Abstract:
Tomato (Solanum lycopersicon L.) is an annual vegetable crop of wide spread culture and popularity. Chemical fertilizers are used to increase the yield of crop whereas, continuous use of chemical fertilizers are synthetically manufactured in the factories and harm the useful microbes present in the soil and also decrease the soil fertility if used for longer time. In addition organic manures with inorganic fertilizers improve growth, yield and quality of tomato crop. Keeping this view in mind an experiment was carried out during Rabi 2022 at Agriculture Research Farm, Hajipur, Chandra Bhanu Gupta Agriculture PG College, B.K.T., Lucknow (U.P.). Nine treatments involving one variety F1 hybrid (Diamond) were trialed in randomized block design (RBD) with three replications. Total plots are twenty seven in numbers with 30X60 cm spacing. The transplanting of seedling was done on ridges and furrows at the distance of 30 x 60 cm. Results revealed that Maximum Dry matter content of fruit (g/plant) (5.56%), Minimum Days of first picking (66.00%), Minimum Days of 50% flowering (35.02%), Maximum no of fruit per plant (15.88) Maximum average fruit weight per plant 295.55 g, Maximum yield per ha (836.2 Q ha^-1) were found with treatment T₇ (50% RDF + 6.25 t/ha FYM + 0.62 t/ha Vermicompost + 0.41 t/ha Poultry Manure) at harvest stage of fruits which was followed by T6(75% RDF + 1.10 t/ha Poultry Manure). However in quality parameters, Maximum Total soluble solids (5.14°B),ascorbic acid content (23.34 mg/l00 g) was recorded with treatment T₇ (50% RDF + 6.25 t/ha FYM + 0.62 t/ha Vermicompost + 0.41 t/ha Poultry Manure) Whereas minimum values of these characters were found with controlT₉ and minimum acidity content (0.51%) was recorded with treatmentT₇.Among various treatments, treatment T7 (50% RDF + 6.25 t/ha FYM + 0.62 t/ha Vermicompost + 0.41 t/ha Poultry Manure) significantly gave better results in all parameters of growth, yield and quality respectively which was followed T₆ (75% RDF + 1.10 t/ha Poultry Manure) at respective stage of growth of crop significantly. This is due to availability of nitrogen. phosphorus and potash through organic and inorganic fertilizers resulting in better absorption of these nutrients by the tomato plant.
