![]() ![]() Two main challenges in the cultivation of Sun mushroom are the compost nutrition and its long cultivation cycle 7, 8. Agaricus subrufescens along with Pleurotus eryngii, Flammulina velutipes and other non-Agaricus represented only 6% of the total production in Brazil.Ĭhanges in horticultural technologies are required to shift production from small-scale local producers to large-scale commercial production with international markets. 6 noted that the only country in the Americas that cultivated the Sun mushroom was Brazil. In the discussion of Agaricus these authors did not mention the Sun mushroom. 5 reported that world mushroom production is divided among several genera: Lentinula (22%), Pleurotus (19%), Auricularia (18%), Agaricus (15%), Flammulina (11%), Volvariella (5%) and others (10%). This species has been cultivated on a small-farm scale in Brazil for many years. One such mushroom is the Sun mushroom, reported as Agaricus subrufescens Peck, Agaricus brasiliensis Wasser et al. New species of medicinal mushrooms have emerged over the past decades. Rapid primordia induction allowed the crop cycle to end 3 days earlier than the slow primordia induction, providing a higher production rate. The ruffling technique provided an increase in biological efficiency due to the great number of mushrooms harvested. Champfood supplement promotes a reduction in the value of earliness and an increase of 1 st flush yield. Only the fat content of the mushrooms was positively affected by the rapid induction of primordia. Still the biological efficiency was not significantly affected by the mushroom induction temperature method. The highest yield harvested in any single day in the crop occurred in 3 rd flush with the amount of 2.484 kg of mushrooms per m 2 for the rapid induction method. Already biological efficiency was greater by 21%. Ruffling overall improved the yield in the 2 nd and 4 th flush. Among the supplements only Promycel increased the individual mushroom weight. Supplementation improved biological efficiency with Champfood providing a yield increase of 15% over the non-supplemented compost. Supplementation was beneficial for yield, unit mushroom weigh and decrease in time to first harvest. The research reported here evaluated the agronomic behavior and the chemical characteristics of the Sun mushroom as a function of i) nutritional supplementation ii) ruffling of the casing layer and iii) the temperature management on the primordia induction and reduction of the crop cycle. Horticultural improvements are required to shift its cultivation from small-scale local production to large-scale international production.
