Abstract
Municipal solid waste (MSW) generation and development of sodic degraded soil are two major environmental issues in India. The aims of present study to characterization of solid waste generated from Lucknow city which causes a serious issue with the management of garbage. The garbage was contained 46% of total MSW (1400MT/day) which decomposed openly and generates greenhouse gases responsible for global warming while salt affected soils are also worldwide problem. Sodic soils became unfertile or low crop productivity due to disturb soil morphology, very low organic carbon and nutrient imbalance which may be reclaimed by increasing organic carbon contents. In present study, garbage was managed through the vermi-technology and studied the effect of vermicompost on rhizomatous crops grown in sodic degraded soil. Sweet Flag (Acorus calamus) a rhizomatous crop was grown in sodic soils (pH 10.12)with different level of vermicompost i.e., T1act as control (100% soil), T2contains 75% soil and 25% vermicomposting (VC), T3contain 50% each soil and VC, T4contain 25% soil and 75% VC while T5contains 100% VC in a Completely Randomized Design (CRD).The results indicated that increasing the doses of vermicompost up to T4 considerably enhanced plant height, biomass yield and rhizome yield whereas at T5 this parameter were declined. When the dosage of vermicompost was increased, there was also a considerable increase in the anti-oxidative enzymes such as catalase and peroxidase vice versa photosynthetic pigments like chlorophyll (Chl.’a’, Chl.‘b’ and Total chl.) and carotenoid contents were increased. The total carbohydrates and sugar contents were also increased. The soil pH and exchangeable sodium percentage (ESP) were decreased while organic C contentwas increased which is an indicator of sodic soil reclamations.
