Potential utilization of spent Agaricus bisporus mushroom substrate for seedling production and organic fertilizer in tomato cultivation

Abstract

The production of Agaricus bisporus results in significant residual material after cultivation. Due to its physical properties and nutrient content Spent Mushroom Substrate (SMS) has great potential for use in agriculture. Our study evaluated the feasibility of using SMS as an alternative substrate for the production of Paronset® hybrid tomato seedlings and as an organic fertilizer in its production. To conduct the fruit production experiment, the plots consisted of three types of fertilizers (SMS of A. bisporus, NPK and bovine manure) with four replications. The seedlings produced in the SMS presented higher rates of germination time and speeds, and stood out from the other substrates in the evaluation of seedling quality. In the tomato fruit production phase, the average production of the plants originating from the SMS was 20% higher than the seedlings from the commercial substrate. The plants cultivated with the SMS presented higher production than the plants cultivated with bovine manure incorporated the soil. According to our results, The SMS was as good as the commercial substrates tested. Therefore, the SMS can be recommended for the growth and nutrition of seedling production and denotes potential viability for use in the tomato production cycle in its different phases.

Potential of Pleurotus sajor-caju compost for controlling Meloidogyne incognita and improve nutritional status of tomato plants

“…The present results are in agreement with some previous studies, which indicate the viability of using MC as an organic fertilizer for growing tomato plants [67][68][69]. Similarly, Pant and Singh, et al [59] reported that spent compost of P. sajor caju was effective for improving tomato growth parameters and soil fertility.…”

“…Whereas, the signi icantly lowest value of fruit yield/plant was recorded with the untreated plant in both seasons. Many authors greatly supported our indings [19,26,59,69]. They found that MC was effective as soil amendments for improving tomato growth performance and fruit yield.…”

Control of Meloidogyne javanica with Pleurotus djamor spent mushroom substrate

“…The results of this treatment are not reported because such effects culminated in plant death. Agaricus bisporus substrate had a similar effect on tomato seedlings, causing a 2-day delay in germination (Collela et al 2019).…”

Reuse of post-culture mushroom substrate in horticultural seedbeds

“…The sensitivity of the vegetable crop can be determinant for the response of the crop to the substrate used, Collela et al [30] used SPCH-St as a seedling substrate and obtained vigorous and quality tomato seedlings as in the commercial substrates tested. Also the use of SPCH mixed with anaerobic digestion residues produced good results in vegetable seedlings for tomato and bell pepper [31] .…”
