Abstract: A field experiment on was conducted during 2009 and 2010 to study the effect of intercropping, organic source of nitrogen substitution and graded levels of Potassium on the quality and oleoresin content of the bydagi chilli. The main treatment consisted of garlic and coriander intercropping and sole chilli and sub treatments consisted of five N substitution and graded levels of K viz., S1: N0P50K100 (entire N through organics), S2: N25P50K75 (75% N substitution through organics), S3: N50P50K50 (50% N substitution through organics), S4: N75P50K25 (25% N substitution through organics), S5: N100P50K0 (No substitution). Chilli + garlic intercropping system increased the dry chilli yield to the extent of 11.1 and 30 per cent and chilli equivalent yield to the extent of 57 and 48 per cent over chilli + coriander intercropping system and sole chilli. The yield attributes were also improved under garlic intercropping over sole chilli and chilli+ coriander intercropping system. The quality parameters such as oleoresin content and oleoresin yield, Ascorbic acid content, capsaicin content and Scovielle heat unit increased with chilli + garlic intercropping system compared to the chilli + coriander intercropping system and sole chilli.
