Nano urea effects on Pleurotus ostreatus nutritional value depending on the dose and timing of application

Abstract The work investigated the effect of Lithovit-Urea50 on the composition of Pleurotus ostreatus (Jacq. Ex Fr.) P. Kumm. (1871) cultivated on spent oyster substrate mixed with wheat straw (1:1, w/w mixture). The product was applied in different doses (C1: 3 g kg−1 and C2: 5 g kg−1) at three di...

Protein and fiber contents increased respectively by 0.64 and 0.2% in C1t1 and by 0.46 and 0.8% in C2t2 compared to control (C0t0). Total carbohydrates increased by 0.48–3.76%.
