RESEARCHES CONCERNING THE MANIFESTATION OF YIELDING POTENTIAL OF AGARICUS BISPORUS A-15 AND A –X STRAINS IN CASE OF USING DIFFERENT CONTAINERS FOR NUTRITIVE SUBSTRATE USED IN GROWING ROOM

Abstract

, , Romania, Keywords: SUMMARY The crop system used to grow mushrooms determines the way of introduction and placing of nutritive layer following several methods. At present, in the mushroom farms that use industrial intensive crop systems (bizonal and multizonal), there are differentiated systems with plain layers, cultures based on plyethylene bags or other types of containers using 2-4 story shelves, each having advantages and disadvantages. In the present paper, there are presented the research results regarding the effect of using the polyethylene bags and parallelepipedic bags made of same material in a mushroom farm with bizonal intensive system. The cultivation nutritive substrate was imported from companies profiled on compost preparation in the third phase (pasteurized, conditioned, inseminated with granulated mycelium and incubated). In one year, it was possible to perform 8 cultivation cycles (the duration of one cycle being of 46 days of which 40 days of harvest and 6 days for preparations requested for a new cultivation cycle). There were cultivated two types of mushroom strains, A-15 and A-x and nutritive substrate was treated against specific pests with Nemasys M product. The performed researches allowed us to conclude that mushroom yields obtained in case of using parallelepipedic PE foil bags were higher (33,3 %) comparatively with yields obtained on PE foil bags (30,6 %) and proved to be statistically covered. Moreover, mushroom yields obtained on both types of containers when Nemasys M product was applied (35,1 %) were higher than those obtained without applying Nemasys M product (29,3 %).
