Bu çalışmada farklı dozlarda balık atığı kompostu uygulanmış mısır
bitkilerinin bazı büyüme ve fizyolojik özellikleri kimyasal gübre uygulanmış bitki
örnekleriyle karşılaştırılarak balık atıklarının biyolojik gübre olarak kullanılabilme
potansiyeli belirlenmeye çalışılmıştır. Balık atığı kompostu (BA) ve kimyasal gübre
Diamonyum Fosfat (DAP) kontrol, %25, %50 ve %75 oranlarında uygulanmıştır.
Bitki örneklerinde bitki boyu, toplam ağırlık, yaprak sayısı, yaprak alan indeksi,
gövde çapı, ilk koçan yüksekliği, kök uzunluğu ile mısır bitkisinin yaprak ve sap
örneklerinin alkol ile hazırlanan ekstraktlarında toplam fenolik madde, DPPH
radikali giderme aktivitesi ile Demir (III) indirgenme antioksidan güç (FRAP)
kapasiteleri belirlenmiştir. Ayrıca çalışmada kullanılan toprak örneklerinde CaCO3,
pH, EC, organik madde, alınabilir P, ve K analizleri yapılmıştır.
Çalışma sonucunda elde edilen morfolojik verilerin istatistiki analiz
sonuçlarına göre, bitki boyu uzunluğu, gövde çapı, kök ölçümü, yaprak sayısı,
toplam ağırlık ve yaprak ağırlığı değerlerinin balık atığı kompostu uygulamalarında
kimyasal gübreye göre yüksek ve istatistiki olarak önemli olduğu belirlenmiştir. Bitki
yapraklarından hazırlanan ekstraktların toplam fenolik içerik değerleri sap
kısımlarından daha yüksek bulunmuştur. Ayrıca fenolik madde içeriğinin
etüvlenmemiş yaprak ekstratlarında balık atığı kompostunun ve kimyasal gübrenin
doz artışına bağlı olarak arttığı görülmektedir. Etüvlenmiş olanlarda ise, kimyasal
gübre artışına bağlı olarak fenolik içerikte artış olduğu dikkat çekmektedir. Balık
atığı kompostu durumunda ise düzensiz bir değişim gözlemiştir. DPPH ve FRAP
değerleri fenolik içerik değerleri ile de uyumlu olacak şekilde değişkenlik
göstermektedir. Bu sonuçlar balık atığı kompostu uygulamasının önemli bir tarımsal
girdi olan gübre yerine alternatif olarak kullanılabileceğini göstermektedir.
Toprak analiz sonuçları değerlendirildiğinde killi, kuvvetli asidik, tuzlu ve
düşük organik madde içeriğine sahip olduğu görülmüştür.,In this study, some growth and physiological characteristics of maize plants
treated with different doses of fish waste compost were compared with plant samples
treated with chemical fertilizers, and the potential of using fish waste as biological
fertilizer was tried to be determined. Fish waste compost (FW) and chemical
fertilizer Diammonium phosphate (DAP) were applied in control, 25%, 50% and
75% ratios. Plant height, dry biomass, number of leaves, leaf area index, stem
diameter, first ear height, root length, in plant samples, and total phenolic substance,
DPPH radical removal in extracts of corn plant leaf and stem samples prepared with
alcohol. activity and Iron (III) reduction antioxidant power (FRAP) capacities were
determined. In addition, CaCO3, pH, EC, organic matter, available P, K analyzes
were made in the soil samples used in the study.
According to the statistical analysis results of the morphological data
obtained because of the study, it was determined that the plant height, stem diameter,
root measurement, number of leaves, dry biomass and leaf weight values were higher
and statistically significant in fish waste compost applications compared to chemical
fertilizers. The total phenolic content values of the extracts prepared from the plant
leaves were found to be higher than the stem parts. In addition, it was observed that
the phenolic content of the untreated leaf extracts increased depending on the dose
increase of fish waste compost and chemical fertilizer. Due to the increase in
chemical fertilizers, the increase in the phenolic content of the cured ones draws
attention. In the case of fish waste compost, an irregular change was observed. DPPH
and FRAP values vary in accordance with phenolic content values. These results
show that fish waste compost application can be used as an alternative to fertilizer,
which is an important agricultural input.
When the soil analysis results were evaluated, it was seen that it was clayey,
strongly acidic, salty and had low organic matter content.
