Abstract: An investigation was carried out on “Impact of inorganic and organic sources on bio- growth and nutrient accumulation in tomato crop”. The experiment was conducted in split plot design having two main plot (farmyard manure and pressmud compost), five subplot level of treatment (0, 5 10, 15, 20 MT ha^-1 organic manure along with RDF) with replicated thrice. Result revealed that highest fruit length and fruit diameter was recorded in the treatment T₃ (T₀ + 15 MT ha^-1 organic manure) which was at par with the treatment T₄ (T₀ + 20 MT ha^-1 organic manure). Whereas, significantly highest fruit yield (863.2 q ha^-1) was recorded in the treatment T₄ (T₀ + 20 MT ha^-1 organic manure) which was 21.5 and 31.70 per cent higher over T₁ (T₀ + 5 MT ha^-1 organic manure) and T₀ (Recommended dose of fertilizer), respectively. Maximum nitrogen (4.94%) and phosphorus (0.46%) content in fruit was found significant in the treatment T₄ (T₀+ 20 MT ha^-1 organic manure), whereas the potassium content was observed maximum in treatment T₄ (4.25%). Significantly higher uptake of nitrogen (237 kg ha^-1), phosphorus (22.1 kg ha^-1) and potassium (204.7 kg ha^-1) in fruit was observed in treatment T₄ (T₀+ 20 MT ha^-1 organic manure). Overall results indicated that combined application of inorganic and organic sources of farmyard manure and pressmud compost improve the nutrients content, uptake and bioaccumulation capacity and ultimately sustain the yield of tomato crop.
