Background: An experiment on “Effect of Integrated Nutrient Management on Growth, Yield Attributes and Economics of Spiny Brinjal (Solanum melongina L.) var. VRM (Br)-1” were conducted at Adhiparasakthi Agricultural College farm, Vellore District, Tamil Nadu.

Methods: Eleven treatments of integrated nutrient management viz., T₁-RDF of N:P:K (100:50:30 kg/ha.), T₂– FYM (25 t/ ha.), T₃- Humic acid (20 kg/ha.), T₄- RDF of N:P:K (100:50:30 kg/ha.) +FYM @25 t/ ha, T₅- Humic acid (20 kg/ha.) + RDF of N:P:K (100:50:30 kg/ha.), T₆- Azospirillum (2 kg/ha.), T₇- Phosphobacteria (2 kg/ha.), T₈- Azospirillum (2 kg/ha.) + Phosphobacteria (2 kg/ha.), T₉ – 75% RDF of N (75 kg/ha.) + 100% RDF of P&K (50:30 kg/ha.) + Azospirillum (2 kg/ha.), T₁₀ - 75% RDF of P (37.5 kg/ha.) + 100% RDF of N&K (100:30 kg/ha.) + Phosphobacteria (2 kg/ha.) and T₁₁ - 75% RDF of N & P (75:37.5 kg/ha.) + 100% RDF of K (30 kg/ha.) + Azospirillum (2 kg/ha.) + Phosphobacteria (kg/ha.) replicated thrice in Randomised block design.

Results: The various treatments of integrated nutrient managementin spiny brinjalclearly showed that growth and yield attributes were high in T_11.The economic assessment of different treatments revealed that maximum net profit Rs.2,16,570/ha.with benefit cost ratio (2.60) was also recorded in treatment T₁₁ 75% RDF of N & P (75:37.5 kg/ha.) + 100% RDF of K (30 kg/ha.) + Azospirillum(2 kg/ha.) + Phosphobacteria (kg/ha.).
