Experiment consisted of 12 treatments with three replications. Three foliar sprays of 1.5 per cent Ca(NO3)2 recorded highest fruit yield (21.76 q ha-1) followed by treatment that received one spray of 1.5 per cent Ca(NO3)2 at 45 DAT (21.38 q ha-1). Three foliar applications of 1.5 per cent Ca(NO3)2 recorded significantly highest colour value (280.22 ASTA units) and highest oleoresin content (20.39 %) which was on par with one foliar spray of Ca(NO3)2 (19.16 %) and 1.0 per cent on 75 DAT (16.98 %). Lowest flower drop (10.02 %) was recorded due to three foliar sprays of 1.5 per cent Ca(NO3)2 that was on par with one foliar spray given on 45 DAT as well as 60 DAT of same concentration. Uptake of calcium and magnesium were significantly influenced by foliar spray of Ca(NO3)2 and highest uptake was noticed due to three foliar applications of Ca(NO3)2 at 1.5 per cent. Nitrogen content of red fruit bears significant positive relationship with colour value (r= 0.681*) and oleoresin content (r=0.680*) while calcium content bears significant positive relationship with colour value (r=0.671*) and oleoresin content (r=0.768**). The B:C ratio was highest (5.98) due to three foliar application of Ca(NO3)2 at 1.5 per cent while lowest ratio (2.65) was in control. Foliar spray of 1.5 per cent Ca(NO3)2 is superior in improving the yield and quality of Byadgi chillies.EnglishThesis
