Field experiment was conducted at Horticultural College and Research Institute, Coimbatore during 2011-2012 to study the effect of drip fertigation of N, P and K with micronutrients. The results revealed that the fertigation treatments were significantly superior over the control. Among the treatments, application of NPK @ 100% RDF through fertigation using water soluble fertilizers + micronutrients registered the highest values for growth characters like plant height (4.68m), tree girth (56.22cm), tree spread north-south (4.24m) and east-west (3.49m) and specific leaf weight (1.16g cm2) at fruit development stage. The performance of 75% RDF by fertigation with water soluble fertilizers and micronutrients was on par with 100% RDF through fertigation using water soluble fertilizers + micronutrients for observed growth and yield parameters. The yield parameters like seed weight (8.01g), mace weight (3.44g), pericarp weight (54.48g), fruit weight (65.93g) and fruit yield plant-1 (121.37 kg) were the highest in 100% RDF through fertigation using water soluble fertilizers + micronutrients. The estimated fruit yield was the highest in 100% RDF through fertigation using water soluble fertilizers + micronutrients (18933.72 kg ha-1) and it was followed by with 75% level of N,P and K by fertigation using water soluble fertilizers with micronutrients (18120.96 kg ha-1). Higher values for the quality parameters viz., nut oil (9.22%), mace oil (9.81%), nut oleoresin (2.78%) and mace oleoresin (13.10%) were also high in 100% RDF through fertigation using water soluble fertilizers + micronutrients. Soil application of 100% RDF with flood irrigation without micronutrients (control) registered the lowest fruit yield of (54.35kg per plant-1).
