Abstract
Current and predicted future climate changes are forcing specialists to find new food sources for the ever-growing population.
One of the most critical measures for the revival of the edible mushroom cultivation sector in Romania is the enrichment of the assortment.
In addition to their food value, mushrooms are also a profitable crop, ensuring a high production, obtained per unit of surface used in spaces designed for this purpose.
The compost, i.e., the nutrient substrate, must be suitable for the enzymatic possibilities and the energetic and nutritional requirements of the Agaricus mushrooms.
Thus, the conducted experience used four types of culture substrate (classical, synthetic, mixed and with reed) and two types of protein addition (wheat barn and corn flour). The experimental conditions were conducted and monitored using a Fancom computerized system for mushroom culture in the industrial system.
Analyzes of the culture substrates for each experimental variant and the harvested mushrooms, were carried out.
The highest production of carpophores, determined by the composition and method of compost preparation, was obtained on the synthetic compost substrate with an average value of 38.7 kg m‑2, exceeding the average production of the other compost variants.
Good production results (37.4 kg m‑2) were also obtained on the mixed compost.
Compost qualities and production effects can be essentially improved by adding a protein supplement to its composition.
The protein addition with wheat bran, in a proportion of 3%, provides an average increase in production of 7.2% in the synthetic compost and 11.2% in the mixed compost.
The food qualities of Agaricus brunescens Peck mushrooms, evaluated by the chemical composition, highlight that the product obtained on classic compost improved with the protein addition of corn flour.
Mushrooms harvested from this substrate have the highest values of carbohydrate content (58.63%).
