| dc.description.abstract | A study was carried out in Department of Soil Science and Agricultural Chemistry, University of Agricultural Sciences, Bangalore to assess and quantify lake biomass (LB), to prepare lake biomass compost (LBC) and to assess the effect of enriched LBC on growth and yield of French bean. Extent of LB was assessed using supervised classification of Landsat-9 satellite image. The study revealed the highest biomass of water hyacinth and alligator weed was found in Bellandur (11897.70 t ha-1) and Varthur (7398.89 t ha-1) lakes among the nine lakes. Water hyacinth (2.65, 0.65 and 2.73 % NPK, respectively) and alligator weed (2.63, 0.43 and 2.57 % NPK, respectively) was used as raw material for compost. LBC after three months was enriched with microbial consortium, neem cake and single super phosphate for 15 days which was evaluated with different levels of enriched LBC using French bean as a test crop. Significantly highest yield (0.99 kg plant-1) of French bean was observed with application of Microbial consortium + Neem cake + SSP enriched (MNSE) LBC + 100 % NPK followed by MNSE-LBC + 75 % NPK. The available nitrogen, phosphorus and potassium was medium and heavy metal concentration in soil was decreased after harvest of French bean. The results indicated that the application of enriched LBC serves as best source of nutrients to urban farmers and helps to address the issue of effective utilization of lake biomass which otherwise is a major concern. | en_US |
