Biofortification of wheat straw with organic additives and its effect on morphological parameters and biological efficiency of Pleurotus ostreatus (Jacq.) P. Kumm
Keywords:
<i>Pleurotus ostreatus</i>, biofortification, organic additives, biological efficiencyAbstract
The experiment was conducted to evaluate the most effective organic supplement to enhance the morphological characters, yield and number of fruiting body per bag (NOFB) of Pleurotus ostreatus. Different organic additives viz., cereal flour (wheat, rice, maize), pulse flour (soybean, gram, chickpea, lentil and black gram) and cereal brans (wheat and rice) were evaluated on wheat straw. Wheat straw was supplemented with these additives at 2, 4 and 6% concentration and the results obtained revealed that the maximum number of fruiting bodies were recorded at 6% rice flour supplementation (30.73), maximum pileus diameter (7.84 cm) at 4% concentration, maximum stalk width at 2% concentration (1.92cm), highest biological efficiency (96.73%) was also recorded at 6% rice flour supplementation. It was observed that fortification of rice flour was beneficial in improving the morphological characters and yield of P. ostreatus. The results obtained in present investigations suggested supplementation of wheat straw with rice flour at 6% concentration is statistically superior over control and all other treatments.Downloads
