A field experiment was undertaken in the farmer’s field at Agadi village (Tq., Hubbli) in Dharwad district Karnataka India to investigate the relationship between index leaf nutrient concentration, yield and quality of Byadgi chilli influenced by calcium nitrate foliar spray. Two different concentration of calcium nitrate was foliar sprayed at different stages of chilli crop ( and Ca(NO3)2 and the experimental plot was laid out in randomized complete block design (RCBD) with twelve treatments and three replications. Result revealed that yield and quality attributes of chillies did not show any relationship with concentration of nutrients in index leaves before foliar spray of Ca(NO3)2 on 60 DAT but after foliar spray. Calcium content of index leaf showed significant positive correlation with yield (*) and colour value (*) and no relationship with oleoresin content. After spray at 75 DAT yield and quality attributes of red chillies were significantly and positively influenced by nutrient content of chilli leaves. But there is no correlation of P and Mg with yield and colour value. Foliar spray at 60 DAT closely synchronized with flower dropping and also colour development and oleoresin content in chilli fruits. | Relationship between index leaf nutrient concentration yield and quality of byadgi chilli (Capsicum annuum L.) influenced by calcium nitrate foliar application
