Impact of Coal-Ash Amended Soil on Growth, Yield and Photosynthetic Pigments of Cicer arietinum

Coal-ash, a by-product of coal burned, is rich in a variety of macro-and micro-nutrients and has a vast potential for use in agriculture as amendment. In the present study, the various levels of coal-ash (0.0, 10, 20, 30, 40, 50, 75 and 100%) were applied to soil to observe the impact on chickpea (Cicer arietinum) plant. All the parameters of growth, yield and photosynthetic pigments were increased significantly in 10%, 20%, 30% and 40% levels as compared to control. The level 30% was best for this crop. However, all the above parameters were reduced at 50%, 75% and 100% levels as compared to control.
