Abstract
The performance of autumn and spring-planted strawberry cv. ‘Elsanta’ in peat and peat supplemented with fresh spent mushroom substrate (SMS) of Agaricus bisporus, Lentinus edodes, and Pleurotus ostreatus in 15% and 25% was evaluated. The morphological and yield parameters, dry matter distribution, uptake, and partitioning of macro- and micronutrients were studied. The experiment was carried out during 2020–2021 in an unheated tunnel and was laid out in a randomised complete block design in five replicates. The study aimed to deliver greater insight into utilising fresh SMS as a sustainable substitute to peat. The shoot and root length, leaf number, crown diameter, plant dry weight, and marketable yields were superior in SMS-based substrates in autumn planting. The nutrient uptake varied among substrates and planting seasons, where higher plant nutrient uptake was noticed in SMS-based substrates. Nutrient partitioning among leaves, crowns, and roots was dynamic. The N, P, K, and Mn were mainly recovered in leaves. While Mg was almost equally partitioned among plant organs. The higher amounts of Na, Zn, and Cu were found in crowns. The greater accumulation of Ca and Fe in roots was evident. Correlation indicated that plant macro- and micronutrients had both positive and negative interactions. Overall, the superior morphological and yield performances of cv. ‘Elsanta’ were more noticeable in SMSs than in peat in autumn-planted strawberries.
