EFFECT OF LIQUID SUPPLEMENT (WUXAL SUPER) ON THE YIELD AND PROXIMATE COMPOSITION OF OYSTER MUSHROOM (Pleurotus ostreatus)

Abstract

The experiment was conducted to study the effect of different levels of liquid supplement (wuxal super) on the yield and proximate composition of oyster mushroom (Pleurotus ostreatus). The experiment considered the following treatments: T 1 : Control (without wuxal super); T 2 : (wuxal super @ 0.1%); T : (wuxal super @ 0.2%); T 4 : (wuxal super @ 0.3%); T : (wuxal super @ 0.4%). Data on different growth, yield contributing characters, proximate composition of 5 mushroom were recorded and statistically significant variation was observed for different treatments. The Lowest time from stimulation to primordial initiation (3.20 days) and primordia initiation to harvest (3.60 days) was observed in T

treatment .The highest number of primordial/packet (71.20) was observed in T treatment while the highest weight of individual fruiting body/packet was observed in T (3.52g). The highest biological yield (261.56 g/packet), economic yield (252.96 g/packet), dry yield (37.34 g/packet) and biological efficiency (186.83%) were recorded in the T 4 treatment. The highest moisture percent was observed in T 3 4 (88.70%) and the highest dry matter percent was observed in T

(13.76%).Among the biochemical attributes the highest content of protein was recorded in T 4 (25.19%). The lowest lipid content was obtained in T (3.17%), the highest percentage of ash was observed in T (8.60%).The highest carbohydrate

4 3 3 4 5 4 content was recorded in T 1 (40.15%), whereas the lowest was observed in T (31.83%). The highest percentage of nitrogen (4.03%), potassium (1.98%), calcium (1.97mg/100g), and zinc (15.17mg/100g) was recorded in T treatment. Therefore it can be concluded that wuxal super @ 0.3% was found as an efficient supplement to increase the yield of oyster mushroom. 4 4
