buğday’da Verim Tahmini

Abstract

Bu çalışmada 2018-2019 yılları arasında Mersin yöresi koşullarında gelecek yıllarda oluşabilecek iklimsel değişikliklerin belirlenebilmesi amacıyla Buğday bitkisinin bitki simlasyon modeline olan entegrasyonu incelenmiştir. Bu anlamda DSSAT bitki simülasyon modeline ait Ceres alt modelinin buğday bitkisinde kullanım durumu belirlenmiştir. Arazide elde edilen ve model tarafından kestirilen bitki boyu (cm), yaprak alan indeksi (cm2 cm-2), biyokütle (kg ha-1) ile verim (kg ha-1) değerleri karşılatırılarak %5 önem seviyesinde t testi uygulanmıştır. Araştırmanın her iki yılında da arazide ölçülen ve modelin kestirdiği anılan parametrelerde %5 önem seviyesinde farklılıklar görülmemişken yaprak alan indeksi değeri farklılık göstermiştir. DSSAT-Ceres bitki simülasyon modeli 2018 ve 2019 yıllaında sırası ile 5840-3970 kg ha-1 verim değeri elde ederken arazi ölçümleri ise 6220-3800 kg ha-1 şeklinde elde edilmiştir. DSSAT bitki simülasyon modelinin kalibrasyon sonucu elde edilen bitki genetik katsayıları ile buğday tahmini yapabileceği sonucuna varılmıştır.
