Description A field experiment was conducted at the Main Agricultural Research Station,
College of Agriculture, UAS, Dharwad during rabi 2009-10 to study the influence of
organics on growth, yield and quality of tomato (Lycopersicum esculentum L. Mill.).
The experiment was laid out in a randomized block design in 14 treatments with 3
replications. Treatments include different organic sources of nutrients i.e. compost,
FYM, green leaf manure, poultry manure, sheep manure and vermicompost alone and
their combinations compared with RDF alone and RDF+FYM.
The morphological characters mainly total dry matter accumulation, plant
height, number of branches, canopy spread, leaf area and physiological parameters
like leaf area index (LAI), leaf area duration (LAD) and biomass duration (BMD)
were significantly higher with RDF+FYM, organics mainly FYM, compost, poultry
manure and sheep manure applied equivalent to RDN as compared to only inorganic
fertilizer, green leaf manure and control in all growth stages.
The growth parameters like AGR and CGR were highest with the application
of RDF+ FYM followed by poultry manure at 30 to 60 DAT, while at 60 to 90 DAT
AGR and CGR were higher with the application of poultry manure combined with
vermicompost. The net assimilation rate, photosynthetic rate and chlorophyll contents
were higher with the application of RDF+FYM followed by poultry manure, which
were on par with other organic manures except green leaf manure and its combination
with vermicompost.
The quality parameters like ascorbic acid content, reducing sugar content,
lycopene, protein content, pH, TSS and shelf life were significantly higher with the
application of poultry manure. The fresh fruit yield of tomato was found superior with
the application of RDF+FYM followed by poultry manure, all other organic manure
shows on par results except green leaf manure and combination with vermicompost,
RDF only and control. Net returns were significantly higher with RDF+FYM, on par
with rest of the treatments except green leaf manure, RDF and control.
