Abstract

Gibberellic acid (GA3) was sprayed with eleven doses viz. 0, 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100 ppm at the primordia initiation stage to evaluate its effect on the growth and yield performance of Oyster Mushroom. At 10 ppm level GA3 gave the highest economic yield and dry weight. Application of GA3 increased the fresh economic yields to about 30% and 34%, while 80% and 115% dry weights increase occurred compared to the control at first and second harvests, respectively. GA3 showed a positive effect on number of effective fruiting body, stalk length, pileus diameter, biological yield, economic yield and dry economic yield. The result suggested that GA3 at 10 ppm/packet would be the best possible concentration for production of Oyster Mushroom. DOI: http://dx.doi.org/10.3329/jbau.v11i1.18196 J. Bangladesh Agril.

Highlights

Mushroom is popularly known as vegetable crop in the world
Pleurotus ostreatus commonly known as Oyster mushroom is gaining popularity and acceptability very fast among the farmers, because it can be grown all the year round under the climatic conditions of Bangladesh
Considering the importance of plant hormone on the yield of mushroom, the experiment was carried out to find out optimum concentration of GA3 for maximizing growth and yield of mushroom

Summary

Introduction

Mushroom is popularly known as vegetable crop in the world. Most recently it has occupied a very important place in human diet as a food item and has always been appreciated for its delicacy. The number of effective fruiting body varied significantly (Table1). While 50 ppm concentration produced the lowest number of fruiting body. The number of effective fruiting body varied significantly (Table 2) among different concentrations. The diameter of pileus varied significantly (Table 2).
