S.B. AGRAWAL, ANOOP SINGH AND MOHD M. BHAT

Abstract

Fly ash is a byproduct from thermal power statons and posing a great problem of its disposal and polluting the environment. In order to find out some solution a field experiment was conducted CO ligna L. flepper var. PU-19 to determine the effects of fly ash application on growth and yield c.harar:teristics. Various rates of fly ash (0, 5,10, 15, 20, 25 and 30%) were applied in soil. Results of present investgation showed that fly ash application favoured plant growth. Plant height, number of leaves, branches and number of nodules plant' were 'increased with the application of fly ash up to 25% and thereafter, slight decline in all above parameters was recorded at 30% fly at awl:43ton. Harvest index, test weight and total yield were increased with fly as application Grain quality was also improved as total protein content was increased significantly by fly ash amendment
