EFFECT OF DIFFERENT LEVEL OF LIQUID MINERAL SUPPLEMENT (WUXAL SUPER) ON THE YIELD AND NUTRITIONAL STATUS OF OYSTER MUSHROOM (Pleurotus ostreatus) Biswas, Samaren The present study was carried out at the Biochemistry laboratory and Mushroom Culture House (MCH)of Biochemistry Department, Sher-e-Bangla Agricultural University, Dhaka, during the month of January to May ’09 to investigate the yield performance of oyster mushroom supplemented with different levels of liquid minerals. All the treatments performed significantly over the control. The lowest time from stimulation to primordia initiation (5.2 days) and primordia initiation to harvest (3.9 days) was observed in T 4 (Wuxal Super @ 0.3%). The highest number of primordia/packet (66.33) was observed in the T and the highest number of fruiting body/packet was observed in T 3 2 (70.00) while the highest weight of individual fruiting body was observed in T (2.25g). The highest biological yield (129.0 g/packet), economic yield (123.7 g/packet) dry yield (12.73 g/packet) and biological efficiency (44.48%) was recorded in the T 4 (Wuxal Super @ 0.3%). The study also investigate the effect of liquid mineral supplements on nutritional status the highest moisture percent was observed in T 4 (90.44%) the highest dry matter percent was observed in T 4 3 (10.30%). Among the biochemical attributes the highest content of protein was found in T (23.60%), lowest lipid percentage was counted under T 3 4 (5.16%), the highest percentage of ash was observed in T (9.60%), the highest percentage of carbohydrate was recorded in T highest percentage of crud fiber was recorded in T (29.70 %). Therefore there was not much effect of the treatments on biochemical properties of produced mushroom. In case of elemental composition the highest percentage of nitrogen was recorded in the T 4 4 (3.78) while highest percentage of phosphorus (0.96), potassium (1.44) and iron (43.67) was recorded in T and the the highest amount (mg) of manganese (2.80) and zinc (14.17) was counted under T 3 There fore it can be concluded that wuxal super @ 0.3% is found as a efficient supplement for mushroom production lowering the cost increasing yield. 5. 1 (46.07%) and 5 A Thesis Submitted to the Faculty of Agriculture, Sher-e-Bangla Agricultural University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE (M.S.)

EFFECT OF DIFFERENT LEVELS OF COW DUNG WITH SAWDUST ON YIELD AND PROXIMATE COMPOSITION OF OYSTER MUSHROOM (Pleurotus ostreatus) Kulsum, Ummey The present study was carried out at the Biochemistry laboratory and Mushroom Culture House (MCH) of Department of Biochemistry, Sher-e-Bangla Agricultural University, Dhaka, during the month of February to July’09 to determine the effect of different levels of cow dung as supplement with sawdust on the performance of oyster mushroom. All the treatments perform better over control. Mycelium running rate in spawn packet and highest average number of primordia/packet was found to be differed due to different levels of supplements used. The highest average weight of individual fruiting body was observed in sawdust supplemented with cow dung @ 10% (3.69 g). The supplementation of sawdust with cow dung had great effect on biological yield, economic yield and Dry yield, biological efficiency, cost benefit ratio. The highest biological yield (254.7 g), economic yield (243.3 g) and Dry yield (23.40 g) biological efficiency (87.82%), cost benefit ratio (8.29) was counted under sawdust supplemented with cow dung @ 10%. Among the chemical characteristics highest content of protein, ash, crud fiber (24.07) was found in treatment T 4 , on the other hand lowest lipid (3.90 %) and carbohydrate (32.57) percentage was counted under treatment T . Among the minerals highest amount of nitrogen (4.85), potassium (1.39), calcium (22.08), magnesium (20.21), sulfur (0.042), iron (43.11) and lowest phosphorus (0.92) was counted under sawdust supplemented with cow dung @ 10%. There fore it can be concluded that cow dung @ 10% with saw dust may be an alternative supplement to produce oyster mushroom for better cost benefit management.

STUDY ON PREPARATION OF LOW COST SPAWN PACKETS FOR THE PRODUCTION OF OYSTER MUSHROOM (Pleurotus ostreatus) AND ITS PROXIMATE ANALYSIS BHOYAN, M. H. M. BORHANNUDDIN The effect of various supplements at di fferent levels with sawdust showed significant effort on mycelial running rate and reduced the required days to complete mycelium running in the spawn packet. The supplementation of sawdust found to be significant in yield and yield contributing characters of oyster mushroom with some extent. The highest biological yield. economic yield, dry yield, biological efficiency (BE) and benefit cost ratio (BCR) of 270.5g, 266.5g, 26.34g, 93.29, 9.57%. respectively was observed in sawdust supplemented with NPK mixed fertilizer (N=O.6%, P=O.3%, K=O.3%). Sawdust supplemented with different levels has a profound effect on chemical composition of oyster mushroom. Sawdust supplemented at different substrate found to be significant with mineral content of the fruiting body. Considering all the parameters in five experiments, NPK mixed fertilizer (N=O.6%, P=O.3%. K=O.3%) supplemented with sawdust is found promising for lowering the cost of production as well as increasing the yield and quality of fruiting body. Cow dung (11.5%) and starch (5.5%) as supplement with substrate may be the fair choice. MASTER OF SCIENCE (M.S.) IN BIOCHEMISTRY SEMESTER: JANUARY -JUNE' 08
