Impact of fly ash soil amendment on seed germination, growth and yield of Vigna mungo L

Abstract

Fly ash is a byproduct from thermal power stations and posing a great problem of its disposal and so polluting the environment. In order to find out some solution a field experiment was conducted on Vigna mungo L. Hepper var. PU-19 to determine the effects of fly ash application on growth and yield characteristics. Various rates of fly ash (0, 5, 10, 15, 20, 25 and 30%) were applied in soil. Results of present investigation showed that fly ash application favoured plant growth. Plant height, number of leaves, branches and number of nodules plant-1 were increased with the application of fly ash up to 25% and thereafter, slight decline in all above parameters was recorded at 30% fly ash application. Harvest index, test weight and total yield were increased with fly ash application. Grain quality was also improved as total protein content was increased significantly by fly ash amendment. © Global Science Publications.
