The trial was conducted in mushroom lab, Institute of Horticultural Sciences, University of Agriculture, Faisalabad to study the possibility of carrot pomace substrate utilization in combination with cotton waste for production of two strains of king oyster mushroom. Two different strains (P9) or (P10) were used to evaluate the growth potential and behavior of yield. Different combination of carrot pomace were used with cotton waste i.e. T0= Cotton waste (100%) control, T1= Carrot pomace (100%), T2= Carrot pomace (75%) + Cotton waste (25%), T3= Carrot pomace (50%) + Cotton waste (50%), T4= Carrot pomace (25%) + Cotton waste (75%) and T5= Carrot pomace (12.5%) + Cotton waste (87.5%). Different parameters such as time for beginning of spawn running (days), mycelial growth (days) completion time, time for initiation of pinhead formation (days), per bag Pinheads/ No, per bag flushes/ No, 1st, 2nd and 3rd flush completion days, weight of 1st, 2nd, and 3rd flushes of fresh mushroom, Per bag Yield (g), biological efficiency (%), TSS (Brixo), moisture % , total sugar (%), reducing sugars (%), non-reducing sugars (%), acidity and ascorbic acid contents were studied. Results indicated that all other above-mentioned parameters were significantly influenced by treatment (T4) and (T5) as compared to controlResults indicated that number of days to complete mycelial growth, number of days to complete number of flushes (1st, 2nd and 3rd), pinhead formation, number of pinhead, TSS, reducing sugars, non-reducing sugars were significantly influenced by treatment (T4) as compared to control. Moreover, fresh weight of mushroom and biological efficiency were significantly affected by (T5) as compared to other treatments. Furthermore (T3) treatment were significantly influenced potassium contents of substrate before cropping, number of pinheads/bag, nitrogen contents of substrate before cropping and ascorbic acid contents of mushroom.
