Pigeon pea [Cajanus cajan (L.) Millsp.] is the rich sources of dietary protein, carbohydrate & certain minerals, but its poor yield needs to formulate proper nutrient and pest management practices for higher productivity in upland alfisols of NEH regions and to combat it, an experiment was conducted during three consecutive kharif seasons at College of Agriculture, Lembucherra, Tripura comprising of eight nutrient and pest management combinations (T1-RDF (20: 60: 40); T2-T1+2% urea spray at 50% flowering; T3-T1+ 0.5% Borax spray at 50% flowering; T4- T1+ 0.5% ZnSO4 spray at 50% flowering; T5-T1+ 1% urea + 0.25% ZnSO4+ 0.25% Borax spray at 50% flowering; T6-T1+ Multimicronutrient spray @2 ml/litre at 50% flowering; T7-T1+ Indoxacarb at flowering + One systemic insecticide 15 days after the first spray; T8-T6+ Indoxacarb at flowering + One systemic insecticide 15 days after the first spray) in RBD design. It was revealed that micro-nutrient application in a combination of insecticide spray at flowering leads to better growth, higher yield (1.84 t/ha), and return per rupee (2.93), respectively.
•Low fertility and pest damage leads to a poor yield of pigeonpea in NEHR.
•Management through micro-nutrient and plant protection chemicals.
