Bu çalışmada farklı formda fosfor içeren gübrelerle birlikte uygulanan biyostimulantların fasulyede bitki gelişimi ve verimi üzerindeki etkileri araştırılmıştır. Çalışmada 6 farklı kombinasyondan oluşan uygulamalar [B1: Diamoyum fosfat (DAP), B2: DAP+humik asit (HA)+bakteri, enzim hormon (BEH), B3: kaya fosfat (KF), B4: KF+HA+BEH, B5: DAP+HA+BEH+salisilik asit (SA)+fulvik asit (FA) ve B6: KF+HA+BEH+SA+FA] bitki kök bölgesine topraktan uygulanmıştır. Uygulamaların bitki boyu, gövde çapı, yaprak alanı, bitki başına bakla sayısı, bitki başına bakla ağırlığı, bitki yaş ağırlığı, kök yaş ağırlığı, bitki kuru ağırlığı, kök kuru ağırlığı, klorofil içeriği ile yaprak mineral madde içeriği üzerine etkileri incelenmiştir. Ayrıca toprak mineral madde içeriği, pH, EC, kireç ve organik madde içerikleri de değerlendirilmiştir. Elde edilen sonuçlara göre uygulamalar arasında istatistiksel olarak önemli farklılıkların olduğu, farklı formda fosfor içeren gübrelerle birlikte uygulanan biyostimulantların bitkilerde kontrol bitkilerine göre bitki boyu, gövde çapı, yaprak alanı, bitki ve kök gelişimi, klorofil içeriği, bakla verimi, bakla sayısı ve bakla ağırlığı üzerinde olumlu yönde etkiler yaptığı tespit edilmiştir. Ayrıca bitki ve toprak mineral içeriğinde de uygulamaların iyileştirici etkisi belirgin olmuştur. Özellikle farklı kaynaklardan oluşturulan biyostimulant formülasyonlarının fosfor gübresi ile birlikte kullanımının fasulye bitkisinde bitki büyümesi, verim ve kalite yönünden olumlu etkiler sağlamasının yanı sıra gübre kullanım etkinliğini artırması ve sürdürülebilir tarımda uygulanabilmesi açısından faydalı olabileceği düşünülmektedir.

In this study, the effects of biostimulants applied together with different forms of phosphorus-containing fertilizers on plant growth and yield in bean were investigated. In the study, applications consisting of 6 different combinations (B1: Diammonium phosphate (DAP), B2: DAP+humic acid (HA)+bacteria, enzyme hormone (BEH), B3: rock phosphate (KF), B4: KF+HA+BEH, B5: DAP+HA+BEH+salicylic acid (SA)+fulvic acid (FA) and B6: KF+HA+BEH+SA+FA) were applied to the plant root zone through the soil. The effects of the applications on plant height, stem diameter, leaf area, number of pods per plant, pod weight per plant, plant fresh weight, root fresh weight, plant dry weight, root dry weight, chlorophyll content and leaf mineral content were investigated. Additionally, soil mineral content, pH, EC, lime and organic matter contents were also evaluated. According to the results obtained, it was determined that there were statistically significant differences between the applications and that biostimulants applied together with fertilizers containing different forms of phosphorus had positive effects on plant height, stem diameter, leaf area, plant and root development, chlorophyll content, pod yield, pod number and pod weight in plants compared to control plants. In addition, the amendatory effect of the applications on plant and soil mineral content has been evident. It is thought that the use of biostimulant formulations, especially those produced from different sources, together with phosphorus fertilizer will provide positive effects on bean plants in terms of plant growth, yield and quality, as well as increasing fertilizer use efficiency and being applicable in sustainable agriculture.
