Naya kheda is one of the coal fly ash affected land areas around Kota city
due to spread of thin layer of CFA from Kota Super Thermal Power Station (KSTPS).
The productivity and fertility of land is badly affected for number of local crops. A
great amount of elements (C,N,P, K, Ca, Mg, Cu, Zn and Mn) get into the soil.
Therefore, in view of improvement of fertility or amelioration of surface soil of the
area physicochemical studies have been carried out with surface soil of the area and
different composts prepared by mixing sugarcane waste (SCW) with this surface soil
in different proportions. Sugarcane waste was used to add with organic part and to alter
physicochemical properties of the surface soil. Pot experiments were conducted to
study the effect of different proportions of sugarcane waste on soil properties in
cultivation of Solanum melongena. According to the best results obtained from the pot
experiments, field experiments were also carried out. A significant increase in growth,
rate of growth and quality of produce was observed on cultivation of Solanum
melongena in surface soil amended with 50% (v/v) sugarcane waste. In other words,
sugarcane waste worked as best ameliorating material in 50% (v/v) proportion with
CFA affected surface soil after conversion into compost. In amended soils an increase
in the content of N, K, Ca, Mg, S, Fe, Mn, Zn and Cu and improvement in physical
properties was observed.
