Abstract


Oyster mushroom is an attractive mushroom due to its unique appearance and fragrance. The trial was conducted in medicinal and mushroom lab, Institute of Horticultural Sciences, University of Agriculture, Faisalabad. Carrot leaves substrates used in combination with cotton waste for production of two strain of oyster mushroom Pleurotus sajor caju (P-3) and Pleurotus sapidus (P-6). By using different types of combinations of carrot leaves and cotton waste viz T0= cotton waste (100%) control, T1= Carrot leaves (100%), T2= Carrot leaves (75%) + Cotton waste (25%), T3= Carrot leaves (50%) + Cotton waste (50%), T4= Carrot leaves (25%) + Cotton waste (75%) and T5 = Carrot leaves (12.5) + Cotton waste (87.5%) as a substrate.  The experiment was laid out according to two factors factorial under completely randomized design (CRD).Different parameters such as initiation of spawn running, initiation of mycelium growth, number of days to complete mycelium growth, pinhead formation, number of pinhead, number of days to complete number of flushes (1st, 2nd and 3rd), fresh weight of mushroom, yield per bag, biological efficiency, nitrogen, phosphorus and potassium contents of substrate prior to and after attaining mushroom crop, total soluble solids, acidity, ascorbic acid contents and moisture (%) were studied. Collected data was analyzed statistically by using the analysis of variance technique. LSD test 5% probability was applied to compare the difference among the treatment means. Results indicated that initiation of spawn running, initiation of mycelium growth, number of days to complete mycelium growth, pinhead formation, number of pinhead, number of days to complete number of flushes (1st, 2nd and 3rd), fresh weight of mushroom, yield per bag, biological efficiency, moisture (%), nitrogen contents of substrate after cropping, phosphorus contents of substrate after cropping and potassium contents of substrate after cropping were significantly influenced by treatment (T2) as compared to control.  Additionally, total soluble solids, nitrogen contents of substrate before cropping and potassium contents of substrate before cropping were significantly influenced by treatment (T1) as compared to other treatments. Furthermore, treatment (T0) significantly affected acidity (%) and ascorbic contents of mushroom. Moreover, total sugars (%), reducing sugars (%) and non-reducing sugars (%) were significantly affected by treatment (T4) as compared to other treatments. It is concluded from our research work that cotton waste supplemented with various concentration of carrot leaves give a positive result as compared to control. Overall results showed that maximum parameter was given significant results on cotton waste supplemented with (T3) 50% carrot leaves for strain (P-3).
