Abstract:

This study aimed to investigate the effect of biogas digestate (BD) under different incubation times and different NPK levels on the growth and mineral nutrition of wheat. To this aim, 0, 15, and 30 tha-1 of BD were mixed into the soils. Afterwards, soils were kept at field capacity by irrigating twice a week for 0, 30, and 60 days. Then, the pots were fertilized with full (200, 100, and 125 mgkg-1) and half (100, 50, and 62.5 mgkg-1) NPK doses. The results showed that the available nutrient concentrations increased with the digestate and incubation. Although electrical conductivity (EC) increased with the treatments, it remained below the threshold level for healthy plant growth. Soil pH did not vary with the applications. The combination of full NPK, a digestate dose of 30 tha-1 and an incubation period of 60 days was the most effective treatment for dry weight (DW). Based on the examined parameters, it can be said that the most effective treatment in terms of plant growth and nutrient uptake was full NPK, 15 tha-1 BD, and a 60-day incubation period in general. The results also showed that NPK fertilization had a stronger effect on plant growth and nutrient uptake applied with digestate.
