Effect of solid wastes amendment on growth and yield of Solanum melongena

Abstract

In the present study four different types of organic solid wastes namely: sugarcane waste, fish waste, flower waste and pineapple waste were selected and amended in soil. Plantation of saplings of Solanum melongena were done in the amended soil and changes in the growth pattern, biomass and soil characteristics were observed by comparing with unamended pots. It was observed that amendment of flower waste leads to an overall increase in the productivity of crop. On an average there was an increase of 11.7cm in height, 13 number of leaves, 5cm in root length and 3.4 g of biomass in the flower waste amended pots. Sugarcane and fish wastes amendment did not show positive impact on the crop. Pineapple wastes showed positive change. Soil moisture, organic C and N increased in all types of amendments. Available K increased only in flower and pineapple wastes amendment. There was significant correlation between crop and soil characteristics showing faster release of K in flower waste led to an increase in production of the crop.
