The study utilized a Factorial Randomized Block Design (FRBD) to investigate the effect of fertigation levels and schedules on green chilli grown under protected conditions. There were twelve treatment combinations and each treatment was replicated thrice. The treatment includes two factors in this present experiment, the main factor consist of four fertigation levels i.e. 50%, 75%, 100% and 125% of RDF (112 : 37 : 37, 169 : 56 : 56, 225 : 75 : 75 and 281 : 94 : 94 NPK kg ha^-1). The sub-factor consist of three fertigation schedules i.e S₁-(60% NPK at vegetative stage i.e 2-42 DAT with 6 splits, 20% NPK at reproductive stage i.e 43-73 DAT with 4 splits, 20% NPK at maturity stage i.e 74-144 DAT with 10 splits), S₂-(40% NPK at vegetative stage i.e 2-42 DAT with 6 splits, 30% NPK at reproductive stage i.e 43-73 DAT with 4 splits, 30% NPK at maturity stage i.e 74-144 DAT with 10 splits) and S₃-(20% NPK at vegetative stage i.e 2-42 DAT with 6 splits, 40% NPK at reproductive stage i.e 43-73 DAT with 4 splits, 40% NPK at maturity stage i.e 74-144 DAT with 10 splits). The results indicated that, among fertigation levels, the application of 125% RDF through fertigation and among fertigation schedules, application of schedule S₃-(20% NPK at vegetative stage i.e 2-42 DAT with 6 splits, 40% NPK at reproductive stage i.e 43-73 DAT with 4 splits, 40% NPK at maturity stage i.e 74-144 DAT with 10 splits) was found to be best with respect to growth, yield and quality parameters of green chilli under protected conditions.
