Influence of Different Sources of Organic and Inorganic Fertilizers on Tomato (Solanum lycopersicum mill.) Growth, Quality and Soil Properties

Abstract

A pot culture experiment was conducted at the Experimental Farm located in Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir, Shalimar campus during kharif season 2018. This study was carriied out in Completely Randomized Design with three replications comprised of nine treatment combinations of sewage sludge (SS), aquatic weed compost (AWC) and inorganic fertilizers. However, in this study, it was initiate that the conjoint use of sewage sludge with chemical fertilizer (T5) recorded maximum build-up of soil macro nutrients (NPK), plant growth and quality parameters. However, the micro-nutrient concentrations in soil exposed to sewage sludge and aquatic weed compost were significantly higher than those in the untreated plots, with highest concentration found in sole application of sewage sludge (T3). All the micro nutrients studied were within the acceptable limits and did not overcome the maximum levels of phytotoxic. This experiment concludes that the application of sewage sludge and aquatic weed compost did not have any adverse impact on fruit quality and it was suggsetted to for the improvement of plant growth and soil fertilit

Municipal sewage sludge, aquatic weed compost on soil enzymatic activity and heavy metal accumulation in Kale (Brassica oleracea L.)

“…Sewage sludge (bio-solids) generation in Kashmir is increasing at a faster rate and waste water treatment facilities with enhanced efficiencies are being developed. Similarly, macrophytes are being harvested manually and mechanically, providing a source for compost production (Nazir et al 2021). These bio-solids and harvested aquatic weeds could easily be used for the restoration of soil fertility or for the production of quality vegetables, as they have good nutrient value (availability of NPK).…”
