Studies were conducted to evaluate leached sawdust as a casing substrate for the cultivation of Agaricus bisporus either alone or in combination with other substrates at College of Horticulture and Forestry, Neri, Hamirpur, Himachal Pradesh, India during the year 2018–2020. Out of seven casing media evaluated alone, coconut coir pith performed best in terms of all production parameters like time for spawn run (20.3 days) and pinning (15.7 days), sporocarps’ number (55.33), yield (0.679 kg 5 kg-1 compost) and biological efficiency (33.95%). The efficiency of sawdust- leached improved with the addition of other casing substrates. In commercial trial, combination of sawdust - leached with coconut coir pith, spent compost and farmyard manure (1:1v/v) performed better as compared to control (FYM+local soil), but a combination of sawdust- leached+coconut coir pith (1:1v/v) proved to be the best in terms of sporocarps’ number (88.00) and yield (1.271 kg 10 kg-1 compost) despite of the delay in time for spawn run (26 days) and pinning (24.3 days). Casing media also affected the biological efficiency of compost which varied from 10.50% in local soil to 34.05% in sawdust- leached+farmyard manure (1:1v/v) in different experiments. Cap diameter was recorded to be maximum (41.37 mm) in 2 years old spent compost and minimum (34. 27 mm) in sawdust- leached while, stipe length ranged from 14.17 mm in vermicompost-leached to 22.90 mm in sawdust- leached+farmyard manure (1:1v/v). However, fruit bodies harvested from all the casing treatments including standard check were found to be silky smooth and firm to compact.

The Impact

Abstract The cultivation of edible mushroom is an emerging sector with a potential yet to be discovered. Unlike plants, it is a less developed agriculture where many studies are lacking to optimize the cultivation. Mushrooms are a source of resources still to be revealed, which have applications not only in food, but in many other sectors such as health, industry and biotechnology. Mushroom cultivation consists of the development of selective substrates through composting where the mushroom grows via solid fermentation process. In case of Agaricus bisporus, the compost fully colonized by mycelium hardly produces mushrooms and it is necessary to apply a casing layer with certain physical, chemical and biological characteristics to shift from the vegetative mycelium to the reproductive one, where the native microbiota plays crucial roles. Currently, the industry faces a challenge to substitute the actual peat based casing materials due to the limited natural resources and the impact on the peatlands where peat is extracted.In this work we have employed high-throughput techniques by next generation sequencing to screen the microbial structure of casing soil employed in mushroom cultivation while sequencing V3-V4 of the 16S rRNA gene for bacteria and the ITS2 region of rRNA for fungi in an Illumina MiSeq. In addition, the microbiome dynamics and evolution (bacterial and fungal communities) in peat based casing along the process of incubation of Agaricus bisporus have been studied, while comparing the effect of fungicidal treatment (Chlorothalonil and Metrafenone). Statistically significant changes in populations of bacteria and fungi were observed. Microbial composition differed significantly based on incubation day, changing radically from the original communities to a specific microbial composition adapted to enhance the A. bisporus mycelium growth. Chlorothalonil treatment seems to delay casing colonization by A. bisporus. Proteobacteria and Bacteroidota appeared as the most dominant bacterial phyla. We observed a great change in the structure of the bacteria populations between day 0 and the following days. Fungi populations changed more gradually, A. bisporus displacing the rest of the species as the cultivation cycle progresses. A better understanding of the microbial communities in the casing will hopefully allow us to increase the biological efficiency during production as well as possibly help us to have a clearer view of the microbial community-pathogen relationships as they are directly related to disease development.

This study was carried out during 2012-2014 to determine the effect of locally available casing materials with association of bio-inoculant Pseudomonas putida. Six different combinations of casing mixtures were amended for evaluating its effect on yield, biological efficiency, protein and carbohydrate contents of Agaricus bisporus. A mixture of FYM + GLS + Vermi-compost + P. putida gave higher mushroom yield, biological efficiency, protein and carbohydrate content. It gave better yield (1306 g), biological efficiency (28.7%), protein (34.07%) and carbohydrate content (5.07%) respectively when compared with other treatments. In addition, waste tea leaves took minimum period (33.00 days) for initiation of pin head when compared with others. Locally available casing materials along with P. putida incorporated in the casing soil can be an important factor to obtain maximum and assured yield in mushroom cultivation.

Soil is the most preferred medium for growth of vegetation worldwide.An experimental investigation has been carried out to study the efficiency of a system to grow plants without the presence of soil called aquaponics .Aquaponics is the process of growing plants and fish and it is combination of hydroponics combined with aquaculture. Water from an aquaculture which is filled with nutrients is transferred to hydroponic system which is used by the plants as nutrient supplements and then the water is recycled back to the fish tank. Ammonia in fish waste will be broken down by bacteria which will be converted into nitrites and then to nitrates. Nitrates thus produced can be used as a natural fertilizer to grow plants.Two different types of aqua phonic grow mediumsuch as clay pebbles and coconut coir pith experimented and compared for two different crops usingaquaphonic technique.
