Abstract/ Executive Summary:

The experiment was conducted to standardize optimum line to line and packet to packet spacing for obtaining best yield of the oyster mushroom (Pleurotus ostreatus ). Line spacing were 14, 17, 20 and 25 cm and packet spacing were 10, 11, 13, 14, 17, 20 cm. The effect of spacing was significant on growth, yield and yield components. Significant increase in the growth parameters and yield per packet was obtained with the increase of spacing up to certain limit and then decreased gradually. The highest economic yield per packet (189.10g) was obtained from 20 × 13 cm spacing whereas the highest economic yield per sq. m. (106.10g) area was obtained from 17 × 10 cm spacing. The highest benefit cost ratio (2.98) was obtained from 20 × 11 cm spacing.

Keywords: Growth, Yield, Oyster mushroom

Location: National Mushrooms Development and Extension Centre, Sobhanbug, Savar, Dhaka

Start Date: 00-10-2006

End Date: 00-01-2007

Program Area: Crop-Soil-Water Management

Commodity: Mushroom

Objectives:

To determine optimum line to line and packet to packet spacing for the highest growth and yield of Oyster mushroom in poly bag.

Methodology:

The experiment was conducted in the laboratory and the culture house of National Mushrooms Development and Extension Centre, Sobhanbug, Savar, Dhaka during the period of October 2006 to January 2007. Line to line distance (14, 17, 20 and 25 cm) and packet to packet distance (10, 11, 13, 14, 17, 20 cm) was tested as the treatment of the study. Pure culture, mother culture and spawn packets were prepared and cultural operation were done. The spawn packets of 500g were prepared using sawdust as substrate supplemen ted with wheat bran at 33.33% level. The temperature and relative humidity of the mushroom culture house was maintained by spraying water. The mean maximum temperature was 27 ºC and the mean minimum temperature was 18 ºC and maximum relative humidity was 90% and the mean minimum relative humidity was 41%. The mean maximum and minimum light intensities were 231 and 50 lux respectively. The cost of production was analyzed in order to find out the profitability of the treatment combination. All the non material cost and interest on running capital were considered for computing the cost of production. The interest on running capital was calculated at the rate of 12% per year for three months. The rent of the house was considered as per place and the price of mushroom at harvest was considered as Tk. 140/kg. The experiment was laid out in Randomized Complete Block Design (RCBD). The number of replication was 3 and the numbers of unit plot were 72. Treatments were randomly placed on the floor of culture house. Dimension of each unit plot was 1 m × 1 m. The unit plots and blocks were separated by a spacing of 0.2 m and 0.5 m respectively. Data on various parameters were statistically analyzed by using the ‘MSTAT-C’ program. Means were compared using Duncan's Multiple Range Test.

Achievement/Findings:

It was observed that the yield of mushroom per unit area was inversely related to the packet to packet and line to line spacing. The interaction effects between line to line and packet to packet spacing also showed significant influence and that was statistically identical to all other line to line and packet to packet spacing.
