Abstract:
A study was conducted to find out seasonal effect of integrated nutrient management on spiny brinjal quality parameters and yield attributes. The spiny brinjal (Solanum melongena L.) var. VRM (BR)-1” experiment was conducted at Adhiparasakthi Agricultural College farm, Vellore District, Tamil Nadu. 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. Among the treatments the results clearly revealed that yield and quality parameters were highly recorded in T₁₁ and an economic assessment also highly recorded in treatment T_11.
